EPA announces intent to keep PFOA/PFOS MCLs while pursuing rulemaking to extend the PFAS NPDWR compliance timeline and reconsider other PFAS components

EPA announced (via news release) that it will retain the existing Maximum Contaminant Levels (MCLs) for PFOA and PFOS under the PFAS National Primary Drinking Water Regulation, but intends to provide additional time for compliance through a forthcoming rulemaking. The announcement also signals EPA’s intent to rescind and reconsider regulatory determinations for PFHxS, PFNA, HFPO-DA (GenX), and the Hazard Index mixture approach. Drinking water compliance teams should treat this as a forward-looking timeline/scope change that may affect implementation plans pending proposal/finalization.
