The U.S. Environmental Protection Agency (EPA) released a memorandum to states yesterday that provides direction on how to use the nation’s clean water permitting program to protect against per- and polyfluoroalkyl substances (PFAS). The guidance outlines how states can monitor for PFAS discharges and take steps to reduce them where they are detected.
EPA says the new directions align wastewater and stormwater NPDES permits and pretreatment program implementation activities with the goals in EPA’s PFAS Strategic Roadmap.
“EPA is following through on its commitment to empower states and communities across the nation to address known or suspected discharges of PFAS,” said EPA Assistant Administrator for Water Radhika Fox. “Today’s action builds upon successful and innovative efforts already used by several states to safeguard communities by using our Clean Water Act permitting program to identify and reduce sources of PFAS pollution before they enter our waters.”
The memo recommends that states use the most current sampling and analysis methods in their NPDES programs to identify known or suspected sources of PFAS and to take actions using their pretreatment and permitting authorities, such as imposing technology-based limits on sources of PFAS discharges.
The full text of the memo can be found at Addressing PFAS Discharges in National Pollutant Discharge Elimination System (NPDES) Permits and Through the Pretreatment Program and Monitoring Programs.
