Abstract
The U.S. Environmental Protection Agency (EPA) is approving revisions and additions to Michigan Air Pollution Control Rules (MAPCR) Parts 6 and 8 for inclusion in the Michigan State Implementation Plan (SIP). Michigan submitted these SIP revisions to meet the Moderate Volatile Organic Compound (VOC) and Nitrogen Oxide (NO<INF>X</INF>) Reasonably Available Control Technology (RACT) requirements for the Western Michigan nonattainment areas (Berrien, Western portion of Allegan, and Western portion of Muskegon counties) under the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). The EPA is approving rules that limit VOC emissions from consumer products and architectural and industrial maintenance coatings, as SIP strengthening measures for the Western Michigan nonattainment areas under the 2015 ozone standard. The EPA proposed to approve this action on February 27, 2026, and received eleven sets of comments.

-----------------------------------------------------------------------
SUMMARY: The U.S. Environmental Protection Agency (EPA) is approving
revisions and additions to Michigan Air Pollution Control Rules (MAPCR)
Parts 6 and 8 for inclusion in the Michigan State Implementation Plan
(SIP). Michigan submitted these SIP revisions to meet the Moderate
Volatile Organic Compound (VOC) and Nitrogen Oxide (NO<INF>X</INF>)
Reasonably Available Control Technology (RACT) requirements for the
Western Michigan nonattainment areas (Berrien, Western portion of
Allegan, and Western portion of Muskegon counties) under the 2015 ozone
National Ambient Air Quality Standard (NAAQS or standard). The EPA is
approving rules that limit VOC emissions from consumer products and
architectural and industrial maintenance coatings, as SIP strengthening
measures for the Western Michigan nonattainment areas under the 2015
ozone standard. The EPA proposed to approve this action on February 27,
2026, and received eleven sets of comments.
DATES: This final rule is effective on September 28, 2026.
ADDRESSES: The EPA has established a docket for this action under
Docket ID No. EPA-R05-OAR-2024-0137 (for VOC RACT) or EPA-R05-OAR-2025-

I. What action is the EPA taking?
The EPA is approving various revisions and additions to MAPCR Parts
6 and 8 into the Michigan SIP as described in the Preamble above. The
EPA is approving these revisions as meeting the Moderate VOC and
NO<INF>X</INF> RACT requirements of Clean Air Act (CAA) sections
182(b)(2) and 182(f), respectively, for the Western Michigan
nonattainment areas under the 2015 ozone standard. EPA is also
approving MAPCR Rules 336.1660 and 336.1662, which limit VOC emissions
from consumer products and architectural and industrial maintenance
coatings, as SIP strengthening measures for the areas. SIP revisions to
Rules 336.1801,
[[Page 55275]]
336.1802, 336.1803, 336.1810, 336.1818, 336.1841(8), 336.1842(10), and
336.1844(9) are responsive to different CAA requirements and will be
considered in a separate rulemaking.
II. Background Information
The Michigan Department of Environment, Great Lakes, and Energy
(Michigan or EGLE) submitted the VOC SIP revisions on March 7, 2024,
supplemented on May 2, 2024, and NO<INF>X</INF> SIP revisions on May 5,
2025, supplemented on August 6, 2025. On February 27, 2026 (91 FR
9793), the EPA proposed to approve revisions and additions to MAPCR
Parts 6 and 8 to meet the Moderate VOC and NO<INF>X</INF> RACT
requirements for the Western Michigan nonattainment areas under the
2015 ozone standard. The EPA also proposed to approve rules that limit
VOC emissions from consumer products and architectural and industrial
maintenance coatings, as SIP strengthening measures for the Western
Michigan nonattainment areas under the 2015 ozone standard.
The EPA is incorporating by reference Michigan rules R 336.1601,
except for R 336.1601(a); R 336.1602; R 336.1606; R 336.1607; R

336.1844, except for R 336.1844(9); R 336.1845; and R 336.1846;
effective April 28, 2025.
An explanation of the CAA requirements, a detailed analysis of the
revisions, and the EPA's reasons for proposing approval were provided
in the notice of proposed rulemaking and will not be restated here. The
EPA provided a 30-day review and comment period for this action in the
proposal. The comment period ended on March 30, 2026. The EPA reopened
the 30-day comment period on April 23, 2026, and this extension ended
on May 26, 2026. The EPA received eleven comments in total--one
supportive, six not relevant, and four adverse.
The six comments that are not relevant to this action covered a
variety of topics including: a general statement regarding the ozone
layer, information on a VOC control technology intended to reduce VOC
emissions from open containers. All of the comments received are
included in the docket for this action. We do not consider these six
comments to be germane or relevant to this action and therefore not
adverse to this action. These comments lack the required specificity to
the proposed SIP revision and the relevant requirements of CAA section
110. Moreover, none of these comments address a specific regulation or
provision in question or recommend a different action on the SIP
submission from what the EPA proposed.
III. Public Comments
Comment: The commenter asserts that the EPA requires States to
adopt the ``best available controls'' when determining RACT and cites
more stringent requirements in other States for the following
categories:
<bullet> VOC RACT:
[cir] Surface coating of cans, coils, paper, fabrics, automobiles,
and light-duty trucks (San Joaquin Valley, CA)
[cir] Existing Aerospace Manufacturing and Rework Operations
(Oregon, Pennsylvania)
[cir] Existing Metals Parts, Metal Products, and Motor Vehicle
Surfacing Coating Lines (Delaware)
<bullet> NO<INF>X</INF> RACT:
[cir] Boilers (San Joaquin Valley, CA)
[cir] Combustion turbines (San Joaquin Valley, CA and Connecticut)
[cir] Internal combustion engines (South Coast AQMD, CA)
Response: The EPA disagrees with the commenter's interpretation of
RACT. The EPA has long defined RACT as the lowest emission limitation
that a particular source is capable of meeting through application of
control technology that is reasonably available, considering
technological and economic feasibility (44 FR 53762, September 17,
1979).
RACT is distinct from Best Available Control Technology (BACT),
which applies under the New Source Review (NSR) program (see CAA
section 169(3) and 40 CFR 51.166). RACT applies to existing sources and
reflects a different statutory standard.
The existence of more stringent emission limits in other States
does not establish that such limits are reasonably available in
Michigan. The examples cited by the commenter are from areas classified
as Serious or Extreme nonattainment; these areas may choose to go
beyond RACT for attainment planning purposes. The Michigan rules in
this action are to address Moderate requirements in the West Michigan
nonattainment areas, for which RACT is the applicable control level
under CAA section 182(b)(2).
Therefore, EPA finds that differences in emission limits across
other States are expected and consistent with the CAA.
Comment: That commenter argues Michigan must justify any deviation
from the most stringent controls and has failed to demonstrate
technological or economic infeasibility.
Response: The EPA disagrees with the commenter's interpretation of
the RACT requirement. The CAA does not require States to adopt the most
stringent controls implemented anywhere in the country. Rather, States
must demonstrate that their selected controls meet the RACT standard,
which is based on reasonable technological and economic feasibility.
Michigan conducted a due diligence review consistent with the EPA's
guidance, including evaluation of Control Technique Guidelines (CTGs),
existing SIP-approved rules, and controls implemented in other States.
Differences in requirements reflect variation in source characteristics
and feasibility considerations.
The EPA finds that Michigan has provided an adequate basis for its
RACT determinations.
Comment: That commenter asserts that Michigan failed to provide
sufficient justification for higher exemption thresholds, did not
include sufficient detail--such as facility-specific data--in its five
percent equivalency analysis to enable meaningful public input or the
EPA review, and relied on assumptions that the commenter asserts affect
the analysis.
Response: The EPA finds that Michigan's submittal satisfies
applicable CAA requirements and adequately addresses the issues raised
by the commenter.
First, Michigan has adopted the more stringent exemption threshold
of 15 pounds per day (2.7 tons per year) for the Western Michigan
nonattainment areas under the 2015 ozone standard through rules R
336.1610a, R 336.1620a, R 336.1621a, and R 336.1624a. These rules
implement VOC RACT for the relevant source categories. Therefore,
Michigan has met Moderate VOC RACT requirements for these categories in
those areas.
Second, the exemption threshold SIP revisions commenter references
apply to areas outside of the Western Michigan nonattainment areas
under the 2015 ozone standard where RACT and a five
[[Page 55276]]
percent equivalency analysis are not required. Although Michigan
submitted a five percent equivalency analysis, the EPA is evaluating
and approving these revisions under CAA section 110(l). The EPA is not
approving rules R 336.1610, R 336.1620, R 336.1621, and R 336.1624 as
RACT.
Under CAA section 110(l), the relevant inquiry is whether the SIP
revision will interfere with attainment, reasonable further progress
(RFP), or any other applicable requirement. Michigan's analysis
demonstrates that the revised exemption thresholds will not result in
an increase in VOC emissions that would interfere with these
requirements.
Because the EPA's approval is based on CAA section 110(l), the
commenter's concerns regarding the level of detail in the five percent
equivalency analysis, including the absence of facility-specific data
and assumptions used in that analysis, do not affect the approvability
of the revision. The EPA finds that the record contains sufficient
information to conclude that the revisions will not interfere with
applicable CAA requirements.
The EPA therefore concludes that Michigan's analysis provides an
adequate basis for approval.
Comment: That commenter states that the EPA should clarify that the
approval of EGLE's proposed SIP submission to apply only to the West
Michigan nonattainment areas as the title of the proposed rule is
highly misleading if it is intended apply to the whole State.
Response: The EPA acknowledges the commenter's concerns; however,
this proposed and final action only approves this SIP submission as
meeting the RACT requirement for the West Michigan areas. Michigan
would have to make a new submission to meet RACT requirements for other
nonattainment areas in the State.
Comment: Two commenters allege that the technical support
documentation (TSD) was not adequately available during the public
comment period.
Response: The EPA acknowledges these commenters' concern regarding
availability of technical support documentation. In response, the EPA
extended the public comment period to ensure that the TSD was available
for a full 30-day review period.
The EPA finds that providing the TSD for a full 30-day public
comment period afforded adequate opportunity for meaningful public
participation consistent with the CAA and Administrative Procedure Act.
Therefore, the EPA concludes that the extended comment period addressed
both commenters' concerns and provided sufficient opportunity for
review and comment.
Comment: The commenter asserts that the EPA's proposal fails to
document CAA 110(a) SIP approval criteria under 42 U.S.C. 7410(a)(2).
Response: CAA 110(a) contains infrastructure SIP (iSIP)
requirements, and the EPA has taken action on infrastructure
requirements and approved iSIP elements for Michigan in separate
actions; therefore, it is not relevant to address in this action.
Comment: That commenter states that the EPA's proposal fails to
document source-specific RACT determinations, comparison to EPA CTGs,
or evaluation against current best available control measures (BACM).
Response: The EPA finds that Michigan's submittal satisfies
applicable CAA requirements for RACT and adequately addresses the
issues raised by the commenter. Michigan provided source-specific RACT
analyses and conducted a due diligence review consistent with the EPA's
guidance, including evaluation of CTGs, existing SIP-approved rules,
and controls implemented in other States. RACT is distinct from BACM,
which applies under CAA 189(b)(1)(B) and does not apply to ozone
nonattainment areas. RACT applies to existing sources and reflects a
different statutory standard. Therefore, The EPA finds that Michigan
has provided an adequate basis for its RACT determinations.
Comment: That commenter claims the EPA's proposal fails to document
RFP demonstrations to comply with CAA 172(c)(2)
Response: The EPA has taken action on and approved RFP requirements
in a separate action (91 FR 9453, February 26, 2026).
Comment: That commenter claims the EPA's proposal fails to document
an anti-backsliding analysis to comply with CAA 193.
Response: The EPA finds that Michigan's submittal does not trigger
a need for an anti-backsliding analysis under CAA 193 as no control
requirements are being removed but rather added or strengthened.
Comment: That commenter insists the EPA's proposal fails to
document a National Environmental Policy Act (NEPA) significance
determination or a basis for any claimed exemption.
Response: The EPA determined that this action is not a ``major
federal action'' that significantly affects the quality of the human
environment as it is approving State choices as meeting the CAA and
does not impose any additional requirements beyond those required by
State law.
Comment: That commenter alleges that the EPA's proposal does not
document an environmental justice analysis under Executive Order (E.O.)
12898 and E.O. 14008.
Response: An environmental justice analysis is not required as both
E.O. 12898 and E.O. 14008 were rescinded.
Comment: That commenter claims the EPA's proposal fails to document
a children's health analysis for ozone under E.O. 13045 and fails to
provide a reasoned explanation under State Farm, Encino, West Virginia
v. EPA, and Loper Bright.
Response: This action is not subject to E.O. 13045 and these court
decisions because it merely approves State choices as meeting the CAA
and does not impose any additional requirements beyond those required
by State law.
Comment: That commenter states that the EPA's proposal fails to
document Tribal consultation under E.O. 13175.
Response: This action is not approved to apply on any Indian
reservation land or in any other area where the EPA or an Indian Tribe
has demonstrated that a Tribe has jurisdiction. In those areas of
Indian country, the rule does not have Tribal implications and will not
impose substantial direct costs on Tribal governments or preempt Tribal
law.
Comment: That commenter insists the EPA's proposal fails to
document an E.O. 13132 federalism analysis.
Response: This action does not have federalism implications as
specified in E.O. 13132.
Comment: That commenter asserts that the EPA should develop an
Initial Regulatory Flexibility Analysis (RFA) or revised certification
with supporting evidence to demonstrate a lack of significant economic
impact on a substantial number of small entities.
Response: An RFA is inapplicable to this rulemaking because the
regulatory analysis provisions of the RFA are only triggered by a
threshold determination by the Agency that this rule will have a
significant economic impact on a substantial number of small entities.
Because the Agency has certified this rule will not have a significant
economic impact, section 603 and 604 of the RFA do not apply to this
rulemaking. 5 U.S.C. 605(b).
Comment: That commenter states that the proposal does not provide
an Unfunded Mandates Reform Act (UMRA) analysis as to whether this
action imposes a Federal intergovernmental mandate.
Response: The EPA has already complied with any UMRA obligation by
including in the proposed rulemaking
[[Page 55277]]
its determination that this rule will not result in expenditures
exceeding $100 million in any one year, pursuant to 2 U.S.C. 1532(a).
The Agency need not complete any further statement under 2 U.S.C. 1532.
Comment: That commenter alleges the proposal fails to document
Centralized Regulatory Review Under E.O. 12866 section 3(f) and E.O.
14094.
Response: This action does not require this documentation as SIP
actions are exempt from review under E.O. 12866 and E.O. 14094 was
revoked.
Comment: That commenter insists the EPA's proposal fails to
document the basis for re-opening the comment period.
Response: The EPA is not required to document the basis for re-
opening a comment period; however, the public was made aware that the
public comment period was reopened in response to a comment.
Comment: That commenter claims the EPA's proposal does not comply
with E.O. 13272 as it does not document consultation with the Small
Business Administration (SBA) Office of Advocacy.
Response: This action will not have any significant economic impact
on a substantial number of small entities and merely approves State
choices as meeting the CAA and does not impose any additional
requirements beyond those required by State law, therefore consultation
with the SBA is not warranted.
IV. Incorporation by Reference
In this rule, the EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with the requirements of 1
CFR 51.5, the EPA is finalizing the incorporation by reference of the
Michigan Regulations described in section II of this preamble and set
forth in the amendments to 40 CFR part 52 below. The EPA has made, and
will continue to make, these documents generally available through
<a href="https://www.regulations.gov">https://www.regulations.gov</a>, and at the EPA Region 5 Office (please
contact the person identified in the FOR FURTHER INFORMATION CONTACT
section of this preamble for more information). Therefore, these
materials have been approved by the EPA for inclusion in the SIP, have
been incorporated by reference by the EPA into that plan, are fully
federally enforceable under CAA sections 110 and 113 as of the
effective date of the final rulemaking of the EPA's approval, and will
be incorporated by reference in the next update to the SIP
compilation.\1\

---------------------------------------------------------------------------
V. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, the EPA's role is to approve State choices,
provided that they meet the criteria of the CAA. Accordingly, this
action merely approves State law as meeting Federal requirements and
does not impose additional requirements beyond those imposed by State
law. For that reason, this action:
<bullet> Is not a significant regulatory action subject to review
by the Office of Management and Budget under Executive Order 12866 (58
FR 51735, October 4, 1993);
<bullet> Is not an Executive Order 14192 (90 FR 9065, February 6,
2025) regulatory action because this action is not significant under
Executive Order 12866;
<bullet> Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
<bullet> Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
<bullet> Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
<bullet> Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
<bullet> Is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it approves a State program;
<bullet> Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
<bullet> Is not subject to requirements of section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA.
In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where the EPA or an Indian Tribe
has demonstrated that a Tribe has jurisdiction. In those areas of
Indian country, the rule does not have Tribal implications and will not
impose substantial direct costs on Tribal governments or preempt Tribal
law as specified by Executive Order 13175 (65 FR 67249, November 9,
2000).
This action is subject to the Congressional Review Act, 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).
Under CAA section 307(b)(1), petitions for judicial review of this
action must be filed in the United States Court of Appeals for the
appropriate circuit by October 26, 2026. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this action for the purposes of judicial review nor
does it extend the time within which a petition for judicial review may
be filed, and shall not postpone the effectiveness of such rule or
action. This action may not be challenged later in proceedings to
enforce its requirements. (See section 307(b)(2).)
