EPA announces it will keep PFOA/PFOS MCLs but intends to extend compliance timeline to 2031 and reconsider other PFAS components

EPA announced its intent to pursue SDWA rulemaking to extend the compliance deadline for the PFAS NPDWR MCLs for PFOA and PFOS to 2031 while keeping the existing MCL values. EPA also stated its intent to rescind and reconsider portions of the drinking water rule affecting PFHxS, PFNA, HFPO-DA (GenX), and the Hazard Index mixture approach (including PFBS). Compliance teams for public water systems and impacted upstream industries should monitor the forthcoming proposal/final action and evaluate how a potential compliance-date shift and scope changes would affect monitoring, treatment, and customer communications.
