EPA Proposed Recission of Regulatory Determinations and Removal of Related Provisions for Four PFAS Substances

Deadline: July 20, 2026

The proposed rule to Rescind Regulatory Determinations and Regulations for PFHxS, PFNA, HFPO-DA, and Hazard Index Mixtures corrects the Biden Administration’s failure to follow the clear requirements of the Safe Drinking Water Act (SDWA) in promulgating regulations for perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide dimer acid and its ammonium salt (HFPO-DA) (commonly knows and GenX chemicals), and Hazard Index mixtures of these three PFAS plus perfluorobutane sulfonic acid (PFBS). Following the proposed rule publishing in the Federal Register, the EPA will accept written comments on the proposed rule in the public docket for 60 days at www.regulations.gov under Docket ID: EPA-HQ-OW-2025-0654.
