EPA Moving Forward PFAS Regs and UCMR5

On February 22, 2021 EPA issued a Press Release indicating that the Agency is moving forward with two drinking water regulations involving PFAS.  The Press Release reads in part:

“EPA is reproposing the Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) to collect new data on PFAS in drinking water and the agency is reissuing final regulatory determinations for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) under the Safe Drinking Water Act (SDWA).  After a thorough review in accordance with Biden-Harris administration executive orders and other directives, the agency is reissuing these actions.“

“With the final Regulatory Determinations for PFOA and PFOS, EPA will move forward to implement the national primary drinking water regulation development process for these two PFAS. The Regulatory Determinations also outline avenues that the agency is considering to further evaluate additional PFAS chemicals and provide flexibility for the agency to consider groups of PFAS as supported by the best available science.”

“Additionally, the proposed UCMR 5 would provide new data that is critically needed to improve EPA’s understanding of the frequency that 29 PFAS are found in the nation’s drinking water systems and at what levels. EPA will accept public comment on the proposed UCMR 5 for 60 days, following publication in the Federal Register. EPA will also hold a virtual stakeholder meeting twice during the public comment period.”
