{"abstract":"The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Missouri State Implementation Plan (SIP) received on March 19, 2025, that contain updates to the construction permit requirement regulations for stationary and portable air sources in Missouri that help ensure ambient air quality standards are met. The revisions to this rule include updating the fees for facilities applying for and receiving construction permits for air pollution sources; removing a subsection from the state rule that was never approved in the SIP; and making administrative wording changes. The EPA is correcting the state effective date in table C from the original proposal. These revisions do not interfere with the State's ability to attain or maintain the National Ambient Air Quality Standards (NAAQS), reasonable further progress (RFP) or other Clean Air Act (CAA) requirements. The EPA's final approval of this rule revision is being done in accordance with the requirements of the CAA.","action":"Final rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/04/23/2026-07884.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"52","title":40}],"citation":"91 FR 21724","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on May 26, 2026.","disposition_notes":null,"docket_ids":["EPA-R07-OAR-2025-3161","FRL-13099-02-R7"],"dockets":[],"document_number":"2026-07884","effective_on":"2026-05-26","end_page":21725,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/23/2026-07884.xml","html_url":"https://www.federalregister.gov/documents/2026/04/23/2026-07884/air-plan-approval-missouri-construction-permits-required","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-07884?publication_date=2026-04-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-23/2026-07884/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":66,"last_updated":"2026-04-24 00:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-23/pdf/2026-07884.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-07884.pdf?1776861912","publication_date":"2026-04-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/23/2026-07884.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"cromerr-submission-html","document_id":"EPA-R07-OAR-2025-3161-0003"},{"title":"6.060 EPA submittal pkg","document_id":"EPA-R07-OAR-2025-3161-0002"}],"comments_count":0,"agency_id":"EPA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R07-OAR-2025-3161","supporting_documents_count":2,"docket_id":"EPA-R07-OAR-2025-3161","document_id":"EPA-R07-OAR-2025-3161-0004","regulation_id_number":null,"title":"Air Plan Approval; Missouri; Construction Permits Required","checked_regulationsdotgov_at":"2026-04-24T04:55:03Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":21724,"subtype":null,"title":"Air Plan Approval; Missouri; Construction Permits Required","toc_doc":"Missouri; Construction Permits Required","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations","topics":["Air pollution control","Carbon monoxide","Environmental protection","Incorporation by reference","Intergovernmental relations","Lead","Ozone","Reporting and recordkeeping requirements","Sulfur oxides","Volatile organic compounds"],"type":"Rule","volume":91}
