Perfluoroalkyl Sulfonates - Significant New Use Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Perfluoroalkyl Sulfonates - Significant New Use Rule (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is amending a significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) to include certain additional perfluoroalkyl sulfonate (PFAS) chemicals. EPA is amending the PFAS SNUR at 40 CFR 721.9582 by adding a new Table 3 which includes the PFAS chemicals currently on the public TSCA Inventory that are not already covered by the SNUR. This rule requires manufacturers, including importers, to notify EPA at least 90 days before commencing the manufacture or import of the PFAS chemicals listed in Table 3 of the regulatory text for the significant new uses described in this document on or after November 8, 2007. EPA believes that this action is appropriate because these chemical substances may be hazardous to human health and the environment. This required notice will provide EPA the opportunity to evaluate intended significant new uses and associated activities before they occur and, if necessary, to prohibit or limit those uses or activities.
