{"abstract":"The Environmental Protection Agency (EPA, the Agency) is amending the regulations promulgated as part of the National Recycling and Emission Reduction Program under section 608 of the Clean Air Act. EPA is amending those regulations to exempt certain refrigerant substitutes, listed as acceptable subject to use conditions in regulations promulgated as part of EPA's Significant New Alternative Policy program under section 612 of the Act, from the prohibition under section 608 on venting, release or disposal on the basis of current evidence that their venting, release or disposal does not pose a threat to the environment. Specifically, EPA is exempting from the venting prohibition isobutane (R-600a) and R-441A, as refrigerant substitutes in household refrigerators, freezers, and combination refrigerators and freezers, and propane (R-290), as a refrigerant substitute in retail food refrigerators and freezers (stand-alone units only).","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/2014/05/23/2014-12028.html","cfr_references":[{"chapter":null,"citation_url":null,"part":82,"title":40}],"citation":"79 FR 29682","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on June 23, 2014.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2012-0580","FRL-9911-42-OAR"],"dockets":[],"document_number":"2014-12028","effective_on":"2014-06-23","end_page":29691,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2014/05/23/2014-12028.xml","html_url":"https://www.federalregister.gov/documents/2014/05/23/2014-12028/protection-of-stratospheric-ozone-revision-of-the-venting-prohibition-for-specific-refrigerant","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2014-12028?publication_date=2014-05-23","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2014-05-23/2014-12028/mods.xml","not_received_for_publication":null,"page_length":10,"page_views":{"count":1560,"last_updated":"2026-08-25 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2014-05-23/pdf/2014-12028.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2014-12028.pdf?1400762895","publication_date":"2014-05-23","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2014/05/23/2014-12028.txt","regulation_id_number_info":{"2060-AM09":{"issue":"201110","html_url":"https://www.federalregister.gov/regulations/2060-AM09/protection-of-stratospheric-ozone-amendments-to-the-section-608-leak-repair-regulations","title":"Protection of Stratospheric Ozone: Amendments to the Section 608 Leak Repair Regulations","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201110&RIN=2060-AM09&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2060-AM09"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Adequacy Status of the Cleveland/Akron, Ohio and the Columbus, Ohio Submitted 8-Hour Ozone Redesignation and Maintenance Plans for Transportation Conformity Purposes","document_id":"EPA_FRDOC_0001-6733"},{"title":"DELETE","document_id":"EPA_FRDOC_0001-6642"},{"title":"Agency Information Collection Activities; Proposals, Submissions, and Approvals","document_id":"EPA_FRDOC_0001-6334"},{"title":"Literature Search for 2,3,7,8-Tetrachlorodibenzo-p-Dioxin(TCDD) Dose-Response Studies for Use in an Upcoming Expert Panel Workshop","document_id":"EPA_FRDOC_0001-6019"},{"title":"Regulatory Agenda Semiannual Regulatory Agenda","document_id":"EPA_FRDOC_0001-6015"},{"title":"Correction to MVEBs for the Indiana and Ohio Portions of the Cincinnati-Hamilton, Ohio/Kentucky/Indiana, Submitted 8-Hour Ozone Attainment Demonstration","document_id":"EPA_FRDOC_0001-5132"},{"title":"Pesticides; tolerances in food, animal feeds, and raw agricultural commodities: Pyriproxyfen","document_id":"EPA_FRDOC_0001-3649"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA_FRDOC_0001","supporting_documents_count":7,"docket_id":"EPA_FRDOC_0001","regulation_id_number":null,"title":"Recently Posted EPA Rules and Notices from FR Feed.","checked_regulationsdotgov_at":"2014-06-12T06:00:45Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":29682,"subtype":null,"title":"Protection of Stratospheric Ozone: Revision of the Venting Prohibition for Specific Refrigerant Substitutes","toc_doc":"Venting Prohibition for Specific Refrigerant Substitutes","toc_subject":"Protection of Stratospheric Ozone:","topics":["Administrative practice and procedure","Air pollution control","Environmental protection","Recycling","Reporting and recordkeeping requirements"],"type":"Rule","volume":79}
