Associations file opening brief in PFAS case

On Oct. 7, the American Water Works Association (AWWA) and the Association of Metropolitan Water Agencies (AMWA) filed the organizations’ opening brief with the United States Court of Appeals in the case of AWWA vs. U.S. Environmental Protection Agency (EPA), related to EPA’s final drinking water regulation for six per- and polyfluoroalkyl substances (PFAS), known as the National Primary Drinking Water Regulation (NPDWR).

Oct. 7 was the court-imposed deadline AMWA and AWWA had to submit their initial brief that will carry the bulk of the organizations’ arguments against the rule. In addition to the 13,000-word AMWA/AWWA brief, a group of chemical sector organizations plan to file a separate 13,000-word brief with the court detailing their own concerns with the NPDWR.
