PROTECT Act of 2021

Introduced October 19, 2021

AI-Generated Summary

Updated February 8, 2026 at 7:23 AM UTC

The PROTECT Act of 2021 adds several per‑ and polyfluoroalkyl substances (PFAS)—including perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorobutanesulfonic acid (PFBS), and GenX chemicals—to the list of hazardous air pollutants under the Clean Air Act. It requires the EPA to revise source‑category rules within two years and finalize emission standards within five years, and to consider additional PFAS for future listing. The law also directs the agency to improve measurement and testing methods for these chemicals.

Key Provisions

  • Lists PFOA, PFOS, PFBS, and GenX chemicals as hazardous air pollutants.
  • EPA must revise major and area source categories to cover these substances within 2 years of enactment.
  • EPA must finalize emission standards and related regulations for the listed PFAS within 5 years.
  • Within 5 years, EPA must decide whether to add other PFAS to the hazardous pollutant list and follow similar timelines for source categories and standards.
  • Agency must support research and develop methods to measure and report emissions of the listed substances.
  • Petition review timelines under the Clean Air Act remain unchanged.
