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 NO2 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 NO2 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 https://www.regulations.gov, 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: 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); Is not subject to Executive Order 14192 (90 FR 9065, February 6, 2025) because SIP actions are exempt from review under Executive Order 12866; Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); 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.); 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); Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); [[Page 16551]] Is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it approves a State program; Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); and 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).)
