House Bill No. [insert 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 retailers about the restrictions at least one year prior to their implementation and are required to recall any non-compliant products. The bill also establishes penalties for violations, with fines escalating for repeated offenses. Overall, this legislation seeks to protect public health and the environment by limiting exposure to harmful chemicals in consumer products and firefighting materials.
