{"abstract":"EPA is seeking comments on a variety of options for establishing an allowance allocation system to control the U.S. consumption of class II controlled substances, the hydrochlorofluorocarbons (HCFCs), in accordance with U.S. obligations under the Montreal Protocol on Substances that Deplete the Ozone Layer (Protocol). Under the Protocol, the United States is obligated to limit HCFC consumption (defined by the Protocol and this notice as production plus imports, minus exports) under a specific cap, which will be reduced in a step-wise fashion over time. To ensure that the U.S. does not exceed this internationally mandated cap, EPA is presenting many options for establishing a future HCFC allowance allocation system. EPA is considering, among other things, an option where the allowance system would become effective only under certain conditions, i.e., once a specified percentage of the current U.S. HCFC cap has been reached or exceeded.","action":"Advance Notice of Proposed Rulemaking.","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/1999/04/05/99-8258.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"82","title":40}],"citation":"64 FR 16373","comment_url":null,"comments_close_on":"1999-06-04","correction_of":null,"corrections":[],"dates":"Comments on this advanced notice of proposed rulemaking must be received on or before June 4, 1999.","disposition_notes":null,"docket_ids":["FRL-6319-2"],"dockets":[],"document_number":"99-8258","effective_on":null,"end_page":16383,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1999/04/05/99-8258/protection-of-stratospheric-ozone-allowance-system-for-controlling-hcfc-production-import-and-export","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/99-8258?publication_date=1999-04-05","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1999-04-05/99-8258/mods.xml","not_received_for_publication":null,"page_length":11,"page_views":{"count":37,"last_updated":"2026-10-23 02:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1999-04-05/pdf/99-8258.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1999-04-05","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1999/04/05/99-8258.txt","regulation_id_number_info":{"2060-AH67":{"issue":"200210","html_url":"https://www.federalregister.gov/regulations/2060-AH67/protection-of-stratospheric-ozone-allowance-system-for-controlling-hcfc-production-import-and-export","title":"Protection of Stratospheric Ozone: Allowance System for Controlling HCFC Production, Import and Export","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200210&RIN=2060-AH67&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AH67"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T02:44:42Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":16373,"subtype":null,"title":"Protection of Stratospheric Ozone: Allowance System for Controlling HCFC Production, Import and Export","toc_doc":null,"toc_subject":null,"topics":[],"type":"Proposed Rule","volume":64}
