On January 19, 2021, the U.S. Environmental Protection Agency (EPA) announced the availability of a final compliance guide that outlines which imported articles are covered by EPA’s July 2020 final significant new use rule (SNUR) that prohibits companies from manufacturing, importing, processing, or using certain long-chain per- and polyfluoroalkyl substances (PFAS) without prior EPA review and approval.  The final guide is “the official compliance guide for imported articles that may contain long-chain perfluoroalkyl carboxylate chemical substances as part of a surface coating.”  Specifically, the guide provides additional clarity on what is meant by a “surface coating,” identifies which entities are regulated, describes the activities that are required or prohibited, and summarizes the notification requirements of the final SNUR.  EPA states that there “are no significant changes between the final guidance document and the draft document, which was released for public comment in December.”  More information on the draft compliance guide is available in our December 14, 2020, memorandum, “EPA Publishes Draft Compliance Guide Addressing Surface Coatings under PFAS SNUR.”  Comments on the draft guide were due January 15, 2021.
