Vessel Incidental Discharge National Standards of Performance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The U.S. Environmental Protection Agency (EPA) is promulgating
a regulation under the Vessel Incidental Discharge Act that establishes
Federal standards of performance for marine pollution control devices
for discharges incidental to the normal operation of primarily non-
Armed Forces and non-recreational vessels 79 feet in length and above
into the waters of the United States or the waters of the contiguous
zone. The Federal standards of performance were developed in
coordination with the U.S. Coast Guard (USCG) and in consultation with
interested Governors. The final standards, once made final, effective,
and enforceable through corresponding USCG regulations addressing
implementation, compliance, and enforcement, will control the discharge
of pollutants from vessels described above and repeal certain existing
Federal, State, and local vessel discharge requirements, thus
streamlining regulation of such vessel incidental discharges. EPA is
also promulgating procedures states must follow if they choose to
petition EPA to require the use of an emergency best management
practice to address aquatic nuisance species (ANS) or water quality
concerns (``emergency order''), to review any standard of performance,
regulation, or policy, to request additional requirements with respect
to discharges in the Great Lakes, or to apply to EPA to prohibit one or
more types of vessel discharges regulated by this rule into specified
waters to provide greater environmental protection.
DATES: The effective date of this rule is November 8, 2024. The Federal
standards of performance, however, become effective beginning on the
date upon which the regulations promulgated by the Secretary pursuant
to CWA section 312(p)(5) governing the implementation, compliance, and
enforcement of the Federal standards of performance become final,
effective, and enforceable. Per CWA section 312(p)(3)(c), as of that
date, the requirements of the VGP and all regulations promulgated by
the Secretary pursuant to section 1101 of the NANPCA (16 U.S.C. 4711)
(as in effect on December 3, 2018), including the regulations contained
in subparts C and D of 33 CFR part 151 and 46 CFR 162.060 (as in effect
on December 3, 2018), shall be deemed repealed and have no force or
effect. Similarly, as of that same date, any CWA section 401
certification requirement in Part 6 of the VGP, shall be deemed
repealed and have no force or effect.

I. Executive Summary
Discharges incidental to the normal operation of a vessel, as
defined in 33 U.S.C. 1322(a)(12), are referred to as ``incidental
discharges'' or ``discharges'' in this publication for convenience.
Incidental discharges contain pollutants that can adversely impact
aquatic ecosystems and human health. Pollutants that may be found in
these discharges include aquatic nuisance species (ANS), nutrients,
bacteria or pathogens (e.g., Escherichia coli and fecal coliform), oil
and grease, metals, as well as other toxic, nonconventional, and
conventional pollutants (biochemical oxygen demand (BOD), total
suspended solids (TSS), pH, fecal coliform, and oil and grease). These
pollutants can have wide-ranging environmental and human health
consequences that vary in degree depending on the type and number of
vessels operating in a waterbody and the nature and extent of the
discharge.
The Federal Water Pollution Control Act Amendments of 1972 \1\
(commonly known as the Clean Water Act (CWA)), the Nonindigenous
Aquatic Nuisance Prevention and Control Act (NANPCA), the Act to
Prevent Pollution from Ships (APPS), and several other Federal, State,
local, and international authorities have established over time various
requirements for both domestic and international vessels. To clarify
and streamline existing requirements, in December of 2018, the Vessel
Incidental Discharge Act (VIDA) was signed into law. The VIDA
established a new CWA section 312(p) titled, ``Uniform National
Standards for Discharges Incidental to Normal Operation of Vessels.''
33 U.S.C. 1322(p). The VIDA consolidates and restructures the existing
regulatory framework applicable to incidental discharges of largely
commercial vessels 79 feet in length and above. The VIDA does not apply
to incidental discharges from vessels of the Armed Forces, recreational
vessels, and floating craft that are permanently moored to a pier.
Also, the VIDA does not apply to incidental discharges from small
vessels (less than 79 feet in length) or fishing vessels, except for
discharges of ballast water. The VIDA requires EPA to establish Federal
standards of performance for marine pollution control devices and the
USCG to establish corresponding implementing regulations to prevent or
reduce the incidental discharge of pollutants from vessels.
---------------------------------------------------------------------------
\1\ The Federal Water Pollution Control Act (FWPCA) is commonly
referred to as the CWA following the 1977 amendments to the FWPCA.
Public Law 95-217, 91 Stat. 1566 (1977). For ease of reference, the
agencies will generally refer to the FWPCA in this notice as the CWA
or the Act.
---------------------------------------------------------------------------
More specifically, the new CWA section 312(p)(4)(A)(i) directs the
EPA Administrator (``Administrator'') to develop Federal standards of
performance, in consultation with interested Governors and with the
concurrence of the Secretary of the department in which the USCG is
operating (``Secretary''). With limited exceptions, the VIDA requires
that the standards be at least as stringent as EPA's 2013 National
Pollutant Discharge Elimination System (NPDES) Vessel General Permit
(VGP) requirements established under CWA section 402. See 33 U.S.C.
1322(p)(4)(B)(iii) (EPA standards); id. (5)(A)(ii) (USCG requirements).
The VIDA also requires that the standards be technology-based using a
similar approach outlined by the CWA for setting, among other things,
effluent limitations guidelines. Id. (p)(4)(B)(i). The VIDA directs the
USCG to develop corresponding implementation, compliance, and
enforcement regulations within two years after EPA publishes the
Federal standards of performance. Id. (p)(5). The USCG implementing
regulations may also include requirements governing the design,
construction, testing, approval, installation, and use of devices to
achieve the EPA Federal standards of performance. Id. (p)(5)(B).
Existing requirements included in EPA's VGP, as well as the USCG's
existing requirements under section 110 of NANPCA, remain in place
until the new EPA and USCG regulations under CWA section 312(p) are
final, effective, and enforceable. Id. (p)(3). In addition, the VIDA
repealed the 2014 EPA NPDES Small Vessel General Permit (sVGP) and
established that neither EPA nor the states shall require an NPDES
permit for any discharge incidental to the normal operation of a
vessel, other than ballast water, from a small vessel or fishing
vessel, effective immediately upon the VIDA's enactment. Id.
(p)(9)(C)(i).
The final rule establishes both general and specific discharge
standards of performance for approximately 85,000 international and
domestic non-Armed Forces, non-recreational vessels operating in the
waters of the United States or the waters of the contiguous zone. The
types of vessels covered under the final rule include but are not
limited to public vessels of the United States, fishing vessels (for
ballast water discharges only), passenger vessels such as cruise ships
and ferries, barges, tugs and tows, offshore supply vessels, mobile
offshore drilling units, tankers, bulk carriers, cargo ships, container
ships, and research vessels. While most provisions are intended to
apply to a wide range of vessels, the VIDA specified that fishing
vessels would only be subject to ballast water provisions. Id.
(p)(2)(B)(i)(III). The requirements are based on, as applicable, best
available technology economically achievable, best conventional
pollutant control technology, and best practicable technology currently
available, including the use of best management practices (BMPs), to
prevent or reduce the discharge of pollutants into the waters of the
United States or the waters of the contiguous zone. Id. (p)(4)(B)(i)
and (ii).
The general discharge standards of performance apply to all vessels
and incidental discharges covered by the rule, as appropriate, and are
organized into three categories: (1) General Operation and Maintenance,
(2) Biofouling Management, and (3) Oil Management. 40 CFR 139.4 through
139.6. The general discharge standards of performance require BMPs to
minimize the introduction of pollutants from discharges.
The specific discharge standards of performance establish
requirements for discharges incidental to the normal operation of a
vessel from the following 20 distinct pieces of equipment and systems:
ballast tanks; bilges; boilers; cathodic protection; chain lockers;
decks; desalination and purification systems; elevator pits; exhaust
gas emission control systems; fire protection equipment; gas turbines;
graywater systems; hulls and associated niche areas; inert gas systems;
motor gasoline and compensating systems; non-oily machinery; pools and
spas; refrigeration and air conditioning; seawater piping; and sonar
domes. 40 CFR 139.10 through 139.29.
Pursuant to CWA section 312(p), the final discharge standards of
performance are at least as stringent as the VGP, with some exceptions
discussed below. 33 U.S.C.
[[Page 82076]]
1322(p)(4)(D)(ii). The final standards, however, do not incorporate the
VGP requirements verbatim. EPA is promulgating changes to the VGP
requirements to transition the permit requirements into regulations
that reflect national technology-based standards of performance, to
improve clarity, enhance enforceability and implementation, and/or to
incorporate new information and technology. In some cases, this results
in EPA consolidating or renaming the VGP requirements to comport with
the VIDA. The similarities and differences between the requirements in
the final discharge standards of performance and the requirements in
the VGP can be sorted into three distinct groups.
The first group consists of 13 discharge standards that are
substantially the same as the requirements of the VGP: boilers;
cathodic protection; chain lockers; decks; elevator pits; fire
protection equipment; gas turbines; inert gas systems; motor gasoline
and compensating systems; non-oily machinery; pools and spas;
refrigeration and air conditioning; and sonar domes. These 13 discharge
standards encompass the intent and stringency of the VGP but include
other changes to conform the requirements to the VIDA (e.g., extent of
regulated waters, consistency across discharge standards,
enforceability and legal precision, minor clarifications).
The second group consists of two discharge standards that are
consistent but slightly modified from the VGP to moderately increase
stringency or provide language clarifications: bilges and desalination
and purification systems.
The third group consists of five discharge standards that contain
the most significant modifications from the VGP: ballast tanks, exhaust
gas emission control systems, graywater systems, hulls and associated
niche areas, and seawater piping. In addition, the final rule modifies
slightly the VGP requirements as they apply in federally-protected
waters for five discharges: chain lockers, decks, hulls and associated
niche areas, pools and spas, and seawater piping. These modifications
address specific VIDA requirements as well as reflect new information
that has become available since the issuance of the VGP.
CWA section 312(p) also directs EPA to establish additional
discharge requirements for vessels operating in certain bodies of
water. See CWA section 312(p)(10(A) (Great Lakes); Id. (p)(10(C)
(Pacific Region); and Id. (p)(4)(B) (waters subject to Federal
protection, in whole or in part, for conservation purposes
(``federally-protected waters'')). These requirements further prevent
or reduce the discharge of pollutants into these waterbodies that may
contain unique ecosystems, support distinctive species of aquatic flora
and fauna, contend with more sensitive water quality issues, or
otherwise require greater protection.
Finally, as required under CWA section 312(p), the final rule
contains specific procedural requirements for states to petition EPA to
establish different discharge standards, issue emergency orders, or
establish a complete prohibition of one or more discharges into
specified State waters (``no-discharge zones''). 40 CFR 139.50 through
139.52.
II. Legal Authority
EPA promulgates this rule under CWA sections 301, 304, 307, 308,
312, and 501 as amended by the Vessel Incidental Discharge Act. 33
U.S.C. 1311, 1314, 1317, 1318, 1322, and 1361. This final rule fulfills
EPA's obligation under CWA section 312(p) to establish technology-based
Federal standards of performance for discharges incidental to the
normal operation of primarily non-Armed Forces, non-recreational
vessels 79 feet in length and above. This final rule also fulfills
EPA's consent decree obligation to sign (and promptly thereafter
transmit to the Office of Federal Register) a decision taking final
action following notice and comment rulemaking with regard to EPA's
October 26, 2020, proposed rule pertaining to Federal standards of
performance for marine pollution control devices for discharges
incidental to the normal operation of a vessel under CWA section
312(p)(4)(A)(i), 33 U.S.C. 1322(p)(4)(A)(i) (Vessel Incidental
Discharge National Standards of Performance, 85 FR 67818-01 (proposed
October 26, 2020)). (Consent Decree, Center for Biological Diversity,
et al. v. Regan, et al., Case No. 3:23-cv-535 (N.D. Cal. Dec. 13,
2023).
Under 33 U.S.C. 1369(b)(4)(A), any interested person may file a
petition for review of EPA's final agency action under 33 U.S.C.
1322(p). Any such petition may be filed only in the United States Court
of Appeals for the District of Columbia Circuit. 33 U.S.C.
1369(b)(4)(B).
III. Background
A. Clean Water Act
The CWA's regulatory regime to control vessel discharges has
changed over time. The first sentence of the CWA states, ``[t]he
objective of [the Act] is to restore and maintain the chemical,
physical, and biological integrity of the Nation's waters.'' 33 U.S.C.
1251(a). CWA section 301(a) provides that ``the discharge of any
pollutant by any person shall be unlawful'' unless the discharge is in
compliance with certain other sections of the Act. 33 U.S.C. 1311(a).
Among its provisions, the CWA authorizes EPA and other Federal agencies
to address the discharge of pollutants from vessels. As such, EPA
established regulations to address vessel discharges authorized under
CWA section 311 (addressing oil), section 312 (addressing sewage and
discharges incidental to the normal operation of a vessel of the Armed
Forces), and section 402 (pursuant to which EPA established the VGP).
From 1972 to 2005, EPA vessel regulations were primarily limited to
addressing the discharge of oil and sewage under CWA sections 311 and
312, respectively. In December of 2003, a long-standing exclusion of
discharges incidental to the normal operation of vessels from the CWA
section 402 NPDES permitting program became the subject of a lawsuit in
the U.S. District Court for the Northern District of California (Nw.
Envtl. Advocates v. EPA, No. C-03-05760-SI, 2005 WL 756614). The
lawsuit arose from EPA's September 2003 denial of a January 1999
rulemaking petition submitted to EPA by parties concerned about the
effects of ballast water discharges. Prior to the lawsuit, EPA, through
a 1973 regulation, had excluded discharges incidental to the normal
operation of vessels from the CWA section 402 permitting program. See
38 FR 13528, May 22, 1973. The petition asked the Agency to repeal its
regulation at 40 CFR 122.3(a) that excludes certain discharges
incidental to the normal operation of vessels from the requirement to
obtain an NPDES permit. The petition asserted that vessels are ``point
sources'' requiring NPDES permits for discharges to U.S. waters; that
EPA lacks authority to exclude point source discharges from vessels
from the NPDES program; that ballast water must be regulated under the
NPDES program because it contains invasive plant and animal species as
well as other materials of concern (e.g., oil, chipped paint, sediment,
and toxins in ballast water sediment); and that enactment of CWA
section 312(n) (the Uniform National Discharge Standards) in 1996
demonstrated Congress's rejection of the exclusion.
In March 2005, the court determined the exclusion exceeded the
Agency's authority under the CWA and subsequently declared in 2006 that
[[Page 82077]]
``[t]he blanket exemption for discharges incidental to the normal
operation of a vessel, contained in 40 CFR 122.3(a), shall be vacated
as of September 30, 2008.'' Nw. Envtl. Advocates v. EPA, C 03-05760 SI,
2006 WL 2669042, at *15 (N.D. Cal. Sept. 18, 2006), aff'd 537 F.3d 1006
(9th Cir. 2008). Shortly thereafter, Congress enacted two pieces of
legislation to exempt discharges incidental to the normal operation of
certain types of vessels from the requirement to obtain a permit. The
first of these, the Clean Boating Act of 2008 (Pub. L. 110-288, July
28, 2008), amended the CWA to provide that discharges incidental to the
normal operation of recreational vessels are not subject to NPDES
permitting, and created a new regulatory regime to be implemented by
EPA and the USCG under a new CWA section 312(o). The second piece of
legislation provided for a temporary moratorium on NPDES permitting for
discharges, excluding ballast water, subject to the 40 CFR 122.3(a)
exclusion from commercial fishing vessels (as defined in 46 U.S.C. 2101
and regardless of size) and those other non-recreational vessels less
than 79 feet in length. S. 3298, Public Law 110-299 (July 31, 2008).
In response to the court decision and the legislation, EPA issued
the first VGP in December 2008 for discharges incidental to the normal
operation of non-recreational, non-Armed Forces vessels 79 feet in
length and above. See 73 FR 79473, December 29, 2008. Additionally, in
September 2014, EPA issued the sVGP for discharges from non-
recreational, non-Armed Forces vessels less than 79 feet in length. See
79 FR 53702, September 10, 2014. Upon expiration of the 2008 permit,
EPA issued the second VGP in 2013. See 78 FR 21938, April 12, 2013.
After the EPA issuance of the VGP under the CWA and the USCG
promulgation of regulations under the NANPCA, the vessel community
expressed concerns regarding the lack of uniformity, duplication, and
confusion associated with the vessel regulatory regime. See Errata to
S. Rep. No. 115-89 (2019) (``VIDA Senate Report''), at 3-5 (discussing
these and similar concerns), available at https://www.congress.gov/115/crpt/srpt89/CRPT-115srpt89-ERRATA.pdf. In response, members of Congress
introduced various pieces of legislation to modify and clarify the
regulation and management of ballast water and other incidental vessel
discharges. In December 2018, President Trump signed into law the Frank
LoBiondo Coast Guard Authorization Act of 2018, which included the
VIDA. Public Law. 115-282, tit. IX (2018) (codified primarily at 33
U.S.C. 1322(p)). The VIDA restructures the way EPA and the USCG
regulate incidental vessel discharges from non-Armed Forces, non-
recreational vessels and amended CWA section 312 to include a new
subsection (p) titled, ``Uniform National Standards for Discharges
Incidental to Normal Operation of Vessels.'' CWA section 312(p), among
other things, immediately repealed EPA's 2014 sVGP and requires EPA and
the USCG to develop new regulations to replace the existing EPA VGP and
USCG vessel discharge requirements. See generally 33 U.S.C.
1322(p)(9)(C)(i) (repealing sVGP); id. (p)(4)(EPA's regulations); id.
(p)(5) (USCG's regulations). The VIDA also specifies that, effective
immediately upon enactment of the VIDA, neither EPA nor NPDES-
authorized states may require, or in any way modify, a permit under CWA
section 402 (NPDES) for any discharge incidental to the normal
operation of a vessel subject to regulation under section 312(p) or
from a small vessel (less than 79 feet in length) or fishing vessel (of
any size). Id. (p)(9)(C)(ii).
Specifically, CWA section 312(p)(4) directs the Administrator, with
concurrence of the Secretary \2\ and in consultation with interested
Governors, to promulgate Federal standards of performance for marine
pollution control devices for each type of discharge incidental to the
normal operation of non-recreational and non-Armed Forces vessels.\3\
CWA section 312(p)(5) also directs the Secretary to develop
corresponding implementing regulations to govern the implementation,
compliance, and enforcement of the Federal standards of performance.
Additionally, CWA section 312(p) generally preempts states from
establishing more stringent discharge standards once the USCG
implementing regulations required under CWA section 312(p)(5)(A)-(C)
are final, effective, and enforceable. Id. (p)(9)(A). The VIDA,
however, includes several exceptions to this expressed preemption (33
U.S.C. 1322(p)(9)(A)(ii)-(v); VIDA Senate Report, at 15 (discussing
these exceptions)) including a savings clause (33 U.S.C.
1322(p)(9)(A)(vi)) and provisions for states working directly with EPA
and/or the USCG to pursue additional requirements such as the
establishment of no-discharge zones for one or more incidental
discharges (33 U.S.C. 1322(p)(10)(D)). The VIDA also establishes
several programs to address invasive species, including the
establishment of the ``Great Lakes and Lake Champlain Invasive Species
Program'' research and development program and the ``Coastal Aquatic
Invasive Species Mitigation Grant Program.''
---------------------------------------------------------------------------
\2\ Concurrence procedures are governed by 33 U.S.C.
1322(p)(4)(A)(ii). Under those procedures, the Administrator must
submit to the Secretary a request for written concurrence with
respect to a proposed standard of performance. If the Secretary
fails to concur, it does not prevent the Administrator from
promulgating standard of performance, but does require the
Administrator to respond to the Secretary's written objections.
\3\ CWA section 312(b) provides authority for EPA to establish
Federal standards of performance for sewage from vessels within the
meaning of ``sewage'' as defined in section 312(a)(6). Thus, the
discharge of sewage from vessels, is not included in this CWA
section 312(p) rulemaking, except when commingled with other
discharges incidental to the normal operation of a vessel, as
authorized in CWA section 312(p)(2)(A)(ii). EPA and the USCG
regulate sewage from vessels under CWA section 312(b) as codified in
40 CFR part 140 (marine sanitation device standard) and 33 CFR part
159 subparts A through D (requirements for the design, construction,
certification, installation, and operation of marine sanitation
devices).
---------------------------------------------------------------------------
B. Additional U.S. and International Authorities
During the development of the final rule, EPA reviewed other U.S.
laws and international authorities that address discharges incidental
to the normal operation of a vessel. Where the requirements established
under these authorities are currently being met and implemented, EPA
generally considers them to be technologically available and
economically achievable as that term is used in the ``best available
technology economically achievable'' control level specified in CWA
section 301(b). As appropriate, EPA considered these requirements while
developing this final rule.
As expressly provided in the VIDA, this final rule will not affect
the requirements for vessels established under any other provision of
Federal law. 33 U.S.C. 1322(p)(9)(B). EPA provides a short summary of
these U.S. authorities, as well as some international authorities,
below.
International Convention for the Prevention of Pollution From Ships,
the Act To Prevent Pollution from Ships, and Implementing Regulations
The International Convention for the Prevention of Pollution from
Ships (MARPOL 73/78) is an international treaty that regulates certain
discharges from vessels. MARPOL Annexes regulate different types of
vessel pollution; the United States is a party to Annexes I, II, III,
V, and VI that address prevention/control of pollution from oil,
noxious liquid substances in bulk, harmful substances carried by sea in
packaged form, and garbage, and
[[Page 82078]]
prevention of air pollution, respectively. MARPOL is primarily
implemented in the United States by APPS, 33 U.S.C. 1901 et seq. The
USCG is the lead agency for APPS implementation and issued implementing
regulations primarily found at 33 CFR part 151. Those requirements
already apply to many of the vessels covered by the final rule.
APPS regulates the discharge of oil and oily mixtures, noxious
liquid substances, and garbage, including food wastes and plastic. With
respect to oil and oily mixtures, the USCG regulations at 33 CFR 151.10
prohibit ``any discharge of oil or oily mixtures into the sea from a
ship'' except when certain conditions are met. Exceptions include a
discharge oil content of less than 15 parts per million (ppm) and when
the ship operates oily water separating equipment, a bilge monitor, a
bilge alarm, or a combination thereof.
Substances regulated as noxious liquid substances under APPS are
divided into four categories based on their potential to harm marine
resources and human health. Under 46 CFR 153.1128, discharges of
noxious liquid substances residues at sea may only take place at least
12 nautical miles (NM) from the nearest land, among other requirements.
Because discharges at least 12 NM from the nearest land are outside the
geographic scope of the VIDA, the final rule does not affect the
requirements for vessels established under 46 CFR 153.1128 pursuant to
APPS.
MARPOL Annex III addresses harmful substances in packaged form and
is implemented in the United States by the Hazardous Materials
Transportation Authorization Act of 1994, as amended (49 U.S.C. 5901 et
seq.), and regulations appearing at 46 CFR part 148 and 49 CFR part
176. The regulatory provisions establish labeling, packaging, and
stowage requirements for such materials to help avoid accidental loss
or spillage during transport. The final rule does not regulate loss or
spillage of transported materials; however, the final rule establishes
BMPs to help reduce or prevent the loss of materials and debris
overboard.
Oil Pollution Act (33 U.S.C. 2701 et seq.)
The Oil Pollution Act of 1990 and the associated USCG implementing
regulations at 33 CFR parts 155 and 157 also address oil and oily
mixture discharges from vessels. These USCG regulations establish and
reinforce the 15 ppm discharge standard under APPS for oil and oily
mixtures for seagoing ships and require most vessels to have an oily
water separator. Oceangoing vessels of less than 400 gross tonnage (GT)
must either have an approved oily water separator or retain oily water
mixtures on board for disposal to an approved reception facility
onshore. Oceangoing vessels of 400 GT and above, but less than 10,000
GT, except vessels that carry ballast water in their fuel oil tanks,
must be fitted with ``approved 15 parts per million (ppm) oily-water
separating equipment for the processing of oily mixtures from bilges or
fuel oil tank ballast.'' 33 CFR 155.360(a)(1). Oceangoing ships of
10,000 gross tonnage and above and oceangoing ships of 400 gross
tonnage and above that carry ballast water in their fuel oil tanks,
must be fitted with approved 15 ppm oily water separating equipment for
the processing of oily mixtures from bilges or fuel oil tank ballast, a
bilge alarm, and a means for automatically stopping any discharge of
oily mixture when the oil content in the effluent exceeds 15 ppm. 33
CFR 155.370. 33 CFR part 155 also references oil containment and
cleanup equipment and procedures for preventing and reacting to oil
spills and discharges. The final rule is consistent with the existing
requirements for fuel and oil established under the Oil Pollution Act
and APPS and does not otherwise affect the requirements for vessels
established under these Acts.
Clean Water Act Section 311 (33 U.S.C. 1321)
CWA section 311, the Oil and Hazardous Substances Liability Act,
states that it is a policy of the United States that there should be no
discharges of oil or hazardous substances into the waters of the United
States, adjoining shorelines, and certain specified areas, except where
permitted under Federal regulations (e.g., the NPDES program). As such,
the Act prohibits the discharge of oil or hazardous substances into
these areas in such quantities as may be harmful. Further, the Act
states that the President shall, by regulation, determine those
quantities of oil and any hazardous substances that may be harmful if
discharged. EPA defines the discharge of oil in such quantities as may
be harmful as those that violate applicable water quality standards or
``cause a film or sheen upon or discoloration of the surface of the
water or adjoining shorelines or cause a sludge or emulsion to be
deposited beneath the surface of the water or upon adjoining
shorelines.'' 40 CFR 110.3. Sheen is clarified to mean ``an iridescent
appearance on the surface of the water.'' 40 CFR 110.1. The final rule
prohibits the discharge of oil, including oily mixtures, in such
quantities as may be harmful. 40 CFR 139.56(c).
Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. 136 et
seq.).
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
regulates the distribution, sale, and use of pesticides. One of the
primary components of FIFRA requires the registration and labeling of
all pesticides sold or distributed in the United States, ensuring that,
if pesticides are used in accordance with the specifications on the
label, they will not cause unreasonable adverse effects on humans or
the environment. The final rule reiterates the VGP requirement that any
registered pesticide must be used in accordance with its FIFRA label
for all activities that result in a discharge into the waters of the
United States or the waters of the contiguous zone. 40 CFR
139.4(b)(5)(iii). The final rule does not negate the requirements under
FIFRA and its implementing regulations to use registered pesticides
consistent with the product's labeling. In fact, the discharge of
pesticides used in violation of certain FIFRA requirements incorporated
into this rule is also a violation of these standards, and therefore a
violation of the CWA (e.g., exceeding hull coating application rates).
National Marine Sanctuaries Act (16 U.S.C. 1431 et seq. and
Implementing Regulations Found at 15 CFR Part 922 and 50 CFR Part 404)
The National Marine Sanctuaries Act (NMSA) authorizes the
designation and management of National Marine Sanctuaries to protect
marine resources with conservation, education, historical, scientific,
and other special qualities. Under NMSA, additional restrictions and
requirements may be imposed on vessel operators that operate in and
around National Marine Sanctuaries. Consistent with the VGP, the final
rule establishes additional restrictions and requirements for certain
discharges for vessels that operate in and around National Marine
Sanctuaries as these areas are included in the definition of
``federally-protected waters'' in the final rule and listed in appendix
A of part 139. Pursuant to CWA sections 312(p)(9)(B) and (E), discharge
requirements established by regulations promulgated by the Secretary of
Commerce under the National Marine Sanctuaries Act would continue to
apply to waters under the control of the Secretary of Commerce (e.g.,
National Marine Sanctuaries), in addition to the standards and
requirements established in this final rule.
[[Page 82079]]
C. Environmental Impacts of Discharges for Which Technology-Based
Discharge Standards Are Established by This Rule
While the VIDA requires EPA to establish technology-based
standards, which do not consider the effects on receiving water quality
(as discussed in greater detail in section VIII., Final Federal
Discharge Standards of Performance), EPA is presenting to the public
information about the following pollutants found in vessel discharges:
ANS, nutrients, pathogens, oil and grease, metals, toxic and
nonconventional pollutants with toxic effects, and other
nonconventional and conventional pollutants. Information regarding
water-quality impacts of these discharges and associated pollutants
were not considered in the development of Federal standards of
performance representing best available technology economically
achievable, as established in this rule. EPA presents this information
because the public may be interested in it and it informs the Economic
Analysis that characterizes the potential benefits associated with this
rule.
Discharges incidental to the normal operation of vessels can have
significant adverse impacts on aquatic ecosystems and other potential
impacts such as to human health through contamination of food from
aquaculture/shellfish harvesting areas through the addition of
pollutants. The adverse environmental impacts vary considerably based
on the type and number of vessels, the size and location of the port or
marina, and the condition of the receiving waters. These adverse
impacts are more likely to occur when there are significant numbers of
vessels operating in receiving waters with limited circulation or if
the receiving waters are already impaired. As a result of this
variation, protecting U.S. waters from vessel-related activities poses
unique challenges for local, State, and Federal Governments.
1. Aquatic Nuisance Species (ANS)
ANS, which can include invasive plants, animals, and pathogens, are
a persistent problem in U.S. coastal and inland waters. The VIDA
specifically includes ANS in the category of nonconventional pollutants
to be regulated through the application of best available technology
and best practicable technology. 33 U.S.C. 1322(p)(4)(B)(i).
ANS may be incidentally discharged or released from a vessel's
operations through a variety of vessel systems and equipment, including
but not limited to ballast water, sediment from ballast tanks, vessel
hulls and appendages, seawater piping, chain lockers, and anchor
chains. ANS pose severe threats to aquatic ecosystems, including
outcompeting native species, damaging habitat, changing food webs, and
altering the chemical and physical aquatic environment. Furthermore,
ANS can have profound and wide-ranging socioeconomic impacts, such as
damage to recreational and commercial fisheries, infrastructure, and
water-based recreation and tourism. Once established, it is extremely
challenging and costly to remove ANS and remediate the impacts. It has
become even more critical to control discharges of ANS from vessel
systems and equipment with the increase in vessel traffic due to
globalization and increased trade.
2. Nutrients
Nutrients, including nitrogen, phosphorus, and other micro-
nutrients, are constituents of incidental discharges from vessels.
Though often associated with discharges from sewage treatment
facilities and other sources such as runoff from agricultural and urban
stormwater sources, nutrients are also discharged from vessel sources
such as runoff from deck cleaning, graywater, and bilgewater.
Increased nutrient discharges from anthropogenic sources are a
major source of water quality degradation throughout the United States
(U.S. Geological Survey, 1999). Generally, nutrient over-enrichment of
waterbodies adversely impacts biological diversity, fisheries, and
coral reef and seagrass ecosystems (National Research Council, 2000).
One of the most notable effects of nutrient over-enrichment is the
excess proliferation of plant life and ensuing eutrophication. A
eutrophic system has reduced levels of dissolved oxygen and increased
turbidity which can lead to changes in the composition of aquatic flora
and fauna. Such conditions also fuel harmful algal blooms, which can
have significant adverse impacts on human health as well as aquatic
life (National Research Council, 2000; Woods Hole Oceanographic
Institute, 2007).
3. Pathogens
Pathogens-those bacteria, viruses, and other microorganisms that
can cause disease--can be found in discharges from vessels,
particularly in graywater and ballast water discharges. Discharges of
pathogens into waterbodies can adversely impact local ecosystems,
fisheries, and human health. Pathogens found in untreated graywater are
similar to, and in some cases may have a higher concentration than,
domestic sewage entering land-based wastewater treatment plants (U.S.
EPA, 2008; 2011d). Specific pathogens of concern found in graywater
include Salmonella spp., Escherichia coli, enteroviruses, hepatitis,
and pathogenic protists (National Research Council, 1993). Additional
pathogen discharges have also been associated with ballasting
operations, including Escherichia coli, intestinal enterococci, Vibrio
cholerae, Clostridium perfringens, Salmonella spp., Cryptosporidium
spp., Giardia spp., and a variety of viruses (Knight et al., 1999;
Reynolds et al., 1999; Zo et al., 1999). Pathogens can potentially be
transported in unfilled ballast water tanks (Johengen et al., 2005).
Under the VIDA, bacterial and viral pathogens can qualify as ``aquatic
nuisance species.'' 33 U.S.C. 1312(p)(1)(A), (Q), (R) (defining the
related terms ``aquatic nuisance species,'' ``nonindigenous species,''
and ``organism'').
4. Oil and Grease
Vessels can discharge a variety of oils during normal operations,
including lubricating oils, hydraulic oils, and vegetable or organic
oils. A significant portion of the lubricants discharged from a vessel
during these normal operations directly enters the aquatic environment.
Some types of oil and grease can be highly toxic and carcinogenic, and
have been shown to alter the immune system, reproductive abilities, and
liver functions of many aquatic organisms (Ober, 2010). Broadly, the
toxicity of oil and grease to aquatic life is due to reduced oxygen
transport potential and an inability of organisms to metabolize and
excrete oil and grease once ingested, absorbed, or inhaled.
The magnitude of impact of oils differs depending on the chemical
composition, method of exposure, concentration, and environmental
conditions (e.g., weather, salinity, temperature). It can therefore be
difficult to identify one single parameter responsible for negatively
impacting aquatic life.
Aromatic hydrocarbon compounds, commonly present in fuels,
lubricants, and additives, are consistently associated with acute
toxicity and harmful effects in aquatic biota (Dupuis and Ucan-Marin,
2015). Impacts are observed in both developing and adult organisms, and
include reduced growth, enlarged livers, fin erosion, reproduction
impairment, and modifications to heartbeat and respiration rates
(Dupuis and Ucan-Marin, 2015). Laboratory experiments have shown that
fish embryos exposed to hydrocarbons exemplify symptoms collectively
referred to as blue sac
[[Page 82080]]
disease. Symptoms of the disease range from reduced growth and spinal
abnormalities, to hemorrhages and mortality (Dupuis and Ucan-Marin,
2015). Oils can also taint organisms that are consumed by humans,
resulting in economic impacts to fisheries and potential human health
effects.
In establishing the final rule, EPA considered the availability of
environmentally acceptable lubricants (EALs). Production of EALs
focuses on using chemicals with oxygen atoms which increases their
water solubility and biodegradability, thereby decreasing their
accumulation in the aquatic environment. The solubility of EALs also
makes it easier for aquatic life to metabolize and excrete these
chemicals (U.S. EPA, 2011). Overall, EALs reduce the bioaccumulation
potential and toxic effects to aquatic life.
5. Metals
Vessel discharges can contain metal constituents from a variety of
onboard sources, including graywater, bilgewater, exhaust gas emission
control systems, and firemain systems. While some metals, including
copper, nickel, and zinc, are known to be essential to organism
function when present at certain levels, many others, including
mercury, lead, thallium, and arsenic, are non-essential and/or are
known to have only adverse impacts. Even essential metals may harm
organism function in sufficiently elevated concentrations. Some metals
may also bioaccumulate in the tissues of aquatic organisms,
intensifying toxic effects. Through a process called biomagnification,
concentrations of some metals can increase up the food chain, leading
to elevated levels in commercially harvested fish species (U.S. EPA,
2007). Exposure to metals through fish consumption or other exposure
pathways may have adverse human health effects (U.S. EPA, 2007). For
example, exposure to elevated levels of methylmercury is associated
with developmental and neurological effects, while exposure to lead is
known to cause a range of health effects, from behavioral problems and
learning disabilities to seizures and death (U.S. EPA, 2024 and 2024a).
Additionally, ingestion of arsenic may lead to increased risk of cancer
in the skin, liver, bladder, and lungs, as well as nausea, vomiting,
abnormal heart rhythm, and damage to blood vessels (Agency for Toxic
Substances and Disease Registry, 2007).
Vessel hulls and appendages are frequently coated in metal-based
biocides to prevent biofouling. The most widely-used metal in biocides
is copper. While it is an essential nutrient, copper can be both
acutely and chronically toxic to fish, aquatic invertebrates, and
aquatic plants at higher concentrations. Elevated concentrations of
copper can adversely impact survivorship, growth, and reproduction of
aquatic organisms (U.S. EPA, 2016). Copper can inhibit photosynthesis
in plants and interfere with enzyme function in both plants and animals
in concentrations as low as 4 micrograms ([micro]g)/L (U.S. EPA, 2016).
6. Other Pollutants
Vessel discharges can contain a variety of other toxic,
conventional, and nonconventional pollutants. This rule is intended to
prevent and control the discharge of certain pollutants that have been
identified in the various discharges. For example, graywater can
contain phthalates phenols, and chlorine (U.S. EPA, 2008). These
compounds can cause a variety of adverse impacts on aquatic organisms
and human health. Phthalates are known to interfere with reproductive
health, liver, and kidney function in both animals and humans.
(Sekizawa et al., 2003; DiGangi et al., 2002). Chlorine can cause
respiratory problems, hemorrhaging, and acute mortality to aquatic
organisms, even at relatively low concentrations (U.S. EPA, 2008).
Vessel discharges may also contain certain biocides used in vessel
coatings, which can be harmful to aquatic organisms. For example,
cybutryne, also commonly known as Irgarol 1051, is a biocide that
functions by inhibiting the electron transport mechanism in algae, thus
inhibiting growth. Numerous studies indicate that cybutryne is both
acutely and chronically toxic to a range of marine organisms, and in
certain cases, more harmful than tributyltin (Carbery et al, 2006; Van
Wezel and Van Vlaardingen, 2004).
Some vessel discharges are more acidic or basic than the receiving
waters, which can have a localized effect on pH (Alaska Department of
Environmental Conservation, 2007). For example, exhaust gas emission
control systems remove sulfur dioxide in exhaust gas and dissolve it in
washwater, where it is then ionized and produces an acidic washwater.
Research has shown that even minor changes in ambient pH can have
profound effects, such as developmental defects, reduced larval
survivorship, and decreased calcification of corals and shellfish (Oyen
et al., 1991; Zaniboni-Filho et al., 2009, Marubini and Atkinson,
1999).
IV. Scope of the Regulatory Action
A. Waters
The final rule applies to discharges into the waters of the United
States or the waters of the contiguous zone. 33 U.S.C. 1322(p)(8)(B).
Sections 502(7), 502(8), and 502(9) of the CWA define the terms
``navigable waters,'' ``territorial seas,'' and ``contiguous zone,''
respectively. 33 U.S.C. 1362(7)-(9). The term ``navigable waters''
means the waters of the United States including inland waters and the
territorial seas, where the United States includes the 50 States, the
District of Columbia, the Commonwealth of Puerto Rico, the U.S. Virgin
Islands, Guam, American Samoa, the Commonwealth of the Northern Mariana
Islands, and the Trust Territories of the Pacific Islands. Id. (7). The
term ``territorial seas'' means the belt of seas that extends three
miles seaward from the line of ordinary low water along the portion of
the coast in direct contact with the open sea and the line marking the
seaward limit of inland waters. Id. (8). For simplicity, EPA uses the
term ``shore'' to refer to the line of ordinary low water referenced in
the foregoing definition for ``territorial seas.'' The term
``contiguous zone'' means the entire zone established or to be
established by the United States under Article 24 of the Convention of
the Territorial Sea and the Contiguous Zone, which extends 12 NM under
Article 24 of the Convention of the Territorial Sea and the Contiguous
Zone. Id. (9).
B. Vessels
The final rule applies to discharges incidental to the normal
operation of any non-Armed Forces, non-recreational vessels as set
forth in CWA section 312(p)(2). The final rule does not apply to
discharges incidental to the normal operation of a vessel of the Armed
Forces subject to CWA section 312(n); a recreational vessel subject to
CWA section 312(o); a small vessel less than 79 feet in length or a
fishing vessel, except that the rule applies to any discharge of
ballast water from a small vessel less than 79 feet or fishing vessel;
or a floating craft that is permanently moored to a pier, including a
floating casino, hotel, restaurant, or bar. 33 U.S.C. 1322(p)(2)(B)(i).
The types of vessels covered under the final rule include but are not
limited to public vessels of the United States, commercial fishing
vessels (for ballast water only), passenger vessels (e.g., cruise ships
and ferries), barges, tugs and tows, offshore supply vessels, mobile
offshore drilling units, tankers, bulk carriers, cargo ships, container
ships, and research vessels.
[[Page 82081]]
The domestic and international vessel population that is subject to the
Federal standards of performance includes approximately 82,000 vessels.
The final rule also does not apply to a narrow category of specified
ballast water discharges that Congress believed do not pose a risk of
spreading or introducing ANS (33 U.S.C. 1322(p)(2)(B)(ii); VIDA Senate
Report, at 10), or to any discharges that result from (or contain
material derived from) an activity other than the normal operation of a
vessel (33 U.S.C. 1322(p)(2)(B)(iii)). Unless otherwise provided by CWA
section 312(p), any incidental discharges excluded from regulation in
the VIDA remain subject to the pre-enactment status quo (e.g., State
law, NPDES permitting, etc.). VIDA Senate Report, at 10.
The Federal standards of performance herein apply equally to new
and existing vessels except in such cases where the final rule
expressly distinguishes between such vessels, as authorized by CWA
section 312(p)(4)(C)(ii).
C. Incidental Discharges
The final rule establishes general and specific Federal standards
of performance for discharges incidental to the normal operation of a
vessel described in CWA section 312(p)(2). The general standards apply
to all vessels and all incidental discharges subject to regulation
under CWA section 312(p). The specific standards apply to specific
discharges incidental to the normal operation of the following types of
vessel equipment and systems: ballast tanks, bilges, boilers, cathodic
protection, chain lockers, decks, desalination and purification
systems, elevator pits, exhaust gas emission control systems, fire
protection equipment, gas turbines, graywater systems, hulls and
associated niche areas, inert gas systems, motor gasoline and
compensating systems, non-oily machinery, pools and spas, refrigerators
and air conditioners, seawater piping, and sonar domes.
D. Emergency and Safety Concerns
The VIDA recognizes that safety of life at sea and other emergency
situations not resulting from the negligence or malfeasance of the
vessel owner, operator, master, or person in charge may arise, and that
the prevention of loss of life or serious injury may require operations
that would not otherwise be consistent with these standards. Therefore,
no person would be found to be in violation of the final rule if they
qualify for the affirmative defense described in CWA section
312(p)(8)(C).
E. Effective Date
The effective date of this rule is 30 days after publication in the
Federal Register; however, the Federal standards of performance become
effective beginning on the date upon which the regulations promulgated
by the Secretary pursuant to CWA section 312(p)(5) governing the
implementation, compliance, and enforcement of the Federal standards of
performance become final, effective, and enforceable. Per CWA section
312(p)(3)(c), as of that date, the requirements of the VGP and all
regulations promulgated by the Secretary pursuant to Section 1101 of
the NANPCA (16 U.S.C. 4711) (as in effect on December 3, 2018),
including the regulations contained in subparts C and D of 33 CFR part
151 and 46 CFR 162.060 (as in effect on December 3, 2018), shall be
deemed repealed and have no force or effect. Similarly, as of that same
date, any CWA section 401 certification requirement in Part 6 of the
VGP, shall be deemed repealed and have no force or effect.
V. Stakeholder Engagement
During the development of the rule, EPA and the USCG engaged other
Federal agencies, States, Tribes, non-governmental organizations, the
general public, and the maritime industry. On October 26, 2020, EPA
published a Notice of Proposed Rulemaking (``proposed rule,'' 85 FR
67818) in the Federal Register for public comment. Following
publication of the proposed rule, EPA re-engaged with the states
through the VIDA's Governors consultation process to discuss topics for
which the states expressed an interest in further collaboration and
conducted post-proposal outreach to States, Tribes, and interested
stakeholders from environmental organizations and the regulated
community to obtain additional clarification regarding their concerns
with the proposed rule. Subsequently, on October 18, 2023, EPA
published in the Federal Register a Supplemental Notice of Proposed
Rulemaking (``supplemental notice,'' 88 FR 71788) for public comment
that presented ballast water management system (BWMS) type-approval
data that EPA received from the USCG since the proposed rule. The
supplemental notice also included additional regulatory options that
EPA was considering for discharges from ballast tanks, hulls and
associated niche areas, and graywater systems. General summaries of the
outreach are included in this section and in section XII., Statutory
and Executive Order Reviews. Detailed documentation is also available
in the docket.
A. Informational Webinars and Public Listening Sessions
EPA, in coordination with the USCG, hosted two informational
webinars on May 7 and 15, 2019 to enhance public awareness about the
VIDA and provide opportunity for engagement. During the webinars, EPA
and the USCG provided a general overview of the VIDA, discussed interim
and future discharge requirements, described future State and public
engagement opportunities, and answered clarifying questions raised by
the audience. The webinar recordings and presentation material are
available at https://www.epa.gov/vessels-marinas-and-ports/vessel-incidental-discharge-act-vida-engagement-opportunities.
Additionally, EPA, in coordination with the USCG, hosted a public,
in-person listening session at the U.S. Merchant Marine Academy in New
York on May 29-30, 2019. At the listening session, EPA, with the
support of the USCG, provided an overview of the VIDA, described the
interim requirements and the framework for the future regulations, and
conducted sessions on key vessel discharges to provide an opportunity
for public input. Fifty-two individuals from a variety of stakeholder
groups attended and provided input. Public input largely centered on
BWMSs, including testing methods and monitoring requirements.
Stakeholders requested harmonization of domestic regulations with those
of the International Maritime Organization (IMO), such as standards for
exhaust gas emission control systems. Input was also received on
challenges with compliance and reporting under the VGP and the USCG
ballast water regulations. The meeting agenda and a summary of the
comments received are available in the docket.
During the public comment period for both the proposed rule and
supplemental notice, EPA held public meetings to describe procedures
for submitting comments on the rule and provide an opportunity for
stakeholders to ask clarifying questions. Details and materials from
these public meetings are available at https://www.epa.gov/vessels-marinas-and-ports/vessel-incidental-discharge-act-vida-stakeholder-engagement-opportunities.
B. Consultation and Coordination With States
1. Federalism Consultation and Governors Consultation
As noted in the proposed rule, EPA concluded that this action has
[[Page 82082]]
federalism implications pursuant to the terms of Executive Order 13132.
As such, EPA consulted with State and local officials early in the
development of this rule. On July 9, 2019, in Washington, DC, EPA and
the USCG conducted a Federalism consultation briefing to allow states
and local officials to have meaningful and timely input into EPA's
rulemaking for the development of the Federal standards of performance.
Additional information regarding the VIDA Federalism Consultation can
be found in section XII. Statutory and Executive Order Reviews.
In addition, CWA section 312(p)(4)(A)(iii)(II) directs EPA to
develop a process for soliciting input from interested Governors to
inform the development of the Federal standards of performance,
including sharing information relevant to the process. On July 10 and
18, 2019, EPA and the USCG, with the support and assistance of the
National Governors Association, held meetings with Governors'
representatives to provide an overview of the VIDA, discuss State
authorities under the VIDA, and solicit input on a process that would
meet both the statutory requirements and State needs. Based on this
input, EPA developed a process to obtain Governors' input on the
rulemaking. Thirteen states (Alaska, California, Hawaii, Maryland,
Michigan, Minnesota, New York, North Carolina, Ohio, Puerto Rico,
Virginia, Washington, and Wisconsin) participated in the process, as
did representatives from the Western Governors Association, the Pacific
States Marine Fisheries Commission, and the All Islands Coral Reef
Committee.
To obtain Governors' input, EPA hosted three regional, web-based
forums for Governors and their representatives to inform EPA early in
the development of the proposed rule on the challenges and concerns
associated with existing requirements under the VGP and to discuss
potential considerations for key discharges of interest. The forums
were held in 2019 on September 10 for West Coast states, September 12
for Great Lakes states, and September 19 for all states. During each
forum, subject-matter experts from EPA provided a brief background on
the VIDA followed by organized discussions regarding the key discharges
identified by the regional representatives prior to the forum. During
the organized discussions, interested Governors' representatives
commented on the presentation content, shared applicable scientific or
technical information, and provided suggestions for EPA to consider
during the development of the Federal standards of performance. In
addition to the verbal input provided during the forums, EPA accepted
written comments. Copies of those written comments are included in the
docket.
On December 18, 2019, EPA held two follow-up calls with
representatives from the Great Lakes states. During each call, EPA
addressed the comments that had been submitted by the Great Lakes
states, including comments on specific requirements of the VIDA, non-
ballast water discharges, and best available technology as it relates
to BWMSs. Representatives from Illinois, Michigan, Minnesota, New York,
Ohio, Pennsylvania, and Wisconsin attended the calls.
EPA also held a follow-up call with representatives from the West
Coast states on January 15, 2020. During the call, EPA addressed the
comments that had been submitted by West Coast states, including
comments on outreach and engagement, the best available technology
analysis for BWMSs, and regulation of biofouling and in-water cleaning
and capture devices. Representatives from California, Hawaii, Oregon,
and Washington, as well as representatives from the Pacific States
Marine Fisheries Commission and the Western Governors Association,
attended the call.
After the public comment period concluded for the proposed rule,
EPA met with State representatives to discuss topics of interest
between June and October 2021 to inform the supplemental notice.
During the engagement with states, EPA received pre-proposal
comments, as well as post-proposal comments on the proposed rule and
supplemental notice, from states, Governors, and Governors'
representatives. Comments were received from representatives from
Alabama, Alaska, American Samoa, California, the Commonwealth of the
Northern Mariana Islands, Connecticut, Delaware, Florida, Guam, Hawaii,
Illinois, Louisiana, Maine, Maryland, Massachusetts, Michigan,
Minnesota, Mississippi, New Hampshire, New Jersey, New York, North
Carolina, Ohio, Oregon, Pennsylvania, Puerto Rico, Rhode Island, U.S.
Virgin Islands, Virginia, Washington, Wisconsin, and the Western
Governors Association. Comments on the proposed rule primarily focused
on ballast water, biofouling, and the State engagement process, while
comments on the supplemental notice focused on EPA's analysis of newly
obtained ballast water data and the additional regulatory options
presented for ballast tanks, hulls and associated niche areas, and
graywater systems. These comments can be found in the docket.
2. Governor Objections
In conjunction with the requirement to engage states in the
development of the proposed standards, CWA section
312(p)(4)(A)(iii)(III) provides an avenue for Governors to formally
object to a proposed Federal standard of performance. An interested
Governor may submit to the Administrator a written, detailed objection
to the proposed Federal standard of performance, describing the
scientific, technical, and operational factors that form the basis of
the objection. Before finalizing a Federal standard of performance for
which there has been an objection from one or more interested
Governors, the CWA requires the Administrator to provide a written
response to the objection detailing the scientific, technical, or
operational factors that form the basis for that standard.
EPA received five objection letters from the Governors of
California, Hawaii, Michigan, Minnesota, and Washington. One or more of
these states objected to aspects of the proposed Federal standard of
performance for ballast tanks, biofouling management, chain lockers,
decks, exhaust gas emission control systems, fire protection equipment,
graywater systems, hulls and associated niche areas, and procedures for
states to request changes to standards, regulations, or policy
promulgated by the Administrator. In the objection letters, Governors
also raised concerns outside of the scope of specific Federal standards
of performance, such as the timing and substance of State consultation
and purported inconsistency with State water quality standards. EPA
addressed specific comments and concerns raised by these five states in
the relevant topical sections of the Comment Response Document
available in the docket. Consistent with the CWA, the Administrator
responded to these Governors in writing prior to the publication of
this final rule.
VI. Public Comments Received and Agency Responses
EPA received 28,701 comments on the proposed rule and 45,820
comments on the supplemental notice for a total of 74,521 comments
received. Of these, 292 comments were unique, while the remaining
comments were received from participants in mass mailer campaigns. The
majority of comments addressed proposed requirements for specific
discharges, though comments also contained feedback on general
[[Page 82083]]
topics of concern, such as stakeholder engagement. EPA fully considered
comments and, where appropriate, made changes to the final rule to
reflect comments received. The sections below describe those changes to
the final rule and a comprehensive Comment Response Document is
available in the docket.
VII. Definitions
The final rule includes definitions for several statutory,
regulatory, and technical terms. 40 CFR 139.2. These definitions apply
solely for the purposes of this final rule and do not affect the
definitions of any similar terms used in any other context. Where
possible, EPA relied on existing definitions from other laws,
regulations, and the VGP to provide consistency with existing
requirements. Many of the definitions are taken either verbatim or with
minor clarifying edits from the VIDA, the legislation which this final
rule implements. This includes definitions for: aquatic nuisance
species (ANS), ballast water, ballast water exchange, ballast water
management system (BWMS), Captain of the Port (COTP) Zone, commercial
vessel--as that term is used for vessels operating within the Pacific
Region, empty ballast tank, Great Lakes State, internal waters, live or
living, marine pollution control device, organism, Pacific Region, port
or place of destination, render nonviable, saltwater flush, Secretary,
small vessel or fishing vessel (and the term ``fishing vessel'' to
direct the reader to the definition of ``small vessel or fishing
vessel''), and VGP.
EPA included definitions from other sections of the CWA, USCG
regulations, the VGP, and other regulations, as well as new definitions
specific to this final rule. EPA modified some of the definitions in
the proposed rule based on public comments. Terms not defined in the
final rule have the meaning defined under the CWA and applicable
regulations.
Definitions for the following terms were added to provide clarity
and ensure that the associated regulations are understood by the
regulated community: active discharge of biofouling, anti-fouling
coating, anti-fouling system, ferry, fire protection equipment, in-
water cleaning with capture (IWCC), in-water cleaning without capture,
macrofouling, marine inspector, microfouling, new ferry, passenger
vessel, passive discharge of biofouling, and seawater piping system
(See also the comment response sections for 40 CFR 139.21, Graywater
systems, 40 CFR 139.22, Hulls and associated niche areas, 40 CFR
139.28, Seawater piping, and 40 CFR 139.19, Fire protection equipment).
In response to public comments, the final rule slightly revises the
definitions of ``macrofouling'' and ``microfouling'' from the
definitions presented in the supplemental notice to provide additional
clarity and consistency. It also dispenses with the use of the Navy
Fouling Rating scale in favor of the terms macrofouling and
microfouling (See also the comment response for 40 CFR 139.28, Seawater
piping).
Several definitions were modified from the proposed rule. The
definition for ``Marine Growth Prevention System (MGPS)'' now
references the added definition for ``seawater piping system,'' while
EPA modified the definition for ``niche areas'' to add clarity and
remove language that would be confusing within the context of the VIDA
(See also the comment response section for 40 CFR 139.22, Hulls and
associated niche areas). In response to concerns raised by commenters,
the definition for ``organism'' was modified to replace the word
``means'' with ``includes,'' consistent with the CWA definition.
Definitions for ``oil-to-sea interface,'' ``EAL,'' and ``reception
facility'' were modified slightly to provide additional clarity for the
regulated community (See also the comment response section for 40 CFR
139.6, Oil management). ``Captain of the Port Zone'' now includes
references to other United States Code for additional clarity and
consistency (See also the comment response for Subpart A--Scope). The
definition for ``midocean'' was modified slightly to maintain
consistency within the final rule (See also the comment response
section for 40 CFR 139.10, Ballast tanks). Finally, EPA removed the
definition for ``scheduled drydocking'' as that term is not used in the
final rule.
VIII. Final Federal Discharge Standards of Performance
In adopting CWA section 312(p)(4)(B)(i), Congress directed EPA to
promulgate Federal standards of performance for conventional
pollutants, toxic pollutants, and nonconventional pollutants (including
ANS). The VIDA cross-references existing statutory standards in the CWA
at sections 301 and 304 of the CWA (as well as EPA's implementing
regulations at 40 CFR 125.3), which indicates that Congress intended
for EPA to base the VIDA standards of performance on the same statutory
considerations as those applicable when setting technology-based
effluent limits for permits under CWA section 402.\4\ The provisions
cited in the VIDA (CWA sections 301(b) and 304, 33 U.S.C. 1311(b) and
1314), are the basis for EPA's development of effluent limitations
guidelines, which are national performance-based requirements
established by regulation for categories of point sources based on
degree of control that can be achieved using various levels of
pollution control technology, as specified in the CWA. Thus, many of
the same legal standards and considerations that apply to the
development of technology-based effluent limitation guidelines also
apply to the development of the VIDA's Federal standards of
performance.
---------------------------------------------------------------------------
\4\ The VIDA does not reference CWA section 306 for new source
standards, meaning that the CWA ``best available demonstrated
control technology'' standard does not apply to new sources
regulated by the VIDA.
---------------------------------------------------------------------------
The CWA and its legislative history of CWA sections 301(b) and
304(b) (33 U.S.C. 1311(b) and 1314(b)), describe the need to press
toward higher levels of control through research and development of new
processes, modifications, replacement of obsolete plants and processes,
and other improvements in technology, taking into account the cost of
controls to ``require elimination of pollutant discharges . . . if the
Administrator finds, on the basis of information available to him, . .
. that such elimination is technologically and economically achievable
for a category or class of point sources as determined in accordance
with regulations issued by the Administrator . . .''. 33 U.S.C.
1311(b)(2)(A). The legislative history and case law also support that
EPA does not consider water quality impacts on individual water bodies
as technology-based standards are developed (Statement of Senator
Muskie, October 4, 1972, reprinted in A Legislative History of the
Water Pollution Control Act Amendments of 1972, at 170. (U.S. Senate,
Committee on Public Works, Serial No. 93-1, January 1973); Southwestern
Elec. Power Co. v. EPA, 920 F.3d at 1005, ``The Administrator must
require industry, regardless of a discharge's effect on water quality,
to employ defined levels of technology to meet effluent limitations.''
(citations and internal quotations omitted).
The CWA establishes a two-step process for implementation of
increasingly stringent technology-based effluent limitations. The first
step requires compliance with standards based on``the application ofthe
best practicable control technology currently available [BPT] as
defined by the Administrator . . .'' 33 U.S.C. 1311(b)(1)(A). The
second step requires
[[Page 82084]]
compliance with standards based on application of the ``best available
technology economically achievable [BAT] for such category or class . .
.'' 33 U.S.C. 1311(b)(2)(A). The CWA, as amended in 1977, replaced the
BAT standard with a new standard, ``best conventional pollutant control
technology [BCT],'' but only for certain ``conventional pollutants''
(i.e., BOD, TSS, oil and grease, fecal coliform, and pH). See 33 U.S.C.
1311(b)(2)(E) and 1314(a)(4) and 40 CFR 401.16.
The CWA requires consideration of BPT for conventional, toxic, and
nonconventional pollutants. CWA section 304(a)(4) designates the
following as conventional pollutants: BOD, TSS, fecal coliform, and pH,
and any additional pollutants defined by the Administrator as
conventional. The Administrator designated oil and grease as an
additional conventional pollutant on July 30, 1979. 40 CFR 401.16.
Toxic pollutants (e.g., toxic metals such as arsenic, mercury,
selenium, and chromium; toxic organic pollutants such as benzene,
benzo-a-pyrene, phenol, and naphthalene) are those outlined in CWA
section 307(a) and subsequently identified in EPA regulations at 40 CFR
401.15 and 40 CFR part 423 appendix A. All other pollutants are
nonconventional, including aquatic nuisance species. (33 U.S.C.
1322(p)(4)(B)(i)(III)).
In determining BPT, under CWA sections 301(b)(1)(A) and
304(b)(1)(B), and 40 CFR 125.3(d)(1), EPA evaluates several factors.
EPA first considers the cost of application of currently available
technology in relation to the effluent reduction benefits.
Traditionally, as is consistent with the statute, its legislative
history, and caselaw, EPA defines ``currently available'' based on the
average of the best performance of facilities within the industry,
grouped to reflect various ages, sizes, processes, or other common
characteristics (Chem. Mfrs. Assn. v. EPA, 870 F.2d 177, 207-208 (5th
Cir. 1989)). The Agency also considers the age of equipment and
facilities, the processes employed, engineering aspects of various
types of control techniques, process changes, non-water quality
environmental impacts (including energy requirements), and such other
factors as the Administrator deems appropriate. If, however, existing
performance is uniformly inadequate within an industrial category, EPA
may establish limitations based on higher levels of control if the
Agency determines that the technology is available in another category
or subcategory and can be practically applied to this industrial
category.
The 1977 amendments to the CWA required EPA to identify effluent
reduction levels for conventional pollutants associated with BCT for
discharges from existing industrial point sources. 33 U.S.C.
1311(b)(2)(E); 1314(b)(4)(B); 40 CFR 125.3(d)(2). In addition to
considering the other factors specified in CWA section 304(b)(4)(B) to
establish BCT requirements, EPA also considers a two-part ``cost-
reasonableness'' test. EPA explained its methodology for the
development of BCT requirements in 1986. See 51 FR 24974, July 9, 1986.
For toxic pollutants and nonconventional pollutants, EPA
promulgates discharge standards based on BAT. 33 U.S.C. 1311(b)(2)(A)
and 1314(b)(2)(B); 40 CFR 125.3(d)(3). In establishing BAT, the
technology must be technologically ``available'' and ``economically
achievable.'' The factors considered in assessing BAT include the cost
of achieving BAT effluent reductions, the age of equipment and
facilities involved, the process employed, potential process changes,
non-water quality environmental impacts, including energy requirements,
and other such factors as the Administrator deems appropriate. EPA
retains considerable discretion in assigning the weight accorded to
these factors. See Weyerhaeuser Co v. Costle, 590 F.2d 1011, 1045 (D.C.
Cir. 1978). EPA usually determines economic achievability on the basis
of costs of compliance with BAT limitations on overall industry and
subcategory financial conditions. BAT discharge standards may be based
on effluent reductions attainable through changes in a facility's
processes and operations. BAT reflects the highest performance in the
industry and may reflect a higher level of performance than is
currently being achieved based on technology transferred from a
different subcategory or category. Southwestern Elec. Power Co. v. EPA,
920 F.3d at 1006; Am. Paper Inst. v. Train, 543 F.2d 328, 353 (D.C.
Cir. 1976); Am. Frozen Food Inst. v. Train, 539 F.2d 107, 132 (D.C.
Cir. 1976). BAT may be based upon process changes or internal controls,
even when these technologies are not common industry practice. See
American Frozen Foods, 539 F.2d 107, 132, 140 (D.C. Cir. 1976).
CWA section 312(p)(4)(B)(ii) is also modelled off of established
CWA concepts and directs EPA to use BMPs in certain circumstances. See,
e.g., VIDA Senate Report at 11 (``As with the technology standards
themselves, this best management practice language is modeled off a
similar regulatory provision for NPDES permits to ensure that the
Administrator applies the same relevant considerations under section
312(p).''). Specifically, CWA section 312(p)(4)(B)(ii) requires
employing BMPs to control or abate any discharge incidental to the
normal operation of a vessel if: (1) numeric discharge standard
standards are infeasible; or (2) or if the BMPs are reasonably
necessary to achieve the standards or to carry out the purpose of
reducing and eliminating the discharge of pollutants.
Where EPA did not impose a numeric standard,\5\ EPA determined that
they were infeasible. For these discharges, the particular challenges
posed by setting standards for moving vessels at sea made numeric
standards impracticable. For example, many of the specific discharge
streams (e.g. chain lockers) would be impossible to monitor using
available technology without putting the safety of crew members at
risk. The physical nature of other discharge streams (e.g. deck
runoff), which differs significantly from the normal contexts for which
EPA normally imposes CWA numerical discharge standards, also makes
setting a numeric standard impracticable. EPA also did not receive
comments indicating that it was practicable to impose numeric standards
for any specific discharges for which it required BMPs in the final
rule. EPA received several comments supporting EPA's use of BMPs.
---------------------------------------------------------------------------
\5\ General operation and maintenance (section139.4), biofouling
management (section 139.5), oil management (section 139.6), boilers
(section 139.12), cathodic protection (section 139.13), chain
lockers (section 139.14), decks (section 139.15), desalination and
purification systems (section 139.16), elevator pits (section
139.17), fire protection equipment (section 139.19), gas turbines
(section 139.20), hull and associated niche areas (section 139.22),
inert gas systems (section 139.23), motor gasoline and compensating
systems (section 139.24), non-oily machinery (section 139.25),
refrigeration and air conditioning (section 139.27), seawater piping
(section 139.28), sonar domes (section 139.29).
---------------------------------------------------------------------------
Additionally, EPA determined for certain discharges where it was
practicable to impose numerical discharge standards that additional
BMPs for these specific discharges are reasonably necessary to carry
out the purpose and intent of CWA section 312(p).\6\ For example, while
EPA set numeric discharge standards for ballast tanks at 40 CFR
139.10(d), the Agency also required best management practices at 40 CFR
139.10(c) that are important for reducing discharges of ANS and thus
are reasonably necessary to achieve the numeric discharge standards for
ballast
[[Page 82085]]
tanks. BMPs consist of specific and implementable practices that will
drive the reduction of pollutant discharges from vessels. BMPs rely on
existing available technologies and will lead to reductions in
pollutant discharges even given the highly variable nature of
incidental discharges from vessels and practical difficulties in
monitoring those discharges. Additionally, requiring the BMPs for those
same specific discharges that were subject to BMPs under the VGP is
consistent with the VIDA's requirement that existing VGP requirements
serve as a regulatory baseline.
---------------------------------------------------------------------------
\6\ Ballast tanks (section 139.10), bilges (139.11), exhaust gas
emission control systems (section 139.18), graywater systems
(section 139.21), pools and spas (section 139.26).
---------------------------------------------------------------------------
CWA section 312(p)(4)(B) also establishes minimum requirements for
the Federal standards of performance such that, ``the combination of
any equipment or best management practice . . . shall not be less
stringent than'' the effluent limits and related requirements
established in Parts 2.1, 2.2, or 5 of the VGP. 33 U.S.C.
1322(p)(4)(B)(iii). Thus, while the CWA directs EPA to set the Federal
standards of performance at the level of BPT/BCT/BAT, depending on the
pollutant, it also creates a presumption that those standards would
provide protection at least equivalent to the VGP requirements. There
are exceptions at CWA section 312(p)(4)(D)(ii)(II) for situations where
either new information becomes available that ``would have justified
the application of a less-stringent standard'' or ``if the
Administrator determines that a material technical mistake or
misinterpretation of law occurred when promulgating the existing
standard.'' Absent one of those exceptions, the statute directs that
EPA ``shall not revise a standard of performance . . . to be less
stringent than an applicable existing requirement.'' 33 U.S.C.
312(p)(4)(D)(ii)(I).
EPA endeavored to identify instances where the BPT/BCT/BAT level of
control called for new, more stringent regulation than under the VGP
for the VIDA Federal standards of performance. Where EPA research
identified new alternatives or new options for marine pollution control
devices, EPA evaluated those options as candidates for new BPT/BCT/BAT
requirements. Where EPA identified no such new information or options,
EPA continues to rely on the BPT/BCT/BAT analysis that led to the
development of the VGP requirements. Additionally, EPA has considered
in its BPT/BCT/BAT analysis that VGP requirements are currently in
effect and are being achieved by regulated parties. This approach is
consistent with EPA's obligations under CWA section 312(p)(4) because
the effluent limits that EPA adopted in the VGP were already the
product of a BPT/BCT/BAT analysis described in the permit fact sheets
for both the 2008 and 2013 iterations of the VGP and corresponding
supporting materials. CWA section 312(p)(4)(D)(ii) prohibits EPA from
``revis[ing] a standard of performance . . . to be less stringent than
an applicable existing requirement'' except for the narrow exception
identified in the previous paragraph. Absent such exception, the VIDA
prohibits EPA from identifying a less stringent option as BPT/BCT/BAT.
Indeed, by identifying the VGP as the minimum requirements for the
Federal standards of performance and then expressly identifying the
circumstances under which EPA could select a different, less stringent
standard (i.e., new information or error), the text and legislative
history of the VIDA show that Congress intended to preserve, in most
instances, the existing VGP requirements as a regulatory floor. VIDA
Senate Report, at 12 (``The exceptions to this provision [for new
information and technical or legal error] would provide the sole basis
for the Administrator to weaken standards of performance compared to
the legacy VGP requirements . . . .''). Moreover, Congress did not
intend for EPA to depart from the considerations that informed the
VGP's technology-based effluent limits. To the contrary, although the
VIDA created a rule-based framework, rather than a permitting
framework, Congress defined BPT, BCT, and BAT with ``intentional[ ]
cross-reference[s]'' to terms used elsewhere in the CWA ``to ensure
that the Administrator makes identical considerations when setting the
standards of performance under CWA section 312(p) as the Administrator
was previously required to do when setting technology-based effluent
limits for permits'' as was done in the VGP. VIDA Senate Report, at 11.
While EPA is, for most of the discharges addressed in this
rulemaking, relying on the BPT/BCT/BAT analysis that was performed to
develop the VGP and the fact that certain discharge requirements are
already currently in effect under the VGP, EPA did not incorporate the
VGP requirements verbatim. In many cases, EPA translated the VGP
discharge requirements into Federal standards of performance or
otherwise improved the clarity to enhance implementation and
enforceability. As such changes do not materially differ from the
requirements established in the VGP, EPA reasonably relied on the BPT/
BCT/BAT analysis that supported the VGP to develop the final Federal
standards of performance.
In some instances, EPA updated language from the proposed rule to
the final rule from ``including'' to ``including but not limited to''
to make absolutely clear that a list may be representative but not
exhaustive and/or to ensure that language is not overly narrow or
restrictive so as to preclude the use of new technologies or BMPs in
the future that otherwise comply with the applicable requirements. As
an example, 40 CFR 139.13(a) was updated to clarify that a vessel's
cathodic corrosion protection device includes, but is not necessarily
limited to, sacrificial anodes and impressed current cathodic
protection systems. See 40 CFR 139.13(a) (``The requirements in
paragraph (b) of this section apply to discharges resulting from a
vessel's cathodic corrosion control protection device, including but
not limited to sacrificial anodes and impressed current cathodic
protection systems.'') (emphasis added). The final rule also uses the
more commonly recognized abbreviation ``GT,'' rather than ``GT ITC'' as
used in the proposed rule, to mean the same thing. This modification is
intended to align the language with existing regulations and the IMO.
Additionally, EPA determined that two of the VGP-named discharges
do not require specific discharge requirements beyond the general
discharge requirements detailed in subpart B and special area
requirements in subpart D. Discharges from motor gasoline and
compensating systems and inert gas systems are discharges incidental to
the normal operation of a vessel. However, EPA determined that the
requirements outlined in the general discharge standards in subpart B
for both discharges, and the special area requirements in subpart D for
motor gasoline and compensating systems, constitute BAT and are at
least as stringent as the VGP.
Many of the comments EPA received asserted that the proposed rule
would not adequately protect water quality in a particular region or
jurisdiction. Notwithstanding that the VIDA requires EPA's Federal
standards of performance to carry forward certain VGP requirements, the
VGP requirements and the VIDA Federal standards of performance are
subject to different legal frameworks for considering water quality
impacts. The VGP was an NPDES permit under which discharges had to meet
both technology-based levels of control (See CWA sections 301(b) and
304(b), 33 U.S.C. 1311(b) and 1314(b)) and any more stringent controls
as necessary to protect water quality
[[Page 82086]]
(See CWA section 301(b)(1)(C); 33 U.S.C. 1311(b)(1)(C)), as well as any
requirements of a State certification under CWA section 401 (33 U.S.C.
1341). The VIDA, by contrast, directs EPA to establish the Federal
standards of performance solely on a technology basis. This is evident
from the VIDA's text, which references the CWA provisions governing
technology-based rules and does not reference the CWA provisions
calling for more stringent limitations to protect water quality or
State certifications under CWA section 401. Additionally, the VIDA's
text makes clear that EPA and authorized states may not issue NPDES
permits to VIDA-regulated discharges, further indicating that NPDES
permitting elements such as water quality-based effluent limitations
and certifications under section 401 do not apply. See 33 U.S.C.
1322(p)(9)(C)(ii).
The VGP, like all CWA section 402 permits, needed to account for
the potential impact of discharges on the quality of the receiving
waters. The VGP did so in two ways, and neither are applicable to the
VIDA Federal standards of performance. First, the CWA section 402 and
NPDES regulations at 40 CFR 122.44(d) require permits to include more
stringent water quality based effluent limits (WQBELs) when technology-
based effluent limits (TBELs) are not sufficient to meet applicable
water quality standards. The VGP included WQBELs at Part 2.3. Second,
CWA section 401(d) allows States and Tribes to condition permits on
``any effluent limitations and other limitations, and monitoring
requirements'' necessary to assure compliance with water quality
requirements, including State water quality standards. Pursuant to this
authority, the VGP included a number of specific requirements for
individual states or Indian Country lands at Part 6. While the VIDA
directed EPA to preserve certain VGP requirements (specifically, those
at Parts 2.1, 2.2, and 5) in the Federal standards of performance, it
did not preserve the WQBELs at Part 2.3 or the specific individual
states' and Indian Country Lands' requirements at Part 6.
In contrast to permits issued under CWA section 402, technology-
based effluent limitations developed under CWA sections 301(b) and
304(b) do not account for the quality of the receiving waters,
including any water quality standards that may apply. See Southwestern
Elec. Power Co. v. EPA, 920 F.3d 999, 1005 (5th Cir. 2019) (``The Act
requires ELGs [developed under CWA section 304(b)] to be based on
technological feasibility rather than on water quality'') (citing E.I.
du Pont de Nemours & Co. v. Train, 430 U.S. 112, 130-31 (1977)); See
also Weyerhaeuser Co. v. Costle, 590 F.2d 1011, 1042 (D.C. Cir. 1978)
(discussing Congress's decision in adopting the CWA to base national
standards on technology rather than receiving water quality).
Therefore, Congress intended EPA to establish the requirements of this
regulation based on the performance of technologies without regard to
effects on receiving water quality, after a consideration of the
factors specified in CWA section 304(b), 33 U.S.C. 1314(b).
Rather than incorporate water quality-based considerations into the
Federal standards of performance, Congress instead chose to have EPA,
the USCG, and states address location-specific water quality impacts
through different approaches. For example, CWA section 312(p)(4)(E)
authorizes EPA, in concurrence with the USCG and in consultation with
states, to ``require, by order, the use of an emergency best management
practice for any region or category of vessels'' where such an order
``is necessary to reduce the reasonably foreseeable risk of
introduction or establishment of an aquatic nuisance species'' or
``will mitigate the adverse effects of a discharge that contributes to
a violation of a water quality [standard].'' Elsewhere in the statute,
CWA section 312(p)(10)(D) creates a process to create geographically
bound no-discharge zones to ``protect and enhance the quality of the
specified waters.''
The final rule contains discharge standards that correspond to
required levels of technology-based control (BPT, BCT, BAT) for
discharges incidental to the normal operation of a vessel, as required
by the CWA. In assessing the availability and achievability of the
technologies discussed herein, in addition to the rationale for the VGP
effluent limits, EPA considered studies and data from both domestic and
international sources including studies and data from foreign-flagged
vessels, as appropriate. As noted above, some discharge standards
considered other existing laws and requirements (e.g., Oil Pollution
Act, APPS, and the Clean Hull Act). Where these laws already exist, EPA
includes appropriate practices pursuant to these laws as part of the
final standards to the extent these are demonstrated practices that EPA
finds to be the best practicable control technology currently available
(BPT) and best available technology economically achievable (BAT). For
example, the final standards reaffirm requirements of the Clean Hull
Act that coating on vessel hulls must not contain tributyltin or any
other organotin compound used as a biocide.
A. Discharges Incidental to the Normal Operation of a Vessel--General
Standards
This section describes the Federal standards of performance
associated with the general discharge requirements in 40 CFR part 139,
subpart B. These standards are designed to apply to all vessels and
incidental discharges subject to the final rule to the extent the
requirements are appropriate for each incidental discharge. These
standards are proactive and preventative in nature and are designed to
minimize the introduction of pollutants into the waters of the United
States and the waters of the contiguous zone. The standards are based
on EPA's analysis of available and relevant information, including
available technical data, existing statutes and regulations,
statistical industry information, and research studies included in the
docket.
1. General Operation and Maintenance
The first category of Federal standards of performance are
requirements associated with general operation and maintenance
practices that are designed to eliminate or reduce the discharge of
pollutants from vessels. 40 CFR 139.4. Unless otherwise noted, changes
from the proposed rule are based on public comments EPA received on the
proposed rule. The general operation and maintenance standards contain
an overarching requirement that all discharges subject to this rule
must be minimized. In a change from the proposed rule intended to
provide greater clarity, the final rule specifies that a vessel
operator must minimize discharges through management practices
including, but not limited to, storage onboard the vessel, proper
storage or transfer of materials, or reduced production of discharge.
40 CFR 139.4(b)(1). These requirements are ``best management
practices'' (BMPs) under the CWA; which are defined under CWA section
312(p)(1)(H) as a schedule of activities, prohibitions of practices,
maintenance procedures, and other management practices to prevent or
reduce the pollution of the waters of the United States or the waters
of the contiguous zone. Further, the term ``best management practice''
includes any treatment requirement, operating procedure, or practice to
control vessel runoff, spillage or leaks, sludge or waste disposal, or
drainage from raw material storage. According to the VIDA, the
Administrator shall require the use of best management practices to
control or abate any discharge if numeric
[[Page 82087]]
standards of performance are infeasible; or the best management
practices are reasonably necessary to achieve the standards of
performance; or to carry out the purpose and intent of this subsection.
EPA determined that these BMPs are necessary because it is infeasible
to identify a single numeric standard where: (1) operation and
maintenance requirements usually are not expressed numerically; and (2)
even if they could be expressed numerically, there is not a numeric
operation and maintenance standard that would be appropriate to apply
to the multitude vessels, discharge streams, and pollutants subject to
the VIDA. Id. (p)(4)(B)(ii). The final rule defines the term
``minimize'' to mean ``to reduce or eliminate to the extent achievable
using any control measure that is technologically available and
economically practicable and achievable and supported by demonstrated
BMPs such that compliance can be documented in shipboard logs and
plans,'' which will be determined by the Secretary. Minimizing
discharges provides a reasonable approach for vessels to reduce all the
incidental discharges subject to this rule, including for discharges
not subject to specific discharge standards. Minimization of some
discharges, such as graywater, may be achieved through simple practices
like reduced production, while other discharges, such as ballast water,
may require more complex practices, such as saltwater flush or ballast
water exchange. To further carry out the purpose and intent of the
VIDA, the final rule at 40 CFR 139.4(b)(2) requires vessels to
discharge while underway and as far from shore, as practicable. Id.
(p)(4)(B)(ii).
The final general operation and management standards also limit the
types and quantities of materials that a regulated vessel may
discharge. 40 CFR 139.4(b)(3) prohibits the addition of any materials
to a discharge, other than for treatment of the discharge, that is not
incidental to the normal operation of the vessel. 40 CFR 139.4(b)(4)
prohibits using dilution to meet any effluent discharge standards.
While EPA recognizes some vessel systems use water permissibly under
the rule, for example to generate chlorine for disinfection, such a
practice may not be used as a means of dilution for purposes of meeting
the discharge standard. 40 CFR 139.4(b)(5) specifies requirements for
any materials used onboard that may subsequently be discharged (e.g.,
disinfectants, cleaners, biocides, coatings, sacrificial anodes). The
final rule specifies that materials used onboard that may subsequently
be discharged must be used only in the amount necessary to perform its
intended function, and also, in response to public comment, that
materials must be used according to manufacturer specifications. 40 CFR
139.4(b)(5)(i). The final rule also prohibits the discharge of any
material used onboard that will be subsequently discharged that
contains any materials banned for use in the United States. 40 CFR
139.4(b)(5)(ii). For any pesticide products (e.g., biocides, anti-
microbials) subject to FIFRA registration, vessel operators must follow
the FIFRA label for all activities that result in a discharge into the
waters of the United States or the waters of the contiguous zone. 40
CFR 139.4(b)(5)(iii).
To prevent materials and associated pollutants from being washed
overboard, the rule requires that vessel operators minimize any
exposure of cargo or other onboard materials that may be inadvertently
discharged by containerizing or covering materials. 40 CFR 139.4(b)(6).
Several commenters requested clarification about the effect of this
regulation on hopper barge operations and expressed concern about
potential safety impacts. In a change from the proposed rule, the final
rule at 40 CFR 139.4(b)(6) exempts hopper barges without a fixed cover
or in circumstances when a vessel operator reasonably determines
compliance with this requirement would interfere with essential vessel
operations, negatively impact safety of the vessel, risk loss of life
at sea, or violate any applicable regulations that establish
specifications for safe transportation, handling, carriage, and storage
of toxic or hazardous materials.
The presence or use of toxic or hazardous materials may be
necessary for the operation of vessels. For purposes of the final rule,
the term ``toxic or hazardous materials'' is defined at 40 CFR 139.2 to
mean any toxic pollutant identified in 40 CFR 401.15 or any hazardous
material as defined in 49 CFR 171.8. To minimize and prevent discharges
of toxic or hazardous materials, the final rule requires toxic or
hazardous material containers to be appropriately sealed, labeled, and
secured, and located in an area of the vessel that minimizes exposure
to ocean spray and precipitation consistent with vessel design, unless
the master determines this would interfere with essential vessel
operations or safety of the vessel or crew, or would violate any
applicable regulations that establish specifications for safe
transportation, handling, carriage, and storage of toxic or hazardous
materials. 40 CFR 139.4(b)(7)(i). Also, to avoid discharges and prevent
emergency or other dangerous situations, the final rule requires that
containers holding toxic or hazardous materials not be overfilled and
incompatible materials not be mixed. 40 CFR 139.4(b)(7)(ii). In
response to confusion from a commenter, the final rule includes
additional language not included in the proposed rule to clarify that
incompatible materials are substances which, if mixed, will create
hazards greater than that posed by the individual substances (See the
comment response section for 40 CFR 139.4, General operation and
maintenance). Id. Wastes should be managed in accordance with any
applicable local, State, and Federal regulations, which are outside of
the scope of this final rule. For example, the Resource Conservation
and Recovery Act (RCRA) governs the generation, transportation,
storage, and disposal of solid and hazardous wastes.
Like the requirements related to toxic and hazardous materials, the
final standard at 40 CFR 139.4(b)(8) prohibits the discharge or
disposal of containers holding toxic or hazardous materials. 40 CFR
139.4(b)(9) requires that vessel operators clean out compartments,
including tanks, cargo, or other spaces, to meet the definition of
``broom clean'' or equivalent prior to washing such areas. Further, the
final rule at 40 CFR 139.4(b)(10) requires vessel operators to maintain
their topside surface (i.e., exposed decks, hulls above waterline,
tank, cargo, and related appurtenances) to minimize the discharge of
cleaning compounds, paint chips, non-skid material fragments, and other
materials associated with exterior topside surface preservation. 40 CFR
139.4(b)(11) requires that painting and coating techniques on topside
surfaces minimize the discharge of paints, coatings, surface
preparation materials, and similar substances, and 40 CFR 139.4(b)(12)
prohibits the discharge of any unused paints and coatings.
The final general operation and maintenance requirement
consolidates requirements from multiple sections of the VGP and
specifies that any equipment that may release, drip, leak, or spill oil
or oily mixtures, fuel, or other toxic or hazardous materials,
including to the bilge, must be maintained regularly to minimize or
eliminate the discharges. 40 CFR 139.4(b)(13).
2. Biofouling Management
Vessel biofouling is the accumulation of aquatic organisms such as
plants,
[[Page 82088]]
animals, and microorganisms on vessel equipment or systems immersed in
or exposed to the aquatic environment. Biofouling discharges include
but are not limited to those from maintenance and cleaning activities
of hulls, niche areas, and associated coatings. Biofouling can include
pathogens, as well as microscopic fouling (``microfouling'') and
macroscopic fouling (``macrofouling''). Microfouling is biofouling
caused by bacteria, fungi, microalgae, protozoans, and other
microscopic organisms that creates a biofilm, also called a slime
layer. Microfouling is a precursor to macrofouling. Macrofouling is
biofouling caused by the attachment and subsequent growth of visible
plants and animals. Macrofouling includes large, distinct,
multicellular individual or colonial organisms visible to the human
eye, such as barnacles, tubeworms, mussels, fronds/filaments of algae,
bryozoans, sea squirts, and other large attached, encrusting, or mobile
organisms.
Biofouling on vessel equipment and systems is one of the main
vectors for the introduction and spread of aquatic nuisance species
(ANS) (Gollasch, 2002; Drake and Lodge, 2007; Hewitt et al., 2009;
Hewitt and Campbell, 2010). Biofouling organisms are discharged from
vessel surfaces both passively through sloughing and actively through
in-water cleaning activities (See 40 CFR 139.2, definitions of
``passive discharge of biofouling'' and ``active discharge of
biofouling''). Biofouling produces drag on a vessel hull and protruding
niche areas, leading to greater fuel consumption and increased
greenhouse gas emissions. It can also result in hull corrosion and
blockage of internal seawater piping, such as the engine cooling and
firemain systems, thereby degrading the integrity of the vessel
structure and impeding safe operation.
In the proposed rule, EPA included requirements to reduce the
discharge of biofouling organisms from vessel equipment and systems,
notably from hulls and associated niche areas, by requiring vessel
operators to develop and follow a biofouling management plan and follow
specific in-water equipment and system cleaning protocols.
Additionally, EPA proposed to prohibit in-water cleaning of biofouling
on hulls and associated niche areas that exceed a U.S. Navy fouling
rating (FR) of FR-20, except when the fouling is local in origin and
cleaning does not result in the substantial removal of a biocidal anti-
fouling coating, as indicated by a plume or cloud of paint; or, when an
in-water cleaning and capture (IWCC) system is used that is designed
and operated to capture coatings and biofouling organisms, filter
biofouling organisms from the effluent, and minimize the release of
biocides. EPA recommended, but did not propose to require, the use of
IWCC systems for removal of local macrofouling.
Based on comments received during the public comment period for the
proposed rule and subsequent meetings with interested States, Tribes,
and other stakeholders held between August and November 2021, EPA
published a supplemental notice that discussed additional regulatory
options for discharges from hulls and associated niche areas. The
supplemental notice discussed five key issues raised during the public
comment period for the proposed rule regarding the general
applicability of the hull and associated niche area requirements and
cleaning of this equipment as proposed in 40 CFR 139.22(a) and (d). All
comments were considered in preparation of the final rule.
EPA in the VGP considered discharges of biofouling organisms to be
incidental when such discharges originate from vessel equipment and
systems while the vessel is immersed in or exposed to the aquatic
environment. Both the VGP and the discharge regulations promulgated
pursuant to CWA section 312(n) for incidental discharges from vessels
of the Armed Forces included management requirements to minimize the
discharge of biofouling organisms from vessel equipment and systems.
The VGP in Parts 2.2.23 and 4.1.3 required that vessel operators (1)
minimize the transport of attached living organisms; and (2) conduct
annual inspections of the vessel hull (including niche areas) for
fouling organisms, respectively. Part 4.1.4 of the VGP also required
vessel operators to prepare drydock inspection reports to demonstrate
that the vessel hull and other surface and niche areas had been
inspected for attached living organisms and that those organisms had
been removed or neutralized. These reports were to be made available to
EPA or an authorized representative of EPA upon request. Except in
those circumstances specified in CWA section 312(p)(4)(D)(ii)(II),
EPA's discharge regulations must be as stringent as those in the VGP.
The final rule includes these requirements for the discharge of
biofouling organisms from vessel equipment and systems.
Among the comments EPA considered were ones suggesting that
biofouling should not be regulated as a discharge incidental to the
normal operation of a vessel under the VIDA. However, EPA continues to
interpret the statutory definition of ``discharge incidental to the
normal operation of a vessel'' (``incidental discharge'') at CWA
section 312(a)(12) to include discharges of biofouling organisms from
vessel equipment and systems. As described in the proposed rule and
supplemental notice, biofouling discharges are an ordinary accompanying
circumstance of vessel operation and transit and thus fit the plain
meaning of ``discharge incidental to the normal operation of a
vessel.'' (85 FR 67818, October 26, 2020, section VIII.A.2 and 88 FR
71788, October 18, 2023, section IV.C.1). Additionally, the definition
of ``discharge incidental to the normal operation of a vessel''
explicitly uses the word ``including,'' indicating that although
``biofouling'' is not specifically mentioned in the definition, the
definition's list of discharges is illustrative and not exhaustive. 33
U.S.C. 1322(a)(12). Other enumerated terms within the definition also
reasonably encompass biofouling. For example, ``any other pollutant
discharge from the operation of a marine propulsion system, shipboard
maneuvering system, crew habitability system, or installed major
equipment. . .'' encompasses biofouling discharge from a vessel hull
because the shipboard maneuvering systems cannot ``operate'' without
the hull. Id. Additionally, ``a discharge in connection with the . . .
maintenance[ ] and repair'' of any ``protective, preservative, or
absorptive application to the hull'' could include biofouling
discharge. Id. Finally, the statutory history and regulatory history
support EPA's interpretation, particularly because the VGP regulated
the same types of biofouling discharges as the final rule.
The final rule requires each vessel to develop a biofouling
management plan to minimize the discharge of biofouling organisms,
thereby minimizing the potential for the introduction and spread of
ANS. 40 CFR 139.5(b). The requirement to develop a biofouling
management plan is intended to provide a holistic strategy that
considers the operational profile of the vessel, identifies the
appropriate anti-fouling systems, and details the biofouling management
practices for specific areas of the vessel. The details of the plan
would fall under the USCG's implementing regulations established under
CWA section 312(p)(5), although the plan elements must prioritize
procedures and strategies to prevent macrofouling.
While the VGP did not explicitly require a biofouling management
plan,
[[Page 82089]]
it required the majority of the components that EPA expects will
comprise a biofouling management plan individually, such as: (1) the
consideration of vessel class, operations, and biocide release rates
and components in the selection of anti-fouling systems; (2) an annual
inspection of the vessel hull and niche areas for assessment of
biofouling organisms and condition of anti-fouling paint; (3) a drydock
inspection report noting that the vessel hull and niche areas have been
inspected for biofouling organisms and those organisms have been
removed or neutralized; (4) reporting of cleaning schedules and
methods; and (5) appropriate disposal of wastes generated during
cleaning operations. Additionally, per the Clean Hull Act of 2009,
every vessel engaging in one or more international voyages is required
to carry an anti-fouling system certificate that contains the details
of the anti-fouling system (See 33 U.S.C. 3821). Moreover, under
regulations promulgated under the authority of the National Invasive
Species Act, the USCG has required the individual in charge of any
vessel equipped with ballast water tanks that operates in the waters of
the United States to maintain a ballast water management plan that has
been developed specifically for the vessel and that will allow those
responsible for the plan's implementation to understand the vessel's
ballast water management strategy and comply with the requirements. 33
CFR 151.2050. That ballast water management plan is to include detailed
biofouling maintenance and sediment removal procedures (33 CFR
151.2050(g)(3)). Consistent with guidance issued by the USCG on those
regulations, these procedures were to be incorporated into the ballast
water management plan or included as separate Biofouling Management and
Sediment Management Plans and referenced in the ballast water
management plan (USCG, 2014). Under this guidance, the USCG advised
that IMO Resolution Marine Environment Protection Committee (MEPC)
207(62) provides effective guidance for developing and implementing a
vessel-specific biofouling management plan.
Developing vessel-specific biofouling management plans is important
because vessels can vary widely in operational profile and, therefore,
in the extent and type of biofouling. However, the final rule
recognizes that vessels with similar operational profiles, such as
vessels that cross the same waterbodies, travel at similar speeds, and
share the same design, may also employ the same management measures,
such as selecting the same types of anti-fouling systems and applying
the same inspection and cleaning schedules. It is anticipated that
fleet owners may develop a biofouling management plan template that can
be readily adapted into a vessel-specific biofouling management plan.
To address comments received on the proposed rule, the final rule
clarifies that a biofouling management plan must be developed to
minimize the discharge of biofouling organisms, prioritize procedures
and strategies to prevent macrofouling (thereby minimizing the
potential for the introduction and spread of ANS), and describe the
vessel-specific anti-fouling systems and biofouling management
practices necessary to comply with requirements in 40 CFR 139.5. The
USCG, through its regulations developed under CWA section 312(p)(5),
has the authority to specify the details of the plan, including how
vessel operators are to implement and follow that plan. The final rule
also references 40 CFR 139.13 (cathodic protection), 139.14 (chain
lockers), 139.22 (hulls and associated niche areas), 139.28 (seawater
piping), and 139.29 (sonar domes) for additional biofouling management
requirements.
3. Oil Management
The final rule aims to minimize discharges of oil, including oily
mixtures, and requires vessel operators to use control and response
measures to prevent, minimize, and contain spills and overflows during
fueling, maintenance, and other vessel operations. 40 CFR 139.6(d).
This reinforces existing requirements found at 33 CFR part 155 that
require taking immediate and appropriate corrective actions if an oil
spill is observed because of vessel operations, including maintaining
appropriate spill containment and cleanup materials onboard and
immediately using such materials in the event of any spill.
Also, the final rule specifies that the discharge of used or spent
oil no longer being used for its intended purpose is prohibited. 40 CFR
139.6(b). This includes any used or spent oil that may be added to an
incidental discharge that is otherwise authorized to be discharged.
Overall, this section authorizes discharges of small amounts of oil,
including oily mixtures, incidental to the normal operation of a vessel
provided such discharges comply with the otherwise applicable existing
legal requirements. For example, consistent with the CWA, this standard
prohibits the discharge of oil in such quantities as may be harmful, as
defined in 40 CFR 110.3. See 40 CFR 139.6(c) (prohibiting discharges in
quantities that may be harmful) and 139.2 (defining ``Discharge of oil
in such quantities as may be harmful'' by reference to 40 CFR 110.3 and
110.5).
The final rule at 40 CFR 139.3 specifies that, except as expressly
provided, nothing in this part affects the applicability of any other
provision of Federal law as specified in several statutory and
regulatory citations. 40 CFR 139.3 includes citations for CWA section
311 and the Act to Prevent Pollution from Ships (APPS) (33 U.S.C. 1901
et seq.), both of which address discharges of oil. Under CWA section
311, any oil, including oily mixtures, other than those exempted in 40
CFR 110.5, may not be discharged in such quantities as ``may be
harmful,'' which is defined to include those discharges that violate
applicable water quality standards or ``cause a film or sheen upon or
discoloration of the surface of the water or adjoining shorelines or
cause a sludge or emulsion to be deposited beneath the surface of the
water or upon adjoining shorelines.'' Discharges that are not included
in the description of ``may be harmful'' include discharges of oil from
a properly functioning vessel engine (including an engine on a public
vessel) and any discharges of such oil accumulated in the bilges of a
vessel discharged in compliance with 33 CFR part 151 subpart A; other
discharges of oil permitted under MARPOL 73/78, Annex I, as provided in
33 CFR part 151 subpart A; and any discharge of oil explicitly
permitted by the Administrator in connection with research,
demonstration projects, or studies relating to the prevention, control,
or abatement of oil pollution. The United States enacted the APPS to
implement the nation's obligations under MARPOL 73/78. As the lead
agency for APPS implementation, the USCG issued implementing
regulations primarily found at 33 CFR part 151. Those APPS requirements
already apply to many of the vessels that are covered by this rule.
Among other things, the APPS regulates the discharge of oil and oily
mixtures. Generally, these requirements prohibit ``any discharge of oil
or oily mixtures into the sea from a ship'' except when certain
conditions are met, including a discharge with an oil content of less
than 15 ppm and that the ship operates oily-water separating equipment,
an oil content monitor, a bilge alarm, or a combination thereof.
The final rule also includes requirements for oil-to-sea
interfaces. Specifically, the final rule requires the use of
environmentally acceptable lubricants (EALs) for oil-to-sea
[[Page 82090]]
interfaces unless technically infeasible. 40 CFR 139.6(e). The final
standard for general operation and maintenance at 40 CFR 139.4 also
identifies a series of mandatory BMPs for minimizing lubricant
discharges during maintenance.
Oil-to-sea interfaces are defined as seals or surfaces on shipboard
equipment where the design is such that small quantities of oil can
escape into the surrounding waters during normal vessel operations. See
40 CFR 139.2. For example, below-water seals frequently use lubricating
oil mechanisms that maintain higher pressure than the surrounding sea
to ensure that no seawater enters the system and compromises the unit's
performance. Above-deck equipment with portions of the machinery
extended overboard, or equipment mounted to the exterior hull of the
vessel, may also have oil-to-sea interfaces. During normal operation,
small quantities of lubricant oil in these interfaces are discharged
directly into surrounding waters. Constituents of conventional
hydraulic and lubricating oils vary by manufacturer, but may include
copper, tin, aluminum, nickel, and lead. In addition, traditional
mineral oils have a low biodegradation rate, a high potential for
bioaccumulation, and a measurable toxicity towards marine organisms.
Vessels use lubricants in a wide variety of shipboard applications.
Examples of lubricated equipment with oil-to-sea interfaces include:
Stern tube: A stern tube is the casing or hole through the
hull of the vessel that enables the propeller shaft to connect the
vessel's engine to the propeller on the exterior of the vessel. Stern
tubes contain seals designed to keep the stern tube lubricant from
exiting the equipment array and being discharged to waters at the
exterior of the vessel's hull.
Controllable pitch propeller: Variably pitched propeller
blades are for changing the speed or direction of a vessel and
supplementing the main propulsion system. Controllable pitch propellers
also contain seals that prevent the lubricant from exiting the
equipment array.
Rudder bearings: These bearings allow a vessel's rudder to
turn freely; they also use seals with an oil-to-sea interface.
Lubricated deck equipment above the water surface line
that extends overboard: Hose handling cranes, hydraulic system
provision handling cranes, hydraulic cranes, and hydraulic stern ramps
are examples of machinery with the potential for above-water discharges
of lubricants. When vessels are underway, this equipment is often not
operational, and any lubricant losses are typically captured during
deck washdown and treated as part of deck washdown wastewater. However,
discharges can occur when portions of the machinery such as booms or
jibs, trolleys, cables, hoist gear, or derrick arms are in use and
extend over the side of vessel.
Lubricated equipment, such as accommodation ladders,
mounted to the exterior of the vessel hull.
In the case of controllable pitch propellers (CPP), up to 20 ounces
of hydraulic and lubricating oils could be released for every CPP blade
that is replaced, with blade replacement occurring at drydock intervals
or when the blade is damaged. When the blade replacement includes
removal of the blade port cover (generally occurring infrequently, less
than once per month), up to five gallons of oil could be discharged
into surrounding waters unless the service is performed in drydock.
Additionally, many oceangoing vessels operate with oil-lubricated stern
tubes. Oil leakage from stern tubes, once considered a part of normal
``operational consumption'' of oil, has become an issue of global
concern and is now treated as oil pollution. A 2001 study commissioned
by the European Commission DG Joint Research Centre concluded that
routine unauthorized operational discharges of oil from ships into the
Mediterranean Sea created more pollution than accidental spills
(Pavlakis et al., 2001). Similarly, an analysis of data on oil
consumption sourced from a lubricant supplier indicated that daily
stern tube lubricant consumption rates for different vessels could
range up to 20 liters per day (Etkin, 2010). This analysis estimated
that operational discharges (including stern tube leakage) from vessels
add between 36.9 million liters and 61 million liters of lubricating
oil into marine port waters annually.
One commenter requested that EPA restore language from the VGP
recommending use of seawater-based systems for stern tube lubrication
to eliminate the discharge of oil from these interfaces to the aquatic
environment. EPA agrees, and the Agency has added this VGP language
back into the text of the final standard. See 40 CFR 139.6(e)
(``Operators of new build vessels should endeavor to use seawater-based
systems for stern tube lubrication to eliminate the discharge of oil
from these interfaces to the aquatic environment.'')
The final rule at 40 CFR 139.2 defines an EAL as a lubricant or
hydraulic fluid, including any oil or grease, that is
``biodegradable,'' ``minimally-toxic,'' and ``not bioaccumulative.''
The addition of ``or hydraulic fluid'' to the definition clarifies,
consistent with VGP implementation, that any hydraulic fluid containing
oils or greases and used in equipment with an oil-to-sea interface
requires use of an EAL, unless technically infeasible. Based on several
comments received regarding oil-to-sea interfaces on deck equipment,
EPA reexamined the definition for ``oil-to-sea interface'' at 40 CFR
139.2 and updated it to clarify that oil-to-sea interfaces are found on
equipment subject to immersion as well as equipment above the surface
line that extends overboard or is mounted to the exterior of the hull.
This modification is in line with EPA's regulation of those portions of
vessel deck equipment from which lubricant or hydraulic fluid losses
cannot otherwise be managed onboard the vessel.
More than 16 manufacturers have produced EALs for the global
shipping community, providing vessel operators with a wide array of
choices for optimizing lubricant technical performance. Most major
marine equipment manufacturers have approved EALs for use in their
machinery, and new equipment, such as air seals, is being introduced
and refined commercially to minimize or eliminate the need for EALs.
The market for EALs continues to expand around the world, particularly
in Europe where the use of such lubricants is promoted through a
combination of tax breaks, purchasing subsidies, and national and
international labeling programs. Thus, EAL's are widely available to
vessels in the marketplace and their use. And while vessels must incur
additional costs to purchase EALs, EPA has analyzed those costs in its
Economic Analysis and finds them to be economically achievable. The
Agency has thus determined that product substitution of EALs for other
lubricants in oil-to-sea applications (unless technically infeasible),
together with the required BMPs for maintenance, represents BAT for
discharges from oil-to-sea interfaces. Use of EALs in lieu of
conventional formulations for oil-to-sea interfaces can offer
significantly reduced discharges of pollutants of concern (U.S. EPA,
2011).
As part of the BAT analysis for the VGP, EPA considered the
processes employed and potential process changes that might be
necessary for vessels to use EALs. As EPA explained at the time, EALs
are readily available, and their use is economically achievable for
applications where it is technologically available (U.S. EPA, 2011).
The 40 CFR 139.6(e) requirement carries forward
[[Page 82091]]
EPA's VGP approach based on BAT that numeric standards of performance
for discharges from oil-to-sea interfaces are infeasible but that EALs
are technologically available, economically achievable, and reasonably
necessary to carry out the purpose and intent of this subsection. New
vessels can select equipment during design and construction that is
compatible with EALs. Furthermore, vessel operators can design
additional onboard storage capacity for EALs if they choose to use
traditional mineral-based oil for engine lubrication (thereby needing
two types of oils on-hand). The extra storage capacity needed would be
minor. However, EPA considers the use of EALs in some applications to
not be technologically practicable or achievable, such as for when
there is existing equipment for which no compatible products are
currently available. Therefore, the final rule at 40 CFR 139.6(e)
retains the caveat from the VGP that EALs must be used in oil-to-sea
interfaces except when ``technically infeasible.''
The Agency considered several other approaches for regulating oil-
to-sea interfaces. For one, the most recent version of the European
Ecolabel program has a modified definition of what constitutes an EAL
in that it now allows for ``small quantities'' (i.e., <0.1 percent) of
bioaccumulative substances in lubricant formulations. EPA considered
revising the definition of ``biodegradable'' at 40 CFR 139.2 to more
closely align the terminology with current European Ecolabel
requirements for achieving specific levels of degradation within 10,
rather than 28, days. EPA notes that stakeholders involved in the
European Ecolabel program felt strongly that this change in the test
pass window would significantly reduce the number of lubricant
formulations available on the market. To ensure widespread installation
and use of EALs by vessels that operate in the waters of the United
States or the waters of the contiguous zone, EPA in 40 CFR 139.2
retained the definition of ``biodegradable'' as used in the VGP.
The final standard for oil-to-sea interfaces includes EAL
requirements as part of a general standard for oil management
applicable to any specific discharge that may have an oil-to-sea
interface rather than a specific discharge standard. See 40 CFR
139.6(e). Further, the standard covers all oil-to-sea interfaces on
vessels rather than specifically identified interfaces. Id. EPA notes
that certain types of seals used on below-deck equipment, such as air
seals, are based on designs that use an air gap or other mechanical
features to prevent oils from reaching waters at the exterior of the
vessel's hull. If these seals do not allow the lubricant to be released
under normal circumstances, they are not considered to be oil-to-sea
interfaces. See 40 CFR 139.2 (an ``oil-to-sea interface'' has a
``design [ ] such that oil or oily mixtures can escape directly into
surrounding waters'') (emphasis added). Determinations of technical
infeasibility regarding the use of an EAL pertain to implementation and
therefore would fall under the USCG's implementing regulations
established under CWA section 312(p)(5). The scope of this discharge
category extends to all types of equipment with direct oil-to-sea
interfaces, including any equipment on-deck or mounted to the exterior
of the vessel hull. See 40 CFR 139.2 (definition of ``oil-to-sea
interface''). While the VGP provided that a lubricant could be
classified as an EAL if it was either ``biodegradable,'' ``minimally-
toxic,'' and ``not bioaccumulative'' or labeled under a defined list of
labeling programs (e.g., the European Union's European Ecolabel and
Germany's Blue Angel), the final rule does not include a list of
acceptable labeling programs. This is because neither EPA nor the USCG
can control future modifications to the criteria by these
organizations. EPA expects that all or most of the labeling programs
identified in the VGP will meet the EAL criteria in this final rule and
subsequent USCG implementing regulations, such that a comparable
selection of appropriate lubricants will be available to vessel
operators.
B. Discharges Incidental to the Normal Operation of a Vessel--Specific
Standards
This section describes the final specific Federal standards of
performance for discharges incidental to the normal operation of a
regulated vessel. The final Federal standards of performance apply to
regulated vessels operating within the waters of the United States or
the waters of the contiguous zone. The final rule requires that a
discharge comprised of two or more regulated incidental discharges must
meet the Federal standards of performance established for each of those
commingled discharges.
1. Ballast Tanks
a. Background and Applicability
The final rule incorporates the CWA section 312(p)(1) definition of
``ballast water'' to mean any water, suspended matter, and other
materials taken onboard a vessel to control or maintain trim, draft,
stability, or stresses of the vessel, regardless of how any such water
or suspended matter is carried; or taken onboard a vessel during the
cleaning, maintenance, or other operation of a ballast tank or ballast
management system of the vessel. 40 CFR 139.2. This statutory
definition is slightly expanded and clarified from the VGP, which
included the USCG definition of the term, meaning any water and
suspended matter taken on board a vessel to control or maintain, trim,
draught, stability, or stresses of the vessel, regardless of how it is
carried. VGP appendix A; 33 CFR 151.1504. The term ``ballast water''
does not include any substance that is added to the water that is
directly related to the operation of a properly functioning ballast
water management system (BWMS). In response to several commenters, EPA
is clarifying here that the definition of ``ballast water'' does not
include discharges of fresh water, sea water, or ice carried onboard a
vessel for food safety and product quality purposes and as such are not
subject to the ballast water requirements in the final rule. The final
rule carries forward the definition of ``ballast tank'' from the
appendix A of the VGP to mean any tank or hold on a vessel used for
carrying ballast water, regardless of whether the tank or hold was
designed for that purpose. 40 CFR 139.2.
Ballast water discharge volumes and rates vary significantly by
vessel type, ballast tank capacity, and type of deballasting equipment
for the universe of vessels covered under the rule. Most passenger
vessels have ballast capacities of less than 5,000 cubic meters
(approximately 1.3 million gallons) of water. Cargo/container ships
generally have ballast capacities of five to 20 thousand cubic meters
(more than 1.3 to 5.3 million gallons) of water while some bulk
carriers and tankers have ballast capacities greater than 40 thousand
cubic meters (over 10 million gallons) of water.
Ballast water may contain toxic and nonconventional pollutants such
as rust inhibitors, epoxy coating materials, zinc or aluminum (from
anodes), iron, nickel, copper, bronze, silver, and other material or
sediment from inside the tanks, pipes, or other machinery. Ballast
water may also contain organisms that originate from where the water is
collected. When ballast water is discharged, these organisms may
establish new populations of ANS in the receiving waterbodies. Ballast
water discharged from vessels has been, and continues to be, a
significant environmental concern because it can introduce and spread
ANS that threaten the diversity and abundance of native species; the
ecological stability of U.S.
[[Page 82092]]
waters; and the commercial, agricultural, aquacultural, and
recreational use of those waters.
Prior to passage of the VIDA, ballast water discharges were
regulated by multiple Federal and State laws and regulations. The USCG
regulated ballast water discharges under the Nonindigenous Aquatic
Nuisance Prevention and Control Act of 1990 (NANPCA), and amendments
thereto by the National Invasive Species Act (NISA) of 1996 (33 CFR
part 151 subparts C and D). EPA regulated ballast water discharges
under the VGP through the NPDES program authorized under CWA section
402. However, the VIDA established that ballast water will now be
regulated as an incidental discharge under a new CWA section 312(p).
The VIDA set as a presumptive minimum baseline the existing VGP
requirements.
Additionally, several states (California, Michigan, Minnesota,
Ohio, Oregon, Washington, and Wisconsin) previously used their
certification authorities under CWA section 401 or under standalone
State authorities to impose additional, State-specific requirements on
commercial vessels operating within their State waters. The existing
USCG and EPA requirements for ballast water, as well as such additional
standalone State standards, will no longer apply once EPA has
established national standards and the USCG has promulgated
implementing regulations that are final, effective, and enforceable
under the VIDA. 33 U.S.C. 1322(p)(9)(A)(i).
The final standards for ballast water reflect BAT considering the
specified statutory factors for BAT under CWA section 304(b), as well
as the previous requirements established in the VGP and 33 CFR part 151
subparts C and D, and the new requirements established in the VIDA.
b. Exclusions
The final standards for ballast water apply to any vessel equipped
with one or more ballast tanks that operates in the waters of the
United States or waters of the contiguous zone, except as excluded by
statute or regulation. Pursuant to CWA section 312(p)(2)(B)(ii), the
final rule excludes ballast water discharges from the following five
vessel categories from the CWA section 312(p) ballast water standards:
(1) vessels that continuously take on and discharge ballast water in a
flow-through system; (2) vessels in the National Defense Reserve Fleet
scheduled for disposal; (3) vessels discharging ballast water
consisting solely of water taken onboard from a public or commercial
source that, at the time the water is taken onboard, meets the Safe
Drinking Water Act requirements; (4) vessels carrying all permanent
ballast water in sealed tanks; and (5) vessels discharging ballast
water into a reception facility. 40 CFR 139.10(b).
i. Vessels That Continuously Take on and Discharge Ballast Water in a
Flow-Through System
The final rule excludes discharges of ballast water from a vessel
that continuously takes on and discharges ballast water in a flow-
through system, if the Administrator determines that the system cannot
materially contribute to the spread or introduction of an ANS from
ballast water into waters of the United States or the contiguous zone
(40 CFR 139.10(b)(1)), acknowledging that such a flow-through system
may have additional areas on the hull (e.g., niches) requiring more
rigorous biofouling management. EPA is unaware of any such vessels
currently in commercial operation, but theoretically a vessel could be
designed to have ambient water flow through the hull for vessel
stability without retaining any of that water in such a way that it
would be transported. Should any such vessel begin commercial
operation, EPA expects that it would evaluate the ballasting
configuration to determine if the vessel meets the statutory
description, in which case it would be excluded from the ballast water
discharge standards. In that instance, the Administrator would notify
the vessel owner/operator of such a determination. 40 CFR 139.10(b)(1);
33 U.S.C. 1322(p)(2)(B)(ii)(I).
ii. Vessels in the National Defense Reserve Fleet Scheduled for
Disposal
The final rule excludes discharges of ballast water from a vessel
in the National Defense Reserve Fleet \7\ that is scheduled for
disposal if the vessel does not have an operable BWMS. 40 CFR
139.10(b)(2); 33 U.S.C. 1322(p)(2)(B)(ii)(II).
---------------------------------------------------------------------------
\7\ This includes a fleet of vessels, established by section 11
of the Merchant Ship Sales Act of 1946, reserved for national
defense and national emergencies.
---------------------------------------------------------------------------
iii. Vessels Discharging Ballast Water Consisting Solely of Water
Meeting the Safe Drinking Water Act Requirements
The final rule excludes discharges of ballast water from a vessel
that consist solely of water taken onboard from a public or commercial
source that, at the time the water is taken onboard, meets the
applicable requirements of the Safe Drinking Water Act (SDWA) (42
U.S.C. 300f et seq.) at 40 CFR parts 141 and 143. 40 CFR 139.10(b)(3);
33 U.S.C. 1322(p)(2)(B)(ii)(III). In plain terms, this means that
vessels may use and discharge finished, potable water as ballast, but
may not use or discharge untreated water from a public water system
that is not necessarily potable.
The exclusion in final rule, unlike the proposed exclusion, does
not categorically apply to water taken onboard that meets Health
Canada's Guidelines for Canadian Drinking Water Quality because EPA
determined that the implementation details of this Congressionally-
mandated exclusion, such as identification of potable water sources
consistent with SDWA regulations, may be more appropriately left to the
USCG as part of its implementation, compliance, and enforcement
requirements under CWA section 312(p)(5). EPA does not have information
suggesting vessels made use of a comparable allowance present in the
VGP for water meeting Health Canada's Guidelines, and the USCG ballast
water regulations in 33 CFR part 151 did not provide for a comparable
allowance. Thus, prior to the VIDA, this allowance for water meeting
Health Canada's Guidelines applied solely to the universe of vessels
regulated under the VGP but not USCG regulations (namely, vessels
operating on the Great Lakes). However, an industry representative for
U.S.-flagged vessels operating on the Great Lakes commented on the
proposed rule that it is not operationally or economically feasible for
a U.S.-flagged vessel to receive water meeting potable water
requirements. Thus, while the intent of EPA's proposed rule was to
retain the expanded exclusion from the VGP to include potable water
used as ballast that meets Health Canada's Guidelines, the final rule
does not include such expansion to more closely align with the
statutory language and consistent with information in a comment EPA
received demonstrating that the requirement would not be
technologically available and economically achievable. EPA acknowledges
that vessels discharging ballast water consisting solely of water taken
onboard from public or commercial water sources may be deemed to be
consistent with applicable requirements of the SDWA and that the USCG
may establish procedures for use of such water as a means to comply
with the ballast water discharge standard. EPA anticipates that USCG
may address this issue as a matter of implementation, compliance, and
enforcement in its corresponding rulemaking under the VIDA.
[[Page 82093]]
iv. Vessels Carrying All Permanent Ballast Water in Sealed Tanks
The final rule excludes discharges of ballast water from a vessel
that carries all permanent ballast water in sealed tanks that are not
subject to discharge. 40 CFR 139.10(b)(4). The final rule did not carry
through the phrase ``except under emergency circumstances'' from the
proposed rule in recognition that 40 CFR 139.1(b)(3) excludes
discharges from VIDA regulation if compliance with this part would
compromise the safety of life at sea. This 40 CFR 139.1(b)(3) exclusion
would cover discharges of ballast water from a sealed tank in emergency
circumstances. As such, clarification about emergency circumstances
specific to discharges from sealed tanks is duplicative and
unnecessary. This 40 CFR 139.10(b)(4) exclusion is different from the
ballast water exchange and saltwater flush exemptions described in
section VIII.B.1.h. of this preamble, Ballast Water Exchange and
Saltwater Flush. 33 U.S.C. 1322(p)(2)(B)(ii)(IV).
v. Vessels Discharging Ballast Water Into a Reception Facility
The final rule excludes discharges of ballast water from a vessel
that only discharges ballast water into a reception facility (which
could include another vessel for the purpose of storing or treating
that ballast water). In such instances, once the ballast water is
offloaded to a reception facility, that ballast water would be subject
to any applicable regulation for discharges from that reception
facility. Consistent with the rationale provided in the 2013 VGP Fact
Sheet, EPA would continue to expect that all vessel piping and
supporting infrastructure up to the last manifold or valve immediately
before the reception facility manifold connection, or similar
appurtenance, prevents untreated ballast water from being discharged.
Any such discharge not meeting this requirement would be expected to
meet the ballast water discharge standards in the final rule. 40 CFR
139.10(b)(5); 33 U.S.C. 1322(p)(2)(B)(ii)(V).
c. Exemption From Existing USCG Regulations for Crude Oil Tankers Not
Adopted
Crude oil tankers engaged in coastwise trade are exempted from the
existing USCG regulation (33 CFR 151.2015(b)), consistent with section
1101(c)(2)(L) of the NISA (16 U.S.C. 4711). However, these same vessels
are not exempted from meeting the ballast water requirements in the VGP
and are not exempted under the VIDA. Therefore, pursuant to CWA section
312(p)(4)(B)(iii), which requires this rule to be at least as stringent
as specified parts of the VGP, the final rule does not exempt crude oil
tankers engaged in coastwise trade from meeting the ballast water
requirements set forth in the rule. Such vessels are not inherently
unable to perform ballast water exchanges and other ANS management
practices that their non-exempt counterparts routinely carry out. EPA
expects this final rule to impose no additional costs given that the
requirements are presently in effect under the VGP.
d. Ballast Water Best Management Practices
Pursuant to CWA section 312(p)(4)(B)(ii), the final rule includes
six ballast water BMPs for all vessels with ballast tanks and one
additional ballast water BMP specific to Lakers to control or abate the
number of organisms taken up and discharged in ballast water. 40 CFR
139.10(c). The final rule retains many of the ballast water BMPs
included in the VGP (and present in USCG regulations at 33 CFR part 151
subpart D), in line with the VIDA's requirement that EPA's standards be
at least as stringent as the VGP with limited exceptions. At present,
the ballast water BMPs in this section are widely implemented and EPA
has not identified any unacceptable non-water quality environmental
impacts (e.g., energy requirements, air impacts, solid waste impacts,
and changes in waters use) related to these practices. These are
demonstrated practices that EPA finds to be technologically available
and economically achievable.
The final rule does not include one ballast water BMP that was
included in both the VGP and USCG regulations at 33 CFR part 151
subparts C and D. The final rule does not require that vessel operators
minimize or avoid uptake of ballast water in the following areas and
situations: areas known to have infestations or populations of harmful
organisms and pathogens (e.g., toxic algal blooms); areas near sewage
outfalls; areas near dredging operations; areas where tidal flushing is
known to be poor or times when a tidal stream is known to be turbid; in
darkness, when bottom-dwelling organisms may rise in the water column;
where propellers may stir up the sediment; and areas with pods of
whales, convergence zones, and boundaries of major currents.
This change is based on extensive conversations with the USCG and
comments received indicating that such requirements are not practical
to implement or enforce. During these conversations, new information
from implementation of the VGP became available indicating that these
conditions are not well-defined and are typically beyond the control of
the vessel operator during the uptake and discharge of ballast water.
Additionally, it is difficult for enforcement agencies to assess
whether a vessel operator took appropriate actions as necessary to
comply with these requirements. Therefore, it is not practical to
continue to require that vessels minimize or avoid uptake of ballast
water in those areas and situations. 33 U.S.C. 1314(b)(2)(B) and 33
U.S.C. 1322(p)(4)(D)(ii)(II)(aa). In lieu of including the uptake
measures as individual requirements, EPA expects that appropriate
vessel-specific ballast water BMPs will be incorporated into the
ballast water management plans (BWMPs) discussed later in this section,
as vessels must minimize the introduction and spread of ANS. For
example, BWMPs could describe coordinating with local authorities to
identify areas and situations of concern and any opportunities to
mitigate potential issues. Demonstrating that these important
considerations were made by vessel operators would provide for
environmental protection but allow vessel operators to tailor measures
specific to their vessel operations and routes.
Additionally, the VIDA authorizes a State to petition EPA to issue
an emergency order as provided for in CWA section 312(p)(7)(A)(i) and
in accordance with the procedures outlined in 40 CFR 139.50 in the
event of a known outbreak of harmful algal blooms or other emergency
situations. Similarly, the VIDA authorizes EPA to require, by order,
the use of an emergency BMP for any region or category of vessels if it
is necessary to reduce risk of introduction or establishment of ANS, or
if EPA determines that the order will mitigate the adverse effects of a
discharge that contributes to a violation of a water quality
requirement under CWA section 303. 33 U.S.C. 1322(p)(4)(E)(i). Thus,
similar BMPs may be established albeit through an order where EPA and/
or the USCG identify specific instances when and where such practices
must be implemented.
i. Develop a Ballast Water Management Plan
The final rule requires vessels equipped with ballast tanks to
maintain a BWMP that addresses both the uptake and discharge of ballast
water. 40 CFR 139.10(c)(1)(i). A vessel's BWMP must
[[Page 82094]]
describe the vessel-specific (i.e., considering the unique operational
profile of the vessel) ballast water management practices and systems
that, ensure compliance with the requirements in this section. Specific
details of the BWMP, including how vessel operators are to implement
and follow the plan, would fall under the USCG's implementing
regulations established under CWA section 312(p)(5).
In general, this carries forward the requirement in part 2.2.3.2 of
the VGP requiring a vessel-specific BWMP be developed and maintained.
The VGP specifies, that at a minimum, the plan is to outline how the
vessel will comply with all the VGP ballast water requirements.
Additionally, the requirement to maintain a BWMP is consistent with
existing USCG regulations at 33 CFR 151.2050. Through these
regulations, promulgated pursuant to the NISA, the USCG has required
the individual in charge of any vessel equipped with ballast water
tanks that operates in the waters of the United States to maintain a
BWMP that has been developed specifically for the vessel and that will
allow those responsible for the plan's implementation to understand the
vessel's ballast water management strategy and comply with the
requirements. The USCG also required BWMPs to include detailed
biofouling maintenance and sediment removal procedures (33 CFR
151.2050(g)(3)).
ii. Minimize Use of Gravity To Drain Ballast Tanks in Port
The final rule requires that vessels minimize the use of gravity to
drain ballast tanks while in port. 40 CFR 139.10(c)(1)(ii). Instead,
ballast tanks should be discharged in port using pumps. This BMP has
been shown to increase the mortality rate of living organisms in
ballast water during discharge, particularly zooplankton and other
larger organisms, as a result of the physical action of the pumps
(e.g., cavitation, entrainment, and/or impingement), and thereby reduce
the propagule pressure.
iii. Use High Sea Suction
The final rule requires that, when practicable, high sea suction
sea chests must be used in port or where clearance to the bottom of the
waterbody is less than five meters to the lower edge of the sea chest.
40 CFR 139.10(c)(1)(iii). An example of when the use of high sea
suction may not be practicable is when it is necessary to avoid ice,
algae, or other biofilm on the water surface. This BMP minimizes the
potential for uptake of bottom-dwelling organisms, suspended solids,
particulate organic carbon, and turbidity into the ballast tanks.
iv. Avoid Ballast Water Discharge or Uptake in Areas With Coral Reefs
The final rule requires vessel owners/operators to avoid the
discharge or uptake of ballast water in areas with coral reefs. 40 CFR
139.10(c)(1)(iv). This BMP is consistent with the VGP requirements;
however, the VGP also included similar prohibitions for ``marine
sanctuaries, marine preserves, marine parks, . . . or other waters''
listed in appendix A. The final rule carries forward these prohibitions
in a section specific to activities in federally-protected waters, as
described in section VIII.C. of this preamble, Discharges Incidental to
the Normal Operation of a Vessel-Federally-Protected Waters
Requirements and in the regulations at 40 CFR 139.40.
Further, consistent with a USCG Marine Safety Information Bulletin
(Ballast Water Best Management Practices to Reduce the Likelihood of
Transporting Pathogens That May Spread Stony Coral Tissue Loss
Disease), ballast water discharges should be conducted as far from
coral reefs as possible, regardless of whether the reef is inside or
outside of 12 NM from shore (USCG, 2019a).
v. Clean Ballast Tanks Periodically and Prohibit Ballast Tank Cleaning
Discharges
The final rule requires ballast tanks to be cleaned periodically to
remove sediment and biofouling organisms. 40 CFR 139.10(c)(1)(v).
Residual sediment left in ballast tanks can negatively affect the
ability of a vessel to meet discharge standards, even when a BWMS is
properly operated and maintained. Sediments may also allow organisms to
survive in ballast tanks for prolonged periods of time in resting
stages. Additionally, the final rule prohibits the discharge of
sediment from ballast tank cleanings in waters subject to this rule.
vi. Maintain Sea Chest Screens
The final rule requires that sea chest screen(s) be maintained and
kept fully intact. 40 CFR 139.10(c)(1)(vi). This BMP is consistent with
a VGP requirement for existing bulk carriers operating exclusively in
the Laurentian Great Lakes (Lakers), but the final rule expands it to
all vessels with ballast tanks. These screens are designed to prevent
the largest living organisms, such as fish, as well as bacteria and
viruses associated with these organisms, from entering ballast tanks.
Adequately maintaining sea chest screens is a simple technology-based
practice that is available, economically achievable, and beneficial to
all vessels to reduce the transport of organisms.
vii. New Laker Equipment Standard
The final rule establishes, as a BMP, a ballast water ``equipment
standard'' that requires any new Laker to install, operate, and
maintain a USCG type-approved BWMS. 40 CFR 139.10(c)(2). EPA's standard
for new Lakers aligns with the ``technology-forcing'' nature of the BAT
statutory standard. See NRDC v. EPA, 822 F.2d 104, 123 (D.C. Cir.
1987); See also Southwestern Elec. Power Co. v. EPA, 920 F.3d at 1003
(``By requiring BAT, the Act forces implementation of increasingly
stringent pollution control methods.''). This approach is consistent
with the option discussed in the supplemental notice. Discussion of
EPA's rationale for exempting both new and existing Lakers from the
numeric ballast water discharge standard is provided in section
VIII.B.1.f.v. of this preamble, Vessels that Operate Exclusively in the
Laurentian Great Lakes.
The final rule defines a ``new Laker'' as any vessel 3,000 GT and
above, and that operates exclusively in the Great Lakes and the St.
Lawrence River west of a rhumb line drawn from Cap des Rosiers to
Pointe-de-l'Ouest (West Point), Anticosti Island, and west of a line
along 63[deg] W. longitude from Anticosti Island to the north shore of
the St. Lawrence River, and constructed after the effective date of
USCG regulations promulgated pursuant to CWA section 312(p)(5)(A)(i).
40 CFR 139.2. The final definition for, and use of the term, ``new
Laker'' corrects an improper citation in the supplemental notice to the
French spelling of ``West Point'' to correctly read ``Pointe-de-
l'Ouest'' not ``Pointe-Sude-Oueste.'' The final definition for
``seagoing vessel'' was also corrected to reference ``Pointe-de-
l'Ouest.''
As described in section VIII.B.1.e.i.1 of this preamble, BAT for
Control of Ballast Water Discharges is the Use of a USCG Type-Approved
BWMS, the requirement to use a type-approved BWMS is a well-established
and demonstrated process for selection of technologies. The final rule
requires the use of a USCG type-approved BWMS because this process
comprehensively addresses BWMS design, installation, operation, safety,
and performance.
Land-based and shipboard testing of ultraviolet (UV) and chemical
addition BWMSs in the Great Lakes have demonstrated a substantial
reduction in organisms even when the numeric
[[Page 82095]]
discharge standard cannot be achieved (GSI, 2011; GSI 2015; Bailey et
al., 2023). An equipment standard allows vessels flexibility to operate
BWMSs in challenging water conditions through use of operational
contingency measures. Additionally, these implementation details can be
determined in the USCG regulations. Although contingencies may be
necessary in certain locations or at certain times of the year in the
Great Lakes, EPA expects that continued operation of a BWMS consistent
with an equipment standard over the lifetime of a vessel will still
provide reductions in the discharge of organisms. Additionally, new
Lakers can be designed and constructed to accommodate a USCG type-
approved BWMS and overcome certain operational and technical challenges
such as corrosion, flow rate capacity, lack of space and lost cargo
capacity, and adequate power.
As described in the supplemental notice in section IV.B., Ballast
Tanks--Equipment Standard for New Lakers (88 FR 71788, October 18,
2023), the final rule does not establish an equipment standard for
existing Lakers as BAT because technical and operational challenges
would create disproportionately high costs to retrofit BWMSs onto
existing Lakers. See 88 FR 71800, October 18, 2023, section IV.B.3.I.
Existing Lakers also do not have the engineering flexibility available
during the initial design and construction process to incorporate
ballast water treatment capabilities.
Also, two provisions in the VIDA, when read together, demonstrate
Congress' intent for EPA to undertake additional research to develop
effective ballast water management solutions for existing Lakers.
First, section 903(g) of the VIDA authorized the EPA Administrator to
establish the Great Lakes and Lake Champlain Invasive Species Program
within the Great Lakes National Program Office that has as one of its
purposes ``to develop, achieve type-approval for, and pilot shipboard
or land-based ballast water management systems installed on, or
available for use by, commercial vessels operating solely within the
Great Lakes and Lake Champlain Systems to prevent the spread of aquatic
nuisance species populations within the Great Lakes and Lake Champlain
Systems.'' This program is to be developed in collaboration and
consultation with several other Federal agencies. As described therein,
``commercial vessels operating solely within the Great Lakes and Lake
Champlain Systems'' are, as defined by EPA, ``Lakers.'' Thus, Congress
clearly intended for EPA to work towards finding ballast water
management solutions for existing Lakers and acknowledged that there
were special technological challenges presented by Lakers. Second,
section 903(a)(1) of the VIDA, specifically as codified in CWA section
312(p)(6)(C), established a ``period of use of installed BWMSs'' clause
that specifies that a vessel is deemed to be in compliance if the
vessel is meeting the ballast water discharge standard that was
applicable to the vessel at the time of installation of the existing
BWMS, even if EPA subsequently establishes a more stringent discharge
standard. Thus, an existing Laker required to install a BWMS to meet
the discharge standard would be unlikely to benefit from any improved
ballast water management practices developed as part of the ballast
water research. EPA's seven-year Great Lakes Ballast Water Research and
Development Plan is targeted to address the complexities and improve
the operation of BWMSs on existing Lakers. EPA is also required to
review and revise as appropriate its VIDA standards of performance
every five years. 33 U.S.C. 1322(p)(4)(D)(i). As such, EPA expects the
outcome of that research will support future discharge requirements for
these vessels with a focus on finding effective technologies for the
management of ballast water.
e. Numeric Ballast Water Discharge Standard
EPA is establishing BAT effluent limitations for ballast water
based on the technologies required by the VGP and USCG ballast water
regulations. The final rule at 40 CFR 139.10(d) continues, as a numeric
discharge standard, the numeric limitations for biological parameters
from the VGP and USCG ballast water regulations at 33 CFR part 151
subpart D, as follows:
Organisms greater than or equal to 50 micrometers in
minimum dimension: discharge must include less than 10 living organisms
per cubic meter of ballast water.
Organisms less than 50 micrometers and greater than or
equal to 10 micrometers: discharge must include less than 10 living
organisms per milliliter (mL) of ballast water.
Indicator microorganisms must not exceed:
[cir] Toxicogenic Vibrio cholerae (serotypes O1 and O139): a
concentration of less than 1 colony-forming unit (cfu) per 100 mL.
[cir] Escherichia coli: a concentration of less than 250 cfu, or
Most Probable Number (MPN), per 100 mL.
[cir] Intestinal enterococci: a concentration of less than 100 cfu,
or MPN, per 100 mL.
The final rule defines ``living'' using the CWA section
312(p)(6)(D) clarification that the terms ``live'' and ``living'' shall
not include an organism that has been rendered nonviable or preclude
the consideration of any method of measuring the concentration of
organisms in ballast water that are capable of reproduction. 40 CFR
139.2. However, it is important to recognize that, to date, the USCG
has not identified any testing protocols, based on best available
science, that are available for use to quantify organisms in ballast
water that are capable of reproduction. As such, demonstrating
compliance with the discharge standard would require the use of test
methods, as detailed in the 2010 EPA Generic Protocol for the
Verification of Ballast Water Treatment Technology, that do not
consider non-viable organisms as part of the test protocol (U.S. EPA,
2010). In the future, should the USCG identify one or more testing
protocols that enumerate organisms in ballast water capable of
reproduction, such methods would be acceptable for demonstrating
compliance with the numeric ballast water discharge standard.
The final rule reflects units of both MPN/mL and cfu/mL for
Escherichia coli and intestinal enterococci in 40 CFR 139.10(d), and
(g)(2) for the Pacific Region, based on input from commenters who
pointed out that newer microbiological test methods have MPN outputs
and that, while the test methods differ, the number of bacteria in the
tested sample are comparable to the numeric discharge standard.
In addition, the final rule at 40 CFR 139.10(d)(2) continues the
discharge limitations as a numeric standard for four biocide parameters
contained in the VGP, namely:
For any BWMS using chlorine dioxide, the chlorine dioxide
must not exceed 200 [mu]g/L;
For any BWMS using chlorine or ozone, the total residual
oxidizers must not exceed 100 [mu]g/L; and
For any BWMS using peracetic acid, the peracetic acid must
not exceed 500 [mu]g/L and the hydrogen peroxide must not exceed 1,000
[mu]g/L.
The standard for both the organisms and biocide parameters
represents instantaneous maximum values not to be exceeded.
The final rule continues the requirement contained in the VGP and
USCG regulations (33 CFR part 151) that, prior to the compliance date
for the vessel to meet the discharge standard,
[[Page 82096]]
ballast water exchange must be conducted as required in 40 CFR
139.10(e), or the applicable regional requirements in 40 CFR 139.10(f)
and (g), for any vessel subject to the ballast water discharge
standard. The USCG is required to include compliance dates in its
implementing regulations established under CWA section
312(p)(5)(A)(iv).
For the reasons described in the following section, BAT for ballast
water management remains the use of a USCG type-approved BWMS as
required long-term under the USCG ballast water regulations and VGP.
Accordingly, that is the technology on which EPA has based the numeric
ballast water discharge standard.
i. BAT Rationale for Standard Pursuant to the VIDA
(1) BAT for Control of Ballast Water Discharges Is the Use of a USCG
Type-Approved BWMS
(a) EPA Conducted a Comprehensive Survey of Technologies for Purposes
of Identifying BAT
EPA based its analysis of prospective BAT model technologies
largely on data generated through the USCG BWMS type-approval process.
In response to concerns expressed by commenters that EPA failed to
review sufficient data for the proposed rule, EPA requested and
obtained directly from the USCG a large set of land-based and shipboard
USCG BWMS type-approval data for the 37 BWMSs that had been type-
approved as of the date of the proposed rule (October 2020) and similar
data for 16 amendments to those systems. In total, EPA analyzed 1,820
treatment discharge results from 49 BWMS type-approval data sets. The
complete set of USCG BWMS type-approval data provided to EPA by the
USCG and the Agency's comprehensive Ballast Water BAT Data Analysis of
these data, including a sensitivity analysis, are included in the
docket (U.S. EPA, 2023), and are updated for the final rule (U.S. EPA,
2024). As of April 30, 2024, the USCG has type-approved 54 BWMSs. Some
commenters suggested that EPA should analyze more recent data. However,
EPA is unaware of any significant improvements in ballast water
technology, monitoring, or testing. As such, allowing more time for the
USCG to compile and share additional data with EPA on additional
systems that have been type-approved since the proposed rule would not
have meaningfully altered the results of the analysis. Additionally, it
takes significant time for USCG to compile and share data with EPA. For
example, EPA received USCG data 16 months after the initial formal
request to USCG for the compiled type-approval data. Thus, given the
time it takes USCG to compile and share data with EPA, EPA selected an
appropriate cutoff point for the collection of data to enable timely
analysis to proceed.
EPA did not analyze IMO type-approval data for its BAT analysis
here, and EPA's rationale for excluding IMO type-approval data from its
analysis is described in both the proposed rule and supplemental notice
(85 FR 67818, October 26, 2020, section VIII.B.1.v.A.3.i. and 88 FR
71788, October 18, 2023, section III.A.1).
(b) USCG Type-Approved BWMSs Are Technologically Available and
Economically Achievable
Based on its review of available information, for this final rule,
EPA selected all currently available USCG type-approved BWMSs as BAT
for control of ballast water discharges. EPA's final rule includes a
numeric ballast water discharge standard based on that technology. This
outcome is consistent with the requirements in the VGP, which also
identifies USCG type-approved BWMS as BAT and has the same numeric
standards as the final rule.
EPA has determined that the standard for ballast water discharges
in the final rule is technologically available and economically
achievable. This determination is based in part on the fact that EPA
assessed the same type-approval process and similar technologies under
the VGP and determined that USCG type-approved BWMS were
technologically available and economically achievable for that permit.
As discussed in more depth below, EPA assessed additional data
regarding USCG type-approved systems and, based both on its prior
analysis and new data and analysis, continues to find the suite of USCG
type-approved BWMSs to be BAT. Additionally, vessels in the United
States have been required to meet the same numeric standard reflecting
USCG type-approved BWMSs as BAT under the 2013 VGP, which further
supports EPA's determination that such systems are technologically
available and economically achievable.
The fact that these systems are approved through the USCG's type-
approval process also supports their availability for use on the full
universe of vessels regulated by the VIDA. USCG regulations include
BWMS type-approval requirements that consider design, installation,
operation, and testing to ensure any type-approved system meets both
performance and safety standards. 46 CFR 162.060. The type-approval
process also supports the availability of these systems despite the
challenges vessels present that are not present for stationary
facilities for which EPA routinely establishes national discharge
effluent limitations guidelines and standards based on BAT. For
example, the USCG type-approval process separately requires that the
BWMS be practicable onboard a vessel (e.g., able to operate despite
roll, pitch, and vibration considerations), compatible with other
onboard systems, durable, and be supported by credible and sustainable
system manufacturers, suppliers, and servicers. Additionally, to be
installed on any U.S.-flagged vessel, the USCG must verify the system
meets certain installation and engineering requirements specified in 46
CFR subchapters F and J.
(c) USCG Type-Approved BWMSs Have Acceptable Non-Water Quality
Environmental Impacts
EPA also considered non-water quality environmental impacts of its
ballast water standards as part of its BAT analysis. EPA previously
determined for the VGP that its numeric ballast water standards had
acceptable non-water quality environmental impacts, and the Agency is
not aware of any new information since the VGP that would cause EPA to
reach a different determination for this final rule. In particular,
based on its experience implementing this requirement for vessels since
the 2008 VGP, EPA has not found this requirement to have unacceptable
non-water quality environmental impacts. Specifically, EPA has
considered the impacts of its standards related to increased energy
usage for operating treatment equipment and associated greenhouse gases
from an incremental increase in fuel consumption. Any such impacts are
far exceeded by the effluent reduction benefits of treatment.
Additionally, EPA's standard allows vessel operators to select from a
broad range of type-approved systems to best meet their vessel's needs,
including where appropriate to reduce energy requirements. For these
reasons, EPA's ballast water numeric standard will not have
unacceptable non-water quality environmental impacts.
(d) Harmonization With an International Standard Further Supports EPA's
Selection of USCG Type-Approved BWMSs as BAT
In identifying a model BAT technology for this rule, EPA determined
it was appropriate to consider whether its numeric standard
[[Page 82097]]
was harmonious with international standards and promoted international
comity. In particular, for ballast water discharges, the current world
economic and trade system is predicated on timely and efficient
maritime transportation, a significant proportion of which operates
globally where trade takes it. The final numeric ballast water
discharge standard acknowledges, as described in the preamble to the
proposed rule, that a majority of the vessels discharging ballast water
in waters of the United States spend the majority of their time
operating outside of waters of the United States (U.S. EPA, 2020) and
that these vessels for the most part are obligated to comply with the
IMO International Convention for the Control and Management of Ships'
Ballast Water and Sediments (the BWM Convention)--an international
treaty developed with a goal of establishing an international standard
for the management of ballast water (IMO, 2004)--anywhere they operate
in the world, including while operating in the United States. This is
not to say that U.S. requirements must or should always be identical
with the international standard; however, it is appropriate, in EPA's
view, to consider whether U.S. requirements are harmonious with
international obligations for the vessels of flag states that have
signed onto that BWM Convention.
Indeed, the BWMS type-approval process was first developed as part
of the IMO BWM Convention. The BWM Convention was adopted in 2004 after
more than 14 years of complex negotiations between IMO member states
and entered into force in 2017. The United States is not a party to the
BWM Convention; however, both the USCG (serving as the lead for the
U.S. delegation) and EPA were actively involved in the standard setting
discussions that led to the BWM Convention numeric discharge standard
that entered into force in September 2017. The USCG developed domestic
type-approval regulations with the intent to harmonize as closely as
possible with the adopted BWM Convention.
While EPA received comments arguing that it should identify BAT
based on the performance of a subset of the perceived most stringent of
type-approved systems, pollutant discharge reductions are not the sole
factor relevant to BAT under CWA section 304(b). As discussed in more
detail in the proposed rule (85 FR 67818, October 26, 2020, section
VIII.B.1.v.A.2.ii.), the BAT consideration factors in CWA section
304(b), particularly with respect to the ``process employed'' and
``engineering aspects of the application of various types of control
techniques,'' weigh in favor of establishing the ballast water standard
at a level of consistency with the IMO standard. Furthermore, section
304(b)(2)(B) authorizes EPA to consider ``such other factors as the
Administrator deems appropriate'' and EPA has broad discretion in
considering those factors and the weight attributed to such factors.
See Weyerhaeuser Co. v. Costle, 590 F.2d 1011, 1028, 1045 (D.C. Cir.
1978); Texas Oil & Gas Ass'n v. EPA, 161 F.3d 923, 928 (5th Cir. 1998).
Here, EPA considers consistency with the international standard to be
an appropriate factor that weighs in favor of the BAT selected in this
final rule because it promotes international trade and comity.
(e) USCG Type-Approved BWMSs Make Reasonable Further Progress Toward
the National Goal of Eliminating the Discharge of All Pollutants
EPA's ballast water standard based on USCG type-approved systems as
BAT also makes reasonable further progress toward the national goal of
eliminating the discharge of all pollutants. See CWA section
304(b)(2)(B). As detailed in the preamble for the proposed rule, these
systems have been shown to substantially reduce the concentration of
living organisms in ballast water discharges and beyond the reduction
achieved through midocean exchange or unexchanged ballast water.
Specifically, as illustrated in table 1 of the proposed rule, pollutant
discharge reduction attributable to type-approved BWMS performance is
extremely high, with properly operated and maintained systems achieving
treatment efficiencies of more than 99 percent. Furthermore, EPA notes
that vessel ballasting practices to minimize volumes of ballast water
requiring management will likely continue to evolve into the future,
further driving reductions of pollutant discharges.
Opportunities for advancement in ballast water treatment and
technology may involve EPA and/or the USCG assisting the vessel
community in addressing installation and operational challenges with
the existing BWMSs and future type-approved systems and BMPs. The VIDA
provides EPA and the USCG with this opportunity to enhance the ballast
water regulations, which should aid with the operation of demonstrated,
but not yet fully optimized, systems and with future systems as they
continue to be developed and deployed.
(2) EPA Rejects Other Technologies as BAT for Controlling Discharges of
Ballast Water
Some commenters suggested that EPA should identify a single-best
performing BWMS or a subset of better-performing BWMSs and impose that
perceived level of performance on the entirety of the universe of
potentially affected entities. EPA disagrees that the available
information indicates that a higher-performing system or subset of
systems can be identified as BAT from the data in the record.
Additionally, even if higher performing systems could be identified,
the record does not demonstrate that a small subset of systems capable
of meeting a more stringent standard would be available to all vessels
that would be required to meet a standard based on those systems, given
the tremendous variability among vessels.
Based on its analysis of USCG type-approval data described in the
supplemental notice, EPA disagrees with commenters that the record
allows for identification of a subset of so-called best-performing
BWMSs. EPA's analysis specifically addressed commenters' suggestion and
evaluated whether statistical differences in the treatment
effectiveness of BWMSs could help identify systems that perform
significantly better in terms of pollutant discharge reductions, such
that they could reflect BAT. To do so, EPA compared treatment discharge
concentrations of the BWMSs within six groups defined by the two common
organism size class and three salinity categories. Statistical tests
conducted and summarized in the Agency's comprehensive Ballast Water
BAT Data Analysis (U.S. EPA, 2024) showed significant differences among
systems within each group but did not point to any clear stratification
of ``best'' or ``worst'' system groupings. Further complicating this
analysis, the effectiveness of systems varied by organism size and/or
salinity, such that systems had different relative comparisons
depending on the group within which they were evaluated. For example,
one system may have produced lower concentrations in one organism size
class but not in the other size class, making an overall determination
of that system's treatment effectiveness compared to other systems
uncertain.
The results of this statistical analysis did not point to any clear
identification of a subset of BWMSs that stood out as representing BAT.
Test results for both the baseline and sensitivity analyses were within
the same order of
[[Page 82098]]
magnitude as the standard in the proposed rule and fall within the
margin of error expected due to the variability associated with the
characteristics of ballast water and challenges associated with
monitoring, analyzing, and enumerating organisms in the different size
classes. Based on the data analysis of the USCG type-approval data, EPA
did not identify any single system or subset of systems that might be
identified as BAT based on their superior performance in terms of
pollutant discharge reductions.
EPA also disagrees with the suggestion to base BAT on a small
subset of systems because that suggestion does not account for the
substantial variability among vessels. This variability dictates the
need for a range of different BWMS options to adequately address
organism reduction in ballast water discharges. That is, a BWMS that is
technically and operationally appropriate for one vessel or set of
conditions may not be available for a different vessel, or even a
similar vessel with a different operating profile. EPA's BAT
determination carries forward the existing regulatory approach,
promoting the type-approval process using a range of types of BWMS
disinfection technologies that operate under a wide range of
conditions, thereby allowing vessel operators to select a system that
is most appropriate for their vessel. The final rule provides the
necessary flexibility for the vessel owner/operator to select a system
that has been demonstrated through the existing USCG type-approval
process as both capable of achieving the final numeric discharge
standard and as suitable for their particular vessel.
(3) EPA's Numeric Ballast Water Discharge Standard Is Supported by the
Data in the Record
EPA's numeric ballast water discharge standard is supported by the
data in the record for several reasons. First, EPA's experience with
the VGP has demonstrated that the numeric standard is achievable for
vessels subject to regulation under this rule. Based on its BAT
analysis for the VGP and its subsequent administration of the VGP, EPA
has direct knowledge that the numeric standard can be attained.
Second, EPA's standard is based on USCG type-approved systems,
which are designed and demonstrated to allow vessels to consistently
achieve the numeric discharge standard. The goal of the USCG type-
approval process is to demonstrate that a BWMS can treat ballast water
such that organism concentrations in discharged water are sufficiently
low to meet the discharge standard (e.g., less than 10 organisms per
cubic meter of ballast water as an instantaneous maximum) for a given
number of consecutive valid tests. Type-approval is a critical step in
verifying that a BWMS, when tested under standardized and relatively
challenging conditions, is capable of consistently meeting a discharge
standard. In the USCG type-approval testing process to determine
biological efficacy, careful analyses are employed to: (1) assure the
source water for testing meets a threshold concentration of organisms
to meaningfully challenge the BWMS; and (2) to quantify (ideally,
sparse) concentrations of living organisms in treated discharge water.
As part of its type-approval procedure, the USCG regulations require
BWMS land-based testing to be conducted pursuant to the ETV Protocol
(i.e., the 2010 Generic Protocol for the Verification of Ballast Water
Treatment Technology, developed under the now defunct EPA Environmental
Technology Verification Program) that outlines the experimental design,
sampling and analysis protocols, test, and reporting requirements (U.S.
EPA, 2010). This rigorous process ensures that systems are consistently
able to meet EPA's standard.
Third, EPA's numeric standard appropriately accounts for various
sources of variability inherent in addressing organisms (including ANS)
in ballast water, including:
Vessel size and architectural characteristics, including
but not limited to design of ballast tank(s), pump(s), and piping
configuration;
Vessel operational profile (e.g., voyage lengths, volumes
of ballast water, ballast water flow rates, etc.);
Vessel class and flag State;
Temperature, salinity, and turbidity range of uptake water
in areas where the vessel voyages;
Duration of voyages and segments of each voyage that can
affect the necessary holding time for certain systems;
Ballast water capacity and required uptake and discharge
pumping rates;
Treatment system weight and space considerations,
including but not limited to accessibility and acceptability for use in
hazardous spaces;
Availability of service, support, replacement parts,
supplies, etc. in areas where the vessel voyages;
Compatibility of treatment with vessel construction (e.g.,
corrosivity concerns);
Power demand and energy consumption to pump ballast and
operate treatment system; and
Safety concerns (e.g., explosivity risks, particularly on
oil and chemical carriers).
As EPA has historically done with respect to developing effluent
limitations guidelines, EPA is not specifying a single technology that
must be used, but rather it is identifying one or more technologies
that have been demonstrated as being capable of meeting the discharge
standard. The discharger is free to select a technology most suitable
for its operations and compliance (to be determined by USCG) is able to
be demonstrated through routine self-monitoring. The USCG type-approved
its first BWMS in 2016 and, to date, more than fifty systems have been
approved through that process (USCG, 2024). The wide range of systems
demonstrated to meet EPA's numeric standard thus accounts for the
variability in vessel characteristics, operations, and conditions.
(4) EPA Rejects an Alternative Numeric Standard Based on Several
Factors
Commenters suggested that EPA adopt different or lower numeric
standards for ballast water, arguing that EPA's data indicates that a
limit of less than 10 organisms per volume of ballast water as an
instantaneous maximum is not supported by available data as the most
stringent limit that could be set based on USCG type-approved BWMSs.
Specifically, commenters urged that EPA's results indicated that a
numeric standard could be set at 6.01 or 6.66 organisms/volume for
large and medium organisms size classes, respectively, or even at lower
levels based on the results of single systems or subsets of systems.
EPA has carefully considered this issue but disagrees with commenters
for several reasons.
(a) Observed Numeric Differences in Test Results Are Not Scientifically
Significant in Light of Existing Variability
EPA disagrees that the USCG test results that EPA reviewed as part
of this rulemaking indicate that additional pollutant control may be
achieved through the application of a more stringent discharge standard
such as one around 6 organisms. Whether the standard is set at
approximately 6 or 10 organisms, both results are within the margin of
error expected given variability in type-approval sampling and
analysis. For example, stratification in ballast tanks, variability
between tanks, flow rates, and contamination in uptake and discharge
pipes are just a few of the considerations that may impact type-
approval testing. It is also a challenge to capture and count
[[Page 82099]]
appropriately sized organisms and to collect samples such that the
sample collection process does not physically damage or kill these
organisms (which should be counted as dead or nonviable only if such
happens as a result of the BWMS, not because of poor sample collection
and handling practices). Any perceived difference in system performance
could easily be due to the variability in ballast water uptake and
testing, and not necessarily indicative of improvement in treatment
effectiveness that would warrant a revised standard. Indeed, the Second
Circuit has recognized and upheld in the context of measuring aquatic
organisms that discharge standards that are not identical may
nonetheless represent the same level of control. Riverkeeper, Inc. v.
EPA, 358 F.3d 174, 188-89 (2d Cir. 2004) (upholding EPA's Track II
requirements allowing for ``substantially similar'' reductions in
impingement and entrainment at new facility cooling water intake
structures as not a less stringent standard but the same standard
accounting for the measurement margin of error when measuring in the
natural environment).
Even a standard 10 to 100 times more stringent than EPA's would be
insignificant and within the margin of error in terms of the expected
level of pollution control. For example, as EPA explained in its
proposed rule, achieving a standard 10 times more stringent than the
standard in the final rule would result in a difference of between
99.92 and 99.99 percent treatment efficiency for large organisms and
97.82 and 99.78 percent treatment efficiency for medium organisms. From
the perspective of the effectiveness of the technology (and given the
limitations in sampling and monitoring), the differences between 99.92
and 99.99 percent effective are scientifically insignificant.
(b) Alternative Numeric Standards Would Not Account for Variability
A more stringent numeric standard would also fail to account for
the variability inherent in ballast water management. Variability is
inherent to all treatment systems, including well-operated treatment
systems. When EPA establishes BAT, it must consider the variability of
a well-operated treatment system to ensure that technology is available
to achieve the discharge standard. EPA's approach to providing for some
variability for well-operated systems in establishing BAT limits in
effluent limitations guidelines rulemakings has been upheld. For
example, in Nat'l Wildlife Fed'n v. EPA, 286 F.3d 554, 572 (D.C. Cir.
2002), the D.C. Circuit upheld EPA's decision to set the monthly
average at the 95th percentile by stating that EPA has considerable
discretion in determining a technical approach that will ensure that
the effluent limitations reasonably account for the expected
variability in plant operations while still maintaining an effective
level of control. See also Chemical Mfrs. Ass'n v. EPA, 870 F.2d 177,
229 (5th Cir. 1989) (explaining that the purpose of these variability
factors is to account for routine fluctuations that occur in plant
operation, not to allow poor performance). As is typically the case in
the effluent guidelines program, operators design pollution control
systems to achieve results below the discharge standard on a long-term
basis to account for normal variability of well-operated systems.
Setting the numeric standard at the lowest measured levels or long-term
average levels, as some commenters suggested, does not allow for this
normal variability in system performance.
In the case of ballast water, the operators experience an even
greater challenge meeting the numeric discharge standard than would
exist at a shoreside facility subject to a typical effluent guideline.
Instead of the numeric discharge standard being a long-term or monthly
average as it is for most land-based facilities, the VIDA standard is
based on an instantaneous maximum standard, never to be exceeded. EPA
reasonably selected an instantaneous maximum as the unit of time for
compliance monitoring because of the challenges associated with
monitoring, acknowledging that variations in turbidity, salinity,
temperature and other environmental factors can significantly affect a
vessel operator's ability to meet the discharge standard at all times.
BWMS manufacturers must account for these two conflicting challenges--
continuous compliance and inherent variability--in their system design
and operation. BWMS vendors accomplish this by: (1) designing their
systems to achieve long-term average discharge concentrations that are
lower than the numeric discharge standard; and (2) adequately
controlling for variation in BWMS performance such that the system can
meet the numeric discharge standard even in the most challenging
conditions. Designing and operating BWMSs to consistently achieve
levels close to the numeric discharge standard is poor practice because
even relatively slight variability would result in a high rate of non-
compliance with the instantaneous maximum numeric discharge standard
(and would not, for example, pass the USCG type-approval testing
process). This partially explains why some of the test results
described by the Second Circuit Court decision on the VGP were lower
than the current standard. Nat. Res. Def. Council v. EPA, 808 F.3d 566,
570 n.11 (2d Cir. 2015). EPA recognizes that variability in performance
around the long-term average occurs during normal operations and that,
at times, even well-operated BWMSs are certain to discharge at levels
that are higher than the long-term average performance. EPA considered
the need to consistently meet an instantaneous maximum standard given
system variability in setting its numeric standard, but the standards
suggested by commenters fail to do so.
(c) Alternative Numeric Standards Would Present Monitoring Challenges
As described in the proposed rule (85 FR 67818, October 26, 2020,
section VIII.B.1.v.A.3.iv.), there are monitoring challenges associated
with collecting and analyzing ballast water to detect and quantify
organisms at levels lower than the final numeric standard in this rule.
These challenges gave EPA low confidence in the ability of a vessel to
demonstrate compliance with a lower numeric discharge standard. Even
monitoring to assess compliance with the final discharge standard
presents challenges. For example, in the 2013 VGP, the three-component
self-monitoring program excluded monitoring for the two largest
organism size classes because of the difficulties/costs associated with
directly self-monitoring living organisms in ballast water discharges.
Rather, the 2013 VGP established a self-monitoring program that serves
as an indicator of system performance while operating as the system was
designed (and type-approved).
The proposed rule described the practical and statistical
challenges associated with performing the tests that would be necessary
to show that a well-operated BWMS is able to reliably meet a more
stringent or ``no detectable organisms'' standard and after
consideration of relevant comments, EPA also did not adopt a ``no
detectable organisms'' standard in the final rule. There are no
performance data available at concentrations of less than one organism
per volume of ballast water for the two largest organism size classes.
The Agency noted that test methods (and associated method detection
limits) prevent demonstrating that any BWMS can achieve a standard more
stringent than the 2013 VGP numeric discharge limit. EPA highlighted
that, consistent with findings of EPA's Science Advisory
[[Page 82100]]
Board (SAB), it was unreasonable to assume that a test result showing
zero living organisms using currently available test methods
demonstrates complete sterilization, if for no other reason than a
sample taken represents a very small portion of the overall discharge
and the collection of that sample may miss the few live organisms
present in the discharge. Collecting larger volumes of ballast water to
address this uncertainty is also impractical. For example, the SAB
estimated that anywhere from 120 to 600 cubic meters of ballast water
(similar to the amount of water that would be needed to fill about one
to five standard school buses) would have to be collected to adequately
assess whether the discharge meets a standard 10 times more stringent
(U.S. EPA, 2011).
ii. Ballast Water Reception Facilities
EPA received comments urging that it should base BAT on the use of
ballast water reception facilities. The VIDA expressly excludes from
the discharge standards ``ballast water from a vessel . . . that only
discharges water into a reception facility.'' 33 U.S.C.
1322(p)(2)(B)(ii)(V). As such, CWA section 312(p) does not authorize
EPA to regulate the transfer of ballast water from ships to a reception
facility under the VIDA. Nonetheless, for purposes of the final rule
and consistent with the 2015 Second Circuit Court decision on the VGP,
EPA reviewed and considered whether zero discharge or a more stringent
discharge standard based on the use of a reception facility may be BAT
for ballast water discharged from regulated vessels. Nat. Res. Def.
Council v. EPA, 808 F.3d 566, 572-75 (2d Cir. 2015). Unless otherwise
noted, the terms ``onshore'' and ``reception facility'' refer to both
the transfer of ballast water to either an onshore reception facility
or another vessel for the purpose of storing or treating that ballast
water.
For the reasons detailed in the proposed rule (85 FR 67818, October
26, 2020, section VIII.B.1.v.B.), based on the record before it, EPA
continues to conclude that reception facilities are not technologically
available or economically achievable at this time for the purpose of
establishing a uniform Federal discharge standard. While EPA
understands that the use of reception facilities, if available, may be
a valid and effective component of ballast water management in certain
situations, the challenges in creating such a comprehensive
infrastructure nationwide make reception facilities not technologically
available as BAT. (See 85 FR 67818, October 26, 2020, section
VIII.B.1.v.B., for a more detailed explanation of EPA's consideration
of ballast water reception facilities as BAT.) It is unlikely that
ballast water reception facilities could become a national ``one size
fits all'' option for ballast water management, principally because it
cannot accommodate widely varying trade routes without the availability
of reception facilities in most ports. Port-specific conditions may
also preclude any technologically available and/or economically
achievable reception facility alternatives. Integration with port and
vessel operations would require careful planning, design, and
operation. If in the future reception facilities become available and
economically achievable and have acceptable non-water quality
environmental impacts in specific locations for certain specialized
sectors of the commercial vessel industry, EPA can revisit the
standards. For now, such an option has not been demonstrated to reflect
BAT. EPA's finding that reception facilities do not represent BAT for
purposes of establishing a Federal standard does not preclude a vessel
from using such a facility for managing its ballast water where such an
opportunity exists.
f. Exemptions From the Numeric Ballast Water Discharge Standard
The final rule exempts certain vessels from the numeric ballast
water discharge standard as specified in 40 CFR 139.10(d)(3). These
exemptions are generally consistent with the VGP and USCG regulations
(33 CFR part 151 subparts C and D) except as described below. In
contrast to the exclusions in 40 CFR 139(b) that exclude certain
vessels from the ballast water discharge standard in its entirety, the
eight exemptions in 40 CFR 139.10(d)(3)(i) through (viii), as described
in this section, exempt vessels from the numeric ballast water
discharge standard in 40 CFR 139.10(d) only. Exempt vessels are
required to meet the ballast water BMPs and the ballast water exchange
and saltwater flush requirements included in 40 CFR 139.10(c) and (e),
respectively, as applicable. These exemptions are generally consistent
with the VGP and USCG regulations (33 CFR part 151 subparts C and D),
with some exceptions.
i. Vessels Less Than or Equal to 3,000 GT (1,600 GRT if GT Is Not
Assigned) and That Do Not Operate Outside the EEZ
Consistent with the VGP and USCG regulations at 33 CFR 151.2015,
the final rule exempts from the numeric ballast water discharge
standard vessels that are less than or equal to 3,000 GT (1,600 GRT if
GT is not assigned) and that do not operate outside the EEZ. 40 CFR
139.10(d)(3)(i). This includes both seagoing and non-seagoing vessels.
EPA bases this exemption on the finding that ballast water technologies
are not available or economically achievable for this universe of
smaller vessels (e.g., tugboats). BWMSs generally have been designed
for larger vessels or vessels that only uptake or discharge ballast
water on either end of longer voyages. EPA considered whether a
different threshold in terms of size should be used; however, EPA did
not identify, nor did commenters provide, information suggesting a
different threshold would be appropriate. Therefore, EPA continues to
conclude in this final rule that a numeric ballast water discharge
standard is infeasible and that the BMPs imposed constitute BAT
(requires this class of vessels to minimize the discharge of pollutants
in ballast water through BMPs only).
ii. Vessels That Are Non-Seagoing, Unmanned, Unpowered Barges
The final rule exempts from the numeric ballast water discharge
standard any non-seagoing, unmanned, unpowered barge that is not part
of a dedicated vessel combination. 40 CFR 139.10(d)(3)(ii). A dedicated
vessel combination includes an integrated or articulated tug barge
(ATB) unit consisting of two separate vessels that operate in tandem,
always together. The VGP, in Part 2.2.3.5.3.2, exempted all unmanned,
unpowered barges from compliance with the numeric ballast water
discharge standard; however, the USCG regulations at 33 CFR 151.2015
did not exempt any seagoing vessel 3,000 GT (1,600 GRT if GT is not
assigned) and above or that operates outside of the EEZ.
The record indicates that an unmanned, unpowered barge, when part
of a dedicated vessel combination, can install a BWMS as may be
necessary to meet the discharge standard. As such, EPA is clarifying
that these dedicated vessel combinations, even when they include an
unmanned, unpowered barge component, are not exempt from compliance
with the numeric ballast water discharge standard.
Most unmanned, unpowered barges operate in internal and coastal
waterways (i.e., non-seagoing) to transport bulk items such as grain,
coal, and iron ore. These vessels have no onboard crew and do not have
infrastructure that allows for complex or energy intensive operations.
EPA understands that ballasting for some of
[[Page 82101]]
these barges is performed in limited instances, such as to pass under
bridges or to improve stability in bad weather or other rough water.
These barges typically do not have dedicated ballast tanks but can use
wing tanks (void space) in the hull when ballasting is necessary. As
such, minimal water is used for ballasting.
Unmanned, unpowered barges have been recognized as experiencing
unique challenges for managing ballast water. For instance, EPA's
Science Advisory Board (SAB) notes: ``Inland waterways and coastal
barges are not self-propelled, but rather are moved by towing or
pushing with tugboats. Because these vessels have been designed to
transport bulk cargo, or as working platforms, they commonly use
ballast tanks or fill cargo spaces with water for trim and stability,
or to prevent excessive motions in heavy seas. However, the application
of [ballast water management systems] on these vessels presents
significant logistical challenges because they typically do not have
their own source of power or ballast pumps and are unmanned.'' (U.S.
EPA, 2011b). Therefore, the final rule requires this class of vessels
to minimize the discharge of pollutants in ballast water through BMPs
only.
iii. Vessels That Uptake and Discharge Ballast Water Exclusively in the
Contiguous Portions of a Single COTP Zone
Consistent with the VGP and USCG regulations at 33 CFR 151.2015(c)
and (d)(3), the final rule exempts from the numeric ballast water
discharge standard vessels that uptake and discharge ballast water
exclusively in a single Captain of the Port Zone (COTP) Zone, but that
may operate in more than one COTP Zone. 40 CFR 139.10(d)(3)(iii). The
rule, as proposed and finalized, clarifies that this exemption applies
within the contiguous portion of any single COTP Zone. EPA added the
term ``contiguous portions'' of a single COTP Zone, consistent with its
use in the VIDA (See 33 U.S.C. 1322(p)(6)(B)(ii)(II)(bb)), to clarify
that the exemption applies to ballasting and deballasting operations
within a single COTP Zone spanning contiguous waters within the
Exclusive Economic Zone (EEZ) and does not apply in those instances
when a COTP Zone includes areas that are not within a single bounded
EEZ. For example, in the Pacific Region, Sector Honolulu covers all of
the Hawaiian Island chain, American Samoa, Wake Island, and other
widely dispersed areas in the Pacific Ocean that in certain instances
require vessels to leave the EEZ to travel from one location to
another, all within the same COTP Zone.
This exemption is consistent with requirements of the VGP.
Additionally, it recognizes that ensuring that the operations of these
vessels remain within a single COTP zone is highly effective and the
best available technology for minimizing the introduction and spread of
ANS from vessel discharge because organisms discharged in their ballast
water are unlikely to be foreign and invasive. This exemption does not
apply to the ballast water BMPs for these vessels to ensure that
ballast water is managed appropriately.
iv. Vessels That Travel No More Than 10 Nautical Miles and Do Not Pass
Through Any Locks During Their Voyages
Consistent with the VGP, the final rule exempts from the numeric
ballast water discharge standard vessels that travel no more than 10 NM
and do not pass through any locks during their voyages. 40 CFR
139.10(d)(3)(iv). These vessels (e.g., cross-river ferries) contribute
insignificantly to the introduction and dispersal of ANS; however, the
implementation of BMPs for these short-voyage vessels is intended to
minimize the contribution of ANS that the vessels could cumulatively
have in a region. Exempting these vessels also helps minimize other
non-water quality environmental impacts, a consideration for setting
technology-based standards (See 40 CFR 125.3(d)(3)) that may result
from the operation of BWMSs, including increased energy usage and
increased carbon emissions. Further, many existing BWMSs use biocides
that require a minimum contact time to be effective. Short distance
voyages may not provide the time necessary for biocides to be
effective. In fact, the discharge of ballast water treated with
biocides may contain residuals or byproducts from that treatment, and
short voyage times may not permit adequate decay or neutralization.
v. Vessels That Operate Exclusively in the Laurentian Great Lakes
The final rule exempts all Lakers from the numeric ballast water
discharge standard. 40 CFR 139.10(d)(3)(vi). As required by the VIDA,
EPA assessed whether a technology exists that is technologically
available and economically achievable. EPA determined that the ballast
water numeric standard for the Lakers is infeasible because the same
challenges that were identified and analyzed in the VGP remain true
today. EPA has decided to retain the VGP's exemption for Lakers from
the numeric ballast water discharge standard. Specifically, this
exemption is based on a set of unique circumstances, as described in
the proposed rule at section VIII.B.1.vi.E, Vessels that Operate
Exclusively in the Laurentian Great Lakes (85 FR 67854, October 26,
2020), including issues related to the unique nature of the waters of
the Great Lakes, including extremely low salinity and high levels of
suspended solids, turbidity, icing, filamentous bacteria, and dissolved
organic carbon from tannins and humic acid. These environmental
conditions can clog filters and inhibit BWMS treatment effectiveness
and pose unique challenges to Lakers because, unlike other vessels
operating in challenging water conditions, Lakers cannot leave the
Great Lakes and thus do not have the option to perform a ballast water
exchange and saltwater flush under more favorable conditions. In
addition, the operational profile (e.g., short voyages) and design of
these freshwater vessels (e.g., uncoated ballast tanks and piping
systems that cannot withstand corrosive ballast water treatment
chemicals) are not conducive to certain BWMSs.
EPA acknowledges that this exemption is less stringent than the
VGP; however, consistent with CWA section 312(p)(4)(D)(ii)(II), the
Administrator may revise a standard of performance to be less stringent
than an applicable existing requirement if the Administrator determines
that a material technical mistake occurred or if information becomes
available that was not reasonably available when the Administrator
promulgated the initial standard of performance. EPA has concluded that
it made such a material technical mistake in the VGP when it determined
that the environmental conditions and operational limitations
identified as the basis for excluding Lakers constructed prior to 2009
from the numeric ballast water discharge standard would not be a
limiting factor for those constructed after 2009. Additionally, the
universe of post-2009 Lakers subject to the VGP numeric ballast water
discharge standard is all operating under a USCG compliance date
extension. Those extensions, granted in accordance with 33 CFR
151.2036, are in lieu of practical implementation of the numeric
discharge standard in 33 CFR 151.1511, and are based on a USCG
determination that Lakers are subject to unique
[[Page 82102]]
challenges affected by vessel operations and system limitations.
The proposed rule identified four more limited, alternative
regulatory BMP options for Lakers, including: (1) require installation,
operation, and maintenance of a USCG type-approved BWMS as an equipment
standard; (2) require filtration only; (3) require open lake exchange
of highly turbid water taken up in river ports; and (4) exempt the use
of a BWMS for certain voyages when the operational parameters of an
installed BWMS cannot be met.
As described in section VIII.B.1.d.vii of this preamble, New Laker
Equipment Standard, EPA did establish an equipment standard as a
ballast water BMP, for any new Laker, as defined in this final rule, to
install, operate, and maintain a BWMS that has been type-approved by
the USCG. However, EPA does not have adequate data to demonstrate the
engineering aspects for the application of the other three alternative
technologies or practices to reduce discharges of organisms. As
described in section VIII.B.1.d.vii of this preamble, New Laker
Equipment Standard, consistent with section 903(g) of the VIDA, EPA
established the Great Lakes and Lake Champlain Invasive Species Program
in part to develop solutions for such issues for ballast water
discharges from Lakers.
Because the Laker fleet represents a very small percentage of the
worldwide market, limited time and resources have been devoted to
advance BWMSs for Lakers or demonstrate that these systems work onboard
Lakers. As a result, Laker owners have no alternative in selecting a
commercially available system that would achieve the numeric ballast
water discharge standard. EPA's research program is a collaborative
strategy intended to drive the market for this technology given the
small number of vessels.
Under CWA section 312(p)(4)(D)(i), EPA must review its discharge
standards at least every five years and revise the standards as
appropriate. If data and information become available that can be used
to identify additional BAT approaches for Lakers, whether it is
installation of technology or implementation of additional BMPs, EPA
can propose updates to the discharge standard to reflect new BAT-based
requirements in advance of the five-year review date. Such an update
may address the entire universe of vessels that operate exclusively on
the Great Lakes, or reasonably could consider the appropriateness of
the identified technology or practices to the different segments of the
Great Lakes fleet, such as among classes, types, and sizes and between
new and existing vessels as provided for under the VIDA. EPA expects
that the ballast water management research and development activities
described under the Great Lakes and Lake Champlain Invasive Species
Program may provide a sound basis for proposing new or updated
standards in the future.
Notwithstanding EPA's determination that, in the context of a
technology-based standard, it is appropriate to exempt all Lakers from
the numeric ballast water discharge standard, Congress also created a
role under the VIDA for states to promulgate enhanced Great Lakes
requirements by enacting a process, codified in CWA section
312(p)(10)(B), in which Governors of the Great Lakes states can work
together to develop an enhanced standard of performance or other
requirements with respect to any incidental discharge, including
ballast water. In all cases where Great Lakes Governors petition for an
enhanced requirement, EPA and USCG may only reject the proposed
requirement if it is less stringent than existing standards or
requirements under this section, inconsistent with maritime safety, or
inconsistent with applicable maritime and navigation laws and
regulations. The procedures for such a petition are identified in this
rule at 40 CFR 139.51.
vi. Vessels in the USCG Shipboard Technology Evaluation Program (STEP)
Consistent with the VGP and USCG regulations at 33 CFR part 151
subpart D, the final rule exempts from the numeric ballast water
discharge standard any vessel equipped with ballast tanks if that
vessel is enrolled by the USCG in the Shipboard Technology Evaluation
Program (STEP). 40 CFR 139.10(d)(3)(vii). The STEP will continue to
play a critical role in the development of effective BWMSs, as with
many other related or similar programs the USCG might implement in the
future. The program has encouraged pioneering vessel operators to
install BWMSs, contributed to the development of effective sampling
methods, and allowed for the collection of valuable shipboard ballast
water treatment data needed to evaluate the efficacy of BWMSs.
Furthermore, the STEP is a venue for treatment vendors to develop and
refine systems that comply with the numeric ballast water discharge
standard and can be successfully approved through the USCG type-
approval process, resulting in the availability of a greater range of
systems for vessel owners. Vessels involved in the STEP use ballast
water treatment technologies that share similarities in capabilities
(and in many cases, are the same systems) as those described in the
technical reports EPA used to inform the final rule. Therefore, the
final rule exempts these vessels from meeting the numeric ballast water
discharge standard as they are effectively using treatments systems
that reflect BAT. Additionally, it would not be practicable for these
vessels to simultaneously fulfill their purpose of testing BWMS to
determine their effectiveness at meeting discharge standards while
simultaneously requiring them to meet those discharge standards at all
times.
vii. Vessels Discharging Ballast Water in the Same Location
Based on new information received in comments on the proposed rule,
the final rule includes an additional exemption from the numeric
ballast water discharge standard for discharges of ballast water at the
same location where that ballast water originated, provided that no
mixing with unmanaged ballast water and/or sediment from other areas
has occurred. 40 CFR 139.10(d)(3)(v). Because such single-location
ballast water by its nature could not be introducing ANS or other
pollutants, EPA's view is that imposing numeric standards on this type
of ballast water would not result in a greater level of pollution
control. This exemption is consistent with the IMO BWM Convention
Regulation A-3.5. If mixing has occurred, the ballast water taken from
other areas is subject to the numeric ballast water discharge standard.
This exemption is being added largely to allow for the practical
reality of the operation of certain vessels, such as semi-submersible
vessels, and how ballast water is used on such vessels. This exemption
allows a vessel to discharge ballast water made up of managed ballast
water from any location with unmanaged ballast water taken up and
discharged in a single location. The residual ballast water transported
between COTP Zones is subject to the numeric ballast water discharge
standards and all ballast water BMPs apply. Specific ballast tank
management requirements for vessels traveling between two COTP Zones
and qualifying for this exemption would fall under the USCG's
implementing regulations established under CWA section 312(p)(5).
viii. Discharges Prior to the Ballast Water Discharge Standard
Compliance Date
The final rule includes an exemption providing that the ballast
water discharge standard does not apply until
[[Page 82103]]
a given vessel's compliance date established pursuant to USCG
regulations. 40 CFR 139.10(d)(3)(viii). This exemption is consistent
with existing USCG procedures to address instances where the master,
owner, operator, agent, or person in charge of a vessel can document
that, despite all efforts, compliance with the numeric ballast water
discharge standard is not possible. This exemption is also consistent
with the VGP, where EPA acknowledged these procedures in its
Enforcement Response Policy for EPA's 2013 Vessel General Permit:
Ballast Water Discharges and U.S. Coast Guard Extensions under 33 CFR
part 151, December 27, 2013 (U.S. EPA, 2013) whereby EPA would consider
vessels operating under a Coast Guard extension letter pursuant to 33
CFR 151.2036 a low enforcement priority under the VGP.
g. Numeric Ballast Water Discharge Standard Compliance Dates
The final rule does not include compliance dates for the numeric
ballast water discharge standard; rather, EPA expects the USCG to
include such as part of its implementation, compliance, and enforcement
rulemaking pursuant to CWA section 312(p)(5). EPA acknowledges and
supports continuation of USCG procedures to address those cases where
the master, owner, operator, agent, or person in charge of a vessel can
document that, despite all efforts, compliance with the numeric ballast
water discharge standard is not possible. The details of such vessel-
specific requests would fall under the USCG's implementing regulations.
For perspective, the existing USCG review considers safety and
regulatory requirements of electrical equipment, vessel capacity to
accommodate BWMS, vessel age, shipyard availability, or other similar
factors and allowances are granted for no longer than the minimum time
needed, as determined by the USCG, for the vessel to comply with the
numeric ballast water discharge standard.
h. Ballast Water Exchange and Saltwater Flush
The final rule requires vessel operators to conduct a ballast water
exchange or saltwater flush in certain instances. 40 CFR 139.10(e). The
final rule codifies definitions of ``ballast water exchange,''
``saltwater flush,'' and ``empty ballast tank'' from CWA section
312(p)(1) as these terms are used within the context of this section.
40 CFR 139.2.
The final rule, consistent with the provision in CWA section
312(p)(4)(B)(iii) that the requirements be no less stringent than the
VGP, continues the interim ballast water management requirement for
vessel operators, unless otherwise excepted from the requirement, to
conduct ballast water exchange in lieu of treating ballast water prior
to a vessel's compliance date for meeting the numeric ballast water
discharge standard. 40 CFR 139.10(e). The interim ballast water
exchange requirements in the final rule specify that before entering
waters of the United States or waters of the contiguous zone, any
vessel operating beyond the EEZ and with ballast water onboard that was
taken within 200 NM of any shore must either meet the numeric discharge
standard or conduct a midocean exchange further than 200 NM from any
shore prior to discharging that ballast water in waters of the United
States or waters of the contiguous zone. The exchange must occur as
early as practicable in the voyage, so long as the exchange occurs more
than 200 NM from shore. 40 CFR 139.10(e)(1). This requirement reduces
the likelihood of the spread of ANS, prior to a numeric ballast water
discharge standard compliance date, by increasing the mortality of
living organisms in ballast tanks and ensuring that the discharge
contains fewer viable living organisms.
The final rule, as directed by CWA section 312(p)(6)(B), expands
ballast water exchange and saltwater flush requirements beyond those in
the VGP and USCG regulations. Specifically, the final rule requires
that vessels with empty ballast tanks bound for a port or place of
destination subject to the jurisdiction of the United States shall,
prior to arriving at that port or place of destination, conduct a
ballast water exchange or saltwater flush of empty ballast tanks that
carry unpumpable ballast water and residual sediments (or otherwise
seal the tank so that there is no discharge or uptake and subsequent
discharge of ballast water). Also, ballast water exchange or saltwater
flush must occur no less than 200 NM from any shore for a voyage
originating outside the United States or Canadian EEZ, or no less than
50 NM from any shore for a voyage originating within the United States
or Canadian EEZ. 40 CFR 139.10(e)(2).
EPA notes that these saltwater flush requirements reflect a widely
used, low-cost preventative approach that minimizes the risk that ANS
will be introduced from unpumpable ballast water and residual sediment.
A saltwater flush is most effective at eliminating organisms adapted to
freshwater and low salinity environments due to the combined impacts of
saltwater shock and physical dilution. However, a saltwater flush
should also reduce viable living organisms adapted to estuarine,
coastal, and marine environments. A saltwater flush reduces viable
living organisms in residual ballast water through dilution. It also
reduces organisms in resting stages in the residual sediment. Resting
stages of organisms often inhabit the sediment in ballast tanks; thus,
a reduction in the number of these organisms will likely reduce the
propagule of potential invaders.
The final rule incorporates from CWA section 312(p)(6)(B)(ii)
certain exceptions to the ballast water exchange or saltwater flush
requirements for empty tanks, including: if the unpumpable residual
waters and sediments of an empty ballast tank were treated by a USCG
type-approved BWMS; except as otherwise required under this part, if
the unpumpable residual waters or sediments of an empty ballast tank
were sourced within the same port or place of destination or sourced
within the contiguous portions of a single COTP Zone; if complying with
an applicable requirement would compromise the safety of the vessel or
is otherwise prohibited by any Federal, Canadian, or international law
(including regulations) pertaining to vessel safety; and if the vessel
is operating exclusively within the internal waters of the United
States or Canada. 40 CFR 139.10(e)(3).
CWA section 312(p)(6)(B)(ii)(IV) includes one additional exception
to the ballast water exchange or saltwater flush requirement: ``if
design limitations of the vessel prevent a ballast water exchange or
saltwater flush from being conducted'' in accordance with applicable
requirements. The final rule at 40 CFR 139.10(e)(3)(iv) largely
incorporates this exclusion but, consistent with the proposed rule,
limits its applicability only to existing vessels, defined as a vessel
constructed prior to the date identified in the forthcoming USCG
implementing regulations as described in 40 CFR 139.1(e). EPA
interprets the ``design limitation'' exclusion in the VIDA to apply
only to existing vessels since the VIDA added permanent exchange
requirements, presumably because of the added benefit in performing
such an exchange. If the design exclusion applied to new vessels, it
would undermine the purpose of the statutory ballast water exchange and
saltwater flush requirements by disincentivizing the design and
construction of new vessels that are capable of conducting an exchange
or flush. It is critical that new vessels have the capability to
conduct
[[Page 82104]]
ballast water exchange and a saltwater flush, even if they install a
BWMS, particularly as a contingency measure if the treatment system
fails to operate as expected. The VGP included an additional exception,
except for vessels entering the Great Lakes or in federally- protected
waters, for a vessel to not be required to deviate from its voyage, or
delay the voyage to conduct a ballast water exchange or saltwater
flush. However, CWA section 312(p)(6)(B)(ii) did not include such an
exemption and as such the final rule does not allow this route
deviation or delay exemption to the final rule's requirements
implementing CWA section 312(p)(6)(B)(i).
i. Vessels Entering the Great Lakes
The final rule requires, based on CWA section 312(p)(10)(A),
vessels entering the St. Lawrence Seaway through the mouth of the St.
Lawrence River to conduct a complete ballast water exchange or
saltwater flush (as appropriate) not less than 200 NM from any shore
for a voyage originating outside the EEZ; or not less than 50 NM from
any shore for a voyage originating within the EEZ. 40 CFR 139.10(f)(1).
There are exceptions to these requirements, including if: the vessel
has no residual ballast water or sediments onboard to the satisfaction
of the USCG; empty tanks are sealed; or ballast water is retained
onboard while operating in the Great Lakes. 40 CFR 139.10(f)(2)(iii)
through (v). Consistent with the VGP and the VIDA's text, the final
rule does not contain an exception for vessels that use a BWMS to treat
the ballast water prior to discharge.
Part 2.2.3.7 of the VGP required vessels that operate outside the
EEZ and more than 200 NM from any shore and then enter the Great Lakes
through the St. Lawrence Seaway to conduct ballast water exchange or a
saltwater flush in addition to treatment, if ballast water uptake
occurred within the previous 30 days from a coastal, estuarine, or
freshwater ecosystem with a salinity of less than 18 parts per
thousand. EPA determined that this requirement of the VGP is not
necessary to include in the final rule given that the VIDA statutory
requirement is more restrictive than (and supersedes) that VGP
requirement.
Consistent with the VIDA, the final rule expands the requirement
for exchange or a saltwater flush plus treatment for vessels entering
the Great Lakes through the St. Lawrence River to a larger universe of
vessels, as compared to the VGP requirements and USCG regulations found
at 33 CFR part 151. Specifically, the final rule at 40 CFR 139.10(f)(1)
extends the exchange and saltwater flush requirements to ``any
vessel,'' while the VGP and USCG requirements limited these
requirements to vessels operating outside the EEZ and more than 200 nm
from any shore and having taken on ballast water with a salinity of
less than 18 parts per thousand within the previous 30 days. In 2014
and 2015, a total of 81 unique vessels arrived at U.S. ports in the
Great Lakes from oversees on 131 voyages. Most of these voyages
departed from European ports (82 percent). However, there are limited
data on the salinity of the origination ports. Therefore, it is
difficult to estimate the affected universe from higher salinity ports
that are now required to do exchange plus treatment. However, many of
these vessels may have been conducting exchange plus treatment prior to
the compliance dates for these vessels to install a BWMS, to ensure
compliance with the VGP. Consequently, there may be minimal impact on
these vessels, and the requirement are expected to be technologically
available and economically achievable for these vessels.
Existing USCG regulations at 33 CFR 151.1502 require that vessels,
after operating on the waters beyond the EEZ during any part of their
voyage, that enter through the St. Lawrence Seaway or that navigate
north of the George Washington Bridge on the Hudson River, perform a
ballast water exchange or saltwater flush regardless of other port
calls in the United States or Canada during that voyage, except as
expressly provided in 33 CFR 151.2015(a). In the final rule, EPA does
not specifically identify this universe of vessels as having to perform
a ballast water exchange or saltwater flush prior to entering the
Hudson River or St. Lawrence Seaway, unless the vessel is meeting the
numeric ballast water discharge standard (e.g., has installed and is
operating a USCG type-approved BWMS), as the final rule requires such
ballast water exchange or saltwater flush for any vessels subject to
the ballast water discharge standard. Therefore, while the final rule
does not call out this universe of vessels specifically, similar
requirements are being finalized for these and a larger universe of
vessels.
Consistent with the CWA section 312(p)(10)(A)(ii)(I), the final
rule includes exceptions to ballast water exchange or saltwater flush
requirements for vessels entering the Great Lakes, if: (1) compliance
would compromise the safety of the vessel; (2) compliance is otherwise
prohibited by any Federal, Canadian, or international law (including
regulations) pertaining to vessel safety; or (3) design limitations of
an existing vessel prevent a ballast water exchange from being
conducted. 40 CFR 139.10(f)(2)(i) and (ii). As described in section
VIII.B.1.h. of this preamble, Ballast Water Exchange and Saltwater
Flush, the final rule adds a limitation to the design exclusion to
apply only to existing vessels, defined as a vessel constructed prior
to the date identified in the forthcoming USCG implementing
regulations, as described in 40 CFR 139.1(e). This limitation is
important to prevent the design and construction of new vessels that
cannot conduct an exchange or flush. It is critical that new vessels
entering the Great Lakes have this capability, even if they install a
BWMS, particularly as a contingency measure if the treatment system
fails to operate as expected.
j. Pacific Region
The VIDA establishes more stringent Pacific Region requirements for
ballast water exchange than were required under the VGP. The final rule
requires, as dictated by CWA section 312(p)(10)(C), that any vessel
that operates either between two ports within the U.S. Pacific Region
or between ports in the Pacific Region and the Canadian or Mexican
Pacific Coast north of parallel 20 degrees north latitude, inclusive of
the Gulf of California, conduct a complete ballast water exchange in
waters more than 50 NM from shore. 40 CFR 139.10(g)(1). The term
``Pacific Region'' includes the entire EEZ adjacent to the states of
Alaska, California, Hawaii, Oregon, and Washington. 33 U.S.C.
1322(p)(1)(S). There are exceptions in the VIDA to these exchange
requirements, including if the vessel is using a type-approved BWMS or
for voyages between or to specific ports in the states of Washington,
Oregon, California, Alaska, and Hawaii, and the Port of Los Angeles,
the Port of Long Beach, and the El Segundo offshore marine oil
terminal, if the ballast water originated from specified areas. 33
U.S.C. 1322(p)(10)(C)(ii)(II).
As specified in the VIDA, and codified in 40 CFR 139.10(g)(2), the
final rule requires that any vessel that transports ballast water
sourced from low salinity waters (less than 18 parts per thousand) and
voyages to a Pacific Region port or place of destination with low
salinity must conduct a complete ballast water exchange. The exchange
must occur not less than 50 NM from shore, if the ballast water was
sourced from a Pacific Region port; or more than 200 NM from shore, if
the ballast water was not sourced from a Pacific Region port. These
exchange requirements do
[[Page 82105]]
not apply to any vessel voyaging to the Pacific Region that is using a
type-approved BWMS that achieves standards of performance for low
salinity water that are more stringent than the existing VGP and USCG
numeric ballast water discharge standards. The low salinity water
standards of performance as specified in CWA section
312(p)(10)(C)(iii)(II) are:
Less than 1 organism per 10 cubic meters, if that organism
(1) is living or has not been rendered nonviable; and (2) is 50 or more
micrometers in minimum dimension;
Less than 1 organism per 10 milliliters, if that organism
(1) is living or has not been rendered nonviable; and (2) is more than
10, but less than 50, micrometers in minimum dimension; and
Concentrations of indicator microbes that are less than
(1) 1 colony-forming unit of toxicogenic Vibrio cholerae (serotypes O1
and O139) per 100 milliliters or less than 1 colony-forming unit of
that microbe per gram of wet weight of zoological samples; (2) 126
colony-forming units of Escherichia coli per 100 milliliters; and (3)
33 colony-forming units of intestinal enterococci per 100 milliliters.
The final rule corrects a typographical error from the proposed
rule regulatory text that indicated a discharge standard of less than 1
organism per 100 milliliters (rather than the correct value of 1
organism per 10 milliliters) for organisms more than 10, but less than
50, micrometers in minimum dimension. The proposed rule preamble text
reflected the correct value, which is carried forward into this final
rule.
As established by the VIDA, the final rule at 40 CFR 139.10(g)(3)
exempts vessels from the Pacific Region requirements if any of the
following conditions exist: (1) compliance would compromise the safety
of the vessel; (2) design limitations of an existing vessel prevent a
ballast water exchange from being conducted; (3) the vessel has no
residual ballast water or sediments onboard to the satisfaction of the
Secretary, or the vessel retains all ballast water while in waters
subject to the requirement; or (4) empty ballast tanks on the vessel
are sealed in a manner that ensures that no discharge or uptake occurs
and that any subsequent discharge of ballast water is subject to the
requirement. As described in the previous ballast water exchange
sections, the final rule limits the design exclusion only to existing
vessels, defined as a vessel constructed prior to the date identified
in the forthcoming USCG implementing regulations, as described in 40
CFR 139.1(e) and only as determined by the USCG. This limitation is
important to prevent the design and construction of new vessels that
cannot conduct an exchange or flush as an alternative ballast water
management option for those instances when, for example, an installed
BWMS fails to operate as expected.
As compared to the VGP, the VIDA expanded requirements for the
Pacific Region to include exchange or more stringent treatment for low
salinity waters. Except for any vessel that transports low salinity
ballast water (less than 18 ppt) and voyages to a low salinity Pacific
Region port or place of destination, the final rule requirement to
conduct ballast water exchange in the Pacific Region is an interim
requirement until a vessel installs a type-approved BWMS that meets the
ballast water discharge standard. As specified in CWA section
312(p)(10)(C)(iii), any vessel that transports low salinity ballast
water (less than 18 ppt) and voyages to a low salinity Pacific Region
port or place of destination must continue to conduct a complete
ballast water exchange, unless it has installed a type-approved BWMS
that achieves standards of performance, depending on the parameter, up
to 100 times more stringent than the existing discharge standard. Id.
(p)(10)(C)(iii)(II). Currently, there is not a USCG type-approval
process for BWMSs to demonstrate the ability to achieve this more
stringent standard. Therefore, vessels from low salinity waters must
continue to conduct exchange until such a process is developed and
BWMSs are approved to meet that more stringent standard.
For the most part, the continental shelf along the Pacific coast is
narrow along both North and South America. Deep water environments
beyond the continental shelf typically support ecosystems that are
quite different than those which exist closer to shore. Due in part to
the narrow width of the continental shelf and relatively deep waters
beyond 50 NM from the Pacific shore, exchange at this distance from the
Pacific shore will be effective.
In addition, the VIDA described the applicability of the Pacific
Region exchange requirements differently as compared to the VGP. The
final rule implements the VIDA requirements as established by Congress
in the statute rather than as written in the VGP. The VGP required
exchange for vessels on nearshore voyages that carry ballast water
taken on in areas less than 50 NM from any shore. It defined nearshore
voyages as those vessels engaged in coastwise trade along the U.S.
Pacific coast operating in and between ports in Alaska, California,
Oregon, and Washington that travel between more than one COTP Zone. The
VIDA did not include the stipulation that a vessel voyage must be
between more than one COTP Zone. In addition, the VIDA includes vessels
operating in ports in the State of Hawaii, with certain exceptions, in
the exchange requirements that the VGP did not include. The VGP
required exchange for all other vessels that sail from foreign, non-
U.S. Pacific, Atlantic (including the Caribbean Sea), or Gulf of Mexico
ports, that do not sail further than 200 NM from any shore, and that
discharge or will discharge ballast water into the territorial sea or
inland waters of Alaska or off the west coast of the continental United
States. The VIDA did not identify nearshore voyages from outside of the
Pacific Region EEZ (although it did include parts of Canada and Mexico)
as being required to conduct exchange.
2. Bilges
Bilgewater consists of water and pollutant residues, such as oil,
grease, and metals, that accumulate in the vessel's bilge (the lowest
compartment of the vessel). The source of bilgewater is typically
drainage from interior machinery, engine rooms, pipes, and decks.
Bilgewater contains both conventional and toxic pollutants including
oil, grease, volatile and semi-volatile organic compounds, inorganic
salts, and metals. Volumes vary with the size of the vessel and
discharges typically occur several times per week. Cruise ships have
been estimated to generate 25,000 gallons of bilgewater per week for a
3,000 passenger/crew vessel (U.S. EPA, 2008). Bilgewater treatment
technologies can be used to remove pollutants from bilgewater. For
example, ultrafiltration can be effective in removing turbidity and
suspended solids, organic carbon, and several trace metals (such as
aluminum, iron, and zinc) from bilgewater, in addition to oil
(Tomaszewska et al., 2005).
Under MARPOL Annex I, all ships of 400 GT and above are required to
have equipment installed onboard that limits the discharge of oil to
less than 15 parts per million (ppm) when a ship is underway. All
vessels of 400 GT and above are also required to have an oil content
monitor (OCM), including a bilge alarm, integrated into the piping
system. In the United States, MARPOL is primarily implemented by APPS
(33 U.S.C. 1901 et seq.). The USCG's implementing regulations for APPS
are primarily found at 33 CFR part 151 and prohibit ``any discharge of
oil or oily mixtures into the sea from a ship'' except when certain
conditions are met,
[[Page 82106]]
including a discharge oil content of less than 15 ppm and that the ship
operates oily water separating equipment, a bilge monitor, a bilge
alarm, or a combination thereof. Additional regulations found at 46 CFR
part 162 detail the approval procedures. Approval is based on testing
of manufacturer-supplied oil pollution control equipment by an
independent laboratory, in accordance with test conditions prescribed
by the USCG (33 CFR parts 155 and 157 and 46 CFR part 162).
Additionally, as appropriate, the discharge of bilgewater also must
comply with related requirements in 33 CFR part 151, 40 CFR part 110,
and 46 CFR part 162. Except as expressly provided, the final VIDA
regulations do not affect the applicability of these other Federal laws
to a vessel.
To develop the bilgewater standard, EPA considered whether
increased stringency for the numeric discharge standard for oil content
might have been appropriate and elected to request specific information
on the matter. Specifically, EPA sought information from commenters
regarding the availability of type-approved systems capable of meeting
a 5 ppm numeric discharge standard for oil, as well as the availability
and cost of OCMs that can accurately determine oil content at 5 ppm or
lower detection levels. The majority of commenters responding to these
queries indicated that systems capable of meeting a 5 ppm standard may
not be widely available or reliable once installed onboard. Concerns
regarding reliability were largely tied to OCM issues; namely, that
their functionality can easily be disrupted and that measurements often
differ from analytical results. Commenters were generally in agreement
that the existing 15 ppm standard under APPS regulations is appropriate
and that equipment is reliable to achieve this standard. None of the
comments received provided specific information about OCMs or their
cost. Because no information was provided by commenters that
affirmatively demonstrates the availability and affordability of
systems consistently and demonstrably meeting a 5 ppm standard, EPA is
not establishing any new enhanced system requirements. In the proposed
rule (85 FR 67818, October 26, 2020, section VIII.B.2.), EPA explained
that the VGP requirement for vessel operators to meet a discharge limit
for oil of 15 ppm or to not discharge oil in quantities that may be
harmful was consistent with the proposed general discharge standards
for oil management. EPA also did not want to be redundant to existing
requirements under the APPS. As such, the proposed rule did not
explicitly identify the 15 ppm oil content limit in the proposed bilges
regulations, despite discussing this limit at length in the preamble.
However, one commenter expressed confusion that the numeric limit from
the VGP was missing. Based on its consideration of comments, EPA
determined that it is appropriate and clearer to include the 15 ppm
directly in the regulatory standard. This approach is consistent with
the VGP and existing regulations and, as discussed in the preambles of
both the proposed rule and this final rule, EPA determined that
available systems are capable of meeting this numeric standard and it
is an existing practice. Therefore, 40 CFR 139.11(c) requires that the
oil content of any bilgewater discharges from any vessel of 400 GT and
above must not exceed 15 ppm.
The final rule at 40 CFR 139.11 maintains the same requirements
included in the proposed rule and includes one additional requirement
based on comments received during the public comment period. Consistent
with the proposed rule, the final rule incudes both general and
specific standards for bilgewater, detailed in 40 CFR part 139,
subparts B and C, respectively. The general standards require vessels
to minimize discharges and prohibit the discharge of oil in such
quantities as may be harmful. The specific standards in the final rule
require that the discharge of bilgewater must not contain any
flocculants or other additives except when used with an oily water
separator or to maintain or clean equipment. The use of any additives
to remove the appearance of a visible sheen is also prohibited. 40 CFR
139.11(b).
EPA proposed to require all vessels of 400 GT and above to
discharge treated bilgewater when underway but allowed such discharges
to occur any distance from shore, except in federally-protected waters.
The VGP, on the other hand, required vessels greater than 400 GT that
regularly sail outside the territorial sea (i.e., at least once per
month) to discharge treated bilgewater while underway and, if
technologically feasible, at least 1 NM from shore (emphases added).
EPA retained the requirement to discharge while underway, as
discharging while underway is advantageous because it promotes dilution
of the discharge and should be available to all vessels of 400 GT and
above. EPA proposed, however, to broaden the applicability of the
requirement to all vessels of 400 GT and above, and not just those
vessels greater than 400 GT that regularly sail outside the territorial
sea. EPA proposed this new approach because it learned that the VGP
requirement was difficult to implement and led to confusion about
whether and when a vessel may be authorized to discharge treated
bilgewater when not underway, particularly as it related to determining
when a vessel would be considered to ``regularly'' sail outside the
territorial sea. While EPA proposed to remove the discharge prohibition
within 1 NM, commenters disagreed with its removal and EPA has
concluded that the Agency does not have a basis for being less
stringent than the VGP in this case that would be consistent with the
exceptions laid out in CWA section 312(p)(4)(D)(ii)(II). As such, the
final rule requires that bilgewater discharges from any vessel of 400
GT and above occur when the vessel is underway with an oil content that
does not exceed 15 ppm and, if technologically feasible, at least 1 NM
from shore. 40 CFR 139.11(c). Such vessels have the capability, in
terms of process and engineering, to adjust the timing and location of
bilgewater discharges and EPA does not expect this approach to impose
any significant additional cost burden as some vessels were subject to
this requirement under the VGP. Additionally, EPA found that more than
99.7 percent of vessels 400 GT and above did not discharge any
bilgewater under the VGP, based on information from the annual reports
for the 2019 operating year.
Finally, as noted above and as discussed in section VIII.C. of this
preamble, Discharges Incidental to the Normal Operation of a Vessel--
Federally-Protected Waters Requirements, the final rule requires
additional controls for bilgewater discharges from a vessel operating
in federally-protected waters. 40 CFR 139.40(c).
3. Boilers
Boiler blowdown is the discharge of water and constituents from the
boiler during regular intervals to avoid concentration of impurities
and at intermittent intervals for cleaning or other purposes. Boiler
blowdown occurs on vessels with steam propulsion or a steam generator
to control anti-corrosion and anti-scaling treatment concentrations and
to remove sludge from boiler systems. Routine blowdown involves
releasing a volume of about one to 10 percent of the water in the
boiler system to manage the accumulation of solids and buildup of
dissolved solids in the boiler water. Frequency of required blowdown
varies, typically between once every two weeks
[[Page 82107]]
to once every few months, although on some vessels blowdown may be as
frequent as daily or even continuously. The constituents of boiler
blowdown discharge vary according to the types of feed water treatment
used, but may include toxic pollutants such as antimony, arsenic,
cadmium, copper, chromium, lead, nickel, selenium, thallium, zinc, and
bis (2-ethylhexyl) phthalate.
EPA was unable to identify new technology or best management
practice options for discharges from boilers. Therefore, the Agency
relied on the BPT/BCT/BAT analysis underlying the VGP requirements, and
the fact that the VGP requirements are currently in effect, to require
substantively the same requirements included in the VGP. 40 CFR 139.12.
EPA did not receive any comments suggesting revisions to the proposed
requirements.
The final rule requires that the discharge of boiler blowdown be
minimized when in port. This requirement acknowledges that blowdown
typically must be performed as necessary and that while the amount of
blowdown can often be minimized, the timing of such blowdown, in many
instances, cannot be safely changed, such as to only those times when a
vessel is not in port. As such, this requirement is more specific to a
location (when in port) than the general operation and maintenance
requirements described in subpart B, for vessel operators to minimize
discharges of blowdown to only those times when necessary and to
discharge while the vessel is underway when practical and as far from
shore as practical. To comply with the requirements of the VGP, vessels
greater than 400 GT were adjusting the timing and location of blowdown
events. EPA has determined that all vessels subject to the rule can
similarly change the timing and location of their blowdown events as
necessary to minimize the discharge. This will reduce the discharge of
various pollutants but will not impose any significant additional cost
burden.
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule prohibits the discharge
of boiler blowdown into federally-protected waters. 40 CFR 139.40(d).
4. Cathodic Protection
Cathodic protection systems are used on vessels to prevent steel
hull or metal structure corrosion. The two types of cathodic protection
are galvanic (i.e., sacrificial anodes) and impressed current cathodic
protection (ICCP). Galvanic cathodic protection uses anodes, typically
made of magnesium, zinc, or aluminum, that are ``sacrificed'' to the
corrosive forces of the seawater, which creates a flow of electrons to
the cathode, thereby preventing the cathode (e.g., the hull) from
corroding. With ICCP, a direct current is passed through the hull such
that the electrochemical potential of the hull is sufficiently high to
prevent corrosion. The ICCP system releases oxidants during the
process, generally consisting of chlorinated and brominated substances
from the reaction with seawater. The discharge from either method of
cathodic protection is continuous when the vessel is waterborne.
However, galvanic protection discharges include both toxic and
nonconventional pollutants such as ionized zinc, magnesium, and
aluminum.
EPA was unable to identify new technology or best management
practice options for discharges resulting from cathodic protection,
therefore the Agency relied on the BPT/BCT/BAT analysis underlying the
VGP requirements and is requiring substantively the same requirements
included in the VGP with slight modification based on comments received
on the proposed standards. 40 CFR 139.13.
The final rule requires that any spaces between flush-fit anodes
and the backing must be filled, because niche areas on the hull are
more susceptible to biofouling and more difficult to clean.
Additionally, the general operation and maintenance requirements
described in subpart B require that any materials used onboard that are
subsequently discharged be used only in the amount necessary to perform
their intended function, including any sacrificial anodes. Therefore,
sacrificial anodes must not be used more than necessary to adequately
prevent corrosion of the vessel's hull, sea chest, rudder, and other
exposed vessel areas.
EPA proposed to not carry forward a requirement from the VGP
regarding the selection of sacrificial anode systems based on toxicity
of the anode, though the proposed rule preamble did note that the
Agency continues to support operators considering toxicity during
selection. As described in the preamble of the proposed rule (85 FR
67818, October 26, 2020, section VIII.B.4), EPA received new
information from its implementation of the VGP that this requirement
was not technologically feasible and/or economically practicable and
achievable in many instances. Based on a commenter's suggestion to
continue this concept through a BMP encouraging anode selection based
on toxicity, however, the final rule includes a requirement to consider
selection of anode materials based on toxicity of the base metal. 40
CFR 139.13(c). At the same time, the requirement to consider, but not
necessarily select, the least toxic metal acknowledges that the type of
anode metal selected based on toxicity (magnesium, then aluminum, then
zinc) may not be technologically feasible and/or economically
practicable and achievable in all instances. For example, in harbors or
estuaries with high pollutant loads, zinc is the preferred anode
material for vessels that spend time in those waters because of
concerns with pollutants causing aluminum anodes to passivate and lose
effectiveness.
EPA did consider requiring use of ICCP because these systems
eliminate or reduce the need for sacrificial anodes. However, there is
a risk of overprotecting using these systems (e.g., embrittlement in
high-strength vessels) or debonding of protective coatings, and these
systems generally should only be installed on vessels that are manned
full-time by a highly skilled crew able to carefully monitor and
maintain these systems. As such, the Agency recommends, but does not
require, that operators consider the use of ICCP in place of, or to
reduce the use of, sacrificial anodes when technologically feasible
(e.g., adequate power sources, appropriate for vessel hull size and
design), safe, and adequate to protect against corrosion, particularly
for new vessels.
5. Chain Lockers
Chain lockers are the storage area onboard for housing the vessel's
anchor and chain. Water, sediment, biofouling organisms, and
contaminants can enter and accumulate in the chain locker during anchor
retrieval and precipitation events. The accumulation of water and other
materials in the chain locker is often referred to as the chain locker
effluent. This effluent can contain both conventional and
nonconventional pollutants including biological organisms and residue
from the inside of the locker itself, such as rust, paint chips,
grease, and zinc. The sump collects these liquids and materials that
enter the chain locker prior to discharge or disposal.
EPA was unable to identify new technology or best management
practices options for discharges from chain lockers, therefore the
Agency relied on the BPT/BCT/BAT analysis underlying the VGP
requirements and is requiring substantively the same
[[Page 82108]]
requirements included in the VGP. 40 CFR 139.14.
The final rule requires that vessel operators implement BMPs that
would reduce or eliminate chain locker effluent discharge. Based on
comments received on the proposed rule, the final rule clarifies that
the chain locker requirements apply to accumulated biological organisms
and sediment in addition to precipitation and seawater, and that such
requirements are intended to prevent the discharge of accumulated
biological organisms, sediment, precipitation, and seawater when
deploying the anchor in a new port or place of destination. 40 CFR
139.14(a).
The final rule also requires that vessel operators rinse the anchor
chain of biofouling organisms and sediment when the anchor is
retrieved. 40 CFR 139.14(b). Additionally, the final rule prohibits the
discharge of biological organisms, sediment, precipitation, and
seawater from any chain locker when the vessel is in port. 40 CFR
139.14(c).
For all vessels that operate beyond the waters of the contiguous
zone, the final rule requires anchors and anchor chains to be rinsed of
biofouling organisms and sediment prior to entering the waters of the
contiguous zone. 40 CFR 139.14(d). This requirement is intended to
minimize the discharge of biofouling organisms when vessels that
operate beyond waters of the contiguous zone re-enter these waters and
subsequently drop anchor in waters of the United States or waters of
the contiguous zone. Based on comments received on the proposed rule,
the final rule at 40 CFR 139.14(d) clarifies that this requirement may
be satisfied by rinsing when the anchor is retrieved at the
commencement of the voyage or when the anchor was last retrieved on a
previous voyage, so long as the rinsing occurs after the last use of
the anchor beyond waters of the contiguous zone.
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule prohibits any discharge
of accumulated biofouling organisms, water, and sediment from any chain
locker into federally-protected waters. 40 CFR 139.40(e).
6. Decks
Deck discharges may result from deck runoff, deck washdown, or deck
flooding. Deck runoff consists of rain and other precipitation or
condensation, as well as freshwater and seawater, that sprays or washes
over the deck, well decks, and bulkhead areas. Deck washdowns consist
of cleaners and freshwater or saltwater. Deck flooding generally
consists of seawater from the flooding of a docking well (well deck) on
a vessel used to transport, load, and unload amphibious vessels, or
freshwater from washing the well deck and equipment and vessels stored
in the well deck. Deck washdown, runoff, and flooding discharges
include those from all deck and bulkhead areas and associated
equipment. The constituents and volumes vary widely depending on a
vessel's purpose and practices and may include both conventional and
nonconventional pollutants such as oil, grease, fuel, cleaner or
detergent residue, paint chips, paint droplets, and general debris.
Based on comments received on the proposed rule, the final rule
provides additional clarification on the list of deck discharges
identified in the proposed rule to also include condensation, seawater
spray and washover, flooding, and waters pumped from below deck on a
barge, all of which are also covered under this section per 40 CFR
139.15(a).
The final rule also includes a new requirement at 40 CFR 139.15(h),
consistent with Part 5.4.1. of the VGP, to clarify that barges which
discharge water pumped from below deck must minimize the contact of
below deck condensation with oily or toxic materials and any materials
containing hydrocarbon.
EPA was unable to identify new technology or best management
options for discharges from decks, therefore the Agency relied on the
BAT analysis underlying the VGP. 40 CFR 139.15. EPA received comments
requesting clarification on the proposed requirements for decks;
therefore, the final deck discharge standards are similar to the
proposed standards but include additional clarifications.
EPA determined that these BMPs are necessary to carry out the
intent of this subsection of the VIDA and because it is infeasible to
set a specific numeric discharge standard for discharges from decks and
well decks due to the variation in vessel size and associated deck
surface area, the types of equipment operated on the deck, limitations
on space for treatment equipment, as well as the nature of the
discharge. As such, the final rule includes BMPs to minimize the volume
of discharges and various pollutants from decks. The final rule
requires vessel operators to properly maintain the deck and bulkhead
areas to keep the deck clean; prevent excess corrosion, leaks, and
metal discharges; contain potential contaminants to keep them from
entering the waste stream; and use minimally toxic, phosphate-free, and
biodegradable products. Properly maintaining the deck includes the use
of coamings or drip pans for machinery on the deck that is expected to
leak or otherwise release oil, so that any accumulated oils from these
areas can be collected and managed appropriately per 40 CFR 139.15(b).
The final rule also requires that, prior to performing a deck
washdown and when underway, exposed decks must be kept broom clean to
remove existing debris and prevent the introduction of garbage or other
debris into any waste stream. 40 CFR 139.15(e). As defined in 40 CFR
139.2, ``broom clean'' means a condition in which the deck shows that
care has been taken to prevent or eliminate any visible concentration
of surface residues. In response to comments received on the proposed
rule, EPA is clarifying that broom cleaning is intended as a BMP to
address residues. Spills may be more appropriately addressed through
other BMPs in this section, such as coamings, drip pans, and other
control measures. See 40 CFR 139.15(b). Similarly, control measures
must be used to minimize the introduction of on-deck debris, garbage,
residue, spills, floating solids, visible foam, halogenated phenolic
compounds, dispersants, and surfactants into deck washdown and runoff.
40 CFR 139.15(d). During deck washdown, the final rule requires that
the washdown be conducted with minimally-toxic, phosphate-free, and
biodegradable soaps, cleaners, and detergents. 40 CFR 139.15(g). The
final rule also requires that discharges from deck washdowns be
minimized in port. 40 CFR 139.15(f). Lastly, the final rule requires
that, where applicable by an international treaty or convention or the
Secretary, a vessel must be fitted with and use physical barriers
(e.g., spill rails, scuppers, and scupper plugs) during any washdown to
collect runoff. 40 CFR 139.15(c). While applicable to any discharge
addressed in this rule, due to the nature of deck discharges, EPA
emphasizes that deck discharges must also meet any other applicable
discharge requirements under this rule, including but not limited to
the general discharge standards for general operation and maintenance
and oil management detailed in subpart B.
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule prohibits the discharge
of deck wash from all vessels into federally-protected waters except
those vessels that operate exclusively within the boundaries of
federally-protected waters. 40 CFR 139.40(f). This prohibition is
applicable
[[Page 82109]]
only to deck washdown and is not applicable to other deck runoff such
as from precipitation or condensation. The final rule exempts vessels
operating exclusively within federally-protected waters to address new
information provided by commenters and concerns regarding necessary
maintenance of these vessels that requires deck washdown.
7. Desalination and Purification Systems
Distilling and reverse osmosis plants, also known as water
purification plants or desalination systems, generate freshwater from
seawater for a variety of shipboard applications. These include potable
water for drinking, onboard services (e.g., laundry and food
preparation), and high-purity feedwater for boilers. The wastewater
from these systems is essentially concentrated seawater with the same
constituents of seawater, including dissolved and suspended solids and
metals; however, anti-scaling, anti-foaming, and acidic treatments and
cleaning compounds are also injected into the distillation system and
can be present in the discharge. As such, the wastewater can contain
toxic, conventional, and nonconventional pollutants.
EPA was unable to identify new technology or best management
practice options for discharges from desalination and purification
systems, therefore the Agency relied on the BPT/BCT/BAT analysis
underlying the VGP requirements and is requiring substantively the same
requirements included in the VGP. 40 CFR 139.16. EPA did not receive
any comments suggesting revisions to the proposed requirements.
The final rule prohibits discharges resulting from the cleaning of
desalination and purification systems with hazardous or toxic
materials. 40 CFR 139.16(b).
8. Elevator Pits
Most vessels with multiple decks are equipped with elevators to
facilitate the transportation of maintenance equipment, people, and
cargo between decks. A pit at the bottom of the elevator collects
liquids and debris from elevator operations. The liquid and debris that
accumulates in the pits, often referred to as elevator pit effluent,
can be emptied by gravity draining, discharged using the firemain,
transferred to the bilge, or containerized for onshore disposal. The
effluent may contain toxic, conventional, and nonconventional
pollutants such as oil, hydraulic fluid, lubricants, cleaning solvents,
soot, and paint chips.
EPA was unable to identify new technology or best management
practice options for discharges from elevator pits, therefore the
Agency relied on the BPT/BCT/BAT analysis underlying the VGP
requirements and is requiring substantively the same requirements
included in the VGP with slight modifications for clarity. 40 CFR
139.17. EPA did not receive any comments suggesting revisions to the
proposed requirements.
The final rule prohibits the discharge of untreated accumulated
water and sediment from any elevator pit. 40 CFR 139.17(b).
9. Exhaust Gas Emission Control Systems
Exhaust gas emission control systems for reducing sulfur oxides
(SOX) and nitrogen oxides (NOX) in marine exhaust
can produce washwater and residues that must be treated or held for
shoreside disposal. Two such systems are exhaust gas cleaning systems
(EGCSs) and exhaust gas recirculation (EGR) systems.
An EGCS is used primarily to remove SOX from marine
exhaust. Commonly referred to as ``scrubbers,'' these systems capture
contaminants that can end up in washwater and residue that result from
the scrubbing process. EGCS washwater is typically treated and
discharged overboard. Residues are usually disposed of onshore once the
vessel is in port. Untreated EGCS washwater is more acidic than the
surrounding seawater, and it contains toxic, conventional, and
nonconventional pollutants including sulfur compounds, polycyclic
aromatic hydrocarbons (PAHs), and traces of oil, NOX, heavy
metals, and captured particulate matter. Use of an EGCS to scrub
emissions of SOX reduces the pH significantly, primarily
through the formation of sulfuric acid. The high volume of seawater
that some vessels pump for the scrubbing process can result in higher
turbidity in surrounding waters, particularly in shallow areas.
The use of scrubbers on vessels is in large part an outgrowth of
international treaties for reducing sulfur emissions from marine
exhaust. Under MARPOL Annex VI, to which the U.S. is a signatory, the
highest permissible sulfur content of marine fuel used on a vessel when
operating globally is 0.5 percent while the allowable fuel sulfur
content for fuel used on a vessel operating in Emission Control Areas
(ECAs) is restricted to 0.1 percent as of January 2015. In addition,
MARPOL Annex VI includes three tiers of NOX emission
standards, where applicability is based on when the keel of a vessel is
laid; the most stringent Tier III NOX limits apply to any
engine while operated in a NOX ECA. There are two ECAs
relevant to the United States: the North American ECA and the U.S.
Caribbean Sea ECA. Both of these ECAs are for sulfur, particulate
matter, and NOX emissions, and the requirements apply to all
ships while operating in those areas. The 0.1 percent sulfur limit for
marine fuel sulfur content has been in effect since 2015 for ships
operating in the U.S. ECAs. These ECA requirements also apply to
certain internal waters (ECA associated areas) through regulatory
action.
Use of an EGCS is an equivalent method to comply with the MARPOL
Annex VI fuel sulfur requirement as an alternative to costlier low
sulfur fuels while operating in an ECA. Recent information from the
International Council on Clean Transportation (ICCT, 2023) indicates
that the classification society Det Norske Veritas (DNV) projects there
will be over 5,000 scrubbers installed on vessels worldwide by 2025. A
scrubber must meet the same sulfur emission limit as would be achieved
using the relevant compliant fuel (ECA or global).
The EGCSs used on vessels, while a relatively recent development,
are based on technologies that have been deployed for land-based
systems for controlling smokestack emissions for years. This technology
has transferred well to shipboard use for both new and existing
vessels. EGCS technologies used on vessels to meet the MARPOL Annex VI
fuel sulfur standards can be either ``dry'' or ``wet'' depending on
whether they generate wastewater. Dry systems do not generate
wastewater and hence are not subject to these final requirements. The
two main wet EGCS technologies (i.e., those systems that use either
seawater or freshwater to scrub the exhaust) are open-loop and closed-
loop systems. Open-loop systems remove the contaminants from marine
exhaust by running the exhaust through seawater sourced from outside
the vessel and then discharging the resulting washwater back out to
sea. In contrast, closed-loop systems use freshwater and inject caustic
soda to neutralize the exhaust. A small portion of the washwater is
bled off and treated to remove suspended solids that are held for
onshore disposal. While this design is not completely closed-loop, it
can operate in zero discharge mode for a period. Hybrid scrubbers are
systems that can operate either in open- or closed-loop mode. At sea,
these hybrid systems typically operate in open-loop mode, whereas in
nearshore waters, harbors, and estuaries, they operate in closed-loop
mode.
[[Page 82110]]
EGR systems are used to reduce NOX emissions in marine
exhaust. Vessels often use EGR systems to achieve the mandatory Tier
III NOX emissions limits set out in MARPOL Annex VI. These
systems minimize NOX production by cooling part of the
engine exhaust gas and then redirecting it back to the engine air
intake. The addition of the recirculated engine exhaust reduces the
amount of oxygen available for fuel combustion, reducing peak
combustion temperatures and resulting in significantly reduced
NOX formation. The cooling of the recirculated exhaust gas
causes condensation of water vapor formed during combustion, generating
a continuous wastewater stream (bleed-off water) from the condensate.
This condensate can contain toxic, conventional, and nonconventional
pollutants such as particulates (soot, metals, and hydrocarbons) and
sulfur. In some cases, the EGR systems also capture oils, for example
from cylinder lubrication, that are emitted from the combustion process
and collected as part of the scavenged air. Excess bleed-off water that
accumulates in an EGR system is typically discharged overboard
following treatment, and any residues are held for onshore disposal. On
vessels that use high-sulfur fuel and an EGCS, the EGR system bleed-off
water is often combined with the EGCS washwater and processed as a
combined waste stream.
The final standard for EGCS in 40 CFR 139.18 is based largely on
the IMO 2015 Guidelines for Exhaust Gas Cleaning Systems (Resolution
MEPC.259(68))(``2015 IMO EGCS Guidelines''), with additional updates
consistent with the 2021 Guidelines for Exhaust Gas Cleaning Systems,
MEPC.340(77), adopted November 26, 2021 (``2021 IMO EGCS Guidelines'').
The discharge provisions in both the 2015 and 2021 IMO EGCS Guidelines
are largely identical to the 2009 IMO EGCS Guidelines (MEPC.184(59)
that formed the basis of EPA's BAT determination for the 2013 VGP, as
carried forward here. Section 10 of these Guidelines set out discharge
limits for five parameters in scrubber washwater: pH, PAH, turbidity,
nitrates plus nitrites, and additives, as well as handling and disposal
criteria for scrubber residues. This standard applies to all
discharges, upon commissioning and any subsequent/ongoing discharges.
The final standard carries forward most of the EGCS requirements as
proposed with the following three changes.
First, the 2021 IMO EGCS Guidelines added a new section 10.1.7 that
clarified discharge criteria for any EGCS water retained in a temporary
storage tank prior to discharge. For consistency with those
international guidelines and to provide clarity on the applicability of
the discharge criteria when water is retained prior to discharge,
identical criteria (for pH, PAH, and turbidity) are included in the
final rule. Based on the analysis and implementation of the 2021 IMO
EGCS Guidelines, EPA finds this new requirement to represent BAT for
the VIDA regulations.
Second, to align with the IMO EGCS Guidelines, the proposed rule
had omitted the table from the VGP that specifies the nitrates plus
nitrites limits at different flow rates. That table clarified how the
limit varies depending on the discharge flowrates; however, the
standard itself was already fully expressed in proposed rule text.
Based on public comment noting that the table would help operators
better understand the requirements, EPA added this table into the final
rule at 40 CFR 139.18(b)(4)(i), acknowledging that addition of the
table provides clarification but does not alter the requirements as
proposed. Also, the final rule clarifies that the standards for PAH,
turbidity, and nitrates plus nitrites apply downstream of the water
treatment equipment including any reactant dosing unit but upstream of
any seawater addition for pH control prior to discharge. EPA also
incorporated concepts from the 2021 IMO EGCS Guidelines that were
modified to provide more clarity on their application to the discharge
standards, including clarification that megawatt (MW) refers to the
Maximum Continuous Rating (MCR) or 80% of the power rating of all fuel
oil combustion units whose discharge water is being monitored at that
point.
Third, the final rule adds a new 40 CFR 139.18(b)(6) that clarifies
the prohibition of discharges of sludge or residues generated from the
treatment of EGCS or EGR washwater or bleed-off water. EPA added this
requirement to the final rule to clarify the expectation of the
proposed rule that treatment residuals are managed properly. This
prohibition is consistent with both the 2021 IMO EGCS Guidelines and
the VGP.
With respect to pH, several commenters requested additional detail
and clarification on how the pH limit applies under the two different
options in the standard. The first option is based strictly on the
vessel's washwater discharge having a pH of no less than 6.5 at
overboard discharge except during maneuvering and transit, when a
maximum difference of two pH units is allowed between inlet water and
overboard discharge. In that scenario, the following requirements
apply:
When stationary, the pH limit is 6.5; and
During maneuvering and transit, a maximum difference of
two pH units is allowed between inlet water and overboard discharge.
So, during maneuvering and transit, if the pH of ambient (intake) water
is, for example, 8.7, the pH limit is 6.7, or, if the ambient (intake)
water is 8.0, the pH limit is 6.0.
The second option is modeling-based. Under this option, the vessel
performs modeling to determine the pH at the overboard discharge point
while the vessel is stationary that will not cause the ambient water at
four meters from the hull to fall below a pH value of 6.5. For vessels
that choose this option, the modeled value for pH of the overboard
discharge then is the pH discharge limit at all times in all locations
so that, for example, a modeled pH limit of 5.8 becomes the overboard
discharge limit at all times, including while in port and during
maneuvering and transit and for which there is no additional allowance
of two pH units between uptake and discharge.
EPA also received several comments requesting that the Agency ban
discharges from open-loop scrubbers outright (i.e., establish a zero-
discharge standard for open-loop scrubbers) as has been done in some
other locations around the world. EPA received no information
demonstrating that such a ban is technically available as a uniform
national standard. For example, EPA has not received information
demonstrating that there is sufficient low sulfur fuel (which may be
needed to comply with emissions standards if scrubber discharges are
not permitted) or that adequate onshore reception facilities are
available for disposal of scrubber washwaters and residues that would
be generated by the use of other scrubber configurations such as
closed-loop or hybrid systems. Technical committees at the IMO are
currently revisiting the need to perform additional assessments of
environmental impacts from EGCS discharges, and EPA will continue to
monitor the availability of research findings compiled in connection
with these discussions.
Another commenter stated that EPA should have included use of shore
power as an alternative to use of scrubbers; however, the use of shore
power has many considerations and barriers (U.S. EPA, 2022). EPA
recommended, but did not require, its use in the VGP. Currently,
vessels use shore power when available, in part because that allows
them to avoid the
[[Page 82111]]
turbidity issues associated with use of the EGCSs. However, shore power
is often not an option in smaller ports due to load issues. EPA
continues to recommend, but not require, the use of shore power when
available and feasible for vessel use.
The final exhaust gas emission control standard also includes
requirements for discharges of EGR bleed-off water and residues in
recognition of the fact that these discharges can exhibit low pH and
contain other toxic, conventional, and nonconventional pollutants
covered under the CWA. The VGP did not identify EGR discharges largely
because EGR systems are relatively new to vessels, consistent with the
effect of the NOX emissions standards established in MARPOL
Annex VI. The final standard for discharges from EGR systems is based
primarily on the IMO 2018 Guidelines for the Discharge of Exhaust Gas
Recirculation (EGR) Bleed-Off Water (MEPC 307(73))(``2018 IMO EGR
Guidelines''), that is similar to the 2015 IMO EGCS Guidelines, with a
few key differences that recognize the composition of EGR bleed-off
washwater and the onboard process for handling this waste stream. EPA
has utilized the analysis and implementation of the 2018 IMO EGR
Guidelines to aid it in determining that its new EGR standards are
technologically available and economically achievable.
The final rule carries forward most of the EGR requirements as
proposed with some modifications or clarifications, based on public
comment. For clarity, EPA revised the heading of 40 CFR 139.18(c) from
the proposed rule to reflect an ``exclusion'' from the 40 CFR 139.18(b)
requirements rather than a different ``applicability'' of the
requirements.
As described in the proposed rule preamble (85 FR 67818, October
26, 2020, section VIII.B.9.), EPA proposed to apply this standard based
on the location of the vessel, consistent with how the Agency assessed
and applied other requirements in the rule; namely, the proposed
standard considered whether a vessel was in port, underway, or outside
of the waters of the United States or the waters of the contiguous
zone. The proposed rule did not specify that the exclusion from the
discharge standard in 40 CFR 139.18(b) only applies if the vessel is no
longer in port; however, EPA did describe such in the proposed rule
preamble. Thus, to be consistent with both EPA's intended approach and
the 2018 IMO EGR Guidelines, the final rule clarifies that the EGR
bleed-off exclusion from the 40 CFR 139.18(b) requirements only apply
if the EGR bleed-off is not retained in a holding tank prior to
discharge, and the vessel is no longer in port, is underway, and is
operating on a fuel that meets the sulfur content limits specified in
Regulation 14 of MARPOL Annex VI (that is, 0.10 percent mass by mass
(m/m) sulfur content limit while operating in the North American or
U.S. Caribbean Sea ECAs, as of January 1, 2015; 0.50 percent m/m fuel
sulfur content limit while operating in other U.S. coastal areas as of
January 1, 2020).
Comments on the proposed EGR requirements highlighted that the
exclusion and prohibition in the proposed rule may not have been clear
with respect to applicability of requirements based on type of fuel
used and whether EGR discharges are retained in a holding tank prior to
discharge. As such, the language in the final rule is restructured with
a goal of clarifying those instances when EGR discharges are or are not
subject to the 40 CFR 139.18(b) discharge standard and consistent with
the 2018 IMO EGR Guidelines. Notably, for a vessel not operating on
fuel that meets the sulfur content limits specified in Regulation 14 of
MARPOL Annex VI, the final rule prohibits the discharge of EGR bleed-
off retained in a holding tank prior to discharge unless the vessel is
underway, not in port, and in compliance with the 40 CFR 139.18(b)
discharge standard.
10. Fire Protection Equipment
Fire protection equipment includes all components used for fire
protection including, but not limited to, firemain systems, sprinkler
systems, extinguishers, and firefighting agents, such as foam. Firemain
systems draw in water through the sea chest to supply water for fire
hose stations, sprinkler systems, and firefighting foam distribution
stations. Firemain systems can be pressurized or non-pressurized and
are necessary to ensure the safety of the vessel and crew. The systems
are also tested regularly to ensure that the system will be operational
in an emergency. Additionally, firemain systems have numerous secondary
purposes onboard vessels, such as for deck and equipment washdowns and
anchor/anchor chain rinsing. However, whenever the firemain system is
used for a secondary purpose, such as deck washdown, any resulting
incidental discharge is required to meet the Federal standard of
performance for that secondary use. Firemain water can contain a
variety of constituents, including copper, zinc, nickel, aluminum, tin,
silver, iron, titanium, and chromium. Many of these constituents can be
traced to the corrosion and erosion of the firemain piping system,
valves, or pumps.
Firefighting foams (fluorinated and non-fluorinated) can be added
to a firemain system and mixed with seawater to address emergencies
onboard a vessel. The constituents of firefighting foam can vary by
manufacturer but can include persistent, bioaccumulative, toxic, and
non-biodegradable ingredients. Discharges of firefighting foam can also
contain phthalate, copper, nickel, and iron, which can be constituents
in the composition of firemain piping. Fluorinated firefighting foam
contains per- and poly-fluoroalkyl substances (PFAS) or their
precursors; examples include aqueous film forming foam, alcohol
resistant aqueous film forming foam, film-forming fluoroprotein foam,
fluoroprotein foam, alcohol-resistant fluoroprotein foam, and other
fluorinated compounds. Non-fluorinated firefighting foam does not
contain PFAS or their precursors; examples include protein foam,
alcohol-resistant protein foam, synthetic fluorine free foam, and
synthetic alcohol-resistant fluorine free foam. PFAS such as
perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA),
among others, are persistent and bioaccumulative. Many PFAS are toxic
and/or carcinogenic. Information regarding the presence of fluorinated
surfactants and toxic or hazardous substances in firefighting foam are
typically found on the safety data sheets for individual products.
Additionally, other types of foams exist that can be used in fire
equipment systems that are not intended for fire suppression but are
designed for testing and training. These foams are often called testing
or training foams, tend to be less expensive, and can mimic the
properties of firefighting foams.
The final rule applies to discharges from fire protection equipment
during testing, training, maintenance, inspection, or certification. 40
CFR 139.19(c). Based on comments received on the proposed rule, the
final rule includes a definition for ``fire protection equipment'' and
clarifies in 40 CFR 139.19(a) the applicability of the standards to
discharges from the firemain for secondary uses such as deck washdown
and anchor and anchor chain rinsing. Per 40 CFR 139.19(a), the final
standard does not apply to the use of fire protection equipment in
emergency situations or when compliance would compromise the safety of
the vessel or life at sea. See 40 CFR 139.1(b)(3).
The final rule prohibits the discharge of fluorinated firefighting
foam except
[[Page 82112]]
in instances when required by the USCG (i.e., the Secretary) for
certification and inspection or by the marine inspector to ensure
vessel safety and seaworthiness. 40 CFR 139.19(b). The final rule
clarifies that this includes activities performed pursuant to 46 CFR
31.10 through 31.18(c) and 46 CFR 107.235(b)(4), or otherwise required
by the marine inspector to ensure vessel safety and seaworthiness
(e.g., pursuant to 46 CFR 31.10 through 31.17(a)(4), 46 CFR 71.25
through 71.50, 46 CFR 91.25 through 91.50, or similar). Id. The USCG
has indicated that, in limited circumstances, USCG-required inspections
and certification testing of vessels with fluorinated foam systems may
result in discharges of fluorinated foam while in port to ensure vessel
safety. In many instances, vessels with fluorinated foams can test,
train, or maintain the system without discharging the foam, such as
testing without foam, collecting the foam such that it is not
discharged, or using an alternative non-fluorinated foam (FFFC, 2020;
NFPA, 2016). According to the National Fire Protection Association
(NFPA), there are many firefighting foams and training foams that are
non-fluorinated that can be used for testing, training, and maintenance
(FFFC, 2020; NFPA, 2016). Several commenters expressed support for the
prohibition of discharges of fluorinated foam except as directed by the
USCG. Commenters confirmed that in many instances testing, training,
and maintenance can be performed with water unless USCG regulations
require foam.
EPA also considered other more stringent requirements than the VGP
in relation to the discharge of firefighting foam. Specifically, EPA
explored requirements that would include product substitution to use
firefighting foams that do not contain bioaccumulative or toxic or
hazardous materials. EPA has used product substitution for other
technology-based rules, such as those that apply to oil and gas. See 40
CFR part 435. As such, EPA considered, for the purposes of testing,
training, maintenance, inspection, or certification, also prohibiting
the discharge of non-fluorinated firefighting foams that contain
bioaccumulative or toxic or hazardous materials (as identified in 40
CFR 401.15 or defined in 49 CFR 171.8). Based on the Best Practice
Guidance for Use of Class B Firefighting Foams from the Fire Fighting
Foam Coalition (FFFC, 2020), NFPA codes and standards--NFPA 11--
Standards for Low-, Medium-, and High-Expansion Foam (NFPA, 2016), and
discussions with the USCG, testing and training methods exist that
limit or eliminate the need to discharge foam (FFFC, 2020; NFPA, 2016).
Specifically, in many situations it may be possible to perform these
activities by only using water (water equivalency method), collecting
the foam, or using non-fluorinated training foam that does not contain
bioaccumulative or toxic or hazardous materials. EPA reviewed numerous
foam Safety Data Sheets for bioaccumulative or toxic or hazardous
materials and identified several potential foam substitute options
(U.S. EPA, 2020).
EPA solicited feedback on: (1) the availability of non-fluorinated
foams, training foams, or surrogate test liquids that do not contain
bioaccumulative or toxic or hazardous materials that can satisfy
firefighting testing, training, and maintenance needs; (2) the extent
to which vessels are already using these alternative foams; (3) the
extent to which vessels are already performing testing, training, and
maintenance using only water; (4) the number of vessels and types of
systems that are not able to use the water-equivalency method; (5) the
extent to which the vessel community is collecting foam prior to
discharge; and (6) economic considerations associated with prohibiting
the discharge of these types of non-fluorinated firefighting foams, and
any other information that would support the Agency's determination of
whether to expand the prohibition of the discharge of firefighting
foams to include non-fluorinated foams that contain bioaccumulative or
toxic or hazardous materials. Several commenters provided additional
information on the solicited topics above, including materials
demonstrating the limited availability of alternative foams and
practical challenges associated with their use, such as the need for
additional piping and onboard storage of multiple foam types. The input
from commenters described above is consistent with the often limited
information on bioaccumulation, toxicity, and hazardous substances
found in Safety Data Sheets of foam formulations, as sections on
environmental impact of chemicals are not mandatory (Appendix D to 29
CFR 1910.1200), and there is often omission or non-disclosure of
information on presence and effects of persistent compounds (DEHP,
2016). EPA finds that it is not reasonable to require zero discharge of
non-fluorinated foams that contain bioaccumulative or toxic or
hazardous materials because the record does not demonstrate sufficient
information and availability of alternative foams that meet
requirements for testing, training, maintenance, inspection, or
certification in all instances, as well as practical challenges with
their use. EPA deems it appropriate to consider whether alternatives
are readily available which meet requirements (i.e. consistently
available on the market) (see CWA 304(b)(2)(B) authorizing EPA to
consider ``such other factors as the Administrator deems
appropriate''). Since the information does not support a finding that
these products are readily available, EPA is not requiring zero
discharge of non-fluorinated foams that contain bioaccumulative or
toxic or hazardous materials. EPA may revisit this issue to determine
whether a prohibition of certain types of discharge has become a
practical option in the future.
EPA initially proposed to prohibit any discharge from fire
protection equipment during testing, training, maintenance, inspection,
or certification in port excluding USCG-required inspection or
certification. However, several commenters expressed regulatory and
safety concerns with this approach. These include inconsistencies with
existing regulatory requirements for fire drills, such as in 46 CFR
199.180, as well as the inability to defer drills to outside of port in
all instances. Several commenters also requested language analogous to
the VGP that allows discharges in port if intake is from surrounding
waters or potable water supplies and does not contain any additives or
fluorinated firefighting foam. To address these concerns, the final
rule allows for discharges in port from USCG-required inspection or
certification activities to ensure vessel safety, as well as discharges
from testing, training, maintenance, inspection, or certification
activities if the intake is drawn from surrounding water or a potable
water supply and does not contain additives. 40 CFR 139.19(c).
Several commenters also expressed concern over the lack of
reference to secondary uses in the regulatory text. Some commenters
interpreted the proposed regulations to prohibit secondary uses such as
for deck washdown, anchor chain rinsing, and machinery cooling water.
Commenters articulated that, as proposed, the standard would contradict
the requirements in 40 CFR 139.14 requiring anchor and anchor chain
washdown, as well as prevent vessel and deck washdown and necessary
machinery cooling. Several commenters requested the addition of
language similar to that in the VGP to allow discharges for secondary
purposes
[[Page 82113]]
provided that the intake comes directly from the surrounding waters or
potable water supplies, there are no additions to the water, and that
the discharges meet the applicable standards for that secondary use. To
clarify requirements for secondary uses, the final standard authorizes
discharges from fire protection equipment in port for secondary uses
(such as deck washdown or anchor and anchor chain rinsing) provided the
intake is from surrounding water or a potable water source, does not
contain additives, and the discharge meets requirements for the
specific secondary use. 40 CFR 139.19(d).
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule requires additional
controls for discharges from fire protection equipment for testing,
training, and maintenance purposes for vessels operating in federally-
protected waters. 40 CFR 139.40(g).
11. Gas Turbines
Gas turbines are used on some vessels for propulsion and
electricity generation. Occasionally, they must be cleaned to remove
byproducts that can accumulate and affect their operation. The
byproducts and cleaning products can include toxic and conventional
pollutants including salts, lubricants, combustion residuals,
naphthalene, and other hydrocarbons. Additionally, due to the nature of
the materials being cleaned, there is a higher probability of heavy
metal concentrations. Rates and concentrations of gas turbine wash
water discharge vary according to the frequency of washdown, and under
most circumstances vessel operators can choose where and when to wash
down gas turbines.
EPA was unable to identify new technology or best management
practice options for discharges from gas turbines, therefore the Agency
relied on the BPT/BCT/BAT analysis underlying the VGP requirements and
is requiring substantively the same requirements included in the VGP.
40 CFR 139.20. EPA did not receive any comments suggesting revisions to
the proposed requirements.
The final rule prohibits the discharge of untreated gas turbine
washwater unless determined to be infeasible. 40 CFR 139.20(b).
12. Graywater Systems
Graywater is water drained or collected from sources such as
galleys, showers, baths, sinks, and laundry facilities. Graywater
includes drainage from dishwater; however, the discharge of food waste
and food waste derivates are regulated as garbage and are not
incidental to the normal operation of a vessel. Therefore, they are not
considered graywater for purposes of this rule. Graywater discharges
can contain bacteria, pathogens, oil and grease, detergent and soap
residue, metals (e.g., cadmium, chromium, lead, copper, zinc, silver,
nickel, mercury), solids, and nutrients. Some vessels have the capacity
to collect and hold graywater for later treatment and discharge.
Vessels that do not have graywater holding capacity continuously
discharge it to receiving waters. It is estimated that 30 to 85 gallons
of graywater is generated per person per day. Graywater generation
rates per person can vary based on the types of activities onboard the
vessel. For example, vessels with overnight accommodations and onboard
leisure activities are expected to generate higher volumes of graywater
than a working vessel because passengers and crew are using more water
for bathing, food preparation, and other such activities (U.S. EPA,
2011d). Estimates of graywater generation by cruise ships that can
accommodate approximately 3,000 passengers and crew range from 96,000
to 272,000 gallons of graywater per day or 1,000,000 gallons per week.
Strategies to minimize the discharge of graywater can include reducing
the production of graywater, holding the graywater onboard, or using a
reception facility.
The final rule defines ``graywater'' to mean drainage from galley,
shower, laundry, bath, water fountain, and sink drains, and other
similar sources. 40 CFR 139.2. The revised definition is intended to
provide better clarity regarding the sources of graywater; however, it
does not change the types of wastewaters that were covered by the VGP
and now regulated under this final rule. The definition now explicitly
references the galley drains as a graywater source, and favors the term
``sinks'' over ``washbasins'' as a more appropriately expansive term.
The definition for ``graywater'' in the proposed rule included a
sentence describing drainage from sources that do not constitute
graywater, but the list was removed as it was not exhaustive. EPA
notes, however, that drainage from toilets, urinals, hospitals or other
medical spaces or equipment, animal spaces, and cargo spaces are not
considered graywater for purposes of this rule.
The final rule maintains many of the requirements included in the
proposed rule, including the requirements for vessel operators to
minimize the discharge of graywater and to discharge while underway
when practical and as far from shore as practical. The final rule also
requires that soaps, cleaners, and detergents used by vessel owner/
operators that enter the graywater system be minimally-toxic,
phosphate-free, and biodegradable. The final rule clarifies the
requirement to include products provided to persons onboard (e.g.,
passengers) by vessel owner/operators. EPA acknowledges the difficulty
in applying such a requirement to products brought onboard by
passengers/guests and therefore does not include such a requirement.
The final rule also clarifies the requirement to include ``other
substances'' to ensure that similar products entering the graywater
systems are similarly minimally-toxic, phosphate-free, and
biodegradable. The final rule includes the requirement to minimize the
introduction of kitchen oils and food and oil residue to the graywater
system. While filtered dishwater and drainage from galley sinks and
floor drains are regulated as graywater under this rule, food waste and
its derivatives are not. EPA acknowledges that food waste may
unavoidably enter the graywater system during normal dishwashing, so
this requirement is intended to ensure that the amount entering the
system is minimized.
The final rule identifies a numeric discharge standard that must be
met for discharges of graywater from any new vessel of 400 GT and above
that is certificated to carry 15 or more persons and provides overnight
accommodations to those persons; any passenger vessel (excluding any
ferry) with overnight accommodations for 500 or more persons; any
passenger vessel (excluding any ferry) with overnight accommodations
for 100-499 persons unless the vessel was constructed before December
19, 2008, and does not voyage beyond 1 NM from shore; and any new ferry
authorized by the USCG to carry 250 or more persons. Such vessels could
be equipped either with a treatment system to meet the standards in 40
CFR 139.21(f) or sufficient storage capacity to retain all graywater
onboard while operating in waters subject to the VIDA. Under the
proposed rule, the discharge of graywater from any new vessel of 400 GT
and above was required to meet the numeric discharge standard. This
proposal was based on VGP reporting data that indicated between one-
third and one-half of manned vessels of 400 GT or above that are not
cruise ships or ferries are equipped with a treatment system for
graywater, graywater mixed
[[Page 82114]]
with sewage, or a combined treatment system that may treat graywater.
Based on EPA's knowledge of sewage handling practices, a wastewater
that is frequently commingled with graywater, and comments received
regarding the need for adequate pumpout facilities, EPA further assumed
that vessels built with storage capacity would be serviced by
stationary and mobile (e.g., trucks and barges) pumpout facilities that
currently receive sewage and graywater from vessels, with increasing
demand for these services driving increased availability. In light of
public comments received on the proposed rule, however, EPA presented
an additional regulatory option in the 2023 supplemental notice to
limit the applicability of the provision to those new vessels of 400 GT
and above that are certificated to carry 15 or more persons and provide
overnight accommodations to those persons. This additional regulatory
option was adopted in this rule on the basis of the information
presented by EPA in the supplemental notice and the feedback received
during the comment period. The final rule also now defines ``new
ferry'' to clarify the applicability of 40 CFR 139.21(e)(4).
Additionally, the final rule clarifies that ``passenger vessel'' in 40
CFR 139.21(e)(2) and (3) does not include ferries for purposes of those
provisions. This is consistent with the VGP that previously used the
terminology ``cruise ship'' for those requirements. Furthermore, the
graywater systems standard already includes specific requirements for
ferries.
The final numeric discharge standard generally mirrors that from
the proposed rule, but deviates from the VGP in that it does not
include the percent removal requirements for BOD and TSS. EPA
acknowledges that, in the absence of the percent removal requirements
for BOD and TSS, this provision may be less stringent than the VGP;
however, consistent with CWA section 312(p)(4)(D)(ii)(II), the
Administrator may revise a standard of performance to be less stringent
than an applicable existing requirement if the Administrator determines
that a material technical mistake occurred or if information becomes
available that was not reasonably available when the Administrator
promulgated the initial standard of performance. EPA made a material
technical mistake in the VGP by including the percent removal
requirement, because it is based on secondary treatment regulations for
land-based municipal sewage, wherein the characteristics of the
influent are well-understood but the facility has little control over
the inputs. Onboard vessels, there is significant variability in
graywater characteristics but greater ability to control the
contribution of BOD and TSS, for example, by separating galley
graywater from other sources of graywater entering the treatment
system. EPA also became aware of new information through implementation
of the VGP that the requirement for the 30-day average percent removal
for BOD and TSS to not be less than 85 percent is also difficult to
monitor and enforce on a vessel, unlike at a land-based facility where
influents and effluents are more easily monitored, which was
information not available to the Administrator when the percent removal
requirement was promulgated. Additionally, the retained requirements
are substantively the same as those under the VGP in terms of pollutant
reductions achieved. The numeric limits are consistent with the VGP,
while the percent removal requirements did not make sense in the
context of onboard application. VGP reporting data for graywater
systems demonstrates that the majority of vessels did not, or were not
able to, characterize influent for BOD and TSS. Without influent
information, it is not possible to calculate percent reduction.
Therefore, the technical mistake discussed above, coupled with this new
information, contributed to EPA's determination that it was appropriate
to eliminate the percent removal requirements.
As requested by commenters, the final numeric discharge standard
includes additional clarifying language. First, the standard for fecal
coliform at 40 CFR 139.21(f)(1)(i) and (ii) reflects units of both MPN/
mL and cfu/mL on the basis that newer microbiological test methods have
MPN outputs and, while the test methods differ, the number of bacteria
in the tested sample are comparable to the numeric discharge standard.
The standard for fecal coliform at 40 CFR 139.21(f)(1)(ii) now also
clarifies that percentage of samples required to comply with the
specified fecal coliform limit is tied to the same 30-day period as the
geometric mean standard in 40 CFR 139.21(f)(1)(i). Finally, the
standard at 40 CFR 139.21(f)(5) and (f)(5)(i) uses ``total residual
oxidizers,'' instead of ``total residual chlorine'' for consistency
with the wording in other similar standards (e.g., ballast tanks). The
provision now reads, ``For any discharge from a graywater system using
chlorine, total residual oxidizers must not exceed 10.0 [micro]g/L.''
The numeric discharge standards are based on the performance of
``advanced wastewater treatment systems (AWTSs),'' which are
sophisticated marine sanitation devices. In evaluating options for
graywater treatment, EPA reaffirmed that treatment of commingled
graywater and sewage by an AWTS produces significant constituent
reductions in the resulting effluent. AWTSs differ from traditional
treatment systems in that they generally employ enhanced methods for
treatment, solids separation, and disinfection, such as through the use
of membrane technologies and UV disinfection. The numeric discharge
standard for graywater systems uses the pathogen indicator fecal
coliform, though AWTSs also greatly reduce the concentrations of other
pathogen indicators, such as E. coli and enterococci, during treatment
and disinfection (U.S. EPA, 2008). AWTSs are currently in wide use and
economically achievable for certain vessel classes. For example, the
Cruise Lines International Association (2019) reports that 68 percent
of member lines' global fleet capacity is currently served by AWTSs.
Also, all new ships on order by member lines will be equipped with
AWTSs. In Alaska, under the existing ``Large Cruise Ship General
Permit,'' certain large commercial passenger vessels may only discharge
wastewater (including sewage and graywater) that has been treated by an
AWTS or equivalent system. As an alternative to using a treatment
system to meet the numeric discharge standard, these vessels may
instead be equipped with sufficient storage capacity to retain
graywater onboard while operating in waters subject to the VIDA.
For graywater, the numeric discharge standards rely on a mix of
averaging periods and instantaneous maximums, both of which are
commonly used in setting numeric effluent discharge limits depending on
the nature of the pollutant and the characteristics of the discharger.
Where EPA adopted a long-term average as opposed to an instantaneous or
daily maximum, it did so based on two reasons. First, EPA considered
the regulatory setting. Monitoring discharges onboard a vessel can
present unique challenges compared to monitoring discharges from land-
based facilities, which is the typical regulatory context for numeric
effluent discharge limits. Systems that are designed to meet an
instantaneous maximum require a higher level of control, and therefore
less variability, in the system. Where it was practical to adopt a
standard based on an instantaneous or daily maximum, EPA attempted to
do so. For example, the final standard for discharges from ballast
tanks includes the use of instantaneous maximums. As indicated in the
ballast tanks section,
[[Page 82115]]
the challenges associated with collecting and testing representative
samples of ballast water at the time of discharge required a different
approach. Second, EPA considered how the pollutant operates in the
environment. The use of an instantaneous maximum is preferred over the
use of a long-term average where the upper bounds of variability in the
discharge may cause serious environmental harm. As compared to, for
example, the discharge of ANS from untreated ballast water which can
potentially spread and reproduce, the pollution associated with
untreated graywater discharges contributes to a more gradual decline in
environmental quality. As such, the use of long-term averages in 40 CFR
139.21(f) allows for the variability that is expected in a well-
operated treatment system.
At the same time, the monthly averages require the vessel operator
to remain vigilant to ensure that, despite this variability, discharges
consistently meet the numeric limit. Vessels to which the standard
applies are expected to operate treatment systems that can consistently
achieve compliance with the monthly average based on the vessel's
expected loadings (or otherwise be equipped with storage to prevent
discharges). Pursuant to the general operation and maintenance
standards described in subpart B, vessels are expected to discharge
while underway when practical and as far from shore as practical. This
encourages commingling of the graywater constituents and further
decreases the risks associated with variability in the system. EPA
recognizes that the option to install AWTSs or sufficient holding
capacity may be unavailable for certain vessels for such reasons as
cost, stability of the vessel, or space constraints. As such, EPA does
not propose that all vessels be required to treat graywater discharges
to the numeric discharge standard found in 40 CFR 139.21(f).
The final rule prohibits the discharge of graywater in certain
locations unless the discharge meets the numeric discharge standard in
40 CFR 139.21(f). The prohibition applies to discharges within 3 NM
from shore for any vessel that voyages at least 3 NM from shore and has
remaining available graywater storage capacity. Similarly, the
prohibition applies to the discharge of graywater within 1 NM from
shore from any vessel that voyages at least 1 NM but not more than 3 NM
from shore and has remaining available graywater storage capacity. In
other words, for vessels that voyage at least 3 NM from shore and have
available storage capacity, the discharge of untreated graywater must
occur while further than 3 NM from shore. For vessels that voyage at
least 1 NM but not beyond 3 NM from shore and have available storage
capacity, the discharge of untreated graywater must occur while further
than 1 NM from shore. These limitations apply unless the graywater is
treated in accordance with 40 CFR 139.21(f), and the language in 40 CFR
139.21(f) was updated to make clear that the vessels identified in 40
CFR 139.21(d) must also meet the numeric discharge standard if
discharging graywater, not just those identified in 40 CFR 139.21(e).
If a vessel is configured to be able to divert graywater to tanks
typically used for other purposes, and it is safe and permissible to do
so, then such tanks are considered by EPA to be available capacity for
purposes of the foregoing requirements. These requirements are intended
to limit nearshore discharges of pollutants without a significant
increase in compliance costs because the requirements apply only to
those vessels with available storage capacity.
The final rule does not include graywater discharge standards for
commercial vessels in the Great Lakes, consistent with CWA section
312(a)(6) that specifies the term ``sewage,'' with respect to
commercial vessels on the Great Lakes, shall include graywater. As
such, graywater discharges from commercial vessels on the Great Lakes
are subject to the requirements in CWA sections 312(a)-(l) and the
implementing regulations at 40 CFR part 140 and 33 CFR part 159.
Additionally, per CWA section 312(p)(9)(A)(v), the general preemption
of State authority to adopt or enforce any law, regulation, or other
requirement with respect to the covered incidental discharges does not
apply to the discharge of graywater from a passenger vessel in Alaska
(including all waters in the Alexander Archipelago) carrying 50 or more
passengers.
Non-commercial vessels operating on the Great Lakes may only
discharge graywater if the discharge is treated such that it does not
exceed 200 fecal coliform forming units per 100 milliliters and
contains no more than 150 milligrams per liter of suspended solids.
This is because the Agency determined that graywater treatment using an
existing system meeting the 40 CFR part 140 standards represents the
appropriate level of control for those non-commercial vessels operating
in the Great Lakes that do not hold their graywater for onshore
disposal. Hence, either treatment devices or adequate holding capacity
are available and used for managing graywater from vessels operating on
the Great Lakes. The final rule clarifies that this provision only
applies if the vessel is not subject to the requirements under 40 CFR
139.21(e), where EPA has determined a differing level of control is
appropriate, to avoid ambiguity when a vessel is potentially subject to
both 40 CFR 139.21(e) and (g).
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule establishes additional
controls for discharges from graywater systems into federally-protected
waters. 40 CFR 139.40(h).
13. Hulls and Associated Niche Areas
a. Anti-Fouling Coatings
Vessel hulls are often coated with anti-fouling compounds to
prevent or inhibit the attachment and growth of biofouling organisms.
Selection, application, and maintenance of an appropriate anti-fouling
coating type and thickness according to vessel profile is critical to
effective biofouling management, and therefore preventing the
introduction and spread of ANS from the vessel hull and associated
niche areas. Multiple types of anti-fouling coatings are available for
use, including hard, controlled depletion or ablative, self-polishing
copolymer, and fouling release coatings. The use of non-biocidal and
non-ablative anti-fouling coatings, when practicable, is recommended.
Anti-fouling coatings may employ physical, biological, chemical, or a
combination of controls to reduce biofouling. Those that contain
biocides prevent the attachment of biofouling organisms to the vessel
surface by continuously leaching substances that are toxic to aquatic
life. The most commonly used anti-fouling biocide is copper.
Manufacturers may also combine copper with other biocides, often called
booster biocides, to increase the effectiveness of the anti-fouling
coating. Cleaning the anti-fouling coating typically results in pulses
of biocide into the environment, particularly if surfaces are cleaned
within the first 90 days following application.
The final rule requires that the selection of an anti-fouling
coating for the hull and associated niche areas must be specific to the
vessel's operational profile, and that any biocidal anti-fouling
coatings used must have appropriate biocide release rates and
components that are biodegradable once separated from the vessel
surface. 40 CFR 139.22(c)(1). Operational profile factors can influence
biofouling rates and include the vessel speed during a typical voyage,
aquatic environments
[[Page 82116]]
traversed, type of surface painted, typical water flow for any hull and
niche areas, planned periods between drydock, and expected periods of
inactivity or idleness. Generally, an optimal biocide will have broad
spectrum activity, low mammalian toxicity, low water solubility, no
bioaccumulation up the food chain, no persistence in the environment,
and compatibility with raw materials (IMO, 2002). Non-biocidal anti-
fouling coatings are available and vessels that typically operate at
high speeds may effectively manage biofouling, particularly
macrofouling, with non-biocidal anti-fouling coatings. Additionally,
vessels operating in waters with lower biofouling pressure and those
that spend less time at dock are expected to have a lower biofouling
rate and should select either non-biocidal anti-fouling coatings or
anti-fouling coatings with low biocide discharge rates. However, these
non- or low-biocidal anti-fouling coatings may not be suitable for all
operational profiles (e.g., for vessels that occasionally endure
extended idling).
Adherence to manufacturer specifications is necessary to ensure the
longevity and effectiveness of the anti-fouling coating and is
considered best practice. If an anti-fouling coating is not properly
selected, applied, or maintained, it will likely show signs of
deterioration, such as indications of excessive cleaning actions (e.g.,
brush marks) or blistering due to the internal failure of the paint
system. Such deterioration may allow for biofouling organisms to grow
on exposed surfaces, increasing the potential for the introduction and
spread of ANS. Improper application and maintenance of an anti-fouling
coating may also increase the discharge of particles into the aquatic
environment and degradation of the integrity of wetted surfaces. The
VGP required that any anti-fouling coatings be applied, maintained, and
removed consistent with the FIFRA label, if applicable. The final rule
similarly requires that anti-fouling coatings be applied, maintained,
and reapplied consistent with manufacturer specifications, including
but not limited to the thickness, the method of application, and the
lifespan of the coating. 40 CFR 139.22(c)(2). One option for meeting
this requirement is to schedule the in-service period of the anti-
fouling coating to match the vessel's drydock cycles. Larger vessels,
particularly those used in the carriage of goods, are subject to
requirements for safety inspections and maintenance activities that
dictate how frequently they must be drydocked. Factoring this schedule
into coating selection ensures the anti-fouling coating will
sufficiently protect the vessel for the period needed without creating
additional leachate or wastes.
b. Tributyltin (TBT) Requirements
The International Convention on the Control of Harmful Anti-fouling
Systems on Ships (AFS Convention) was adopted in 2001 and came into
force in 2008. The United States became a contracting party to the AFS
Convention on November 21, 2012. Domestically, the Clean Hull Act of
2009 implements the requirements of the AFS Convention. Consistent with
the AFS Convention, the Clean Hull Act, and the VGP, the final rule
requires that anti-fouling coatings not contain TBT or any other
organotin compound used as a biocide. Additionally, 40 CFR
139.22(c)(3)(i) requires that any vessel hull previously covered with
an anti-fouling coating containing TBT (whether used as a biocide or
not) or any other organotin compound (if used as a biocide) must either
(1) maintain an effective overcoat that forms a barrier on the vessel
hull so that no TBT or other organotin leaches from the vessel hull; or
(2) remove any TBT or other organotin compound from the vessel hull.
EPA is unaware of any non-biocidal use of TBT that would result in a
residual presence in anti-fouling paints. Combined, the requirements in
the final rule are substantively equivalent to a zero-discharge
standard of TBT from vessel hulls. EPA expects that few, if any,
vessels have exposed TBT coatings on their hulls and that the final
standard for all organotin compounds, including TBT, is technologically
available based on other anti-fouling coating options.
Other less toxic organotin compounds such as dibutyltin oxide are
used in small quantities as catalysts in some non-biocidal anti-fouling
coatings. One class of non-biocidal anti-fouling coatings, sometimes
referred to as fouling release coatings, produce a non-stick surface to
which fouling organisms cannot firmly adhere. To function properly, the
coating surface must remain smooth, intact, and not leach into the
surrounding water. Because these less toxic organotins are used as a
catalyst in the production of non-biocidal anti-fouling coatings, such
production may result in trace amounts of organotin in anti-fouling
coatings. Consistent with the AFS Convention, the Clean Hull Act, and
the VGP, the final rule authorizes the use of non-biocidal anti-fouling
coatings that contain trace amounts of catalytic organotin (other than
TBT) if the trace amounts of organotin are not used as a biocide. The
final rule requires that, when used as a catalyst, an organotin
compound must contain less than 2,500 milligrams total tin per kilogram
of dry paint and must not be designed to slough or otherwise peel from
the vessel hull. 40 CFR 139.22(c)(4). Incidental amounts of an anti-
fouling coating discharged by abrasion during cleaning or after contact
with other hard surfaces (e.g., moorings) are acceptable.
c. Cybutryne Requirements
Cybutryne, commonly known as Irgarol 1051, is a biocide that
functions by inhibiting the electron transport mechanism in algae, thus
inhibiting growth. There are numerous commercially available
antifoulants that are similar in cost and are less harmful to the
aquatic environment (IMO, 2018). Restrictions on cybutryne are already
in place in a number of countries globally, and cybutryne is therefore
less widely used compared to other antifoulants (IMO, 2017). Anti-
fouling coatings that do not contain cybutryne are both technologically
available and economically achievable. Consistent with a recent 2020
MEPC amendment to the AFS Convention, the final rule prohibits the
application of cybutryne-containing anti-fouling coatings on hulls and
niche areas. 40 CFR 139.22(c)(5). In cases where anti-fouling coatings
contain cybutryne in the external anti-fouling coating layer of the
hull or external parts of surfaces, the final rule requires either (1)
the removal of any cybutryne coating; or (2) the application and
maintenance of an effective overcoat that forms a barrier so that no
cybutryne leaches from the underlying anti-fouling coating. The latter
is provided as an option to comply with this requirement because
overcoats are commercially available. Incidental amounts of anti-
fouling coating discharged by abrasion during cleaning or after contact
with other hard surfaces (e.g., moorings) are acceptable.
d. Copper Requirements
Copper, primarily in the form of cuprous oxide, is the most common
biocidal anti-fouling coating, accounting for approximately 90 percent
of the volume of sales of specialty anti-fouling coatings in the United
States (U.S. EPA, 2018). Copper is a broad-spectrum biocide that
effectively prevents both microfouling and macrofouling. Copper is
considered less harmful to the aquatic environment than TBT-containing
compounds, but its use has nevertheless contributed to loadings in
copper-impaired waters. The final rule requires
[[Page 82117]]
that, as appropriate based on vessel class and operations, alternatives
to copper-based anti-fouling coatings (e.g., non-biocidal anti-fouling
coatings) or coatings with lower biocidal release rates be considered
for vessels spending 30 or more days per year in copper-impaired waters
or using these waters as their home port. 40 CFR 139.22(c)(6). EPA
determined that there are no direct substitutions for copper as a
biocide that are as affordable or as effective without posing similar
risks to non-target aquatic species (U.S. EPA, 2018). As such, the
final rule does not require the selection of an alternative anti-
fouling coating for vessels.
The significance of discharges from a biocidal anti-fouling coating
depends not only on the substance used, but also on the leaching rate
of the biocide (IMO, 2009). The leaching rate is the rate of discharge
or entry into the environment from the coating itself. While the
leaching rate of copper from anti-fouling coatings is relatively low
(average discharge rates range from 3.8-22 [mu]g/cm\2\/day), copper-
containing anti-fouling coatings can still account for significant
accumulations of metals in receiving waters of ports where numerous
vessels are present (Valkirs et al., 2003; Zirino and Seligman, 2002).
While maximum leaching rates for copper-based anti-fouling coatings on
recreational vessels have been established both federally and locally,
EPA does not currently have the data available to establish a leaching
rate that would be appropriate for the wide variety of largely
commercial vessels subject to this rule. Therefore, the final rule does
not require a specific, maximum copper leaching rate for anti-fouling
coatings, acknowledging that use of anti-fouling coatings is also
regulated in the United States through the FIFRA.
e. Cleaning
Most commercial seagoing vessels are required to undertake periodic
hull and niche area surveys as part of International Association of
Classification Societies rules and in accordance with IMO conventions
to ensure that hulls and niche areas are maintained in a satisfactory
condition. The VGP, in part 4.1, required all vessels subject to that
permit to inspect the hull annually, or during drydock for those areas
that are not otherwise safe to inspect. Cleaning of hulls and niche
areas, including the removal of any biofouling, is an important
component of hull and niche area maintenance. Niche areas account for
approximately 10 percent of the total wetted surface area of a vessel
(Moser et al., 2017). However, over 80 percent of species sampled in
vessel biofouling studies were found in niche areas (Bell et al.,
2011). Therefore, while representing a smaller surface area compared to
the hull, niche areas may disproportionately contribute to the
discharge of biofouling organisms.
Vessels generally use two types of cleaning techniques to remove
biofouling: cleaning while in drydock and in-water cleaning. Techniques
for in-water cleaning of vessel surfaces can be broadly separated into
two categories: (1) in-water cleaning with capture (IWCC); and (2) in-
water cleaning without capture. IWCC is the use and operation of a
cleaning system for vessel surfaces that is designed to capture and
transport coatings and biofouling organisms to an adjacent barge or
shore-based facility for collection and processing. The waste stream is
processed by a separate service provider, not the vessel. As such, EPA
views these discharges as similar to the discharge of treated ballast
water from a barge-based or shore-based treatment facility, which are
not subject to regulation under the VIDA pursuant to CWA section
312(p)(9)(C). In-water cleaning without capture refers to any in-water
cleaning techniques that do not use a capture device.
Vessels following effective biofouling management strategies
generally should be able to maintain fouling at or below the
microfouling level. The final rule requires that hulls and niche areas
be managed to minimize biofouling, such as through preventative
cleaning of microfouling. 40 CFR 139.22(d)(2). Preventative in-water
cleaning, also referred to as proactive cleaning, is the frequent,
gentle cleaning of the vessel hull and appendages to prevent or reduce
the attachment and growth of macrofouling, with minimal impacts to the
anti-fouling system. Preventative cleaning of microfouling can have
many benefits, including but not limited to drag reduction, operations
enhancement, and reduced discharge of biofouling organisms. Studies
have estimated that even light microfouling can increase the drag on a
vessel by up to 25 percent (Townsin, 2003; Schultz, 2007). Predictive
analytics have shown that preventative cleaning reduces fuel
consumption and that increasing cleaning to an interval of
approximately six months can save hundreds of thousands of dollars in
annual fuel costs per vessel (Marr, 2017). Additionally, preventative
cleaning has been shown to effectively reduce biofouling without
significantly increasing biocide loading into the aquatic environment
(Tribou and Swain, 2017). However, one study of preventative in-water
cleaning showed elevated levels of copper directly above cleaning
brushes during cleaning (Scianni et al., 2023).
Monitoring the condition of hulls and niche areas and removal of
any biofouling identified is considered an industry best practice in
large part due to the economic incentive involved, as the costs
associated with regular in-water cleaning (namely, the cleaning
services, disruptions to a vessel's schedule, and staff time), are
outweighed by the fuel savings that result from managing vessel
biofouling at or below the microfouling level. As such, EPA finds that
preventative cleaning of microfouling represents BAT to control the
release of biofouling organisms and biocides from hulls and niche
areas, with likely long-term savings to the vessel industry.
The final rule prohibits any discharge from in-water cleaning
without capture of macrofouling. 40 CFR 139.22(d)(4). Removal of
macrofouling requires more abrasive techniques that may damage the
anti-fouling coating, resulting in increased likelihood of subsequent
biofouling, as well as a larger pulse of biocides and particles into
the aquatic environment. Furthermore, macrofouling is composed of more
diverse and reproductively mature organisms and, depending on
geographic origin, may present a greater risk of discharging biofouling
organisms than microfouling (Davidson et al., 2013; Morrisey et al.,
2013; Department of the Environment [DOE] and New Zealand Ministry for
Primary Industries [MPI], 2015). By effective preventative cleaning of
microfouling, cleaning in drydock when practicable, and other best
practices required in the final rule, vessels may minimize the need to
conduct in-water cleaning of macrofouling. In circumstances where such
cleaning is necessary, IWCC is available to vessels.
The final rule requires that hull and niche area cleanings must
minimize the damage to the anti-fouling coating, minimize the release
of biocides, and follow applicable cleaning requirements found on the
anti-fouling coating manufacturers' instructions and any applicable
FIFRA label. 40 CFR 139.22(d)(3). This is consistent with requirements
in the Uniform National Discharge Standards for Vessels of the Armed
Forces for underwater ship husbandry at 40 CFR 1700.37. These
requirements are considered best practices and ensure the longevity and
effectiveness of the anti-fouling coating, while minimizing pollutant
loading into the surrounding waters. Similar to the final standards for
deck washdowns in
[[Page 82118]]
this rule at 40 CFR 139.15(g), the final standards for hulls and
associated niche areas at 40 CFR 139.22(d)(7) require any soap,
cleaner, or detergent used on vessel surfaces, including but not
limited to the scum lines of the hull, to be minimally-toxic,
phosphate-free, and biodegradable.
40 CFR 139.22(d)(5) prohibits any discharge from in-water cleaning
without capture of any copper-based hull coatings in a copper-impaired
waterbody within the first 365 days after application of that coating.
The final rule also prohibits in-water cleaning without capture on any
section of an anti-fouling coating that shows excessive cleaning
actions (e.g., brush marks) or blistering due to internal failure of
the paint system. 40 CFR 139.22(d)(6). Such a level of deterioration
indicates failure at the anti-corrosive/anti-fouling interface, which
is more likely to be broken by cleaning. The rupturing of paint
blisters results in discharges of anti-fouling coating particles and an
increased rate of damage to the anti-fouling system more generally. In
turn, the exposed surface is subject to increased fouling and risk of
corrosion. EPA expects that an anti-fouling system selected in
accordance with the vessel's operational profile and cleaned with
minimally abrasive cleaning methods should not present signs of
significant deterioration at the anti-corrosive/anti-fouling interface.
Therefore, adherence to this standard is achievable by following the
coating and cleaning practices in the final standards. In consideration
of implementation and enforcement challenges, the final rule excludes
the terms ``local in origin'' and ``plume or cloud of pain'' from the
proposed rule in regard to hull and niche area cleaning, but retains
the terms ``frequent,'' ``gentle,'' ``minimal,'' and ``minimize release
of biocides.''
The final rule stipulates that cleanings should take place in
drydock when practicable. at 40 CFR 139.22(d)(1). Drydock schedules
should be factored into the inspection and management of areas
susceptible to biofouling. EPA recognizes that it may not be
technologically available or economically achievable for a vessel to be
drydocked outside of the regular schedule to clean biofouling from the
hull or niche areas. For example, some vessels are too large to be
regularly removed from the water, and any repair or maintenance
required on the hull or niche areas must occur while the vessel is
pierside between drydockings. Several mechanisms are used by vessel
owners/operators to determine the necessary cleaning interval,
including regular inspections, ISO standard 19030 measurements of hull
and propeller performance, and/or advanced data analytics. Further,
many technologies are available for preventative in-water cleaning,
including diver-operated technologies or remotely operated vehicles. A
review of the market of hull cleaning robots sponsored by the USCG in
2016 identified no fewer than 15 technologies capable of conducting in-
water cleaning of vessel hulls. More recently, remotely operated
vehicles for preventative cleaning have also been developed as
equipment attached to the vessel itself, enabling flexibility in
cleaning schedules along a vessel's route.
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule prohibits the discharge
from in-water cleaning of vessel hulls and niche areas into federally-
protected waters except by any vessel owned or under contract with the
United States, State, or local government to do business exclusively in
any federally-protected waters. 40 CFR 139.40(i).
14. Inert Gas Systems
Inert gas is used on tankers for several reasons, with one of the
primary uses being to control the oxygen levels in the atmosphere of
cargo and ballast tanks to prevent explosion and suppress flammability.
Inert gas system discharges consist of scrubber washwater and water
from deck water seals when used as an integral part of the inert gas
system.
EPA was unable to identify new technology or best management
practice options for discharges from inert gas systems, therefore the
Agency relied on the BPT/BCT/BAT analysis underlying the VGP
requirements and is requiring substantively the same requirements
included in the VGP. 40 CFR 139.23. EPA did not receive any comments
suggesting revisions to the proposed standards. EPA did, however,
modify the structure of the requirements from the proposed rule to
clarify that while there are no additional discharge-specific
requirements applicable to inert gas systems, as with any discharge
incidental to the normal operation of vessel subject to regulation
under this part, discharges from inert gas systems must meet the
general discharge requirements in subpart B of this part.
15. Motor Gasoline and Compensating Systems
Motor gasoline compensating system discharge is the discharge of
seawater that is taken into motor gasoline tanks to replace the weight
of fuel as it is used and eliminates free space where vapors could
accumulate. The compensating system is used for fuel tanks to supply
pressure for the gasoline and to keep the tank full to prevent
potentially explosive gasoline vapors from forming. The seawater is
discharged when the vessel refills the tanks with gasoline or when
performing maintenance. The discharge can contain both toxic and
conventional pollutants including residual oils or traces of gasoline
constituents, which can include alkanes, alkenes, aromatics (e.g.,
benzene, toluene, ethylbenzene, phenol, and naphthalene), metals, and
additives. Most vessels by design do not produce this discharge.
EPA was unable to identify new technology or best management
practice options for discharges from motor gasoline compensating
system, therefore the Agency relied on the BPT/BCT/BAT analysis
underlying the VGP requirements and is requiring substantively the same
requirements included in the VGP with slight modifications for
consistency and clarity. 40 CFR 139.24. EPA did not receive any
comments suggesting revisions to the proposed requirements.
The final rule does not include additional discharge-specific
requirements applicable to motor gasoline compensating systems except
in federally-protected waters (40 CFR 139.24(b)), but as with any
discharge incidental to the normal operation of vessel subject to
regulation under this part, discharges from motor gasoline compensating
systems must meet the general discharge requirements in subpart B of
this part (including requirements set forth for oily discharges as
appropriate for the vessel).
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule requires several
additional controls for discharges from motor gasoline compensating
systems from a vessel operating in federally-protected waters. 40 CFR
139.40(j).
16. Non-Oily Machinery
Non-oily machinery wastewater is the combined wastewater from the
operation of distilling plants, water chillers, valve packings, water
piping, low- and high-pressure air compressors, propulsion engine
jacket coolers, fire pumps, and seawater and potable water pumps. Non-
oily machinery wastewater systems are intended to keep wastewater from
machinery that does
[[Page 82119]]
not contain oil separate from wastewater that has oil content. Non-oily
machinery wastewater discharge rates vary by vessel size and operation
type, ranging from 100 to 4,000 gallons per hour. Constituents of non-
oily machinery wastewater discharge can include a suite of conventional
and nonconventional pollutants including metals and organics.
EPA was unable to identify new technology or best management
practice options for discharges of non-oily machinery wastewater,
therefore the Agency relied on the BPT/BCT/BAT analysis underlying the
VGP requirements and is requiring substantively the same requirements
included in the VGP with minor modifications for clarity. 40 CFR
139.25. EPA did not receive any comments suggesting revisions to the
proposed requirements.
The final rule prohibits the discharge of untreated non-oily
machinery wastewater and packing gland or stuffing box effluent that
contains toxic or bioaccumulative additives, or the discharge of oil in
such quantities as may be harmful. 40 CFR 139.25(b).
17. Pools and Spas
Cruise ships and other vessels occasionally have freshwater or
seawater pools or spas onboard that use water treated with chlorine or
bromine as a disinfectant. When pools or spas are drained, the water is
discharged overboard or sent to an AWTS. The discharge water can
contain nonconventional pollutants such as bromine and chlorine.
EPA was unable to identify new technology or best management
practice options for discharges from pools and spas, therefore the
Agency relied on the BPT/BCT/BAT analysis underlying the VGP
requirements and is requiring substantively the same requirements
included in the VGP. 40 CFR 139.26. EPA determined the dechlorination
limits by using those established for BWMSs and by evaluating comments
submitted by the public on the 2008 and 2013 VGPs that indicated such
limits are achievable. Furthermore, the final numeric discharge
standard is consistent with common dechlorination limits from shore-
based sewage treatment facilities.
As such, the final pool and spa discharge standards are the same as
the proposed standards. The final rule requires vessel operators,
except for unintentional or inadvertent releases from overflows across
the decks and into overboard drains, to discharge while underway unless
determined to be infeasible, and dechlorinate and/or debrominate any
pool or spa water, prior to discharging overboard. 40 CFR 139.26(b). To
be considered dechlorinated, the total residual chlorine in the pool or
spa effluent must be less than 100 [micro]g/L. To be considered
debrominated, the total residual oxidant in the pool or spa effluent
must be less than 25 [micro]g/L.
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule requires additional
controls for discharges from pools and spas from vessels operating in
federally-protected waters. 40 CFR 139.40(k).
18. Refrigeration and Air Conditioning
Condensation from cold refrigeration or evaporator coils of air
conditioning systems drips from the coils and collects in drip troughs
that typically channel to a drainage system. The condensate discharge
may contain toxic, conventional, and nonconventional pollutants
including but not limited to detergents, seawater, food residue, and
trace metals. This waste stream can easily be segregated from oily
wastes and toxic or hazardous materials and safely discharged.
Condensation is generally directed overboard, or in some instances may
be collected for temporary holding until onshore disposal or otherwise
drained to the bilge.
EPA was unable to identify new technology or best management
practice options for refrigeration and air conditioning condensate,
therefore the Agency relied on the BPT/BCT/BAT analysis underlying the
VGP requirements and is requiring substantively the same requirements
included in the VGP. 40 CFR 139.27.
The final rule prohibits the discharge of refrigeration and air
conditioning condensate that contacts toxic or hazardous materials. 40
CFR 139.27(b). Any discharges from refrigeration and air conditioning
that are commingled with other discharges (e.g., through the bilge or
non-oily machinery) must meet the requirements for both discharges.
19. Seawater Piping
Seawater piping systems carry seawater to various locations onboard
the vessel via a network of pipes and pumps. This seawater is critical
to the proper functioning of a vessel and is used for activities such
ballasting and firefighting, as well as in a variety of systems (e.g.,
engines, hydraulics, cleaning equipment, refrigeration, toilet
systems). Based on comments received on the proposed rule, the final
rule includes a definition for ``seawater piping system.'' (See 40 CFR
139.2 definition of ``seawater piping system''). Some components of
seawater piping systems, including sea chests, sea inlet pipes, and
overboard discharges, are also considered niche areas (See 40 CFR
139.2, definition of ``niche areas''). Niche areas that are part of the
seawater piping system are subject to requirements at 40 CFR 139.22.
Seawater piping systems can harbor and discharge a large quantity
of biofouling organisms and represent a challenge for biofouling
management as they are generally more difficult to access. They are
also protected from hydrodynamic forces, facilitating the accumulation
and survivorship of biofouling organisms. Ensuring that seawater piping
systems are unobstructed by biofouling is vital to vessel operations,
including the structural integrity of the vessel and the safety of the
crew.
The final rule also requires that any vessel with a seawater piping
system that accumulates macrofouling must be fitted with a Marine
Growth Prevention System (MGPS). 40 CFR 139.28(c). The most common
MGPSs for seawater include sacrificial anodic copper systems and
chlorine-based dosing systems. These systems are already widely used
and available. EPA recognizes that there may be a variety of systems
capable of addressing biofouling in seawater piping systems, and an
effective, preventative biofouling management strategy may include a
combination of different systems (e.g., chemical injection;
electrolysis, ultrasound, ultraviolet radiation, or
electrochlorination; application of an anti-fouling coating; and use of
cupro-nickel piping). Additionally, based on comments received on the
proposed rule, the final rule includes glass-reinforced filament-wound
epoxy-based composite piping as an acceptable component of a MGPS. 40
CFR 139.28(c)(2)(v). EPA considers the operation and maintenance of an
MGPS to represent BAT for the control of biofouling organisms
associated with seawater piping systems due to the many options
available and the wide extent of their current use.
An MGPS can vary widely in operational characteristics and
placement suitability. The final rule requires that MGPS selection must
consider the level, frequency, and type of expected biofouling and the
design, location, and area in which the system will be used. 40 CFR
139.28(c)(1). For example, it has been suggested that an MGPS installed
in the sea chest provides protection to both the sea chest
[[Page 82120]]
and internal pipework, while one installed in the strainer may only
protect the internal pipework. Furthermore, anti-fouling coating
selection and application should be appropriate to the material of the
piping and level of waterflow to which the coated area is subjected.
Based on the potential differences in profile of the coated areas, the
anti-fouling coating applied to a seawater piping system may be
different from the anti-fouling coating applied to the vessel hull. EPA
recommends that the MGPS be selected, installed, and maintained
according to the manufacturer specifications.
Upon identification of macrofouling in the seawater piping system
despite preventative measures, reactive measures such as use of
physical cleaning devices must be used to remove biofouling; however,
discharges from reactive measures used to remove macrofouling are
prohibited in port. 40 CFR 139.28(c)(3). A vessel may use a separate
service provider to clean and capture wastes from the cleaning process
provided any discharges from those activities are managed pursuant to
other applicable legal authorities (e.g., CWA section 402), consistent
with 40 CFR 139.22. The frequency of inspection and identification of
macrofouling in a seawater piping system (and use of reactive measures
when macrofouling is present) will be vessel-specific, so the final
rule does not identify a specific time interval for such measures. Time
intervals should be determined based on a vessel's operational profile.
Seawater piping system discharges include non-contact engine
cooling water, hydraulic system cooling water, refrigeration cooling
water, and freshwater lay-up wastewater. Such systems use ambient
seawater to absorb the heat from heat exchangers, propulsion systems,
and mechanical auxiliary systems. The water is typically circulated
through an enclosed system that does not come in direct contact with
machinery, but still may contain sediment from water intake, traces of
hydraulic or lubricating oils, and trace metals leached or eroded from
the pipes within the system. Additionally, because it is used for
cooling, the effluent will have an increased temperature. Cooling water
can reach high temperatures with the thermal difference between
seawater intake and discharge typically ranging from 5 [deg]C to 25
[deg]C, with maximum temperatures reaching 140 [deg]C. The use of shore
power may reduce the discharges of seawater from cooling systems.
Because shore power may not be available in all locations, may not be
sufficient for the electricity needs of the vessel, and/or may not be
compatible with the vessel's systems, the final rule does not require
the use of shore power to reduce thermal discharges from seawater
piping systems although EPA does recommend the use of shore power when
available and feasible for vessel use.
Based on comments received on the proposed rule, the final rule
includes a new 40 CFR 139.28(b) requiring that seawater piping systems
must be inspected, maintained, and cleaned as necessary to minimize the
accumulation and discharge of biofouling organisms. EPA added this
requirement as a BMP that is reasonably necessary to carry out the
purpose of reducing and eliminating the discharge of pollutants.
Inspection and maintenance, with occasional cleaning as necessary, is
technologically available and economically achievable. As discussed in
section VII. of this preamble, Definitions, the final rule dispenses
with the use of the Navy Fouling Rating scale employed in the proposed
rule in favor of the term ``macrofouling'' to identify fouling that had
been designated as FR-20 in the proposed rule.
Finally, as discussed in section VIII.C. of this preamble,
Discharges Incidental to the Normal Operation of a Vessel--Federally-
Protected Waters Requirements, the final rule requires controls for
discharges seawater piping systems from vessels operating in federally-
protected waters. 40 CFR 139.40(l).
20. Sonar Domes
Sonar dome discharge consists of leachate from anti-fouling
materials into the surrounding seawater and the discharge of seawater
or freshwater retained within the sonar dome. Sonar domes house
detection, navigation, and ranging equipment and are filled with water
to maintain their shape and pressure. They are typically found on
research vessels but may be present on other vessel classes. Sonar dome
discharge occasionally occurs when the water in the dome is drained for
maintenance or repair, and discharge rates are estimated to range from
300 to 74,000 gallons from inside the sonar dome for each repair event.
This discharge from inside the dome may include toxic pollutants
including zinc, copper, nickel, and epoxy paints. Additionally,
discharge occurs when materials leach from the exterior of the dome.
Components that may leach into surrounding waters include anti-fouling
agents, plastic, iron, and rubber.
EPA was unable to identify new technology or best management
practice options for discharges from sonar domes, therefore the Agency
relied on the BPT/BCT/BAT analysis underlying the VGP requirements and
is requiring substantively the same requirements included in the VGP.
40 CFR 139.29. EPA did not receive any comments suggesting revisions to
the proposed requirements.
The final rule prohibits the discharge of water from inside the
sonar dome during maintenance or repair. 40 CFR 139.29(b). The final
rule also prohibits the discharge of bioaccumulative biocides from the
exterior of the sonar dome when non-bioaccumulative alternatives are
available. 40 CFR 139.29(c).
C. Discharges Incidental to the Normal Operation of a Vessel--
Federally-Protected Waters Requirements
CWA section 312(p)(4)(B)(iii) specifies that, with limited
exceptions, EPA must establish Federal standards of performance that
are no less stringent than the VGP requirements relating to effluent
limits and related requirements, including with respect to waters
subject to Federal protection, in whole or in part, for conservation
purposes. Therefore, the final rule prohibits or limits discharges in
federally-protected waters consistent with the VGP requirements
established for ``waters federally-protected for conservation
purposes.'' 40 CFR 139.40.
The final rule includes several updates to these VGP requirements.
EPA determined that these new requirements are technologically
available because the scope of waters to which the requirements would
apply are limited, such that vessels are able to operate while
restricting their discharges in these protected waters. For example, a
vessel traveling through the Florida Keys National Marine Sanctuary can
ordinarily wait to discharge accumulated water and sediment from any
chain locker or chemically-dosed seawater piping until no longer in
those federally-protected waters. EPA determined that the requirement
is economically achievable because EPA does not have any information
indicating that vessels undertaking an activity such as holding the
discharge until it is no longer in federally-protected waters would
incur costs.
1. Identification of Federally-Protected Waters
The designated federally-protected waters for this rulemaking
include National Marine Sanctuaries, Marine National Monuments,
National Parks, National Wildlife Refuges, National Wilderness Areas,
or parts of the National Wild and Scenic Rivers
[[Page 82121]]
System, consistent with the categories of waters listed in appendix G
of the VGP. These VGP categories were based on EPA's review of several
Federal authorities that protect waters that are known to be of high
value or sensitive to environmental impacts, such as those administered
by the Bureau of Land Management (BLM), the National Park Service
(NPS), the U.S. Fish and Wildlife Service (FWS), the Forest Service
(USFS), and the National Oceanic and Atmospheric Administration (NOAA).
Consistent with CWA section 312(p)(9)(E), the requirements of this part
(40 CFR part 139) are in addition to any requirements established by
the Secretary of Commerce or the Secretary of the Interior to
administer any land or waters under their administrative control (e.g.,
National Marine Sanctuaries Act requirements applicable to these areas
established pursuant to 16 U.S.C. 1431 et seq.; 15 CFR part 922; 50 CFR
part 404).
Federally-protected waters are likely to be of high quality and
consist of unique ecosystems that may include distinctive species of
aquatic animals and plants. Furthermore, as protected areas, these
waters are more likely to have a greater abundance of sensitive species
of plants and animals that may have difficulty surviving in areas with
greater anthropogenic impact. Such waters are important to the public
at large, as evidenced by the waters' special status or designation by
the Federal Government as National Marine Sanctuaries, Marine National
Monuments, National Parks, National Wildlife Refuges, National
Wilderness Areas, or parts of the National Wild and Scenic Rivers
System. The areas considered to be federally-protected waters are as
follows:
National Marine Sanctuaries--as designated under the
National Marine Sanctuaries Act (16 U.S.C. 1431 et seq.) and
implementing regulations found at 15 CFR part 922 and 50 CFR part 404.
EPA retrieved this information from https://sanctuaries.noaa.gov/visit/#locations on 5/1/2024.
Marine National Monuments--as designated by presidential
proclamation under the Antiquities Act of 1906 (54 U.S.C. 320301 et
seq.). EPA retrieved this information from https://www.fisheries.noaa.gov/pacific-islands/habitat-conservation/marine-national-monuments-pacific and https://www.fisheries.noaa.gov/new-england-mid-atlantic/habitat-conservation/northeast-canyons-and-seamounts-marine-national on 5/13/24.
National Parks (including National Preserves and National
Monuments)--as designated under the National Park Service Organic Act,
as amended (54 U.S.C. 100101 et seq.) within the National Park System
by the NPS within the U.S. Department of the Interior. EPA retrieved
this information from https://www.nps.gov/aboutus/national-park-system.htm on 5/6/2024.
National Wildlife Refuges (including Wetland Management
Districts, Waterfowl Production Areas, National Game Preserves,
Wildlife Management Area, and National Fish and Wildlife Refuges)--as
designated under the National Wildlife Refuge System Administration Act
of 1966 as amended by the National Wildlife Refuge System Improvement
Act of 1997 (16 U.S.C. 668dd et seq.). EPA retrieved this information
directly from USFWS, 5/10/2024; See also https://www.fws.gov/our-facilities.
National Wilderness Areas--as designated under the
Wilderness Act of 1964 (16 U.S.C. 1131 et seq.). Section 4(c) of the
Wilderness Act strictly prohibits motorized vehicles, vessels,
aircrafts or equipment for the purposes of transport of any kind within
the boundaries of all wilderness areas (16 U.S.C. 1133(c)). Exceptions
to this Act include motorized vehicle use for the purposes of gathering
information on minerals or other resources; for the purposes of
controlling fire, insects, or disease; and in wilderness areas where
aircraft or motorized boat use have already been established prior to
1964. EPA retrieved this information from https://wilderness.net/practitioners/wilderness-areas/search.php#resultsSection on 4/22/2024.
National Wild and Scenic Rivers--as designated under the Wild and
Scenic Rivers Act of 1968 (16 U.S.C. 1271 et seq.). EPA retrieved this
information from https://www.rivers.gov/river-miles on 4/22/2024.
EPA does not consider Outstanding National Resource Waters (ONRWs)
as federally-protected waters for purposes of this rule, as these are
State or Tribal water quality-based designations under the
antidegradation policy of the CWA. By contrast, CWA section
312(p)(4)(B)(iii) requires EPA to promulgate regulations that are no
less stringent than the VGP with respect to ``waters subject to Federal
protection'' (emphasis added). In excluding ONRWs from the list of
waters subject to Federal protection in the final rule even though such
waters were considered federally-protected under the VGP, EPA finds
that it made a material technical mistake or misinterpretation of law
when it required protection of ONRWs as ``Waters Federally Protected
Wholly or in Part for Conservation Purposes'' under the VGP.
EPA solicited comments on the use of the VGP's appendix G, and the
proposed rule's equivalent appendix A, as the list of federally-
protected waters. EPA updated the list of appendix A in the final rule
based on information available from Federal agencies at the time of
this public notice, as specified above. In response to commenter
concerns regarding the usability of the list in appendix A,
particularly for operators unfamiliar with U.S. federally-protected
waters, EPA added an asterisk (``*'') modifier to denote those
federally-protected waters that may be most relevant to vessels
regulated under this rule. However, EPA reiterates that 40 CFR 139.40
remains applicable to all federally-protected waters listed in appendix
A. Specific areas in appendix A were marked with an asterisk if they
were within 0.1 mile of the coast or Great Lakes, or within 0.5 miles
of National Waterway Network lines (DOT, 2024). Methodology for this
analysis is available in the docket. While this approach may not
perfectly correspond with areas where vessels do not/do transit, it can
assist the regulated community, particularly international operators
who may be less familiar with U.S. waterways, to identify federally-
protected waters that they may be most likely to transit, while
maintaining the level of stringency from the VGP.
The final appendix A was also modified to address both public and
interagency comments to remove several National Marine Sanctuaries that
are protected solely for cultural or historical purposes, rather than
marine resource conservation purposes, and for which there is no
evidence that discharges from vessels subject to this rule would
threaten these resources (i.e., Thunder Bay, Mallows Bay, Potomac
River, Monitor, Wisconsin Shipwreck, and Lake Ontario NMS). Excluding
waters that are protected solely for cultural or historical purposes
and not for marine resource conservation purposes is consistent with
the requirement that EPA's regulations continue VGP requirements to
protect waters subject to Federal protection ``for conservation
purposes.'' 33 U.S.C. 1322(p)(4)(B)(iii)(I). Such exclusion is also
consistent with the National Marine Sanctuaries Act, as some federally-
protected waters regulations are narrowly tailored to protect
shipwrecks and other resources. For these areas, NOAA specifically
chose not to regulate vessel discharges because it found no evidence
that discharges would threaten the cultural or historical resources.
[[Page 82122]]
EPA also received comments related to the applicability of the VIDA
to federally-protected waters outside of 12 NM. The VIDA (and by
extension this rule) is only applicable within waters of the United
States or waters of the contiguous zone (12 NM under Article 24 of the
Convention of the Territorial Sea and the Contiguous Zone). Therefore,
EPA removed the following three sanctuaries from appendix A that are
located fully outside of these waters: Flower Garden Banks, Grey's
Reef, and Monitor National Marine Sanctuaries. For federally-protected
waters that contain portions that are subject to the VIDA but also
extend outside of waters subject to the VIDA (e.g., Stellwagen Bank
National Marine Sanctuary; Florida Keys National Marine Sanctuary;
Papah[amacr]naumoku[amacr]kea Marine National Monument), the standards
promulgated here only apply to the portion of federally-protected
waters within 12 NM.
2. Discharge-Specific Requirements in Federally-Protected Waters
The final rule includes specific requirements for discharges into
federally-protected waters, as listed in appendix A and consistent with
CWA section 312(p)(4)(B)(iii). These requirements are in addition to
any applicable general or specific discharge requirements in subparts B
and C. EPA specifically solicited comments on the additional discharge
requirements proposed for vessels operating in federally-protected
waters. Commenters generally expressed support for the federally-
protected waters requirements except for certain discharges from
vessels that operate exclusively in federally-protected waters. To
address these concerns, the final rule identifies exclusions for
vessels operating exclusively within federally-protected waters for
discharges from ballast tanks, decks, fire protection equipment, and
hulls and associated niche areas in 40 CFR 139.40(b), (f), (g) and (i),
respectively. The additional requirements for vessels operating in
federally-protected waters are described in the following paragraphs
and are generally consistent with the relevant section(s) of the VGP
and based on a similar BAT finding that these requirements are
technologically available and economically achievable and do not have
any unacceptable non-water quality environmental impacts, including
energy requirements.
Ballast Tanks (40 CFR 139.40(b)): The discharge or uptake of
ballast water must be avoided in federally-protected waters, with
certain exceptions. This requirement does not apply to a vessel
operating within the boundaries of any National Marine Sanctuary that
preserves shipwrecks or maritime heritage in the Great Lakes unless the
designation documents for the sanctuary do not allow taking up or
discharging ballast water in such sanctuary, pursuant to section 610 of
the Howard Coble Coast Guard and Maritime Transportation Act of 2014 as
amended by the Coast Guard Reauthorization Act of 2015. Based on
comments received which provided new information on feasibility of the
proposed rule, the final rule exempts any vessel that operates solely
in a federally-protected water within a single COTP Zone from the
discharge prohibition in federally-protected waters. Because they don't
leave federally-protected waters, such vessels have no feasible way of
discharging outside these areas, and ballast water discharge is a
necessary part of normal vessel operations. This exemption is
consistent with a comparable single COTP Zone ballast water exclusion
applicable in other, non-federally-protected waters. Additionally, as
described in the proposed rule (85 FR 67818, October 26, 2020, section
VIII.B.1.i), this requirement does not apply beyond the boundaries of a
federally-protected water. While the VGP required avoidance of uptake
or discharge into waters that ``may directly affect'' federally-
protected waters, EPA did not include this expanded affected area as
applied in the VGP because information needed to make a determination
regarding a potential direct affect is highly dependent on the specific
instant at which a ballast water uptake or discharge event is to occur,
is not readily available, and is not easily characterized. This
determination was based on new information on feasibility from
commenters. As practical guidance for vessel operators that can delay a
ballast water discharge (e.g., an exchange) until the vessel is further
away from federally-protected waters, EPA recommends that the discharge
or uptake of ballast water be conducted as far from federally-protected
waters as possible.
Bilges (40 CFR 139.40(c)): The discharge of bilgewater into
federally-protected waters is prohibited from any vessel of 400 GT and
above.
Boilers (40 CFR 139.40(d)): Any discharge from a boiler into
federally-protected waters is prohibited. This requirement
acknowledges, however, that small volumes of routine blowdown may be
discharged, including from boilers that are designed and operated to
blowdown automatically, if preventing such discharge would compromise
the safety of life at sea pursuant to 40 CFR 139.1(b)(3).
Chain Lockers (40 CFR 139.40(e)): The discharge of accumulated
biological organisms, water, and sediment from any chain locker into
federally-protected waters is prohibited. Cleanout of chain lockers can
be scheduled when a vessel is outside of protected waters. This
prohibition does not mean that vessels should avoid rinsing their
anchor chain in federally-protected waters after they have been
anchored there, as generally required by 139.14(b) (``Anchors and
anchor chains must be rinsed of biofouling organisms and sediment when
the anchor is retrieved'').
Decks (40 CFR 139.40(f)): The discharge of deck washdown into
federally-protected waters is prohibited; however, the final rule
exempts any vessel operating exclusively within federally-protected
waters. As commenters noted, deck washdown is part of necessary
maintenance for these vessels. Additionally, while the VGP extended
this requirement to only large ferries (see VGP Part 5.3), the final
rule applies it to all vessels (except those exempted) because deck
washdowns for all vessels (except those exempted) can be scheduled when
a vessel is outside of protected waters.
Fire Protection Equipment (40 CFR 139.40(g)): Several commenters
expressed concerns regarding compliance with USCG fire drill
requirements and anchor chain washdown requirements in 40 CFR 139.14 of
the proposed rule, which both result in the discharge of water from
fire protection equipment. The VGP allowed anchor chain wash down from
the firemain in federally-protected waters to comply with wash down
requirements, but did not include any specifics for meeting USCG fire
drill requirements. EPA has determined that the ability to discharge
water to comply with USCG fire drill requirements is necessary to
maintain safety and prevent loss of life at sea. Based on the
requirements of the VGP and new information provided through comments
on the proposed rule, the discharge from fire protection equipment into
federally-protected waters is prohibited except to comply with USCG
fire drill requirements or anchor and anchor chain requirements in 40
CFR 139.14. When USCG fire drills are required, only vessels owned or
under contract with the United States, a State, or a local government
to do business exclusively in any federally-protected waters may
discharge firefighting foam into federally-protected waters. 40 CFR
139.19 already prohibits the use of
[[Page 82123]]
fluorinated firefighting foam in waters subject to this rule, with few
exceptions.
Graywater Systems (40 CFR 139.40(h)): The discharge of graywater
into federally-protected waters is prohibited from any vessel with
remaining available graywater storage capacity.
Hulls and Associated Niche Areas (40 CFR 139.40(i)): The discharge
from in-water cleaning of vessel hulls and niche areas into federally-
protected waters is prohibited; however, the final rule exempts any
vessel operating exclusively within federally-protected waters to
address commenters' concerns regarding necessary maintenance. Other
than for vessels that operate exclusively within federally-protected
waters, in-water cleaning of vessel hulls and niche areas can be
scheduled when the vessel is outside of protected waters.
Motor Gasoline and Compensating Discharge (40 CFR 139.40(j)): The
discharge of motor gasoline and compensating discharges into federally-
protected waters is prohibited.
Pools and Spas (40 CFR 139.40(k)): The discharge of pool or spa
water into federally-protected waters is prohibited. This prohibition
includes all discharges of pool or spa water regardless of chemical
concentrations, including seawater pools. While the VGP requirement was
only for medium and large cruise ships, the final rule extends it to
all vessels with pools or spas because for all vessels with pools and
spas these discharges can be scheduled when the vessel is outside of
protected waters.
Seawater Piping Systems (40 CFR 139.40(l)): The discharge of
chemical dosing, as required in 40 CFR 139.28, into federally-protected
waters is prohibited. Chemical dosing and the resultant discharge can
be scheduled when the vessel is outside of protected waters.
D. Discharges Incidental to the Normal Operation of a Vessel--Previous
VGP Discharges No Longer Requiring Control
The final rule excludes fish hold effluent and small boat engine
wet exhaust as independent discharges incidental to the normal
operation of a vessel. A fish hold is the area where fish are kept once
caught and kept fresh during the remainder of the vessel's voyage
before being offloaded to shore or another tender vessel. The fish hold
is typically a refrigerated seawater holding tank, where the fish are
kept cool by mechanical refrigeration or ice. With the exception of
ballast water, CWA section 312(p)(2)(B)(i)(III) excludes from these
final regulations discharges incidental to the normal operation of a
fishing vessel; therefore, although this discharge was included in the
VGP, it is not a discharge incidental to the normal operation of a
vessel subject to these regulations.
Small boat engines use ambient water that is injected into the
exhaust for cooling and noise reduction purposes. Similar to fishing
vessels, with the exception of ballast water, CWA section
312(p)(2)(B)(i)(III) excludes from these final regulations discharges
incidental to the normal operation of a vessel less than 79 feet;
therefore, although this discharge was included in the VGP, it is not a
discharge incidental to the normal operation of a vessel subject to
these regulations.
IX. Procedures for States To Request Changes to Standards, Regulations,
or Policy Promulgated by the Administrator
A. Petition by a Governor for the Administrator To Establish an
Emergency Order or Review a Standard, Regulation, or Policy
Under CWA section 312(p)(7)(A), a Governor of a State may submit a
petition to the Administrator to either (1) issue an emergency order;
or (2) review any standard of performance, regulation, or policy
promulgated under that section if there exists new information that
could reasonably result in a change. The final rule requires that such
a petition be signed by the Governor (or a designee) and include the
purpose of the petition (request for emergency order or review of any
standard of performance, regulation, or policy); any applicable
scientific or technical information that forms the basis of the
petition; and the direct and indirect benefits if the requested
petition were to be granted by the Administrator.
In issuing an emergency order under CWA section 312(p)(4)(E), the
statute directs EPA to consider the risk of introduction or
establishment of an ANS or the adverse effects of a discharge that
contributes to a violation of a water quality requirement. As such, EPA
is not requiring that a petition for an emergency order include
submission of direct and indirect cost information due to the statute's
directive to consider risk reduction and the protection of
environmental quality. Before issuing an emergency order, CWA section
312(p)(4)(E)(ii) requires the Administrator to request written
concurrence from the Secretary. Should the Secretary fail to concur
within 60 days of the request, the Administrator may issue the order
but must include in the administrative record documentation of the
request and a response to any written objections received from the
Secretary.
To review any standard, regulation, or policy, on the other hand,
EPA is requiring that a petition include the costs to the affected
classes, types, and/or sizes of vessels if the petition were granted.
40 CFR 139.50(b)(4). This is because, in setting a standard under the
VIDA, EPA must comply with all other applicable provisions of CWA
section 312(p), which includes setting standards based on BPT, BCT, and
BAT. This includes a consideration of economic achievability.
After considering the information provided in the petition and
other factors, as appropriate and based on EPA's discretion, the
Administrator shall grant or deny the petition. If granted, the
Administrator will either issue the relevant emergency order for a
petition to issue an emergency order (40 CFR 139.50(d)(1)), or submit a
Notice of Proposed Rulemaking to the Federal Register for comment for a
petition to review any standard of performance, regulation, or policy
(40 CFR 139.50(d)(2)).
EPA solicited comments on the proposed process for Governors to
petition for the issuance of an emergency order or to review any
standard of performance, regulation, or policy, including whether a
more detailed process should be developed. Based on comments received
on the proposed rule, the final rule utilizes the 180-day and one-year
statutory timeframes associated with responding to a petition for
issuance of an emergency order or to review any standard, regulation,
or policy, respectively. 40 CFR 139.50(c). The final rule also includes
an additional information requirement for petitions to review any
standard of performance, regulation, or policy. Namely, a petition must
identify the anticipated costs if the requested petition were to be
granted by EPA. 40 CFR 139.50(b)(4). As explained earlier in this
section, this is in keeping with the fact that the VIDA directs EPA to
apply the CWA technology-based standards for BPT, BCT, and BAT when
developing Federal standards of performance. These CWA standards
require the Agency to account for the projected cost of achieving
pollution reductions. Finally, EPA fixed a minor typographical error
that was present in the proposed rule; the final rule correctly
references CWA section 312(p)(4)(E), not 312(p)(4)(e), in 40 CFR
139.50(a)(1).
[[Page 82124]]
B. Petition by a Governor for the Administrator To Establish Enhanced
Great Lakes System Requirements
CWA section 312(p)(10)(B) identifies a process for establishing
enhanced Federal standards or requirements to apply within the Great
Lakes System in lieu of any comparable standards or requirements
promulgated under CWA section 312(p)(4)-(5). CWA section
312(p)(10)(B)(i)-(ii) provides that any Governor of a Great Lakes State
(or the Governor's designee) may initiate the process by submitting a
petition for an enhanced standard of performance or other requirement
to the Governor of each of the other Great Lakes states, the Executive
Director of the Great Lakes Commission, and the Director of EPA's Great
Lakes National Program Office proposing that other Governors of the
Great Lakes states endorse the petition. The final rule incorporates
the requirements at CWA section 312(p)(10)(B)(iii)(I)(bb) that a
petition shall include an explanation regarding why the applicable
standard of performance or other requirement is (1) at least as
stringent as a comparable standard of performance or other requirement
in the final rule; and (2) in accordance with maritime safety and
applicable maritime and navigation laws and regulations. 40 CFR
139.51(b). After following the applicable statutory procedures, CWA
section 312(p)(10)(B)(iii)(I)(aa) provides that the Great Lakes
Governors may jointly submit to the Administrator and the Secretary an
endorsement of a proposed standard of performance or other requirement
to apply within the Great Lakes System. CWA section
(p)(10)(B)(ii)(III)(bb) requires that any proposed standard or other
requirement must be endorsed by all Great Lakes Governors if the
proposal would impose any additional equipment requirement on a vessel,
or at least five Great Lakes Governors if the proposal would not impose
any additional equipment requirement on a vessel.
Upon receipt of the proposed standard of performance or requirement
from a Great Lakes Governor, CWA section 312(p)(10)(B)(iii)(II)
provides that the Administrator and the Secretary must sign for
publication in the Federal Register a joint notice that provides an
opportunity for public comment on the proposed standard of performance
or requirement. Pursuant to CWA section 312(p)(10)(B)(iii)(III)(aa), as
soon as practicable after publication of the joint notice, the
Administrator shall commence a review of the proposed standard of
performance or requirement to determine if it is at least as stringent
as the comparable CWA section 312(p) standards and requirements, while
the Secretary concurrently reviews to determine whether the proposed
standard of performance or requirement is in accordance with maritime
safety and applicable maritime and navigation laws and regulations.
During review, pursuant to CWA section 312(p)(10)(B)(iii)(III)(bb), the
Administrator and the Secretary shall consult with the Governor of each
Great Lakes State and representatives from the Federal and provincial
governments of Canada; shall take into consideration any relevant data
or public comments received; and shall not take into consideration any
preliminary assessment by the Great Lakes Commission or dissenting
opinion submitted by a Governor of a Great Lake State except to the
extent that such an assessment or opinion is relevant to the criteria
for the applicable determination under CWA section
312(p)(10)(B)(iii)(III)(aa). CWA section 312(p)(10)(B)(iii)(IV)
provides that not later than 180 days after receipt of the proposed
standard of performance or requirement, the Administrator and the
Secretary shall (1) approve or disapprove the proposal; and (2) submit
to the Governor of each Great Lakes State, and issue in the Federal
Register, a notice of the determination. Under CWA section
312(p)(10)(B)(iii)(V), if the proposal is disapproved, the
Administrator and Secretary shall sign and submit a notice of
determination to the Federal Register for publication that describes
the reasons why the standard of performance or requirement is less
stringent or inconsistent with applicable maritime safety or maritime
navigational laws and regulations, and provide any recommendations for
modifications that the Great Lakes states could make to conform the
disapproved portion of the proposal to the applicable requirements.
Under CWA section 312(p)(10)(B)(iii)(VI), if the Administrator and
Secretary approve a proposed standard of performance or other
requirement, the Administrator shall establish, by regulation, the
proposed standard or requirement within the Great Lakes in lieu of any
comparable standard or other requirements promulgated under CWA section
312(p)(4), and the Secretary shall establish, by regulation, any
requirements necessary to implement, ensure compliance with, and
enforce any new standard or requirement promulgated pursuant to this
petition process, or to apply the proposed requirement, within the
Great Lakes System in lieu of any comparable requirement promulgated
under paragraph CWA section (312)(p)(5).
EPA solicited comments on the process to request enhanced Great
Lakes system requirements, including the extent to which EPA should
provide further details in the final rule considering language already
included in the VIDA. Based on comments received on the proposed rule
and to improve clarity, EPA both replaced and added language in the
regulations to mirror the VIDA statutory language more closely. This
includes adding an additional provision that speaks to the timing and
effect of a Governor's withdrawal of an endorsement for a proposed
standard (40 CFR 139.51(f)), as well as a clarification that a complete
prohibition of one or more discharges only applies to those waters of
states with Governors endorsing the prohibition (40 CFR 139.51(k)). EPA
received one comment that led to a reexamination of the provision
dealing with judicial review and determined that, because the statute
speaks for itself on this matter, it does not require repetition in the
regulations and was therefore removed. EPA also made minor
modifications to the standards to improve consistency between related
paragraphs, add statutorily identified timeframes for the petition
process, and fix minor typographical errors in CWA references.
C. Application by a State for the Administrator To Establish a State
No-Discharge Zone
Under CWA section 312(p)(10)(D), states have the opportunity to
apply to EPA to prohibit one or more discharges incidental to the
normal operation of a vessel, whether treated or not, into specified
waters, if the State determines that the protection and enhancement of
the quality of some or all its waters require greater environmental
protection.
Pursuant to CWA section 312(p)(10)(D)(ii), a discharge prohibition
established by EPA through regulation would not apply until the date
the Administrator makes a determination as described in paragraph (iii)
establishing that (1) the prohibition would protect and enhance the
quality of the specified waters; (2) adequate facilities for the safe
and sanitary removal of the discharge incidental to the normal
operation of a vessel are reasonably available for the waters to which
the prohibition would apply; and (3) the discharge can safely be
collected and stored until a vessel reaches a discharge facility or
other location. If the no-discharge zone (NDZ) concerns ballast water
discharges regulated under CWA
[[Page 82125]]
section 312(p), then the Administrator must also determine that
adequate facilities are reasonably available for vessels subject to the
proposed NDZ after considering, at a minimum, water depth, dock size,
pumpout capacity and flow rate, availability of year-round operations,
proximity to navigational routes, and the ratio of pumpout facilities
to vessels in operation in the specified waters, and that the
prohibition for ballast water discharges will not unreasonably
interfere with the safe loading and unloading of cargo, passengers, or
fuel.
CWA section 312(p)(9)(A)(v) provides Alaska the authority to
regulate the discharge of graywater within State waters from a
passenger vessel carrying 50 or more passengers. Pursuant to section
1410 of Title XIV, Certain Alaskan Cruise Ship Operations, Alaska may
petition EPA under CWA section 312(f) to prohibit the discharge of
graywater and sewage from cruise ships operating in some or all of the
waters of the Alexander Archipelago or the navigable waters of the
United States within the State of Alaska or within the Kachemak Bay
National Estuarine Research Reserve. For all other incidental
discharges and types of vessels subject to this rule, Alaska, as with
the rest of the states, must adhere to the application process
identified in the VIDA and these regulations.
The final rule is substantively similar to the proposed rule;
however, the final rule incorporates some modifications to improve and
clarify the application requirements and process and to address
comments received during the public comment period. The application
requirements are intended to ensure that the State applicant provides
sufficient information for EPA to make the necessary determination
identified in CWA section 312(p)(10)(D)(iii)(I) without undue delay.
EPA's experience with CWA section 312(f) sewage NDZs suggests that an
informed determination requires a detailed understanding of the
proposed waters and affected vessel population to ensure that the
discharge prohibition is both environmentally beneficial and
achievable. For example, EPA cannot make a determination as to the
adequacy and reasonable availability of facilities if the application
does not characterize the location and operational capabilities of each
facility. EPA does, however, recognize that certain information
requirements may not be static or otherwise readily available to the
State. Information provided by the State to fulfill these information
requirements in the application may be projections or estimates;
however, projections and estimates must be justified and explained in
the application.
The final rule identifies the information requirements for a
state's application and the key procedural steps associated with EPA
approval and USCG concurrence. Based on comments received, EPA made
adjustments to some of the requirements. Among other facility
characteristics identified in the proposed rule, the final rule
requires the state's application to include information on the
connections at each facility for offloading discharge(s) from vessels
to account for the design of vessels and the potential issue that
incompatible connections may pose for vessel access to facilities. 40
CFR 139.52(c)(5). To address transport concerns raised during the
comment period, the final rule incorporates a new application
requirement for the State to explain the wastewater handling procedures
of each facility. 40 CFR 139.52(c)(6). The purpose of this requirement
is to ensure that storage and transport of offloaded wastewater is
conducted safely and in conformance with applicable laws. This
information will also assist EPA in making a timely determination
regarding the adequacy of facilities for pumpout and treatment of the
wastewater, as required by the VIDA. The final rule also updates the
provision concerning the map of facility locations to allow a State to
provide the coverage area for mobile facilities in lieu of a specific
point location. 40 CFR 139.52(c)(7). EPA notes that some facility
characteristics identified as required in the final rule may not always
be relevant to mobile facilities. However, any pertinent restrictions
that may affect vessel access to the facility must be noted. At
commenters' request, EPA also added clarifying information in this
preamble regarding applicability of the NDZ program to graywater in
Alaska and the use of projections in the State application. To the
extent that commenters otherwise asked EPA to require additional
information in State NDZ applications, such requirements are
unnecessary for EPA to evaluate the applications for an NDZ under the
VIDA.
In light of comments received, EPA concluded that the requirement
for the application to include a table identifying the location and
geographic area of each proposed NDZ was unclear. Therefore, the final
rule instead includes a provision requiring a narrative explanation of
the location of the proposed waters and a map delineating the
boundaries of the requested prohibition using geographic coordinates.
40 CFR 139.52(c)(1). EPA has further concluded that the 40 CFR
139.52(h) provision from the proposed rule was not necessary to include
in the final rule because it repeated the contents of 40 CFR 139.52(b).
In 40 CFR 139.52(d)(2), EPA added that ``the availability of
operational changes as a means to reduce the discharge'' is another
factor considered in making an adequacy determination, because
operational changes may be available as an alternative to pumpout
facilities for certain discharges. Lastly, EPA made minor changes to
the standards to consistently refer to the state's submittal as an
``application,'' to emphasize that only existing facilities can be
considered as part of EPA's adequacy determination, and to simplify the
provisions related to the application process for clarity.
Regarding the application process, EPA notes that within 90 days of
receipt of an application from a State containing the required
information, EPA will send a determination letter to the applicant with
a tentative approval or disapproval. Following a tentative approval,
EPA will proceed through the rulemaking process, including issuance of
a Notice of Proposed Rulemaking and a request for concurrence from the
USCG. If appropriate after review of public comments, EPA will publish
a final rule establishing a prohibition. An NDZ will be enforced
according to CWA section 312(k) and will have an effective date 30 days
after publication of the final rule unless the State and EPA agree to a
later date. If EPA concludes that it is appropriate to disapprove the
application, either initially or after review of public comments on the
Notice of Proposed Rulemaking, EPA will notify the public of the
disapproval by publishing a notice in the Federal Register that
includes an explanation of EPA's decision-making.
X. Implementation, Compliance, and Enforcement
CWA section 312(p)(5) directs the USCG to develop implementing
regulations governing the design, construction, testing, approval,
installation, and use of marine pollution control devices as are
necessary to ensure compliance with the Federal standards of
performance presented in this final rule. Additionally, the USCG shall
promulgate requirements to ensure, monitor, and enforce compliance of
the final standards. As such, this final rule does not include
implementation, compliance, or enforcement provisions.
XI. Economic Analysis
An Economic Analysis (EA) was developed to accompany this final
rule.
[[Page 82126]]
In the EA, EPA projects that the incremental costs arising from the
final rule will be minor and that the vessel community will experience
a net savings of $11.3 million annually, based on $16.1 million of
annualized incremental costs and $27.4 million of annualized
incremental cost savings, at a two percent discount rate. The cost
savings are principally the result of the VIDA's exclusion of small
vessels and fishing vessels from Federal incidental discharge
requirements (e.g., CWA permits and national discharges standards),
except for ballast water. When compared to the VGP requirements, this
exclusion will reduce burden on more than 160,000 vessels. The EA
includes a qualitative discussion of benefits.
EPA estimates that 69,000 U.S.-flagged and 16,000 foreign-flagged
vessels will be subject to the discharge standards in this final rule.
The EA evaluates the cost impacts to the 69,000 U.S.-flagged vessels,
as well as the approximately 600 foreign-flagged vessels that are U.S.-
owned.
To estimate cost impacts, the EA uses compliance with the VGP and
the sVGP, as well as other regulations and industry standards, as the
analytic baseline because it represents the status quo that existed
prior to the passage of the VIDA. The analysis projected cost impacts
expected as a result of the final EPA standards compared to the
baseline experienced by the regulated community immediately prior to
passage of the VIDA legislation. The VIDA repealed the sVGP effective
immediately upon signature, while stipulating that VGP requirements are
to remain in place until the new VIDA program is fully in force and
effective. This analysis accounts for both the impacts of the final EPA
standards as well as the regulatory relief expected as a result of the
VIDA's exclusion of small vessels and fishing vessels from the
discharge requirements, except for ballast water, and the corresponding
repeal of the sVGP.
The cost analysis groups the final rule's major impacts into three
major categories: (1) costs due to rule provisions dictated by the
VIDA; (2) costs for rule provisions unchanged from the VGP; and (3)
other rule provisions (including changes from the VGP). The first
category--costs due to rule provisions dictated by the VIDA--include
those legislative changes mandated directly in the VIDA that give rise
to incremental costs to vessel owners/operators. These provisions
impose new ballast water requirements nationally, as well as regionally
in the Pacific Region and the Great Lakes. The estimated incremental
cost for vessels to meet these ballast water-related Congressionally-
mandated provisions is $5.5 million annually. There is also an
incremental cost associated with the State petition processes provided
for in the VIDA, estimated at $6 thousand annually based on expected
burden from information collection activities over the next three
years. The second category--costs for rule provisions unchanged from
the VGP--specifically addresses the final standard for oil-to-sea
interfaces, which clarifies that the scope of this discharge category
includes discharge of lubricants from equipment that extends overboard,
and vessels must therefore use EALs in equipment that extends overboard
as well as equipment with oil-to-sea interfaces below the waterline.
The economic analysis accompanying the 2013 VGP did not include a cost
estimate for EAL use on equipment that extends overboard, so this EA
rectifies that omission. EPA estimated an average annual incremental
cost of $5.7 million for this category. The final category discusses
other rule provisions including changes from the VGP. First, it
discusses the final standards that result in incremental costs compared
to existing VGP requirements. This includes the standards promulgated
for graywater systems and seawater piping systems for which incremental
costs are projected to increase by $2.7 million annually. This category
also discusses the costs of the new requirement for new Lakers to
install, operate, and maintain a BWMS that has been type-approved by
the USCG. The EA calculated the total annualized cost to be $2.2
million for the new Laker equipment standard. Finally, this category
discusses final standards that are not expected to result in
incremental costs compared to the VGP baseline because they are largely
consistent with the VGP and/or reflect practices already in place on
vessels as a result of other regulations and industry standards. These
include certain aspects of the standards for desalination and
purification systems, exhaust gas recirculation systems, fire
protection equipment, and hulls and associated niche area management.
The EA also characterizes the reduction in costs projected to
result from the VIDA's exclusion of small vessels and fishing vessels
from the discharge requirements, except for ballast water, and the
corresponding repeal of the sVGP. EPA estimates that this regulatory
relief will result in annual cost savings of about $27.4 million to the
vessel community. EPA did not evaluate the cost impacts from changes in
monitoring, reporting, inspection, or recordkeeping associated with the
USCG's authorities and responsibilities under the VIDA.
To evaluate the potential impact of the final rule on small
entities, EPA used a cost-to revenue test to evaluate potential
severity of economic impact on vessels owned by small entities. The
test calculates annualized pre-tax compliance cost as a percentage of
total revenues and uses a threshold of 1 and 3 percent to identify
entities that would be significantly impacted by this final rule. EPA
projects the potential impacts would not exceed these conventional
cost/revenue thresholds. In addition, the Agency completed estimates of
the paperwork burden associated with the final rule. These estimates
project the annualized paperwork burden on states that voluntarily
petition EPA for any one of the following: establishment of no-
discharge zones, review of Federal standards of performance, issuance
of emergency orders, and establishment of enhanced Great Lakes System
requirements.
EPA also assessed the environmental impacts from this final rule.
The Agency does not expect the final rule to change environmental
benefits significantly compared to those realized by the VGP. This is
because the 2013 VGP already includes requirements for incidental
discharges from the vessels subject to this rule, so the environmental
benefits derived from having discharge standards in place are a
significant part of the baseline. Additionally, the existing VGP
requirements are largely adopted as the new discharge standards in this
rule, in part due to the VIDA's requirement that EPA's standards be at
least as stringent as those requirements in the 2013 VGP, barring
certain specified exemptions. EPA notes that the VIDA exclusion of
small vessels and fishing vessels, except for ballast water, and the
corresponding repeal of the sVGP could potentially lead to a reduction
in environmental benefits to the extent that affected vessels no longer
adhere to practices previously required under the sVGP. In particular,
the EA examines possible losses in benefits from the elimination of the
sVGP discharge management requirements for bilgewater, graywater, and
anti-fouling hull coatings.
The EA updates and replaces the Regulatory Impact Analysis (RIA)
that was prepared alongside the proposed rule. Based on comments
received on the proposed rule, the EA includes a revised U.S. ferry
vessel estimate based on new sources identified by a commenter and
information available
[[Page 82127]]
from EPA's 2013 VGP electronic reporting system. The final EA is
available in the docket.
XII. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 14094: Modernizing Regulatory Review
This action is a ``significant regulatory action'' as defined in
Executive Order 12866, as amended by Executive Order 14094.
Accordingly, EPA submitted this action to the Office of Management and
Budget (OMB) for Executive Order 12866 review. Documentation of any
changes made in response to Executive Order 12866 review is available
in the docket. EPA prepared an analysis of the potential costs and
benefits associated with this action. This Economic Analysis is
available in the docket.
B. Paperwork Reduction Act (PRA)
The information collection activities in this rule have been
submitted for approval to the Office of Management and Budget (OMB)
under the PRA. The Information Collection Request (ICR) document that
EPA prepared has been assigned EPA ICR number 2605.02. You can find a
copy of the ICR in the docket for this rule, and it is briefly
summarized here. The information collection requirements are not
enforceable until OMB approves them.
This action, once implemented through corresponding USCG
requirements addressing implementation, compliance, and enforcement,
would impose an information collection burden to states under the PRA.
The action imposes a new information collection burden on states
seeking to petition EPA to establish different Federal standards of
performance including enhanced standards in the Great Lakes, issue
emergency orders, or establish no-discharge zones. EPA does not
anticipate an information collection burden on states until the USCG
has established final implementing requirements (required by the VIDA
as soon as practicable but not later than two years after the EPA
discharge standards proposed in this rulemaking are finalized). After
such time, the information collection burden relates to the voluntary
preparation and submission of petitions by states and is therefore an
intermittent activity.
The ICR submitted for approval to the OMB as part of this
rulemaking reflects an anticipated burden to states in the third year
of the three-year ICR cycle. This includes one petition of each type:
Modification of Federal standards of performance, issuance of emergency
orders, and establishment no-discharge zones. EPA does not expect
petitions for enhanced Great Lakes System requirements during this ICR
cycle. The type and level of detail of information that a State would
need to generate to petition EPA under CWA section 312(p) is most
analogous to the information prepared for an application to EPA under
the existing CWA section 312 ICR (OMB control number 2040-0187), which
includes State activities related to petitioning EPA for no-discharge
zones for sewage and discharges incidental to the normal operation of
vessels of the Armed Forces. For incidental discharges from vessels of
the Armed Forces, states may also petition EPA for a review of
standards. Because of the parallels in discharge types and State
activities, EPA used the burden estimates in the existing ICR to inform
the expected burden for this proposed rule. Looking ahead, EPA expects
that this new ICR will be combined with the existing CWA section 312
ICR (OMB control number 2040-0187) expected to be renewed no later than
September 30, 2026. This would create a single ICR that would include
the information collection burden for all three vessel programs under
CWA section 312 (sewage, vessels of the Armed Forces, and commercial
vessels).
The hour and cost estimates, summarized below, include such
activities as reviewing the relevant regulations and guidance
documents, gathering and analyzing the required information, and
preparing and submitting the application.
Respondents/affected entities: State governments (NAICS code
924110) are the only respondents to the data collection activities
described in this ICR.
Respondent's obligation to respond: Preparation and submission of a
petition is a voluntary action that may be undertaken by the
respondent. This is not a reporting requirement, nor are there any
deadlines associated with these petitions.
Estimated number of respondents: Three respondents are anticipated
during this three-year ICR cycle.
Frequency of response: Three petitions are anticipated during this
three-year ICR cycle, each in the third year, including one petition
each for establishment of a no-discharge zone; review of any standard
of performance, regulation, or policy; and issuance of an emergency
order.
Total estimated burden: Approximately 83 hours per year.
Total estimated cost: $5,604 per year, including $150 annualized
operation & maintenance costs.
An agency may not conduct or sponsor, and a person is not required
to respond to, a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for EPA's
regulations in 40 CFR are listed in 40 CFR part 9. When OMB approves
this ICR, the Agency will announce that approval in the Federal
Register and publish a technical amendment to 40 CFR part 9 to display
the OMB control number for the approved information collection
activities contained in this final rule.
C. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA.
Although this action will impose requirements on any small entity that
operates a vessel subject to the standards, EPA used a cost-to-revenue
test to evaluate the potential severity of economic impact on vessels
owned by small entities. EPA determined that the projected cost burden
would not exceed 1 percent of annual revenue. Details of the screening
analysis are presented in section 8.3 (``Regulatory Flexibility Act'')
in the Economic Analysis available in the docket.
D. Unfunded Mandates Reform Act (UMRA)
This action does not contain any unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. The action imposes no enforceable duty on any State,
local, or Tribal governments or the private sector.
E. Executive Order 13132: Federalism
EPA has concluded that this action has federalism implications
because it preempts State law. The VIDA added a new CWA section
312(p)(9)(A) that specifies that, beginning on the effective date of
the requirements promulgated by the Secretary established under CWA
section 312(p)(5), no State, political subdivision of a State, or
interstate agency may adopt or enforce any law, regulation, or other
requirement with respect to an incidental discharge subject to
regulation under the VIDA except insofar as such law, regulation, or
other requirement is identical to or less stringent than the Federal
regulations under the VIDA.
[[Page 82128]]
EPA provides the following federalism summary impact statement. EPA
consulted with State and local officials early in the process of
developing the proposed action to permit them to have meaningful and
timely input into its development. EPA and the USCG conducted a
Federalism consultation briefing on July 9, 2019, in Washington, DC to
allow for such input. EPA provided an overview of the VIDA, described
the interim requirements and the framework of future regulations,
identified State provisions associated with the VIDA, and received
comments and questions. The briefing was attended by representatives
from the National Governors Association, the National Conference of
State Legislatures, the U.S. Conference of Mayors, the County
Executives of America, the National Association of Counties, the
National League of Cities, Environmental Council of the States, the
Association of Clean Water Administrators, the National Water Resources
Association, the Association of Fish and Wildlife Agencies, the
National Association of State Boating Law Administrators, the Western
Governors Association, and the Western States Water Council. Pre-
proposal comments were accepted from July 9, 2019 to September 9, 2019
and are described in conjunction with the Governors' Consultation
comments. After the public comment period concluded, EPA met with state
representatives to discuss topics of interest between June and October
2021 to inform the development of the supplemental notice and final
rule.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action has Tribal implications. However, it will neither
impose substantial direct compliance costs on federally recognized
Tribal governments, nor preempt Tribal law. Tribes may be interested in
this action because commercial vessels may operate in or near Tribal
waters. Additionally, EPA may be authorized to treat eligible federally
recognized Tribes as a State (TAS) under section 309 of the CWA.
EPA consulted with Tribal officials under the EPA Policy on
Consultation and Coordination with Indian Tribes early in the process
of developing this regulation to permit them to have meaningful and
timely input into its development. A summary of that consultation and
coordination follows.
EPA initiated a Tribal consultation and coordination process for
EPA's 2020 Notice of Proposed Rulemaking (85 FR 67818, October 26,
2020) by sending a ``Notice of Consultation and Coordination'' letter
on June 18, 2019, to all 573 Tribes that were federally recognized at
the time.\8\ The letter invited Tribal leaders and designated
consultation representatives to participate in the Tribal consultation
and coordination process that lasted from July 11 to September 11,
2019. EPA held an informational webinar for Tribal representatives on
July 11, 2019, to obtain meaningful and timely input during the
development of the proposed rule. During the webinar, EPA provided an
overview of the VIDA, described the interim requirements and the
framework of future regulations, and identified Tribal provisions
associated with the VIDA. A total of nine Tribal representatives
participated in the webinar. EPA also provided an informational
presentation on the VIDA during the Region 10 Regional Tribal
Operations Committee (RTOC) call on July 18, 2019, as requested by the
RTOC. During the consultation period, Tribes and Tribal organizations
sent two pre-proposal comment letters to EPA as part of the
consultation process. In addition, EPA held one consultation meeting
with the leadership of a Tribe, at the Tribe's request, to obtain pre-
proposal input and answer questions regarding the forthcoming rule.
---------------------------------------------------------------------------
\8\ In December 2019, the Little Shell Tribe of Chippewa Indians
became the 574th federally recognized Tribe.
---------------------------------------------------------------------------
EPA incorporated the feedback it received from Tribal
representatives in the proposed rule. Records of the Tribal
informational webinar and a consultation summary of the written and
verbal comments submitted by Tribes are included in the public docket
for this rule. Several Tribes requested additional consultation in
comments submitted during the public comment period of the proposed
rule. EPA offered additional consultation opportunities and met with
Tribal representatives of the Gun Lake Tribe and Chippewa Ottawa
Resource Authority in September and October 2021, respectively, to
inform development of the supplemental notice and final rule.
As required by section 7(a), the EPA's Tribal Consultation Official
has certified that the requirements of the executive order have been
met in a meaningful and timely manner. A copy of the certification is
included in the docket.
G. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks
EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that EPA has reason to believe may disproportionately affect children,
per the definition of ``covered regulatory action'' in section 2-202 of
the Executive Order.
Therefore, this action is not subject to Executive Order 13045
because it does not concern an environmental health risk or safety
risk. Since this action does not concern human health, EPA's Policy on
Children's Health also does not apply. However, overall, this rule
would reduce the amount of pollution entering waterbodies from vessels
through the minimization and control of discharges entering the waters
of the U.S. and the contiguous zone that may contain pollutants such as
aquatic nuisance species (ANS), nutrients, bacteria or pathogens, oil
and grease, metals, as well as other toxic, nonconventional, and
conventional pollutants (e.g., organic matter, bicarbonate, and
suspended solids). This would yield human health benefits due to
decreased exposure to these pollutants and improve the recreational
utility of waterbodies where vessels would be subject to the proposed
standards.
H. Executive Order 13211: Actions That Concern Regulations That
Significantly Affect Energy Supply, Distribution, and Use
This action is not a ``significant energy action'' because it is
not likely to have a significant adverse effect on the supply,
distribution or use of energy. Any additional energy usage would be
insignificant compared to the total energy usage of vessels and the
total annual U.S. energy consumption. Additionally, given that the rule
establishes national standards of performance for vessel incidental
discharges, and that these standards are largely borne out of existing
requirements under the 2013 Vessel General Permit, EPA does not
anticipate any significant climate impacts.
I. National Technology Transfer and Advancement Act
This rulemaking does not involve technical standards. For
informational purposes, EPA notes the existence of voluntary standards
applicable to vessel activities developed by NACE; these standards
cover topics such as corrosion prevention and biofouling inspections.
[[Page 82129]]
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations and
Executive Order 14096: Revitalizing Our Nation's Commitment to
Environmental Justice for All
EPA believes that it is not practicable to assess whether the human
health or environmental conditions that exist prior to this action
result in disproportionate and adverse effects on communities with
environmental justice concerns. While EPA was unable to perform a
detailed environmental justice analysis because it lacks data on the
exact location of vessels and their associated discharges, the
rulemaking would increase the level of environmental protection for all
affected populations without having any disproportionately high and
adverse human health or environmental effects on any population,
including any minority or low-income population. The Agency recognizes
that the burdens of environmental pollution disproportionately fall on
certain communities with environmental justice concerns. Overall, this
rule would reduce the amount of pollution entering waterbodies from
vessels through the minimization and control of discharges entering the
waters of the U.S. and the contiguous zone that may contain pollutants
such as aquatic nuisance species (ANS), nutrients, bacteria or
pathogens, oil and grease, metals, as well as other toxic,
nonconventional, and conventional pollutants (e.g., organic matter,
bicarbonate, and suspended solids). This would yield human health
benefits due to decreased exposure to these pollutants and improve the
recreational utility of waterbodies where vessels would be subject to
the proposed standards.
The information supporting this Executive Order review is contained
in section III.C. of this preamble, Environmental Impacts of Discharges
for Which Technology-Based Discharge Standards Are Established by This
Rule, which provides information on the pollutants found in the vessel
discharges that this rule is intended to prevent or reduce from
entering waters of the United States or the contiguous zone. Section V.
of this preamble, Stakeholder Engagement, describes the public
participation opportunities associated with this rule that allowed for
meaningful and timely input on rule development and decision-making,
including any relevant environmental justice concerns.
K. Congressional Review Act (CRA)
This action is subject to the CRA, and EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is not a ``major rule'' as defined by 5
U.S.C. 804(2).

labeled, and secured containers located in areas of the vessel that
minimize exposure to ocean spray and precipitation consistent with
vessel design, unless the master determines this would interfere with
essential vessel operations or safety of the vessel or crew, or would
violate any applicable regulations that establish specifications for
safe transportation, handling, carriage, and storage of toxic or
hazardous materials.
(ii) Ensure containers holding toxic or hazardous materials are not
overfilled and incompatible materials (i.e., substances which, if
mixed, will create hazards greater than posed by the individual
substances) are not mixed.

the vessel's overboard discharge point with the exception that during
maneuvering and transit, the maximum difference of two pH units is
allowed between inlet water and overboard discharge values; or
(B) The pH discharge limit is the value that will achieve a minimum
pH of 6.5 at 4 meters from the overboard discharge point with the

determined at the overboard discharge monitoring point and is to be
recorded as the vessel's discharge limit. The overboard pH limit can be
determined either by means of direct measurement, or by using a
calculation-based methodology (computational fluid dynamics or other
[[Page 82140]]
equally scientifically established empirical formulas).
(ii) The pH numeric discharge standard may be exceeded for up to 15
minutes in any 12-hour period.
(2) PAHs (Polycyclic Aromatic Hydrocarbons).
(i) The maximum continuous PAH concentration in the discharge must
be no greater than 50 [micro]g/L PAHphe (phenanthrene equivalents)
above the inlet water PAH concentration. This standard applies
downstream of any washwater treatment equipment including any reactant
dosing unit but upstream of any seawater addition for control of pH
prior to discharge.
(ii) The 50 [micro]g/L numeric discharge standard is normalized for
a discharge flow rate, before any seawater neutralization for pH
control, of 45 tons (t)/megawatt-hour (MWh) where the mega-watt (MW)
refers to the Maximum Continuous Rating (MCR) or 80% of the power
rating of the fuel oil combustion units whose EGCS discharge water PAH
is being monitored at that point. In cases where sensors are installed
in a separate measurement cell, the PAH limit applies to the flow in
the main discharge pipe from which the water is bypassed. This numeric
discharge standard is adjusted upward or downward for different
discharge flow rates, pursuant to table 1 to paragraph (b)(2)(ii) of
this section.

(i) The washwater treatment system must be designed to minimize
suspended particulate matter, including but not limited to heavy metals
and ash.
(ii) The maximum continuous turbidity in the discharge must be no
greater than 25 FNU (formazin nephlometric units) or 25 NTU
(nephlometric turbidity units) or equivalent units above the inlet
water turbidity. However, to account for periods of high inlet
turbidity, readings must be a rolling average over a 15-minute period
to a maximum of 25 FNU or NTU. This standard applies downstream of any
washwater treatment equipment including any reactant dosing unit but
upstream of any seawater addition for control of pH prior to discharge.
(iii) For an aggregated 15-minute period in any rolling 12-hour
period, the continuous turbidity discharge limit may be exceeded by
20%.
(4) Nitrates plus nitrites:
(i) The washwater treatment system must prevent the discharge of
nitrates plus nitrites beyond that associated with a 12% removal of
NOX from the exhaust, or beyond 60 mg/L normalized for a
discharge rate of 45 tons/MWh, whichever is greater, where the MW
refers to the MCR or 80% of the power rating of all those fuel oil
combustion units whose EGCS discharge water nitrates plus nitrites are
being monitored at that point. This standard applies downstream of any
washwater treatment equipment including any reactant dosing unit but
upstream of any seawater addition for control of pH prior to discharge.
The 60-mg/L limit is adjusted upward for lower washwater flow rates per
MWh, and vice-versa, and the applicable permit limits are contained in
table 2 to paragraph (b)(4)(i) of this section.
