On Wednesday, June 8, Illinois Governor JB Pritzker signed into law a first-in-the-nation policy that prohibits the disposal by incineration of PFAS (perfluoroalkyl and polyfluoroalkyl substances) that are listed in the U.S. Environmental Protection Agency’s Toxic Release Inventory. This includes, but is not strictly limited to, PFAS substances that are often found in aqueous film-forming foam, otherwise known as firefighting foam. In 2020, New York adopted a similar law that banned the incineration of PFAS-containing firefighting foams at a specific facility, but Illinois is the first to issue a statewide ban on incinerating certain PFAS.
