EPA Issues Final SNUR for LCPFAC and Perfluoroalkyl Sulfonate Chemical Substances

Lynn L. Bergeson

On July 27, 2020, the U.S. Environmental Protection Agency (EPA) promulgated a final significant use rule (SNUR) for long-chain perfluoroalkyl carboxylate (LCPFAC) and perfluoroalkyl sulfonate chemical substances.  85 Fed. Reg. 45109.  The final SNUR requires persons to notify EPA at least 90 days before commencing the manufacture (including import) or processing of these chemical substances for the significant new uses described in the notice.  The required significant new use notification initiates EPA’s evaluation of the conditions of use associated with the significant new use.  Manufacturing (including import) or processing for the significant new use are prohibited from commencing 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 notes that as with any SNUR, the final rule excludes ongoing uses as ongoing uses cannot be subject to a SNUR.  The final rule will be effective September 25, 2020.  More information on the final SNUR is available in our July 27, 2020, memorandum.
