Title: Long-Chain Perfluoroalkyl Carboxylate and Perfluoroalkyl Sulfonate Chemical Substances; Significant New Use Rule 

EPA is developing a significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances, and for perfluorooctanoic acid (PFOA) or its salts. On January 21, 2015, EPA proposed to amend a SNUR for LCPFAC chemical substances by designating as a significant new use manufacturing (including importing) or processing of an identified subset of LCPFAC chemical substances for any use that will not be ongoing after December 31, 2015, and all other LCPFAC chemicals substances for which there are currently no ongoing uses. EPA also proposed to make inapplicable the exemption for persons who import LCPFAC chemical substances as part of articles. In addition, the EPA proposed to amend a SNUR for perfluoroalkyl sulfonate (PFAS) chemical substances that would make inapplicable the exemption for persons who import PFAS chemical substances as part of carpets. Persons subject to these SNURs would be required to notify the EPA at least 90 days before commencing such manufacture or processing. The required notifications would initiate EPA's evaluation of the intended use within the applicable review period. Manufacture and processing for the significant new use would be unable to commence until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required in association with that determination. EPA intends to issue a supplemental proposal for this SNUR following changes to TSCA brought about by the Frank R. Lautenberg Chemical Safety for the 21st Century Act in June 2016.
