Dive Brief:
The U.S. EPA has proposed a new rule that would formally rescind Safe Drinking Water Act regulations for four types of PFAS that were set under the Biden Administration. The EPA first announced its intention to roll back the regulations a year ago.
The rule would rescind limits for four types of per- and polyfluoroalkyl substances in the drinking water regulations: PFHxS, PFNA, PFBS and HFPO-DA, commonly known as GenX. The agency plans to continue regulating PFOA and PFOS, but will delay enforcement to 2029.
EPA also announced a proposed rule that would allow certain eligible water utilites to apply for a two-year compliance delay on meeting drinking water standards for PFOS and PFOA, giving them until 2031 if they meet certain requirements.
