On March 29, 2023, the U.S. Environmental Protection Agency (“EPA”), published in the Federal Register its proposed national drinking water standards for six PFAS compounds. Official publication of the proposed regulation comes on the heels of the Agency’s announcement on March 14, 2023, that it is proposing Maximum Contaminant Levels (MCLs) and Maximum Contaminant Level Goals (MCLGs) for PFOA, PFOS, PFNA, PFHxS, PFBS, and GenX Chemicals. Official publication of the proposed rule triggers the start of the public comment period, which will remain open until May 30, 2023. Members of the public are invited to comment on the proposed rule through the close of the comment period. The EPA is also holding a virtual public hearing on the proposed rule on May 4, 2023.
