{"abstract":"On December 19, 1995, the EPA promulgated Clean Air Act (CAA) section 111(d)/129 emission guidelines for existing Municipal Waste Combustors (MWC) with the capacity to combust in aggregate greater than 35 megagrams (Mg) per day of municipal solid waste (MSW). Section 111(d) requires that states with designated facilities subject to these emission guidelines submit to the EPA plans to control the designated pollutants addressed in the guidelines. If no designated facility is located within a state, the state may submit a letter of certification to that effect, i.e., a negative declaration, in lieu of a plan. The EPA has received negative declarations from Iowa, Kansas, Missouri, and Nebraska regarding designated facilities in their states. Today the EPA is taking action to approve those negative declarations.","action":"Direct 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/1997/08/04/97-20475.html","cfr_references":[{"chapter":null,"citation_url":null,"part":62,"title":40}],"citation":"62 FR 41872","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This action is effective October 3, 1997, unless by September 3, 1997, adverse or critical comments are received.","disposition_notes":null,"docket_ids":["FRL-5868-3"],"dockets":[],"document_number":"97-20475","effective_on":"1997-10-03","end_page":41874,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1997/08/04/97-20475/approval-and-promulgation-of-state-plans-for-designated-facilities-and-pollutants-states-of-iowa","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/97-20475?publication_date=1997-08-04","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1997-08-04/97-20475/mods.xml","not_received_for_publication":null,"page_length":3,"page_views":{"count":19,"last_updated":"2026-07-25 22:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1997-08-04/pdf/97-20475.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1997-08-04","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1997/08/04/97-20475.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":41872,"subtype":null,"title":"Approval and Promulgation of State Plans for Designated Facilities and Pollutants; States of Iowa, Kansas, Missouri, and Nebraska","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":62}
