Creates new provisions regarding the discharge of foam fire suppressants

HB 2270 prohibits the manufacture, sale, or distribution of firefighting foam containing intentionally added PFAS (perfluoroalkyl substances) in Missouri after January 1, 2028, with limited exceptions for airport use (if federally required) and military applications. It requires manufacturers to notify recipients and recall PFAS-containing foam sold before the ban, and mandates immediate reporting of any discharge of such foam to the Department of Natural Resources within 24 hours. The bill directly affects foam manufacturers, fire departments, airports, and military facilities that use or distribute these products. Key provisions include new environmental regulations for PFAS-containing foam and a transition period for manufacturers to phase out sales. The law aims to protect Missouri's water and soil from PFAS contamination by restricting the use of these persistent chemicals.
