occurred since July 2020. EPA proposed to approve this submittal, which
will result in consistent requirements of rules at both the State and
Federal level, on July 16, 2025, and received no adverse comments.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,''
``us,'' or ``our'' is used, we mean EPA.

I. Background Information

On July 16, 2025 (90 FR 31918), EPA proposed to approve Minnesota's
October 1, 2021, SIP revision request. The revision included amendments
to permit rules, clarifications of permit requirements for small
sources of air emissions, updates to rules governing small air
pollution sources and the addition of four categories of conditionally
exempt sources. Minnesota completed a State rulemaking to clarify
exempt source and insignificant activities rules in 2019. This SIP
revision codifies those amendments to State law in the Minnesota SIP.
An explanation of the Clean Air Act requirements, a detailed analysis
of the revisions, and EPA's reasons for proposing approval were
provided in the notice of proposed rulemaking (NPRM) and will not be
restated here. The public comment period for this proposed rule ended
on August 15, 2025. EPA received one comment in support of the proposed
approval. The comment received is included in the docket for this
action.
We do not consider the comment to be germane or relevant to this
action and, therefore, not adverse to this action. Therefore, we are
finalizing our action as proposed.

[[Page 52246]]

II. Final Action

EPA is approving MPCA's October 1, 2021, submittal, as a revision
to its existing SIP. Specifically, EPA is approving and incorporating
by reference the following rule sections as adopted on January 7, 2019,
and published electronically on April 3, 2019, into the Minnesota SIP
at 40 CFR 52.1220(c):
<bullet> Chapter 7005 Definitions and Abbreviations, section
7005.0100;
<bullet> Chapter 7007 Air Emission Permits, sections 7005.0100,
7007.0300, 7007.0400, 7007.0850, 7007.1144, 7007.1145, 7007.1147,
7007.1250, and 7007.1300;
<bullet> Chapter 7008 Conditionally Exempt Stationary Sources and
Conditionally Insignificant Activities, sections 7008.0100, 7008.0200,
7008.2100, 7008.2200, 7008.2300, 7008.2400, 7008.2500, 7008.2600,
7008.4000, 7008.4100, and 7008.4110;
<bullet> Chapter 7011 Standards for Stationary Sources, sections
7011.0561, 7011.1201, and 7011.2300; and
<bullet> Chapter 7019 Emission Inventory Requirements, section
7019.3020.
EPA is also removing rule 7023 from the SIP as this rule is
obsolete given the November 2019 expiration of the CO Maintenance area.

III. Incorporation by Reference

In this rule, EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with requirements of 1 CFR
51.5, EPA is finalizing the incorporation by reference of the Minnesota
Regulations described in section II. of this preamble and set forth in
the amendments to 40 CFR part 52 below. 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 EPA for inclusion in the SIP, have been incorporated
by reference by EPA into that plan, are fully federally enforceable
under sections 110 and 113 of the Clean Air Act as of the effective
date of the final rulemaking of 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).
---------------------------------------------------------------------------

IV. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Clean Air Act
and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve State
choices, provided they meet the criteria of the Clean Air Act.
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 subject to Executive Order 14192 (90 FR 9065,
February 6, 2025) because SIP actions are exempt from review 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 Clean Air Act.
In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where 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 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 section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by January 20, 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).)
