Deadline to comment on EPA proposal to extend PFOA and PFOS compliance deadline for 2 years
July 20 @ 9:30 pm - 9:59 pm
The EPA proposed Docket ID EPA-HQ-OW-2025-1742 to extend the PFOA and PFOS compliance deadline from April 26, 2029, to April 26, 2031. Qualifying water systems unable to meet the 4.0 parts per trillion (PPT) maximum contaminant levels (MCLs) can apply for this two-year federal extension to complete infrastructure upgrades. [1, 2, 3]
Key Details of the Proposal
- The Rule: The enforceable limits themselves remain unchanged, but qualifying public water systems can request the delay to install necessary treatment technologies. [1]
- Application Process: Systems granted an extension must demonstrate why they cannot meet the 2029 deadline and are required to notify the public of their updated timeline. [1]
- Deadline: The public comment period for this rule closes on July 20, 2026. [1]
