What: On April 17, 2025, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register extending the comment period for the Draft Sewage Sludge Risk Assessment for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS).
Why: The risk assessment provides information on risk from the use or disposal of sewage sludge and will inform the EPA’s potential future regulatory actions under the Clean Water Act.
The document analyzes the potential risks to human health and the environment posed by the presence of PFOA and PFOS in sewage sludge that is applied as a soil conditioner or fertilizer, surface disposed or incinerated. Risks are analyzed for individuals living on or near impacted sites or those who rely primarily on their products (e.g., food crops, animal products, and drinking water).
Action: Comments on the draft risk assessment are due August 14, 2025.
