EPA proposes federal exemption framework to extend PFOA/PFOS MCL compliance deadline from April 26, 2029 to April 26, 2031

EPA announced a proposed rule that would create a federal exemption framework allowing eligible public water systems to request an optional two-year extension to comply with the PFOA and PFOS Maximum Contaminant Levels (MCLs), shifting the compliance date from April 26, 2029 to April 26, 2031. EPA indicates the proposal would not change the numeric MCL values. The proposal includes a 60-day public comment period following Federal Register publication and a virtual public hearing on July 7, 2026. Water utilities and compliance teams should assess eligibility and potential planning impacts, and consider submitting comments.
