These revisions represent changes to the air permitting rules the Ohio Environmental Protection Agency (Ohio EPA) adopted on March 1, 2023, and July 25, 2025, which became effective at the State level on March 11, 2023, and August 14, 2025, respectively. These revisions will result in consistent requirements of rules at both the State and Federal level. The EPA proposed to approve this action on January 9, 2026, and received no adverse comments.

I. Background Information
On January 9, 2026 (91 FR 937), the EPA proposed to approve
revisions submitted on March 19, 2025, and August 5, 2025, to Ohio's
air permitting rules into the SIP under the CAA, including
incorporating by reference Ohio rule(s) 3745-31-01 [with the exception
of OAC 3745-31-01(A)(8), (E)(3)(b)(ii) and (iii), (M)(10)(a)(ii),
(P)(12), (Q), and (S)(11)], 3745-31-02, 3745-31-03 [with the exception
of OAC 3745-31-03(B)(1)(p)], 3745-31-05 [with the exception of OAC
3745-31-05(E)], 3745-31-06, 3745-31-07, 3745-31-09, 3745-31-10, 3745-
31-11, 3745-31-12, 3745-31-13 [with the exception of OAC 3745-31-
13(H)(1)(c)], 3745-31-14, 3745-31-15, 3745-31-16, 3745-31-17, 3745-31-
18, 3745-31-19, 3745-31-20, 3745-31-21, 3745-31-22 [with the exception
of OAC 3745-31-22(A)(3)(b)], 3745-31-23 [with the exception of the 1-
hour NO<INF>2</INF> SIL in 3745-31-23(A)], 3745-31-24 [with the
exception of OAC 3745-31-24(F)], 3745-31-25, 3745-31-26 [with the
exception of OAC 3745-31-26(D)], 3745-31-27 [with the exception of OAC
3745-31-27(A)(1)(b)], 3745-31-28, 3745-31-29, 3745-31-30, and 3745-31-
32. 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
public comment period for this proposed rule ended on February 9, 2026.
The EPA received no comments on the proposal.
II. Final Action
The EPA is approving Ohio EPA's March 19, 2025, and August 5, 2025,
submittals as revisions to its existing SIP. The EPA finds that the
revisions are consistent with Federal requirements. As requested by
Ohio EPA, the following provisions are not included in this proposed
approval: OAC 3745-31-01(A)(8), (E)(3)(b)(ii) and (iii),
(M)(10)(a)(ii), (P)(12), (Q), and (S)(11); 3745-31-03(B)(1)(p); 3745-
31-05(E); 3745-31-13(H)(1)(c); 3745-31-22(A)(3)(b); 1-hour
NO<INF>2</INF> SIL in 3745-31-23(A); 3745-31-24(F); 3745-31-26(D);
3745-31-27(A)(1)(b); and 3745-31-34(B), (C), and (D).
III. Incorporation by Reference
In this rule, the EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with requirements of 1 CFR
51.5, the EPA is finalizing the incorporation by reference of the Ohio
Regulations described in section I. 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 sections 110 and 113 of the CAA 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).
---------------------------------------------------------------------------
IV. 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 these reasons, 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);
[[Page 16551]]
<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 section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by June 1, 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).)
