{"abstract":"Under the Toxic Substances Control Act (TSCA), EPA is proposing to amend a significant new use rule (SNUR) for perfluoroalkyl sulfonate (PFAS) chemical substances to add PFAS chemical substances that have completed the TSCA new chemical review process but have not yet commenced production or import, and to designate (for all listed PFAS chemical substances) processing as a significant new use. EPA is also proposing a SNUR for long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances that would designate manufacturing, importing, or processing for use as part of carpets or for treating carpet (e.g., for use in the carpet aftercare market) as a significant new use. For this SNUR, EPA is also proposing to make the article exemption inapplicable to the import of LCPFAC chemical substances as part of carpets. Persons subject to these SNURs would be required to notify EPA at least 90 days before commencing any significant new use. The required notifications would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.","action":"Proposed 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/2012/08/15/2012-19952.html","cfr_references":[{"chapter":null,"citation_url":null,"part":721,"title":40}],"citation":"77 FR 48924","comment_url":null,"comments_close_on":"2012-10-15","correction_of":null,"corrections":[],"dates":"Comments must be received on or before October 15, 2012.","disposition_notes":null,"docket_ids":["EPA-HQ-OPPT-2012-0268","FRL-9358-7"],"dockets":[],"document_number":"2012-19952","effective_on":null,"end_page":48934,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2012/08/15/2012-19952.xml","html_url":"https://www.federalregister.gov/documents/2012/08/15/2012-19952/perfluoroalkyl-sulfonates-and-long-chain-perfluoroalkyl-carboxylate-chemical-substances-proposed","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2012-19952?publication_date=2012-08-15","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2012-08-15/2012-19952/mods.xml","not_received_for_publication":null,"page_length":11,"page_views":{"count":646,"last_updated":"2026-06-27 12:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2012-08-15/pdf/2012-19952.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2012-19952.pdf?1344948500","publication_date":"2012-08-15","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2012/08/15/2012-19952.txt","regulation_id_number_info":{"2070-AJ95":{"issue":"201304","html_url":"https://www.federalregister.gov/regulations/2070-AJ95/significant-new-use-rule-for-perfluoroalkyl-sulfonates-and-long-chain-perfluoroalkyl-carboxylates-us","title":"Significant New Use Rule for Perfluoroalkyl Sulfonates and Long-Chain Perfluoroalkyl Carboxylates Used as Part of Carpets","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201304&RIN=2070-AJ95&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2070-AJ95"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Illustrative List of LCPFAC Chemical Substances","document_id":"EPA-HQ-OPPT-2012-0268-0037"},{"title":"PFC Action Plan","document_id":"EPA-HQ-OPPT-2012-0268-0036"},{"title":"Economic Analysis for Final Rule","document_id":"EPA-HQ-OPPT-2012-0268-0035"},{"title":"SPI Meeting 12.19.2012","document_id":"EPA-HQ-OPPT-2012-0268-0031"},{"title":"DuPont Meeting August 21, 2012","document_id":"EPA-HQ-OPPT-2012-0268-0026"},{"title":"This document contains proprietary information and should not have been posted to the docket.","document_id":"EPA-HQ-OPPT-2012-0268-0025"},{"title":"Economic Analysis","document_id":"EPA-HQ-OPPT-2012-0268-0024"},{"title":"Ref. 21 Non-Proprietary Market Profile for Perfluorinated Chemicals (PFCs) Used as Part of Carpets","document_id":"EPA-HQ-OPPT-2012-0268-0023"},{"title":"Ref. 13 Influence of Carbon Chain Length on the Hepatic Effects of Perfluorinated Fatty Acids.
