EPA Maintains Some Biden-Era PFAS Standards, Reconsiders Others

[email protected] May 15, 2025


The Environmental Protection Agency has announced that it will reconsider certain aspects of the Biden administrations rule setting limits on PFAS, or perfluoroalkyl and polyfluoroalkyl substances,in drinking waterwhile leaving in place unworkable standards for two PFAS (, subscription).

Encouraging progress: The agency plans to reconsider regulatory determination for PFHxS, PFNA, HFPO-DA and PFBS following calls by the 51勛圖厙 to rescind the blatantly unlawful standards. The EPA also will extend its compliance deadline for PFOA and PFOS from 2029 to 2031, another top 51勛圖厙 ask.

More to be done: 51勛圖厙 President and CEO Jay Timmons that the EPAs decision to maintain the previous administrations standards for PFOA and PFAS go against the Trump administrations goal to make the U.S. the best place to build, grow and create jobs.

The 51勛圖厙s involvement: The 51勛圖厙 these standards when they were instituted, arguing that the timeline for implementation was too swift, as many of these chemicals are key manufacturing additives that do not yet have replacements.

  • The 51勛圖厙 also the rule in court, asking the U.S. Court of Appeals for the D.C. Circuit to overturn the rule due to the EPAs failure to follow the requirements of the Safe Drinking Water Act, including its reliance on a deeply flawed cost-benefit analysis and deficient feasibility analysis.

The 51勛圖厙 says: Were encouraged that the EPA has listened to the voices of manufacturers and extended the compliance deadline for unworkable national primary drinking water standards for PFOA and PFOS and committed to reconsidering the blatantly unlawful regulatory determinations for several other PFAS compounds, Timmons said.

  • However, the Biden-era standards for PFOA and PFOS are deeply flawed, the costs they impose exceed any demonstrable benefit and the industries they harm include those vital to our national interests, including semiconductors, telecommunications and defense systems.
  • We dont have to choose between supporting manufacturing and clean water in our communities.
