{"abstract":"EPA is proposing to approve revisions to the Imperial County Air Pollution Control District (ICAPCD) and the Monterey Bay Unified Air Pollution Control District (MBUAPCD) portions of the California State Implementation Plan (SIP). The ICAPCD revision concerns the emission of particulate matter (PM-10) from agricultural burning. The MBUAPCD revision concerns the emission of PM-10 from incinerator burning. We are proposing to approve local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).","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/2003/01/31/03-2176.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"68 FR 4977","comment_url":null,"comments_close_on":"2003-03-03","correction_of":null,"corrections":[],"dates":"Any comments on this proposal must arrive by March 3, 2003.","disposition_notes":null,"docket_ids":["CA 273-0370b","FRL-7441-6"],"dockets":[],"document_number":"03-2176","effective_on":null,"end_page":4977,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2003/01/31/03-2176.xml","html_url":"https://www.federalregister.gov/documents/2003/01/31/03-2176/revisions-to-the-california-state-implementation-plan-imperial-county-air-pollution-control-district","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/03-2176?publication_date=2003-01-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2003-01-31/03-2176/mods.xml","not_received_for_publication":null,"page_length":1,"page_views":{"count":1,"last_updated":"2026-04-04 18:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2003-01-31/pdf/03-2176.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2003-01-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2003/01/31/03-2176.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":4977,"subtype":null,"title":"Revisions to the California State Implementation Plan, Imperial County Air Pollution Control District and Monterey Bay Unified Air Pollution Control District","toc_doc":"California","toc_subject":"Air quality implementation plans; approval and promulgation; various States:","topics":[],"type":"Proposed Rule","volume":68}
