**ACTION:**
Final rule.
**SUMMARY:**
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Missouri State Implementation Plan (SIP) and the Missouri Operating Permits Program related to Reporting Emission Data, Emission Fees, and Process Information.

These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's final approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
**DATES:**
This final rule is effective on March 30, 2026.

**I. What is being addressed in this document?**
The EPA is approving revisions to the Missouri SIP and the state Title V Operating Permits Program, 10-6.110 “Reporting Emission Data, Emission Fees, and Process Information,” submitted to the EPA on March 19, 2025. The amendments to this rule set emission fees and a base fee for calendar years 2025-2028 and beyond, add 1-Bromopropane to the category 1 Hazardous Air Pollutant list in table 1, update two publication dates for material that is incorporated by reference, and make minor administrative changes to the rule. The EPA finds that these revisions meet the requirements of the CAA, do not impact the stringency of the SIP, and do not adversely impact air quality. The full text of the rule revisions can be found in the state submittal included in this docket.
**II. Have the requirements for approval of a SIP revision been met?**
The State's submission has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The submission also satisfied the completeness criteria of 40 CFR part 51, appendix V. The State provided public notice on this SIP revision and related amendments to their Title V Operating Permits Program, from July 15, 2024, to September 5, 2024, and held a public hearing on August 29, 2024. The State of Missouri received one supportive comment during the public comment period on 10 CSR 10-6.110. The revision meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations, and is consistent with applicable EPA requirements in title V of the CAA and 40 CFR part 70.
**III. The EPA's Response to Comments**
The public comment period on the EPA's proposed rule opened November 28, 2025, the date of its publication in the *Federal Register* and closed on December 29, 2025 (90 FR 54605). During this period, the EPA received no comments.
**IV. What action is the EPA taking?**
The EPA is taking final action to amend the Missouri SIP and the Missouri Title V Operating Permits Program by approving the State's request to revise 10 CSR 10-6.110 “Reporting Emission Data, Emission Fees, and Process Information.” This final action approves these amendments as part of the SIP, except for subsection (3)(A), which is not included in the SIP. However, the entire rule revision is being submitted for inclusion in the Missouri Title V Operating Permits program. These revisions update the emissions fee for permitted sources in subsection (3)(A) and the emission reporting years in table 4 of section (4)(B), as set by Missouri statute. Specifically, section (3)(A) revises the emission fees section, which is approved under the Operating Permits Program only and is not being approved in the Missouri SIP. The revised emission fees section updates the emissions fee for permitted sources as set by Missouri statute per ton of air pollution emitted annually for calendar years 2025-2028 and beyond and is effective January 1, 2026.
**V. Incorporation by Reference**
In this document, 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 Missouri rule 10 CSR 10-6.110 discussed in section I. of this preamble and as set forth below in the amendments to 40 CFR part 52. The purpose of this State regulation is to provide procedures for reporting emission-related information and establish emission fees for the purpose of state air resource planning. The EPA has made, and will continue to make, these materials generally available through *https://www.regulations.gov* and at the EPA Region 7 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 EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.

**VI. 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:
• 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);
• 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 (CRA), 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 April 27, 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)).
