# Identification of plan.
**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Proposed rule.
**SUMMARY:**
The Environmental Protection Agency (EPA) is proposing approval of revisions to the Missouri State Implementation Plan (SIP), and Operating Permits Program related to Reporting Emission Data, Emission Fees, and Process Information. The revisions 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. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
**DATES:**
Comments must be received on or before December 29, 2025.

**II. What is being addressed in this document?**
The EPA is proposing to approve revisions to the Missouri SIP and 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 proposes to find 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.
**III. Have the requirements for approval of a SIP revision been met?**
The State 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 supporting 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.
**IV. What action is the EPA taking?**
The EPA is proposing to amend the Missouri SIP by approving the State's request to revise 10 CSR 10-6.110 “Reporting Emission Data, Emission Fees, and Process Information.” The EPA's proposed 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 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 proposed to be 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.
We are processing this as a proposed action because we are soliciting comments on this proposed action. Final rulemaking will occur after consideration of any comments.
**V. Incorporation by Reference**
In this document, the EPA is proposing to include regulatory text in an EPA final rule that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to finalize the incorporation by reference of the Missouri rule 10 CSR 10-6.110 discussed in section II. of this preamble and as set forth below in the proposed amendments to 40 CFR part 52. The purpose of this state regulation is to provide procedures for reporting emission related information and establishing 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).
**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, 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 Orders 12866 (58 FR 51735, October 4, 1993);
• Is not subject to Executive Order 14192 (90 FR 9065, February 6, 2025) because State Implementation Plan 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 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).
