{"abstract":"The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri State Implementation Plan (SIP) received on February 10, 2026. The submission revises Missouri's regulation on construction permit exemptions in their Minor New Source Review (NSR) program. These revisions refine exemptions for emergency generators, update references to other rules, and update recordkeeping requirements. The EPA is proposing to approve this rule revision pursuant to the Clean Air Act (CAA).","action":"Proposed 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/2026/07/30/2026-15371.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"52","title":40}],"citation":"91 FR 48032","comment_url":null,"comments_close_on":"2026-08-31","correction_of":null,"corrections":[],"dates":"Comments must be received on or before August 31, 2026.","disposition_notes":null,"docket_ids":["EPA-R07-OAR-2026-5182","FRL-13486-01-R7"],"dockets":[{"supporting_documents":[{"title":"6.061 EPA submittal","document_id":"EPA-R07-OAR-2026-5182-0007"},{"title":"Email From Mark Leath","document_id":"EPA-R07-OAR-2026-5182-0006"},{"title":"EPA TECHNICAL SUPPORT DOCUMENT","document_id":"EPA-R07-OAR-2026-5182-0005"},{"title":"mosaics4s.epa.gov_cromerr-submission-html__3d22fe28-78f8-4755-a3d1-34c65ecd8f93","document_id":"EPA-R07-OAR-2026-5182-0004"},{"title":"MO-6061","document_id":"EPA-R07-OAR-2026-5182-0003"},{"title":"Answers to EPA questions on amendment to 10 CSR 10-6.061","document_id":"EPA-R07-OAR-2026-5182-0002"}],"agency_name":"EPA","documents":[{"comment_count":2,"comment_start_date":"2026-07-30","updated_at":"2026-09-01T01:56:33.247-04:00","comment_url":"https://www.regulations.gov/commenton/EPA-R07-OAR-2026-5182-0001","allow_late_comments":false,"id":"EPA-R07-OAR-2026-5182-0001","comment_end_date":"2026-09-01","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":6,"id":"EPA-R07-OAR-2026-5182","title":"MO-478 Air Plan Approval; Missouri; Construction Permit Exemptions"}],"document_number":"2026-15371","effective_on":null,"end_page":48033,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/07/30/2026-15371.xml","html_url":"https://www.federalregister.gov/documents/2026/07/30/2026-15371/air-plan-approval-missouri-construction-permit-exemptions","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-15371?publication_date=2026-07-30","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-07-30/2026-15371/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":184,"last_updated":"2026-10-24 20:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-07-30/pdf/2026-15371.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-15371.pdf?1785329117","publication_date":"2026-07-30","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/07/30/2026-15371.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"6.061 EPA submittal","document_id":"EPA-R07-OAR-2026-5182-0007"},{"title":"Email From Mark Leath","document_id":"EPA-R07-OAR-2026-5182-0006"},{"title":"EPA TECHNICAL SUPPORT DOCUMENT","document_id":"EPA-R07-OAR-2026-5182-0005"},{"title":"mosaics4s.epa.gov_cromerr-submission-html__3d22fe28-78f8-4755-a3d1-34c65ecd8f93","document_id":"EPA-R07-OAR-2026-5182-0004"},{"title":"MO-6061","document_id":"EPA-R07-OAR-2026-5182-0003"},{"title":"Answers to EPA questions on amendment to 10 CSR 10-6.061","document_id":"EPA-R07-OAR-2026-5182-0002"}],"comments_count":2,"agency_id":"EPA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R07-OAR-2026-5182","supporting_documents_count":6,"docket_id":"EPA-R07-OAR-2026-5182","document_id":"EPA-R07-OAR-2026-5182-0001","regulation_id_number":null,"title":"MO-478 Air Plan Approval; Missouri; Construction Permit Exemptions","checked_regulationsdotgov_at":"2026-09-02T08:55:04Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":48032,"subtype":null,"title":"Air Plan Approval; Missouri; Construction Permit Exemptions","toc_doc":"Missouri; Construction Permit Exemptions","toc_subject":"Air Quality State Implementation Plans; Approvals and Promulgations","topics":["Air pollution control","Carbon monoxide","Environmental protection","Incorporation by reference","Intergovernmental relations","Lead","Nitrogen dioxide","Ozone","Particulate matter","Reporting and recordkeeping requirements","Sulfur oxides","Volatile organic compounds"],"type":"Proposed Rule","volume":91}
