Postponement of Certain Compliance Dates for the Effluent
Limitations Guidelines and Standards for the Steam Electric Power
Generating Point Source Category
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: Under the Clean Water Act (``CWA''), The Environmental
Protection Agency (EPA) intends to conduct a rulemaking to potentially
revise certain best available technology economically achievable
(``BAT'') effluent limitations and pretreatment standards for existing
sources (``PSES'') for the steam electric power generating point source
category, which were published in the Federal Register on November 3,
2015. EPA is, accordingly, postponing the associated compliance dates
in the 2015 Rule. In particular, EPA is postponing the earliest
compliance dates for the new, more stringent, BAT effluent limitations
and PSES for flue gas desulfurization (``FGD'') wastewater and bottom
ash transport water in the 2015 Rule for a period of two years. At this
time, EPA does not intend to conduct a rulemaking that would
potentially revise the new, more stringent BAT effluent limitations and
pretreatment standards in the 2015 Rule for fly ash transport water,
flue gas mercury control wastewater, and gasification wastewater, or
any of the other requirements in the 2015 Rule. As such, EPA is not
changing the compliance dates for the BAT limitations and PSES
established by the 2015 Rule for these wastestreams. EPA's action to
postpone certain compliance dates in the 2015 Rule is intended to
preserve the status quo for FGD wastewater and bottom ash transport
[[Page 43495]]
water until EPA completes its next rulemaking concerning those
wastestreams, and it thus does not otherwise amend the effluent
limitations guidelines and standards for the steam electric power
generating point source category.
DATES: The final rule is effective September 18, 2017. In accordance
with 40 CFR part 23, this regulation shall be considered issued for
purposes of judicial review at 1 p.m. Eastern Standard Time on October
2, 2017. Under section 509(b)(1) of the CWA, judicial review of this
regulation can be had only by filing a petition for review in the U.S.
Court of Appeals within 120 days after the regulation is considered
issued for purposes of judicial review. Under section 509(b)(2), the
requirements in this regulation may not be challenged later in civil or
criminal proceedings brought by EPA to enforce these requirements.

SUPPLEMENTARY INFORMATION:
I. Background
On November 3, 2015, the EPA published a final rule amending 40 CFR
part 423, the effluent limitations guidelines and standards for the
steam electric power generating point source category, under Sections
301, 304, 306, 307, 308, 402, and 501 of the CWA (33 U.S.C. 1311, 1314,
1316, 1317, 1318, 1342, and 1361). The amendments addressed limitations
and standards on various wastestreams at steam electric power plants:
FGD wastewater, bottom ash transport water, fly ash transport water,
flue gas mercury control wastewater, gasification wastewater, and
combustion residual leachate. Collectively, this rulemaking is known as
the ``Effluent Limitations Guidelines and Standards for the Steam
Electric Power Generating Point Source Category,'' or ``2015 Rule.''
For further information on the 2015 Rule, see 80 FR 67838 (November 3,
2015).
EPA received seven petitions for review of the 2015 Rule. The U.S.
Judicial Panel on Multi-District Litigation issued an order on December
8, 2015, consolidating all of the petitions in the U.S. Court of
Appeals for the Fifth Circuit, Southwestern Electric Power Co., et al.
v. EPA, No. 15-60821.
In a letter dated March 24, 2017, the Utility Water Act Group
(``UWAG'') \1\ submitted a petition for reconsideration of the 2015
Rule which requested that EPA suspend the Rule's approaching deadlines.
UWAG supplemented its petition with additional information in a letter
dated April 13, 2017. In a letter dated April 5, 2017, the Small
Business Administration (``SBA'') Office of Advocacy sent EPA a second
petition for reconsideration of the 2015 Rule, which expressly supports
UWAG's petition and raises issues that SBA considers to be pertinent to
small businesses. The petitions raise wide-ranging objections to the
Rule.\2\ Among other things, the UWAG petition points to new data which
they believe show that plants burning subbituminous and bituminous coal
cannot comply with the 2015 Rule's limitations and standards for FGD
wastewater and questions EPA's characterization of bottom ash transport
water. UWAG also requested that EPA suspend or delay the ``rule's fast-
approaching compliance deadlines while EPA works to reconsider and
revise, as appropriate, the substantive requirements of the current
rule.''
---------------------------------------------------------------------------
\1\ According to the petition, UWAG is a voluntary, ad hoc,
unincorporated group of 163 individual energy companies and three
national trade associations of energy companies: Edison Electric
Institute, the National Rural Electric Cooperative Association, and
the American Public Power Association.
\2\ A copy of each petition and the supplemental information is
included in the docket for this rule, Docket ID No. EPA-HQ-OW-2009-
0819.
---------------------------------------------------------------------------
In an April 12, 2017 letter to those who submitted the
reconsideration petitions, the Administrator announced his decision to
reconsider the 2015 Rule. See DCN SE06612. As explained in that letter,
after considering the objections raised in the reconsideration
petitions, the Administrator determined that it is appropriate and in
the public interest to reconsider the Rule. On April 14, 2017, EPA
requested that the Fifth Circuit hold the case in abeyance while the
Agency undertook reconsideration. On April 24, 2017, the Fifth Circuit
granted the motion and placed the case in abeyance.
On June 6, 2017 (82 FR 26017), EPA proposed to postpone the
compliance dates for the new, more stringent, BAT effluent limitations
and PSES in the 2015 Rule for each of the following wastestreams: FGD
wastewater, bottom ash transport water, fly ash transport water, flue
gas mercury control wastewater, and gasification wastewater, while
reconsideration of the 2015 Rule was underway. EPA explained that this
postponement would preserve the regulatory status quo with respect to
wastestreams subject to the 2015 Rule's new, and more stringent,
limitations and standards during reconsideration and that postponement
of compliance dates is intended to prevent the unnecessary expenditure
of resources until EPA finalizes any rulemaking as a result of its
reconsideration of the 2015 Rule. EPA also solicited comments on
whether this postponement should be for a specified period of time, for
example, two years.
On August 11, 2017, EPA sent a second letter to those who had
requested reconsideration of the 2015 Rule, announcing the
Administrator's decision to conduct a new rulemaking to potentially
revise the new, more stringent BAT limitations and PSES in the 2015
Rule that apply to two wastestreams: FGD wastewater and bottom ash
transport water. See DCN SE06670. On August 14, 2017, EPA filed a
motion to govern further proceedings in the U.S. Court of Appeals for
the Fifth Circuit, which explained that EPA intends to conduct further
rulemaking to potentially revise the new, more stringent BAT/PSES
requirements in the 2015 Rule applicable to FGD wastewater and bottom
ash transport water, and requested, in part, that the Court sever and
hold in abeyance all judicial proceedings concerning portions of the
2015 Rule related to those particular requirements. On August 22, 2017,
the Court granted EPA's motion.
In an earlier action, EPA administratively postponed certain
compliance dates that had not yet passed in part of the 2015 Rule
pursuant to Section 705 of the Administrative Procedure Act (``APA''),
5 U.S.C. 705, which states that ``[w]hen an agency finds that justice
so requires, it may postpone the effective date of action taken by it
pending judicial review.'' 82 FR 19005 (April 25, 2017). EPA had
postponed the compliance dates as a
[[Page 43496]]
temporary measure pursuant to Section 705 to preserve the status quo
while the litigation in the Fifth Circuit was pending and EPA's
reconsideration was underway. Because EPA has decided to conduct
further rulemaking to potentially revise the new, more stringent BAT
limitations and PSES in the 2015 Rule applicable to two specific
wastestreams (FGD wastewater and bottom ash transport water), and it is
today finalizing a rule which postpones the associated compliance dates
in the 2015 Rule pending its next rulemaking, there is no longer any
need for the Agency to maintain its prior action pursuant to Section
705 of the APA. EPA, hereby, withdraws that action.
II. Summary of Comments Received
EPA received thousands of written comments on the proposed rule to
postpone certain compliance dates in the 2015 Rule. EPA also held a
public hearing on July 31, 2017. The comments on the proposed rule
generally fall into one of four categories: (1) Support for
postponement of compliance dates; (2) opposition to the postponement of
compliance dates; (3) comments on the substantive requirements of the
2015 Rule (which are outside the scope of this action, which concerns
postponing certain compliance dates only); and (4) comments on the
length of time that EPA should postpone the compliance dates.
Commenters that support the postponement rule generally assert that
the postponement is appropriate to prevent industry from spending
``unnecessary resources'' until EPA completes its reconsideration of
the 2015 Rule. Many commenters who support a postponement in compliance
dates state that, given the substantial costs required to implement
technology required to comply with the 2015 Rule, as well as the time
needed for designing and optimizing treatment systems, certainty in the
discharge requirements is needed and postponement of compliance dates
allows for that. In addition, commenters argue that the Agency has both
the authority and the responsibility to postpone the 2015 Rule until it
completes any rulemaking following its reconsideration process.
Comments on the length of the postponement generally assert that
EPA should postpone the compliance dates for a minimum of two years,
until EPA has taken final action on any rule revisions, or some time
period beyond when EPA has taken final action on any rule revisions.
Commenters that oppose the postponement rule generally assert that
(1) the technology bases underlying the 2015 Rule are widely available
and affordable now, many steam electric plants have already installed
or are in the process of implementing these technologies, and
postponing the compliance dates would hinder technology development;
(2) any postponement allows power plants to continue to discharge
pollutants that are harmful to public health and the environment, and
the forgone public health and environmental benefits during any
postponement outweigh the costs to industry; and (3) EPA lacks
authority to postpone the compliance dates.
III. Rationale for Finalizing a Postponement of Compliance Dates
In light of new information not contained in the record for the
2015 Rule and the inherent discretion the Agency has to reconsider past
policy decisions consistent with the CWA and other applicable law, EPA
intends to conduct a new rulemaking regarding the appropriate
technology bases and associated limits for the BAT/PSES requirements
applicable to FGD wastewater and bottom ash transport water discharged
from steam electric power plants. Given this, and after carefully
considering comments received on the proposed rule, EPA finds it
appropriate to postpone the earliest compliance dates for the new, more
stringent, BAT effluent limitations and PSES applicable to FGD
wastewater and bottom ash transport water in the 2015 Rule until it
completes the new rulemaking. This maintains the 2015 Rule as a whole
at this time, with the only change being to postpone specific
compliance deadlines for two wastestreams. Thus, the earliest
compliance dates for plants to meet the new, more stringent FGD
wastewater and bottom ash wastewater limitations and standards in the
2015 Rule, which were to be determined by the permitting authority as a
date ``as soon as possible beginning November 1, 2018 . . .'', are now
to be determined by the permitting authority as a date ``as soon as
possible beginning November 1, 2020 . . . .'' EPA is not changing the
``no later than'' date of December 31, 2023, because EPA is not aware
that the 2023 date is an immediate driver for expenditures by plants
(petitioners had requested relief from the ``fast-approaching
compliance deadlines'' in the 2015 Rule), and EPA plans to take up the
appropriate compliance period in its next rulemaking. In order to be
absolutely clear about what is being postponed, the final rule includes
more precise regulatory text to implement the rule than was included in
the proposed rule.
Agencies have inherent authority to reconsider past decisions and
to revise, replace or repeal a decision to the extent permitted by law
and supported by a reasoned explanation. FCC v. Fox Television
Stations, Inc., 556 U.S. 502, 515 (2009); Motor Vehicle Mfrs. Ass'n v.
State Farm Mutual Auto. Ins. Co., 463 U.S. 29, 42 (1983). See also
Nat'l Ass'n of Home Builders v. EPA, 682 F.3d 1032, 1038 & 1043 (D.C.
Cir. 2012). Particularly relevant here, the CWA expressly authorizes
EPA to revise effluent limitations and standards. 33 U.S.C. 1311(d),
1314(b), (g)(1), (m)(1)(A), 1317(b)(2). Moreover, in doing so, Section
304(b)(2)(B) of the CWA directs EPA to consider several factors,
including ``other factors as the Administrator deems appropriate,'' and
the Agency is afforded considerable discretion in deciding how much
weight to give each factor. See, e.g., Weyerhaeuser Co. v. Costle, 590
F.2d 1011, 1045 (D.C. Cir. 1978). In this case, where EPA has decided
to undertake a new rulemaking, which may result in substantive changes
to the 2015 Rule, that is an appropriate factor to consider and one
that warrants the postponement of compliance dates for the new, more
stringent BAT and PSES requirements for two wastestreams in the 2015
Rule, until such a rulemaking is complete (i.e., EPA issues any final
rule that substantively revises the 2015 Rule or EPA decides not to
issue such a final rule). This will prevent the potentially needless
expenditure of resources during a rulemaking that may ultimately change
the 2015 Rule in these respects.
As mentioned, some commenters stated that the record for the 2015
Rule demonstrates that the technologies underlying the new, more
stringent requirements for FGD wastewater and bottom ash transport
water are widely available and affordable. Notwithstanding statements
in the 2015 Rule record, certain parties have raised serious concerns
about the availability and affordability of the technology basis for
the FGD wastewater and bottom ash transport water requirements in the
2015 Rule, and the Administrator wishes to take some time to carefully
review these requirements in light of those concerns and ensure any
such requirements are technologically available and economically
achievable within the meaning of the statute. EPA has discretion in
determining technological availability and economic achievability and
is not constrained by the CWA to make the same policy decision as the
former Administration, so long as its decision is reasonable. As
explained above, the Agency may
[[Page 43497]]
reconsider past policy decisions consistent with the Clean Water Act
and other applicable law. The Agency may also reconsider technical
determinations in light of new information submitted to the Agency that
was not in the record for the 2015 Rule. EPA intends to fully evaluate
all of the issues raised in the petitions, including concerns about:
Cost and impacts to steam electric facilities, public availability of
information on which the rule is based, lack of data for plants that
burn certain types of coal, and validity of certain pollutant data used
in EPA's 2015 Rule analysis. For example, petitioners raised concerns
about the numerical BAT limitations and PSES applicable to FGD
wastewater in the 2015 Rule. They assert that there are differences
among coal types that affect the performance and costs of biological
treatment and that EPA did not have data to demonstrate the performance
of biological treatment on all coal types. To resolve this concern,
following the rulemaking, industry collected (and continues to collect)
additional data on the performance of biological treatment for
different coal types. As another example, petitioners raised questions
about the inclusion and validity of certain data due, in part, to what
they assert are flaws in data acceptance criteria, obsolete analytical
methods, and the treatment of non-detect analytical results, which
petitioners believed resulted in an overestimation of pollutant
loadings for bottom ash transport water. EPA agrees that these are
important issues that warrant further consideration in conjunction with
the statutory factors for determining BAT for these wastestreams. EPA
thus intends to re-evaluate these and other concerns raised in the
petitions in the next rulemaking. EPA acknowledges that postponement of
certain of the 2015 Rule's compliance dates may be disruptive to
vendors and treatment technology suppliers. EPA, however, must also
consider the substantial investments required by the steam electric
power industry to comply with the BAT limitations and PSES,\3\ and that
certainty regarding the limitations and standards deserves prominent
consideration by the Agency when these limitations and standards may
change. As UWAG pointed out in its April 13, 2017 letter, ``a rule of
this magnitude and complexity requires substantial time to come into
compliance for multiple wastestreams. Detailed studies and planning,
followed by large capital expenditures and subsequent installation and
testing, are time-consuming.'' Companies have been evaluating their
compliance options and are reaching the point at which they will be
committing funds, incurring costs, or commencing construction to
install technologies.
---------------------------------------------------------------------------
\3\ In the 2015 Rule, EPA estimated the total annualized pre-tax
compliance costs for the FGD and bottom ash requirements to be
$486.8 million. See DCN SE05978.
---------------------------------------------------------------------------
As part of the 2015 Rule, EPA estimated the costs associated with
compliance with the 2015 Rule's new requirements. For all applicable
wastestreams, EPA assessed the operations and treatment system
components, identified equipment and process changes that the plant
would likely make to meet the 2015 Rule, and estimated the cost to
implement those changes. This includes, among other things, the capital
costs of installing the technology (based on estimates of the
technology selected as representing the level of control) and the
operation and maintenance costs of operating the technology. See
Technical Development Document (``TDD''), pp. 9-1 through 9-52. EPA
estimated that the total post-tax annualized compliance costs would be
$339.6 million/year. See Regulatory Impact Analysis (``RIA''), Table 3-
2 (Option D).\4\
---------------------------------------------------------------------------
\4\ EPA analyzed both pre-tax and post-tax costs. Pre-tax costs
provide insight on the total expenditures as initially incurred by
the plants. Post-tax costs are a more meaningful measure of
compliance impact on privately owned for-profit plants, and
incorporate approximate capital depreciation and other relevant tax
treatments in the analysis. RIA, p. 3-6.
---------------------------------------------------------------------------
The 2015 rulemaking record also describes evaluation of the initial
capital costs that regulated parties would incur in the near term (if a
stay were not in place) to meet the 2015 Rule's effluent limitations
and standards. For the purpose of analysis, in the RIA, EPA assumed
that all capital costs are incurred concurrently with technology
installation according to discharge permit renewal schedules, but EPA
realizes that feasibility studies and planning may need to be completed
in advance of that date. Specifically, plants would incur engineering
design costs, costs to acquire equipment, freight shipping costs to
transport equipment from manufacturers to the installation site, costs
for actions to prepare the site (such as installing concrete
foundations and buildings for the new equipment), and construction
expenses associated with connecting electrical and piping systems to
new equipment. See TDD, p. 9-3. EPA estimated post-tax annualized
capital costs of $204.4 million/year. See RIA, Table 3-2 (Option D).
Although there is a wide degree of variability among the costs
particular plants would expend, EPA estimates that the average post-tax
annualized capital compliance costs for a plant would be approximately
$1.5 million/year. See TDD, Table 9-19 (plants with compliance costs);
RIA, Table 3-2 (Option D). To the extent that these costs are
associated with the 2015 Rule requirements for FGD wastewater and
bottom ash transport water, and in the event that EPA revises these
requirements in a future rulemaking, these are costs that would be
incurred for activities that ultimately might not be necessary. In that
case, this would reflect costs incurred by facilities and potentially
passed on to utility rate payers that ultimately did not need to be
spent.
In light of these imminent planning and capital expenditures that
facilities incurring costs under the 2015 Rule would need to undertake
in order to meet the earliest compliance deadlines for the new, more
stringent limitations and standards in the 2015 Rule, and the fact that
the Agency is conducting a new rulemaking regarding the appropriate
technology bases and associated limits for BAT limitations and PSES
applicable to FGD wastewater and bottom ash transport water, the Agency
views it as appropriate to postpone the earliest compliance dates that
have not yet passed for these wastestreams in 2015 Rule. This will
preserve the regulatory status quo with respect to requirements for FGD
wastewater and bottom ash transport water until the new rulemaking is
complete.
Some commenters also express concerns that postponement of
compliance dates would hinder technology advancements. EPA's experience
does not support this concern. The record for the 2015 Rule
demonstrates that technology advancements were not hindered during that
rulemaking. Rather, as explained in the preamble to the final 2015
Rule, vendors continued to improve existing technologies and to develop
new technologies during the rulemaking leading up to the 2015 Rule.
EPA acknowledges that postponement of the compliance dates could
lead to a delay in the accrual of some of the benefits attributable to
the 2015 Rule. The 2015 Rule required that steam electric power plants
would comply with the new, more stringent requirements no later than
2023, with plants expected to implement new control technologies over a
five-year compliance period of 2019-2023 according to their permit
renewal schedule. In the record for the 2015 Rule, EPA estimated the
value of certain benefits linked to reduced pollutant
[[Page 43498]]
discharges that could be monetized for the period 2019 through 2042.
Based on the 2015 Rule data and methodology, and depending on the
inclusion of the Clean Power Plan, EPA estimates that foregone
annualized benefits for a two-year delay would be between $26.6 million
and $33.6 million.\5\ EPA similarly estimates that plants would
experience annualized cost savings of between $27.5 million and $36.8
million as a result of a two-year delay. See DCN SE06668 for additional
details, including calculations of the foregone benefits and cost
savings. EPA understands that these estimates have uncertainty due to,
for example, the possibility of unexpected implementation approaches,
and thus that the actual cost savings could have been somewhat higher
or lower than estimated. Similarly, due to data and analysis
limitations, the forgone monetized benefits are likely underestimated.
These estimates, however, are consistent with and reflect the best data
and analysis available at the time of the 2015 Rule.
---------------------------------------------------------------------------
\5\ The calculations are based on the benefits and costs
estimated for the 2015 Rule, which were detailed in the ``Benefit
and Cost Analysis for the Effluent Limitations Guidelines and
Standards for the Steam Electric Power Generating Point Source
Category'' (BCA) and ``Regulatory Impact Analysis for the Effluent
Limitations Guidelines and Standards for the Steam Electric Power
Generating Point Source Category'' (RIA) reports.
---------------------------------------------------------------------------
EPA notes that, as explained earlier, there is uncertainty as to
the FGD wastewater and bottom ash transport water BAT/PSES requirements
while EPA conducts a new rulemaking. If EPA did not postpone the
compliance dates, industry would likely incur costs as it prepares to
comply with the 2015 Rule, irrespective of what EPA ultimately
determines to be BAT/PSES for FGD wastewater and bottom ash transport
water. By contrast, under the 2015 Rule, even if permits were written
today, the earliest those permits would have required compliance with
the limitations and standards at issue are ``as soon as possible
beginning November 1, 2018.'' So, while some companies would have to
plan to comply and spend money right away, the benefits would not begin
to accrue until 2018, at the earliest. Also, these benefits may not be
lost if a permitting authority requires similar effluent limitations
where necessary to meet applicable water quality standards, under CWA
section 301(b)(1)(C). EPA has carefully weighed the concerns about
potentially foregone benefits with the consideration of the costs that
could needlessly be incurred should the requirements be changed, as
well as the overall uncertainty and potential confusion that would be
caused by imposing the 2015 Rule requirements while simultaneously
undertaking rulemaking that may change those requirements. On balance,
EPA has concluded the more reasonable approach is to postpone the
compliance dates in the 2015 Rule.
Thus, EPA agrees with commenters who argue that it should postpone
the new, more stringent BAT/PSES requirements for FGD wastewater and
bottom ash transport water in the 2015 Rule until it completes a new
rulemaking on these wastestreams. After reflecting on the time it
typically takes the Agency to propose and finalize revised effluent
limitations guidelines and standards, and in light the characteristics
of this industry and the anticipated scope of the next rulemaking, EPA
projects it will take approximately three years to propose and finalize
a new rule (Fall 2020). See DCN SE06667. Consequently, EPA is
postponing the earliest compliance dates for the new, more stringent,
BAT effluent limitations and PSES for FGD wastewater and bottom ash
transport water for a period of two years (November 1, 2020).\6\ To the
extent that commenters believe a postponement under this rule should
last beyond the time it takes EPA to complete its new rulemaking, such
comments are appropriately considered as part of, and in light of, that
new rulemaking and not this action. As explained, this rule is intended
only as a relatively short-term measure until EPA completes the next
rulemaking, and EPA anticipates that the next rulemaking will
necessarily address compliance dates in some fashion. Although EPA
proposed to postpone the compliance dates for the new, more stringent
requirements applicable to fly ash transport water, gasification
wastewater, and flue gas mercury control (FGMC) wastewater, in addition
to the requirements for FGD wastewater and bottom ash transport water,
this final rule does not postpone those former compliance dates.
Commenters stated that EPA has no basis to postpone compliance dates
for requirements that parties have not expressly argued should be
reconsidered, such as those for fly ash transport water and FGMC
wastewater. EPA agrees that the final rule should postpone only those
requirements that the Agency plans to potentially revise in the next
rulemaking. Because EPA is not conducting a new rulemaking concerning
any of the other issues addressed by the 2015 Rule, including
requirements for fly ash transport water, gasification wastewater, and
FGMC wastewater, EPA is not changing the compliance dates for these
wastestreams or any of the other compliance dates for the requirements
in that Rule. The record for the 2015 Rule demonstrates that changes
associated with converting a fly ash system are unrelated from an
engineering perspective to conversions/upgrades for bottom ash
transport water and FGD treatment systems. Converting a fly ash system
requires installing a silo to capture the dry fly ash, which is
subsequently transported offsite to beneficial reuse markets (e.g.,
cement plants) or landfilled. Bottom ash is handled separately,
regardless of whether it is wet or dry. The same is true for FGD
wastes. EPA recognizes however, that from a financing and long-term
planning perspective, there are advantages to a facility in knowing the
full suite of requirements it will need to comply with over a longer
term planning horizon.
---------------------------------------------------------------------------
\6\ If EPA does not complete a new rulemaking by November, 2020,
it plans to further postpone the compliance dates such that the
earliest compliance date is not prior to completion of a new
rulemaking.
---------------------------------------------------------------------------
Some facilities commented that they may need to know what the
ultimate requirements will be for bottom ash transport water and FGD
wastewater to assist them in considering alternatives for meeting the
requirements for the other waste streams (fly ash transport water and
FGMC wastewater) for which EPA is not postponing the earliest
compliance dates. EPA notes that there continues to be discretion under
the 2015 Rule for permitting authorities to consider: Time needed to
``expeditiously plan (including time to raise capital), design,
procure, and install equipment'' to comply with the rule; changes being
made at the plant to comply with several other rules; and ``other
factors as appropriate'' in determining exactly when, within a
specified compliance period, the 2015 Rule's new, more stringent
limitations apply to any given plant. See 40 CFR 423.11(t).
In light of the compliance date postponements being finalized
today, in determining the ``as soon as possible date,'' EPA believes it
would be reasonable for permitting authorities to consider the need for
a facility to make integrated planning decisions regarding compliance
with the requirements for all of the wastestreams currently subject to
new, more stringent requirements in the 2015 Rule, as well as the other
rules identified in Sec. 423.11(t) to the extent that a facility
demonstrates such a need. This could include harmonizing schedules to
the extent provided for
[[Page 43499]]
under the 2015 Rule \7\ for meeting the 2015 Rule requirements for fly
ash transport water and FGMC wastewater to allow time for a facility to
have certainty regarding what their ultimate requirements will be under
the steam electric ELGs, as well as the requirements under the other
rules listed in Sec. 423.11(t).
---------------------------------------------------------------------------
\7\ For any final effluent limitation that is specified to
become applicable after November 1, 2018, the specified date must be
as soon as possible, but in no case later than December 31, 2023.
---------------------------------------------------------------------------
This rule is effective immediately upon publication. Section 553(d)
of the Administrative Procedure Act, 5 U.S.C. 553(d), provides that
publication of a substantive rule must be made no less than 30 days
before its effective date, subject to several exceptions. Section
553(d)(1) establishes an exception for ``a substantive rule which
grants or recognizes an exemption or relieves a restriction.'' The
exception in Section 553(d)(1) reflects the purpose of the 30-day
notice requirement, which is to give affected entities time to prepare
for the effective date of a rule or to take any other action which the
issuance of a rule may prompt. This rule fits within Section 553(d)(1)
because it postpones certain requirements on steam electric power
plants to control their pollutant discharges by two years, and as a
result, it relieves a restriction on regulated entities for that
period.
IV. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review; and,
Executive Order 13563: Improving Regulation and Regulatory Review
This action is a significant regulatory action that was submitted
to the Office of Management and Budget (OMB) for review. Any changes
made in response to OMB recommendations have been documented in the
docket.
B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs
This action is considered an Executive Order 13771 deregulatory
action. Details on the estimated cost savings of this final rule can be
found in EPA's analysis of the potential costs and benefits associated
with this action.
C. Paperwork Reduction Act
This final rule does not involve any information collection
activities subject to the PRA, 44 U.S.C. 3501 et seq.
D. 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. In
making this determination, the impact of concern is any significant
adverse economic impact on small entities. An agency may certify that a
rule will not have a significant economic impact on a substantial
number of small entities if the rule relieves regulatory burden, has no
net burden or otherwise has a positive economic effect on the small
entities subject to the rule. This action maintains the 2015 Rule as a
whole at this time, with the only change being to postpone specific
compliance deadlines for two wastestreams. As described above, EPA
estimates that steam electric plants, including some small entities,
would experience annualized cost savings of $27.5 million as a result
of this two-year delay. We have therefore concluded that this action
will relieve regulatory burden for some directly regulated small
entities.
E. Unfunded Mandates Reform Act (UMRA)
This action does not contain an unfunded mandate of $100 million or
more as described in UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments.
F. Executive Order 13132: Federalism
This action does not have federalism implications, as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999). It will not have
substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have Tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000).
H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
This final rule is not subject to Executive Order 13045 (62 FR
19885, April 23, 1997) because EPA previously determined that the
environmental health risks or safety risks addressed by the
requirements EPA is finalizing do not present a disproportionate risk
to children.
I. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or 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.
J. National Technology Transfer and Advancement Act (NTTAA)
This rulemaking does not involve technical standards that would
require Agency consideration under NTTAA section 12(d), 15 U.S.C. 272
note.
K. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
This is a final rule to delay action, and it does not change the
requirements of the effluent limitations guidelines and standards
published in 2015. While the postponement in compliance dates could
delay the protection the 2015 Rule would afford to all communities,
including those impacted disproportionately by the pollutants in
certain wastewater discharges, this action would not change any impacts
of the 2015 Rule upon implementation. The EPA therefore believes it is
more appropriate to consider the impact on minority and low-income
populations in the context of possible substantive changes as part of
any future rulemaking.
L. Congressional Review Act
This action is subject to the CRA, and the EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is a not a ``major rule'' as defined by
5 U.S.C. 804(2).
