EPA finalized a rule that improves reporting on per- and polyfluoroalkyl substances (PFAS) to the Toxics Release Inventory (TRI) by eliminating an exemption that allowed facilities to avoid reporting information on PFAS when those chemicals were used in small concentrations. Often referred to as "forever chemicals," PFAS are used at low concentrations in many products, and as a result of removing this reporting exemption, covered industry sectors such as manufacturing, metal mining, and chemical manufacturing, as well as federal facilities that make or use any of the 189 TRI-listed PFAS, will no longer be able to avoid disclosing the quantities of PFAS they manage or release into the environment.
