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.

Air Plan Approval; Michigan; 2015 Ozone Moderate Reasonably 
Available Control Technology

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

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-
0235 (for NO<INF>X</INF> RACT). All documents in the docket are listed

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 
336.1608; R 336.1609; R 336.1610; R 336.1610a; R 336.1611; R 336.1618; 
R 336.1620; R 336.1620a; R 336.1621; R 336.1621a; R 336.1622; R 
336.1623; R 336.1624; R 336.1624a; R 336.1625; R 336.1627; R 336.1628; 
R 336.1629; R 336.1630; R 336.1631; R 336.1632, except for R 
336.1632(9); R 336.1633; R 336.1634; R 336.1635; R 336.1636; R 
336.1637; R 336.1638; R 336.1639; R 336.1640; R 336.1641; R 336.1642; R 
336.1643; R 336.1644; R 336.1660; R 336.1661 (Rescinded); R 336.1662; 
effective April 18, 2023; R 336.1840; R 336.1841,except for R 
336.1841(8); R 336.1842, except for R 336.1842(10); R 336.1843; 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\

    \1\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

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).)
