On September 4, the U.S. Environmental Protection Agency (EPA) (finally) published its Spring 2025 Unified Agenda of Regulatory and Deregulatory Actions (UA), a semiannual publication outlining federal agencies’ regulatory priorities and timelines for the upcoming year. The UA included a notice of its intent to rescind drinking water limits set by a Biden-era rule for three per- and polyfluoroalkyl (PFAS) substances and one PFAS mixture. EPA also published a notice of intent to retain limits on PFOA and PFOS, although with extended timelines for compliance.
