EPA Partially Rolls Back 'Forever Chemical' Regulations
The Environmental Protection Agency has announced a partial rollback of limits on per- and polyfluoroalkyl substances (PFAS), also known as 'forever chemicals,' which are used in many manufacturing processes. While the move may provide some compliance cost relief, it is expected to face legal challenges from environmental groups and several states, creating a complex and shifting federal-versus-state compliance landscape for manufacturers.
- The rollback specifically targets a 2024 rule by rescinding the Maximum Contaminant Levels (MCLs) for four PFAS compounds: PFHxS, PFNA, PFBS, and HFPO-DA (commonly known as GenX). For two other well-known compounds, PFOA and PFOS, the rule extends the compliance deadline for public water systems by two years, from 2029 to 2031. - The National Association of Manufacturers (NAM) applauded the decision, stating they were "encouraged that the EPA has listened to the voices of manufacturers." NAM had previously challenged the regulations in court, arguing the standards were "unworkable," relied on a flawed cost-benefit analysis, and would harm vital industries like semiconductors and defense that rely on these chemicals. - This move is expected to face legal challenges based on the Safe Drinking Water Act's "anti-backsliding" provision, which generally prohibits the EPA from weakening existing drinking water protections. Environmental and public health groups have already initiated lawsuits against the EPA for other recent regulatory repeals. - The federal shift contrasts with aggressive state-level actions, where at least 36 states have introduced bills to regulate PFAS. Many states have already established their own drinking water limits, creating a complex and inconsistent "patchwork" of regulations for manufacturers to navigate, with some state standards being stricter than the now-rescinded federal ones. - These chemicals are widely used in manufacturing for their resistance to heat, water, and oil. Key applications include semiconductor manufacturing, aerospace and automotive components, high-performance textiles, and medical devices, where viable alternatives are not always available. - The European Union is moving in the opposite direction, with a proposal from five member nations to enact a blanket ban on the manufacturing, marketing, and use of all PFAS chemicals. This divergence creates further complexity for global manufacturers navigating international compliance. - The EPA's next step involves a formal rulemaking process, with a proposed rule expected in the fall of 2025 and a final rule in the spring of 2026. The agency has also filed a motion in federal court to vacate the standards for the four targeted PFAS chemicals as part of ongoing litigation.
