{"abstract":"This action promulgates amendments to the \"generic\" maximum achievable control technology (MACT) standards to add national emission standards for hazardous air pollutants (NESHAP) for four additional source categories: Cyanide Chemicals Manufacturing, Carbon Black Production, Ethylene Production, and Spandex Production. The generic MACT standards provide a structural framework that allows source categories with similar emission types and MACT control requirements to be covered under one subpart, thus promoting regulatory consistency in NESHAP development. The EPA has identified these four source categories as major sources of hazardous air pollutants (HAP), including cyanide compounds, acrylonitrile, acetonitrile, carbonyl sulfide, carbon disulfide, benzene, 1,3 butadiene, toluene, and 2,4 toluene diisocyanate (TDI). Benzene is a known human carcinogen, and 1,3 butadiene is considered to be a probable human carcinogen. The other pollutants can cause noncancer health effects in humans. These standards will implement section 112(d) of the Clean Air Act (CAA) by requiring all major sources to meet HAP emission standards reflecting the application of MACT. This action also promulgates NESHAP for the heat exchange systems and wastewater operations at ethylene manufacturing facilities.","action":"Final rule; amendments.","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/2002/07/12/02-12841.html","cfr_references":[{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"67 FR 46258","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"July 12, 2002.","disposition_notes":null,"docket_ids":["FRL-7215-7"],"dockets":[],"document_number":"02-12841","effective_on":null,"end_page":46289,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2002/07/12/02-12841.xml","html_url":"https://www.federalregister.gov/documents/2002/07/12/02-12841/national-emission-standards-for-hazardous-air-pollutants-generic-maximum-achievable-control","images":{"ER12JY02.015":{"large":"https://img.federalregister.gov/ER12JY02.015/ER12JY02.015_large.png","medium":"https://img.federalregister.gov/ER12JY02.015/ER12JY02.015_medium.png","original_size":"https://img.federalregister.gov/ER12JY02.015/ER12JY02.015_original_size.png"}},"images_metadata":{"ER12JY02.015":{"large":{"identifier":"ER12JY02.015","content_type":"image/png","size":7297,"width":603,"sha":"a4e73510ffbe444f28442f48b7cbbc0c","url":"https://img.federalregister.gov/ER12JY02.015/ER12JY02.015_large.png","height":148},"medium":{"identifier":"ER12JY02.015","content_type":"image/png","size":2555,"width":284,"sha":"600a3b1109b880e187b1cae2013bd1e4","url":"https://img.federalregister.gov/ER12JY02.015/ER12JY02.015_medium.png","height":70},"original_size":{"identifier":"ER12JY02.015","content_type":"image/png","size":1662,"width":257,"sha":"7559645585bc60b056c5210e2685a339","url":"https://img.federalregister.gov/ER12JY02.015/ER12JY02.015_original_size.png","height":63}}},"json_url":"https://www.federalregister.gov/api/v1/documents/02-12841?publication_date=2002-07-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2002-07-12/02-12841/mods.xml","not_received_for_publication":null,"page_length":32,"page_views":{"count":903,"last_updated":"2026-07-27 10:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2002-07-12/pdf/02-12841.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2002-07-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2002/07/12/02-12841.txt","regulation_id_number_info":{"2060-AH68":{"issue":"200204","html_url":"https://www.federalregister.gov/regulations/2060-AH68/neshap-generic-mact-for-carbon-black-ethylene-cyanide-and-spandex","title":"NESHAP: Generic MACT for Carbon Black, Ethylene, Cyanide and Spandex","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200204&RIN=2060-AH68&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AH68"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":46258,"subtype":null,"title":"National Emission Standards for Hazardous Air Pollutants: Generic Maximum Achievable Control Technology","toc_doc":"Cyanide chemicals, carbon black, ethylene, and spandex","toc_subject":"Air pollutants, hazardous; national emission standards:","topics":["Administrative practice and procedure","Air pollution control","Environmental protection","Hazardous substances","Intergovernmental relations","Reporting and recordkeeping requirements"],"type":"Rule","volume":67}
