[EPA-R07-OAR-2025-0289; FRL-12821-01-R7]
Air Plan Approval; Missouri; Definitions and Common Reference Tables
AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Proposed rule.
SUMMARY:
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri State Implementation Plan (SIP) related to Definitions and Common Reference Tables used in Missouri rules. EPA has also previously approved this rule as part of the air planning and permitting program. Some of the definitions are associated with those programs, even though many of the definitions pertain only to the SIP. 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 July 28, 2025.

I. Written Comments
Submit your comments, identified by Docket ID No. EPA-R07-OAR-2025-0289, at https://www.regulations.gov. Once submitted, comments cannot be edited or removed from Regulations.gov . The EPA may publish any comment received to its public docket. Do not submit electronically any information you consider to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Multimedia submissions (audio, video, etc.) must be accompanied by a written comment. The written comment is considered the official comment and should include discussion of all points you wish to make. The EPA will generally not consider comments or comment contents located outside of the primary submission ( i.e. on the web, cloud, or other file sharing system). For additional submission methods, the full EPA public comment policy, information about CBI or multimedia submissions, and general guidance on making effective comments, please visit https://www.epa.gov/dockets/commenting-epa-dockets.
II. What is being addressed in this document?
The EPA is proposing to approve a SIP revision submitted by the State of Missouri on July 15, 2024. The revisions are to Title 10, Division 10 of the Code of State Regulations (CSR), 10 CSR 10-6.020 "Definitions and Common Reference Tables." The purpose of this state regulation is to provide definitions of key words and expressions used in Missouri rules for Chapters 1-6 statewide and provides common reference tables. The amendments to this rule add definitions and remove obsolete definitions since the last rule, either because the definitions have been added into an associated applicable rule, the terms are already defined in statute, or the applicable rule has been rescinded. Additionally, the list of Hazardous Air Pollutants and Exempt Volatile Organic Compounds is updated to match the current lists dictated in the CAA section 112(b)(1) and 40 CFR 51.100(s), respectively. 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 as well as EPA's analysis of the revisions can be found in the technical support document (TSD) and 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 from November 1, 2023, to December 14, 2023, and held a public hearing on December 7, 2023. The state of Missouri received two comments during the public comment period on 10 CSR 10-6.020. Missouri responded to both comments and revised the rule based on public comments prior to submitting to EPA, as noted in the State submission included in the docket for this action. As explained above and in more detail in the technical support document, which is part of this docket, the revision meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations.
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 10-6.020 "Definitions and Common Reference Tables." EPA's proposed action approves these amendments as part of the SIP, 111(d), and Title V programs even though many of the definitions only pertain to SIPs. 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 10-6.020 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 definitions of key words and expressions used in Missouri rules for Chapters 1-6 statewide and provides common reference tables. 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 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. );
[top] • 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).
