{"abstract":"This action revises EPA's definition of volatile organic compounds (VOC) for purposes of preparing State implementation plans (SIP's) to attain the national ambient air quality standards (NAAQS) for ozone under title I of the Clean Air Act (Act) and for any Federal implementation plan (FIP) for an ozone nonattainment area. This revision would add 16 compounds (shown in Table 2) to the list of compounds excluded from the definition of VOC on the basis that these compounds have negligible contribution to tropospheric ozone formation. These compounds have potential for use as refrigerants, aerosol propellants, fire extinguishants, blowing agents and solvents.","action":"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/1997/08/25/97-22510.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"51","title":40}],"citation":"62 FR 44900","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective September 24, 1997.","disposition_notes":null,"docket_ids":["FRL-5880-9"],"dockets":[],"document_number":"97-22510","effective_on":"1997-09-24","end_page":44903,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1997/08/25/97-22510/air-quality-revision-to-definition-of-volatile-organic-compoundsexclusion-of-16-compounds","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/97-22510?publication_date=1997-08-25","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1997-08-25/97-22510/mods.xml","not_received_for_publication":null,"page_length":4,"page_views":{"count":31,"last_updated":"2026-10-25 04:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1997-08-25/pdf/97-22510.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1997-08-25","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1997/08/25/97-22510.txt","regulation_id_number_info":{"2060-AG70":{"issue":"199710","html_url":"https://www.federalregister.gov/regulations/2060-AG70/revision-to-definition-of-volatile-organic-compounds-voc-exclusion-of-16-compounds","title":"Revision to Definition of Volatile Organic Compounds (VOC)--Exclusion of 16 Compounds","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=199710&RIN=2060-AG70&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AG70"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":44900,"subtype":null,"title":"Air Quality: Revision to Definition of Volatile Organic CompoundsExclusion of 16 Compounds","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":62}
