The American Chemistry Council (ACC) strongly supports the rigorous, well-established scientific and administrative process Congress has designed for the regulation of chemicals management in the United States. We are deeply concerned with language in and amendments to H.R. 7900, the National Defense Authorization Act for Fiscal Year 2023, that would circumvent the ongoing regulatory process for per- and polyfluoroalkyl substances (PFAS), restrict procurement of certain PFAS-containing products, threaten the supply chain for critical products and technologies, impose restrictions on disposal that will hinder cleanup, and dramatically escalate the cleanup costs for the Department of Defense (DoD) at eligible sites.
