Environment (Drinking Water)

This bill (LD 1982) updates Maine's legal definition of "PFAS" to match the U.S. Environmental Protection Agency's technical definition. It amends two key statutes (32 MRSA §1732 and 38 MRSA §1614) to align the state's definition with the EPA's standard for fluorinated chemicals containing specific molecular structures. This change ensures uniformity across multiple environmental regulations, including those governing toxics in packaging, PFAS-containing products, firefighting foam, waste discharges, and contamination cleanup funds. The bill does not create new restrictions but standardizes existing regulatory language to reflect federal definitions.

LD 1903 aligns Maine's regulations for perfluoroalkyl and polyfluoroalkyl substances (PFAS) with federal standards set by the U.S. Environmental Protection Agency. It establishes specific soil concentration limits for PFAS contamination (based on EPA guidance) and requires Maine's drinking water rules to adopt the EPA's 2024 maximum contaminant levels for six specific PFAS chemicals, including PFOA and PFOS. The bill also revises restrictions on PFAS in food packaging, mandating that state bans require proof a safer alternative is available and acknowledging federal regulations may preempt state rules. These changes directly affect Maine's environmental cleanup efforts, public water systems, and food packaging manufacturers.
