The U.S. Environmental Protection Agency (EPA) continues to make addressing per- and polyfluoroalkyl substances (PFAS) in the environment an active and ongoing priority. As part of these efforts, today, EPA is issuing a final guidance document that outlines which imported articles are covered by the agency's?July 2020 final rule?that prohibits companies from manufacturing, importing, processing, or using certain long-chain PFAS without prior EPA review and approval. There are no significant changes between the final guidance document and the draft document, which was released for public comment in December.
