{"abstract":"The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the Department of Energy and Environment (DOEE, the \"Department\") on behalf of the District of Columbia (DC, the \"District\"). The revisions pertain to creating a synthetic minor permit program and resolving the regulatory differences between the District's current regulations and those regulations approved previously in Chapters 1 and 2 of the Air Quality Regulations. The intended effect of this action is to enable DC to create federally enforceable synthetic minor permit conditions for sources of criteria pollutants pursuant to section 110 of the Clean Air Act (CAA, the \"Act\"). This action is being taken under the 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/2025/11/20/2025-20416.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"52","title":40}],"citation":"90 FR 52305","comment_url":null,"comments_close_on":"2025-12-22","correction_of":null,"corrections":[],"dates":"Written comments must be received on or before December 22, 2025.","disposition_notes":null,"docket_ids":["EPA-R03-OAR-2025-0734","FRL-13009-01-R3"],"dockets":[{"supporting_documents":[{"title":"state submittal","document_id":"EPA-R03-OAR-2025-0734-0002"}],"agency_name":"EPA","documents":[{"comment_count":3,"comment_start_date":"2025-11-20","updated_at":"2025-12-23T00:05:12.303-05:00","comment_url":"https://www.regulations.gov/commenton/EPA-R03-OAR-2025-0734-0001","allow_late_comments":false,"id":"EPA-R03-OAR-2025-0734-0001","comment_end_date":"2025-12-23","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"EPA-R03-OAR-2025-0734","title":"SIP Addressing Emissions During SSM and SIP Discrepancies in DCMR Chapters 1 and 2"}],"document_number":"2025-20416","effective_on":null,"end_page":52308,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2025/11/20/2025-20416.xml","html_url":"https://www.federalregister.gov/documents/2025/11/20/2025-20416/air-plan-approval-district-of-columbia-creation-of-synthetic-minor-permit-program","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2025-20416?publication_date=2025-11-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2025-11-20/2025-20416/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":171,"last_updated":"2026-08-25 22:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-11-20/pdf/2025-20416.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-20416.pdf?1763559921","publication_date":"2025-11-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2025/11/20/2025-20416.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"state submittal","document_id":"EPA-R03-OAR-2025-0734-0002"}],"comments_count":3,"agency_id":"EPA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-R03-OAR-2025-0734","supporting_documents_count":1,"docket_id":"EPA-R03-OAR-2025-0734","document_id":"EPA-R03-OAR-2025-0734-0001","regulation_id_number":null,"title":"SIP Addressing Emissions During SSM and SIP Discrepancies in DCMR Chapters 1 and 2","checked_regulationsdotgov_at":"2025-12-24T09:55:03Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":52305,"subtype":null,"title":"Air Plan Approval; District of Columbia; Creation of Synthetic Minor Permit Program","toc_doc":"District of Columbia; Creation of Synthetic Minor Permit Program","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":90}
