A. Does this action apply to me?
Table 1 of this preamble lists the NESHAP and associated regulated
industrial source categories that are the subject of this final rule.
Table 1 is not intended to be exhaustive, but rather provides a guide
for readers regarding the entities that this final rule is likely to
affect. These final standards, once promulgated, will be directly
applicable to the affected sources. Federal, state, local, and tribal
government entities would not be affected by this final rule. As
defined in the Initial List of Categories of Sources Under Section
112(c)(1) of the Clean Air Act Amendments of 1990 (see 57 FR 31576;
July 16, 1992) and Documentation for Developing the Initial Source
Category List, Final Report (see EPA-450/3-91-030; July 1992), the
Manufacture of Paints, Coatings, and Adhesives source category ``is any
facility engaged in their manufacture without regard to the
[[Page 10843]]
particular end-uses or consumers of such products. The manufacturing of
these products may occur in any combination at any facility.'' This
source category has since been renamed Miscellaneous Coating
Manufacturing (MCM).

II. Background
A. What is the statutory authority for this action?
This final rule amends the National Emission Standards for
Hazardous Air Pollutants (NESHAP): Miscellaneous Coating Manufacturing,
which was previously amended when the EPA finalized the Residual Risk
and Technology Review (RTR) on August 14, 2020.\1\
---------------------------------------------------------------------------
\1\ 85 FR 49724; Aug. 14, 2020.
---------------------------------------------------------------------------
In the Louisiana Environmental Action Network v. EPA (LEAN)
decision issued on April 21, 2020, the U.S. Court of Appeals for the
District of Columbia Circuit (D.C. Circuit) held that the EPA has an
obligation to address unregulated emissions from a source category when
the Agency conducts the 8-year technology review required by Clean Air
Act (CAA) section 112(d)(6).\2\ To meet this obligation, the EPA issued
a proposed rule to address unregulated emissions of HAP from the MCM
source category. Inorganic HAP can be emitted from sources in the MCM
category as part of a source's particulate matter (PM) emissions. These
emissions can occur when raw materials in powder form are added to
paint mixing vessels. Therefore, amendments were proposed to define the
maximum achievable control technology (MACT) standard for inorganic HAP
within the MCM source category pursuant to CAA sections 112(d)(2) and
(3).

regulate its organic and inorganic HAP emissions?

---------------------------------------------------------------------------
The MCM source category includes the collection of equipment that
is used to manufacture coatings at a facility. MCM operations also
include cleaning operations. Coatings are materials such as paints,
inks, or adhesives that are intended to be applied to a substrate and
consist of a mixture of resins, pigments, solvents, and/or other
additives, where the material is produced by a manufacturing operation
where materials are blended, mixed, diluted, or otherwise formulated.
Coatings do not include materials made in processes where a formulation
component is synthesized by a chemical reaction or separation activity
and then transferred to another vessel where it is formulated to
produce a material used as a coating, where the synthesized or
separated component is not stored prior to formulation.
The equipment regulated by the MCM NESHAP includes process vessels,
storage tanks for feedstocks and products, equipment leak components
(pumps, compressors, agitators, pressure relief devices (PRDs),
sampling connection systems, open-ended valves or lines, valves,
connectors, and instrumentation systems), wastewater tanks, heat
exchangers, and transfer racks.
The current NESHAP regulates process vessels based on the volume of
the process vessel and the maximum true vapor pressure of the organic
HAP processed or stored. Control requirements range from the use of
tightly fitted lids on process vessels to the capture and reduction of
organic HAP emissions through the use of add-on controls (i.e., a
flare, oxidizer, or condenser).
The NESHAP did not previously regulate inorganic HAP from process
vessels. During the addition of raw materials in powder form to paint
mixing vessels, emissions of inorganic HAP in the form of PM emissions
may occur and are typically collected and routed to a PM control device
(i.e., baghouse, fabric filters, cartridge filters, or scrubbers). This
final rule addresses the previously unaddressed inorganic HAP emissions
from this category and requires MACT for emission sources of inorganic
HAP.
C. What changes did we propose for the MCM source category in our June
7, 2022, proposal?
On June 7, 2022, the EPA published a proposal in the Federal
Register for the MCM NESHAP, 40 CFR part 63, subpart HHHHH, to set a
MACT standard for inorganic HAP metal emissions from process vessels in
the MCM source category. We also proposed to add 1-bromopropane (1-BP)
to table 7, Partially Soluble HAP, and table 11, List of Hazardous Air
Pollutants That Must Be Counted Toward Total Organic HAP Content If
Present at 0.1 Percent or More by Mass, to this subpart. We asked for
comment on these changes, and additionally sought comment on the use of
1-BP in this source category.
III. What is the rationale for our final decisions and amendments for
the NESHAP for the MCM source category?
This section provides a description of what we proposed and what we
are finalizing for the issue, the EPA's rationale for the final
decisions and amendments, and a summary of key comments and responses.
[[Page 10844]]
A. Inorganic HAP Standards for Process Vessels
1. What comments did we receive on the inorganic HAP standards, and
what are our responses?
Comment: We received comments that the EPA should include design
evaluations of PM control devices (i.e., baghouses, fabric filters,
cartridge filters, or scrubbers) as alternatives to EPA Method 5
testing for initial compliance demonstrations. The commenters argued
that coatings production often occurs infrequently, taking a fraction
of the time needed to conduct an EPA Method 5 test. The commenters
argued that EPA Method 5 test runs usually require an hour or more,
whereas the addition of dry solids to an MCM subject process vessel
usually takes no more than 10 or 15 minutes for each batch. The
commenters stated that it could be a matter of days, or months, before
another batch of dry solids is added to a process vessel. Further,
commenters argued that typically only 1 or 2 batches in a year would be
subject to these standards for several reasons, including that the
amendments only apply to process vessels that are greater than or equal
to 250 gallons, and that some of the manufactured materials might not
be coatings. The commenters also stated that besides metal HAP,
facilities might already route any PM to a control device resulting
from the addition of dry solids (i.e., for worker hygiene protection).
Response: Periodic performance tests verify control device
performance and also help identify potential degradation of an add-on
control device over time to ensure the control device remains
effective, reducing the potential for acute emissions episodes or
noncompliance. Therefore, we are finalizing the requirement to conduct
performance testing. The commenters indicate that the most significant
issue is related to the amount of time that the controls are operating
to limit PM emissions. We recognize that there may be instances where
inorganic HAP materials are processed for very limited periods of time
and, therefore, are clarifying that the performance test may be
conducted during any solids addition or processing steps, and not just
during the addition of inorganic HAP-containing materials. We note that
the PM emissions limit proposed for inorganic HAP was based on
performance testing for similar units that had the potential for PM
emissions, and not limited to periods where inorganic HAP-containing
materials were added or processed. We are, therefore, clarifying the
regulatory text at 40 CFR 63.8005(i)(1)(i) to specify that EPA Method 5
may be conducted during the addition of any dry materials.
Comment: Commenters argued that design evaluations are allowed in
other NESHAP rules including 40 CFR part 63, subpart BBBBBBB, Chemical
Preparations Industry; 40 CFR part 63, subpart VVVVVV, Chemical
Manufacturing Area Sources; and 40 CFR part 63, subpart CCCCCCC, Paints
and Allied Products Manufacturing, and therefore should be allowed in
this standard. In addition, commenters argued that the current MCM rule
references 40 CFR part 63, subpart SS, which they claimed allows design
evaluations to control organic HAP.
Response: As discussed above, performance testing is important to
verify initial and periodic control device performance. Although design
evaluations have been allowed in some NESHAP such as the area source
standards identified by the commenter, performance testing is required
in a number of MACT standards to demonstrate compliance. In the August
14, 2020, final rule, we finalized requirements for facilities subject
to subpart HHHHH to conduct control device performance testing no less
frequently than once every 5 years when using emission capture systems
and add-on controls to demonstrate compliance, see 85 FR 49724, 49729,
and removed provisions in conflict with this change. However, we
erroneously did not make a conforming change to 40 CFR 63.8005(d)(1) at
that time to remove now obsolete language addressing the conduct of
design evaluations. We are therefore making a correction to 40 CFR
63.8005(d)(1) to remove the remaining reference regarding design
evaluations in this provision.
Comment: Commenters suggested that the EPA should clarify that 40
CFR part 63, subpart SS, does not apply to PM control devices by adding
clarifying language to 40 CFR 63.8000(a)(2) and (c).
Response: Because the final inorganic HAP metal general
requirements are specified in a separate section from the organic HAP
requirements cited by this commenter, this commenter's suggested
clarifications are unnecessary. The requirements in Sec. 63.8000(a)(2)
and (c) are not related to the metal HAP requirements for PM control
devices. Therefore, we have not made the requested clarifications.
Comment: Commenters suggested that the EPA provide 3 years, rather
than 1 year, to comply with the final rule amendments. Commenters
argued that the EPA did not account for all facilities that will need
to install new control devices for PM. Commenters stated that some
facilities have process vessels that are already controlled with a PM
control device, but have other process vessels at their facilities that
are not currently controlled with a PM control device and would,
therefore, need to install a new PM control device.
Response: The final rule provides 1 year to comply with the
amendments. For most facilities, 1 year to conduct performance tests on
existing inorganic HAP control devices is an adequate amount of time.
The commenters were not specific in terms of how many facilities would
have to install new control devices to meet this final rule, but we
expect that number to be minimal to none. Therefore, we have not
provided additional time. We note, however, that 40 CFR 63.6(i)(4)(ii)
provides an opportunity to request an additional 2 years to comply if
necessary for the installation of controls.
Comment: One commenter suggested that the EPA conduct further
research on the toxicity of non-mercury metal HAP.
Response: This comment is outside of the scope of this rulemaking.
Nonetheless, the EPA continues to research and collect information on
pollutants such as non-mercury metal HAP.
Comment: One commenter suggested that the EPA clarify whether
inorganic HAP metal includes compounds of metal HAP (i.e., manganese,
antimony, nickel, lead, cobalt, chromium, cadmium, or arsenic) or just
these metals themselves. The commenter also suggested that the EPA
clarify whether the metal HAP limit of 0.1 percent by weight refers to
the content of one single metal HAP compound or the total content of
the metal HAP compounds combined.
Response: The definition of material containing metal HAP includes
compounds of the metals listed and the metals themselves. The 0.1
percent by weight refers to the total content of all the metal HAP
compounds combined and the metals themselves, except for elemental
lead.
Comment: One commenter stated that there is a lack of standards for
pigments and other solids that are in paste or slurry form. The
commenter also suggested that the word ``liquid'' can be removed from
the phrase ``pigments and other solids that are in paste, slurry, or
liquid form,'' as no PM emissions occur in liquids.
Response: We disagree that there need to be standards for pigments
and other solids that are in paste or slurry form as PM emissions do
not occur from processing liquids, pastes, or slurries.
[[Page 10845]]
2. What did we propose and what changes are being made to the inorganic
HAP amendments in this final rule?
This final rule addresses the previously unregulated inorganic HAP
metal emissions from this source category by setting MACT standards for
emission sources of metal HAP by amending the compliance requirements
in 40 CFR 63.7995(f); the general requirements specified in 40 CFR
63.8005(a)(1)(iii) and (i); the reporting requirements specified in 40
CFR 63.8075; the recordkeeping requirements in 40 CFR 63.8080(i) and
(g); and the general provisions as specified in table 10 to this
subpart, as proposed, to set PM standards stating that existing sources
must demonstrate initial compliance with the PM emissions limit of
0.014 grains per dry standard cubic foot (gr/dscf) and new sources must
demonstrate initial compliance with the PM emissions limit of 0.0079
gr/dscf. We are revising table 1 of 40 CFR part 63, subpart HHHHH, as
proposed, to include the 0.014 gr/dscf emission limit that applies to
process vessels. Facilities are required to continuously comply with
the standards during all operations that emit metal HAP. These final
amendments do not apply to pigments and other solids that are in paste,
slurry, or liquid form.
We are finalizing, as proposed, the definitions in 40 CFR 63.8105
for Bag Leak Detection System (BLDS), fabric filter, and material
containing metal HAP. We are also amending the regulatory text at 40
CFR 63.8005(i)(1)(i) to specify that EPA Method 5 may be conducted
during the addition of any dry materials, not only when dry material
containing metal HAP are added.
As finalized, continuous compliance with the emission limits will
be demonstrated through control device parameter monitoring coupled
with periodic emissions testing.
Under this final rule, a source owner is required to submit semi-
annual compliance summary reports which document both compliance with
the requirements of this rule and any deviations from compliance with
any of those requirements.
B. Adding 1-BP to the List of HAP
1. What comments did we receive regarding the addition of 1-BP to our
list of HAP, and what are our responses?
Comment: One commenter argued that the CAA requires the EPA to
establish MACT standards for each uncontrolled HAP, including 1-BP. The
commenter argued that the LEAN decision specifies that the EPA must set
emissions standards for each HAP emitted by the source category. The
commenter stated that the LEAN decision requires the Agency to set MACT
standards for HAP that have not previously been regulated. The
commenter further stated that the EPA did not calculate MACT standards
or establish emissions limits for 1-BP. The commenter stated that the
EPA has never previously calculated how much 1-BP the best performing
sources emit and has not set emissions standards for 1-BP. The
commenter stated that adding 1-BP to table 7, Partially Soluble HAP,
and table 11, List of Hazardous Air Pollutants That Must Be Counted
Toward Total Organic HAP Content If Present at 0.1 Percent or More by
Mass, to this subpart does not satisfy the EPA's obligation to set MACT
standards. The commenter argued that the EPA does not have enough
information to set a MACT floor for 1-BP. The commenter also argued
that a similar analysis should have been completed for 1-BP as it was
done for PM. The commenter argued that the EPA did not conduct a
surrogate analysis between 1-BP and other organic HAP.
Response: As explained in our 2022 proposal, the D.C. Circuit in
LEAN held that EPA has an obligation to address unregulated emissions
from a source category when conducting the 8-year technology review
required by section 112(d)(6). At the time this rule was proposed, we
considered it possible that sources in this source category may use 1-
BP; however, we had no data to support a conclusion that there are
emissions of 1-BP from this source category. Nonetheless, we proposed
to address potential MACT requirements, and stated ``for this source
category, we do not believe that the inclusion of 1-BP as an organic
HAP would have affected the representativeness of the MACT standard.''
We asked for comments and data regarding emissions of 1-BP. However, no
one provided data or other evidence demonstrating that 1-BP is emitted
from this source category. In addition to requesting comments, we
surveyed several MCM facilities to verify our position that 1-BP is not
used in this industry. No respondents to our survey use or emit 1-BP
(see Miscellaneous Coating Manufacturing Source Category (MCM)
Bromopropane (1-BP) Postcard Phone Survey Memo in the docket for this
action).
In response to this comment, we have examined whether the addition
of 1-BP to the HAP list impacts the source category. We proposed to
include 1-BP in the tables that list the regulated HAP for this source
category as a conservative, protective approach. However, our survey
and our knowledge regarding likely sources of 1-BP emissions lead us to
conclude that 1-BP is not used in this source category. Therefore, the
obligation to address unregulated emissions set out in LEAN does not
apply here, and we are not including 1-BP in the list of HAP regulated
in this final rule. The EPA will continue to evaluate the best approach
to address any new HAP additions for each source category as the
applicable NESHAP is reviewed.
2. What did we propose and what changes are being made regarding the
addition of 1-BP in this final rule?
On January 5, 2022, the EPA published in the Federal Register (87
FR 393) a final rule amending the list of HAP under the CAA to add 1-BP
in response to public petitions previously granted by the EPA. This
action became effective on February 4, 2022.
As discussed above, although we proposed to include 1-BP in the
tables that list the regulated HAP for this source category, we
determined that including 1-BP in the tables in this subpart is not the
correct approach for this source category. Based on our brief phone
survey and knowledge of the industry, we have determined that
facilities are not using or emitting 1-BP in this source category.
Therefore, we are not finalizing the addition of 1-BP to table 7,
Partially Soluble HAP, and table 11, List of Hazardous Air Pollutants
That Must Be Counted Toward Total Organic HAP Content If Present at 0.1
Percent or More by Mass, to this subpart to include 1-BP.
C. What are the effective and compliance dates of the standards?
The revisions to the MACT standards being promulgated in this
action are effective on February 22, 2024.
All the provisions we are finalizing under CAA sections 112(d)(2)
and (3) are subject to the compliance deadlines outlined under CAA
section 112(i). For existing sources, CAA section 112(i)(3) provides
there shall be compliance ``as expeditiously as practicable, but in no
event later than 3 years after the effective date of such standard . .
.'' subject to certain exemptions further detailed in the statute.\5\
In determining what compliance period is as ``expeditious as
practicable,'' we examined the amount of time needed to plan and
construct projects and change
[[Page 10846]]
operating procedures. As provided in CAA section 112(i), all new
affected sources would comply with these provisions by the effective
date of the final amendments to the MCM NESHAP or upon startup,
whichever is later.
---------------------------------------------------------------------------
\5\ Association of Battery Recyclers v. EPA, 716 F.3d 667, 672
(D.C. Cir. 2013) (``Section 112(i)(3)'s 3-year maximum compliance
period applies generally to any emission standard . . . promulgated
under [section 112]'' (brackets in original)).
---------------------------------------------------------------------------
All affected facilities would have to continue to meet the current
provisions of 40 CFR part 63, subpart HHHHH, until the applicable
compliance date of the amended rule. This final action is not a ``major
rule'' as defined by 5 U.S.C. 804(2), so the effective date of the
final rule will be the promulgation date as specified in CAA section
112(d)(10).
For all affected sources that commence construction or
reconstruction on or before June 7, 2022, we are finalizing, as
proposed, that it is necessary to provide 1 year after the effective
date of the final rule or upon startup, whichever is later, for owners
and operators to comply with the PM provisions. For all affected
sources that commenced construction or reconstruction after June 7,
2022, we are finalizing, as proposed, that owners and operators comply
with the amended PM provisions by the effective date of the final rule
or upon startup, whichever is later.
IV. Summary of Cost, Enviornmental, and Economic Impacts and Additional
Analyses Conducted
A. What are the affected sources?
Currently, 42 major sources subject to the MCM NESHAP are operating
in the United States. The affected source under the NESHAP is the
facility-wide collection of equipment used to manufacture coatings and
includes all process vessels; storage tanks for feedstocks and
products; components such as pumps, compressors, agitators, PRDs,
sampling connection systems, open-ended valves or lines, valves,
connectors, and instrumentation systems; wastewater tanks; transfer
racks; and cleaning operations. A coating is defined as a material such
as paint, ink, or adhesive that is intended to be applied to a
substrate and consists of a mixture of resins, pigments, solvents, and/
or other additives, where the material is produced by a manufacturing
operation and materials are blended, mixed, diluted, or otherwise
formulated.
B. What are the air quality impacts?
We project no emissions reductions of PM from the MCM source
category because all facilities reporting PM emissions are already
equipped with particulate controls. This action finalizes first-time
standards for inorganic HAP that will limit emissions and require that
controls are effective.
Indirect or secondary air emissions impacts are impacts that would
result from the increased electricity usage associated with the
operation of control devices (e.g., increased secondary emissions of
criteria pollutants from power plants). Energy impacts consist of the
electricity and steam needed to operate control devices and other
equipment. The final amendments would have no effect on the energy
needs of the affected facilities and would, therefore, have no indirect
or secondary air emissions impacts.
C. What are the cost impacts?
All existing MCM facilities are expected to be currently achieving
the level of control required by these final standards. That is, we
believe that all existing sources currently route vent streams from
specified equipment through a PM control device such that PM emissions
are reduced to at least 0.014 gr/dscf. Although this final rule
contains requirements for new sources, we are not aware of any new
sources being constructed now or planned in the next year and,
consequently, we did not estimate any cost impacts for new sources.
Therefore, there are no capital costs of this final rule. The estimated
annualized cost of the final rule would be $205,000 per year. The
annualized costs account for submitting the notifications and for
control device performance testing, inspections, monitoring,
recordkeeping, and reporting for 12 facilities that are expected to
have add-on controls. As stated in the technical support document,
Update of Summary of Data Collected for the MCM RTR Amendments, there
are 12 facilities that reported metal HAP to the 2017 NEI. Therefore,
we expect only 12 facilities to incur costs. This document is available
in the docket for this action. No other capital costs are associated
with this final rule, and no additional operational and maintenance
costs are expected.
D. What are the economic impacts?
For the final rule, the EPA estimated the cost of performing an
initial performance test and annual control device inspections at
affected facilities. To assess the potential economic impacts, the
expected annual cost is compared to the total sales revenue for the
ultimate owners of affected facilities. For this rule, the expected
annual cost is $6,700 for each facility, with an estimated nationwide
annual cost of $205,000 (2019$). The 42 affected facilities are owned
by 27 parent companies, and the total costs associated with these
amendments are expected to be less than 1 percent of annual sales
revenue per ultimate owner. These costs account for 12 facilities
expected to have add-on controls for metal HAP, as well as all 42
facilities to become familiar with the rule. These costs are not
expected to result in a significant market impact, regardless of
whether they are passed on to the purchaser or absorbed by the firms.
The EPA also prepared a small business screening assessment to
determine whether any of the identified affected entities are small
entities, as defined by the U.S. Small Business Administration. This
analysis is available in the docket for this action (Docket ID No. EPA-
HQ-OAR-2018-0747). Three of the affected facilities are owned by small
entities. However, since the costs associated with these amendments for
these 3 affected small entities are expected to be less than 1 percent
of annual sales revenue per ultimate owner, there are no significant
economic impacts on a substantial number of small entities from these
final amendments.
Information on our cost impact estimates on the sources in the MCM
source category is available in the docket for this final rule.
E. What analysis of environmental justice did we conduct?
Consistent with the EPA's commitment to integrating environmental
justice (EJ) in the Agency's actions, and following the directives set
forth in multiple Executive orders, the Agency has carefully determined
the impacts of this action on communities with EJ concerns. For MCM
facilities, the demographic proximity analysis shows the population for
people of color is similar to or lower than the national average.
However, the subcategory of the African American population is above
the national average, as well as low-income and the population without
a high-school diploma. This action will set emission standards for
inorganic HAP metals. However, all existing sources currently operate
control technologies and devices such that no further emission
reductions are anticipated as a result of this action, including in
communities already overburdened by pollution, which are often minority
(i.e., people of color and/or indigenous peoples) and low-income.
Following is a more detailed description of how the Agency considers EJ
in the context of regulatory
[[Page 10847]]
development, and specific actions taken to address EJ concerns for this
action.
Executive Order 12898 directs the EPA to identify the populations
of concern who are most likely to experience unequal burdens from
environmental harms, which are specifically minority populations (i.e.,
people of color and/or indigenous people) and low-income populations
(59 FR 7629; February 16, 1994). Additionally, Executive Order 13985 is
intended to advance racial equity and support underserved communities
through Federal Government actions (86 FR 7009; January 25, 2021). The
EPA defines EJ as ``the fair treatment and meaningful involvement of
all people regardless of race, color, national origin, or income, with
respect to the development, implementation, and enforcement of
environmental laws, regulations, and policies.'' The EPA further
defines fair treatment to mean that ``no group of people should bear a
disproportionate burden of environmental harms and risks, including
those resulting from the negative environmental consequences of
industrial, governmental, and commercial operations or programs and
policies.'' In recognizing that minority and low-income populations
often bear an unequal burden of environmental harms and risks, the EPA
continues to determine ways of protecting them from adverse public
health and environmental effects of air pollution.
To examine the potential for any EJ issues that might be associated
with MCM facilities, we performed a demographic analysis, which is an
assessment of individual demographic groups of the populations living
within 5 kilometers (km) and 50 km of the facilities. The EPA then
compared the data from this analysis to the national average for each
of the demographic groups.
A summary of the proximity demographic assessment performed for the
major source MCM facilities is included as Table 2 of the proposal (see
87 FR 34622). The results of the demographic analysis indicate that,
for populations within 5 km of the 42 major source MCM facilities, the
percent of the population who are people of color (being the total
population minus the white population) is similar to the national
average (41 percent versus 40 percent). However, the percent African
American population is higher than the national percent (20 percent
versus 12 percent nationally). The percent of people living below the
poverty level (19 percent) and those over 25 without a high school
diploma (15 percent) are higher than the national averages (13 percent
and 12 percent, respectively). The results of the analysis of
populations within 50 km of the 42 major source MCM facilities indicate
that, the percent population of people of color (being the total
population minus the white population) is significantly lower than the
national average (28 percent versus 40 percent). The percent of people
living below the poverty level, those over 25 without a high school
diploma, and people living in linguistic isolation are also lower than
the corresponding national averages. The methodology and the results of
the demographic analysis are presented in a technical report, Analysis
of Demographic Factors for Populations Living Near MCM Facilities,
available in this docket for this action (Docket ID No. EPA-HQ-OAR-
2018-0747).
With regard to HAP emissions, this action requires facilities with
process vessels emitting inorganic HAP, which consist of PM emissions
from addition of raw materials in powder form to paint mixing vessels,
to demonstrate compliance with PM emissions of 0.014 gr/dscf for
existing sources and 0.0079 gr/dscf for new sources. Because all
existing sources control these emissions, no further emission
reductions are anticipated as a result of this action, including in
communities already overburdened by pollution, which are often minority
(i.e., people of color and/or indigenous peoples) and low-income.
V. 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 13563 Improving
Regulation and Regulatory Review
This action is not a significant regulatory action and was
therefore not submitted to the Office of Management and Budget (OMB)
for review.
B. Paperwork Reduction Act (PRA)
The information collection activities in this final rule will be
submitted for approval to OMB under the PRA. The ICR document that the
EPA prepared has been assigned EPA ICR number 2115.10. You can find a
copy of the ICR in the MCM Docket (Docket ID No. EPA-HQ-OAR-2018-0747),
and it is briefly summarized here.
Respondents/affected entities: Facilities manufacturing surface
coatings.
Respondent's obligation to respond: Mandatory (40 CFR part 63,
subpart HHHHH).
Estimated number of respondents: In the year after the amendments
are final, approximately 42 respondents per year would be subject to
the NESHAP and no additional respondents are expected to become subject
to the NESHAP during that period.
Frequency of response: The total number of responses in year 1 is
42, in year 2 is 12, and in year 3 is 12.
Total estimated burden: The average annual burden of the final
amendments to the 42 MCM facilities over the first year if the
amendments are finalized is estimated to be 1,593 hours (per year). The
average annual burden to the Agency over the 3 years after the
amendments are final is estimated to be 49 hours (per year). Burden is
defined in 5 CFR 1320.3(b).
Total estimated cost: The average annual cost of the final
amendments to the MCM facilities is $178,000 in labor costs in the
first 3 years after the amendments are final. The average annual
capital and operation and maintenance costs are $28,000. The total
average annual Agency cost of the final amendments over the first 3
years after the amendments are final is estimated to be $2,330.
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 the
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 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. The
small entities subject to the requirements of this action are MCM
facilities owned by small businesses. Three of the affected facilities
are owned by small entities. However, since the costs associated with
the amendments for these three affected small entities are expected to
be less than one percent of annual sales revenue per ultimate owner,
there are no significant economic impacts on a substantial number of
small entities from these amendments. Details of this analysis are
described in section IV.D. above and additional detail is provided
[[Page 10848]]
in the economic impact memorandums associated with this action.
D. 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. The action imposes
no enforceable duty on any state, local, or tribal governments or the
private sector.
E. Executive Order 13132: Federalism
This action does not have federalism implications. 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.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications as specified in
Executive Order 13175. No tribal facilities are known to be engaged in
any of the industries that would be affected by this action (MCM).
Thus, Executive Order 13175 does not apply to this action. This
action's health and risk assessments are contained in sections IV.E of
this preamble.
Consistent with the EPA Policy on Consultation and Coordination
with Indian Tribes, the EPA offered consultation to tribal officials
during the development of this action. However, the Agency did not
receive a request for consultation. The EPA also provided an overview
on a tribal partnership call on June 30, 2022, during the public
comment period to inform the tribes of the content of the proposed
action and to encourage them to submit comments.
G. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR
Part 51
This action involves technical standards. Therefore, the EPA
conducted searches for the MCM NESHAP through the Enhanced National
Standards Systems Network (NSSN) Database managed by the American
National Standards Institute (ANSI). We also reviewed voluntary
consensus standards (VCS) organizations and accessed and searched their
databases for EPA Methods 5 and 29. During the EPA's VCS search, if the
title or abstract (if provided) of the VCS described technical sampling
and analytical procedures that are similar to the EPA's referenced
method, the EPA ordered a copy of the standard and reviewed it as a
potential equivalent method. We reviewed all potential standards to
determine the practicality of the VCS for this rule. This review
requires significant method validation data that meet the requirements
of EPA Method 301 for accepting alternative methods or scientific,
engineering, and policy equivalence to procedures in the EPA referenced
methods. The EPA may reconsider determinations of impracticality when
additional information is available for a particular VCS.
No applicable VCS was identified for EPA Method 5. The search
identified one VCS that was potentially applicable for this rule in
lieu of EPA Method 29. However, after reviewing the available standard,
the EPA determined that the VCS identified for measuring emissions of
pollutants subject to emissions standards in the rule would not be
practical due to lack of equivalency. Additional information for the
VCS search and determination can be found in the memorandum Voluntary
Consensus Standard Results for National Emission Standards for
Hazardous Air Pollutants: Miscellaneous Coatings Manufacturing
Technology Review, which is available in the docket for this action.
H. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629; February 16, 1994) directs
Federal agencies, to the greatest extent practicable and permitted by
law, to make EJ part of their mission by identifying and addressing, as
appropriate, disproportionately high and adverse human health or
environmental effects of their programs, policies, and activities on
minority populations (people of color and/or indigenous peoples) and
low-income populations.
The EPA anticipates that the human health or environmental
conditions that exist prior to this action result in or have the
potential to result in disproportionate effects on African American and
low-income populations. Near MCM facilities, the percentages of
residents who are African American or low income are higher than the
nationwide percentages. However, based on prior analyses of this source
category (85 FR 49727), risks from HAP pollutants have been found to be
at acceptable levels and this rule will continue to maintain acceptable
levels of exposure.
The EPA anticipates that this action will not change this
characterization of impacts and is not likely to result in new
disproportionate and adverse effects on people of color, low-income
populations, and/or indigenous peoples. All existing sources currently
operate control technologies and devices such that no further emission
reductions are anticipated as a result of this action, including in
communities already overburdened by pollution, which are often minority
(i.e., people of color and/or indigenous peoples) and low-income. The
methodology and the results of the demographic analysis are available
in the docket for this action (Docket ID No. EPA-HQ-OAR-2018-0747) in
the technical report Analysis of Demographic Factors for Populations
Living Near MCM Facilities.
I. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045 because it is
not economically significant as defined in Executive Order 12866, and
because this action does not present any changes to the rule that would
affect environmental health or safety risks, including those that would
present a disproportionate risk to children.
J. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.
K. Congressional Review Act (CRA)
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 not a ``major rule'' as defined by 5
U.S.C. 804(2).
