HB 1649-FN is a New Hampshire bill that seeks to regulate the use of per and polyfluoroalkyl substances (PFAS) in a variety of consumer products, including adult mattresses, carpets, cosmetics, feminine hygiene products, food packaging, juvenile products, personal protective equipment, upholstered furniture, textiles, and textile furnishings. The bill defines PFAS and sets forth what constitutes "intentionally added PFAS." It exempts certain products from the restrictions, such as those manufactured before the ban's effective date and products where federal law preempts state authority. The bill also includes appropriations for the Department of Environmental Services to fund an additional position and the PFAS products control program. Notably, the bill does not contain or tags, indicating it is not amending existing law but introducing new legislation. The bill mandates that manufacturers or suppliers provide a certificate of compliance to the Department of Environmental Services upon request, confirming that a product meets the requirements or qualifies for an exemption. It establishes a full-time environmentalist IV position within the Department of Environmental Services to oversee the implementation of the bill, including rulemaking, coordination, compliance assurance, and enforcement. The bill appropriates $250,000 for the biennium ending June 30, 2025, for administrative costs and establishes the effective date of the act as upon its passage. The fiscal note attached to the bill indicates that while it does not impact state revenue, it does increase state expenditures, and provides a detailed cost estimate for the new environmentalist position and associated program costs.
