The Authority
(by Michael Korns and Amanda Brosy)
Municipal authorities and other public entities in Pennsylvania have long been familiar with the weight and burden of DEP and EPA mandates and regulations. Whether it involves issues with stormwater infiltration, erosion and sediment control, or any number of issues related to water treatment, all too often authorities must correct issues that they did not cause. Given that history, authorities should brace themselves, because new regulations will put them in the crosshairs again.
PFAS – A pollutant that means forever.
The new issue facing authorities relates to a large group of man-made chemicals known as per- and polyfluoroalkyl substances, or “PFAS” for short. PFAS are resistant to heat, oils, stains, and water, and for that reason, PFAS have been incorporated into a wide variety of consumer products and industrial processes since the 1940s. They are ubiquitous in the environment and are known as “forever chemicals” because they do not readily break down in nature. Ongoing research shows a variety of potential health risks related to PFAS exposures.
Pennsylvania has adopted PFAS standards related to drinking water and environmental cleanup, and EPA, which is working to address PFAS pollution on multiple regulatory fronts, recently finalized the first-ever national drinking water standard related to PFAS. In December 2023, DEP also updated its NPDES Individual Industrial Wastewater permit application to include PFAS sampling. Applications going forward are required to include sampling for four PFAS: PFOA, PFOS, PFBS, and HFPO-DA (commonly referred to as GenX) as part of Pollutant Group 1 sampling. Because sampling is required under Pollutant Group 1, all industrial categories are subject to the sampling requirements.
The heart of the issue for authorities is this: the elimination of PFAS in drinking water is a regulatory priority for both EPA and DEP. …
