Creates new provisions regarding the discharge of foam fire suppressants

HB 1466 bans the sale and use of firefighting foam containing intentionally added PFAS (a type of harmful chemical) in Missouri, with limited exceptions for airport use (if federally required) and military applications. It requires manufacturers to report foam discharges within 24 hours, provide compliance certificates, and recall PFAS-containing foam before the 2027 ban takes effect. The law also directs the Department of Natural Resources to create rules protecting water and soil from PFAS contamination. This directly affects foam manufacturers, fire departments, airports, and military facilities using such foam.
