House Bill No. [insert bill number] aims to regulate the sale and use of products containing perfluoroalkyl and polyfluoroalkyl substances (PFAS) in Montana. The bill prohibits the manufacture, sale, or offering for sale of certain products, including cosmetics, juvenile products, and menstrual products that contain intentionally added PFAS, effective January 1, 2028. Manufacturers are required to provide a certificate of compliance to retailers, ensuring that their products do not contain these substances. Additionally, the bill outlines definitions for various terms related to the products affected, including "covered product," "manufacturer," and "intentionally added PFAS."

Furthermore, the bill addresses the use of class B firefighting foam and turnout gear containing PFAS, prohibiting their discharge or use for training purposes after January 1, 2028, unless specific conditions are met. Manufacturers must notify sellers about the restrictions at least one year prior to the effective date, and any non-compliance may result in civil penalties. The bill also mandates that manufacturers of firefighting personal protective equipment provide written notice to purchasers if their products contain PFAS. Overall, the legislation seeks to mitigate the environmental and health impacts associated with PFAS in consumer products and firefighting materials.
