HR-6990-119
Referred to the House Committee on Energy and Commerce.
Sponsored by Haley Stevens (D-MI)
What it does
The bill would require the EPA Administrator to issue a final rule, within 180 days of enactment, adding all perfluoroalkyl and polyfluoroalkyl substances (PFAS) with at least one fully fluorinated carbon atom, as a class, to the Clean Air Act's hazardous air pollutant list. Within 365 days after that rule, the Administrator would have to revise the source category list to include major and area sources of the listed PFAS. Listing would trigger the Clean Air Act's existing emission-standard process for those source categories.
Who benefits
Residents near facilities that emit PFAS, who could see lower airborne exposure if emission standards follow. Public water utilities and downstream communities, since airborne PFAS can settle into water and soil. Public health researchers and regulators, who would gain a uniform class-wide listing instead of substance-by-substance reviews. Firms that make PFAS-free alternatives could also gain demand.
Who is hurt
Manufacturers, chemical producers, semiconductor makers, and other industrial facilities that emit PFAS, which could face new permitting, monitoring, and control-technology costs. Consumers may pay higher prices if costs are passed along. Small area-source operators could face compliance burdens. EPA would face a tight statutory deadline and a large workload, and state air agencies could bear added implementation duties.
Supporters argue
Supporters argue that PFAS persist in the environment and the body, and that airborne emissions spread contamination to water, soil, and food. They contend that listing the whole class, rather than individual chemicals one at a time, matches the way these substances behave and gives regulators a workable tool. Congress setting a fixed deadline, they argue, avoids delay and gives the agency clear authority.
Opponents argue
Opponents argue that the class covers thousands of substances with widely varying toxicity, and that the Clean Air Act's listing process normally relies on agency scientific review of each pollutant's health effects. They contend that a 180-day statutory deadline skips that review and could impose large compliance costs on many industries without evidence tied to specific compounds. Setting standards for so broad a class, they argue, may prove unworkable.
Constitutional context
Congress may regulate air pollution from commercial and industrial activity under the Commerce Clause (Art. I, §8, cl. 3), as reflected in the Clean Air Act. Because Congress itself directs the listing, the bill largely sidesteps major questions concerns under West Virginia v. EPA (2022), though later rules implementing it would still face independent judicial review under Loper Bright v. Raimondo (2024).
Checks and balances
Congress would direct the EPA to act, narrowing agency discretion over whether and when to list; courts can review the resulting rules, and the Clean Air Act's judicial review and comment processes would still apply to later emission standards.
Historical precedent
Congress listed the original 189 hazardous air pollutants directly in the 1990 Clean Air Act Amendments, and has at times directed EPA action by statute, as with the 2020 NDAA's PFAS provisions.
