[Public Comment] Proposed PFAS National Primary Drinking Water Regulation

May 30, 2023

EPA announced the proposed National Primary Drinking Water Regulation (NPDWR) for six PFAS including perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide dimer acid (HFPO-DA, commonly known as GenX Chemicals), perfluorohexane sulfonic acid (PFHxS), and perfluorobutane sulfonic acid (PFBS). The proposed PFAS NPDWR does not require any actions until it is finalized. EPA anticipates finalizing the regulation by the end of 2023. EPA expects that if fully implemented, the rule will prevent thousands of deaths and reduce tens of thousands of serious PFAS-attributable illnesses.

EPA is requesting public comment on the proposed regulation. The public comment period is now open following the proposed rule publishing in the Federal Register on March 29, 2023. Public comments can be provided at www.regulations.gov under Docket ID: EPA-HQ-OW-2022-0114. Comments must be submitted during the public comment period that ends on May 30, 2023. Information on submitting comments to EPA dockets can be found here.

EPA held an informational general overview webinar of the proposed PFAS NPDWR on March 16, 2023, and another informational webinar about the proposed PFAS NPDWR specifically for water utilities and the drinking water professional community on March 29, 2023.
