PFAS Hazardous Air Pollutants Listing

Summary#

This bill tells the Environmental Protection Agency (EPA) to add nearly all perfluoroalkyl and polyfluoroalkyl substances (PFAS) that contain at least one fully fluorinated carbon atom to the federal list of hazardous air pollutants. It also requires EPA to update the list of source categories that emit those substances. The stated policy goal is to identify PFAS in air pollution law so EPA and others can address their releases.

  • Main change: EPA must issue a final rule within 180 days adding PFAS (with at least one fully fluorinated carbon) as a class to the Clean Air Act’s hazardous air pollutants list.
  • Follow-up: Within 365 days after that final rule, EPA must revise the list of major and area source categories that emit those PFAS.
  • Goal: The bill aims to bring PFAS under the Clean Air Act’s hazardous air pollutant framework so sources and emissions can be identified and addressed.

What it means for you#

  • Communities near industrial sites: This could lead to new EPA actions to identify and control air emissions of PFAS from nearby facilities.
  • Facilities that make, use, or emit PFAS: Businesses that emit PFAS to the air would be placed into named source categories once EPA revises the source list. This could lead to future limits, monitoring, or permit changes (the bill itself does not set specific limits).
  • EPA and state air agencies: EPA must complete two rulemaking steps on a set schedule (180 days and then 365 days). State agencies that implement federal air rules may need to adjust staff, permits, or enforcement plans later.
  • Employees and contractors at regulated sites: Over time, workplaces that handle PFAS may face new compliance steps if EPA issues standards for emissions or monitoring.
  • General public: The bill does not immediately change taxes, benefits, or direct payments to individuals. Practical effects depend on the rules EPA issues after listing the substances and source categories.

Expenses#

No publicly available information.

Possible costs that could follow (based on what the bill requires and typical rulemaking outcomes):

  • Federal administrative costs: EPA will need staff time and resources to complete the two rulemakings on the required timetable.
  • State and local costs: State air agencies that implement or enforce any later EPA standards could face staff and administrative costs.
  • Business compliance costs: Companies in newly listed source categories could face costs for monitoring equipment, pollution controls, reporting, permitting, or process changes if EPA later issues emission standards.
  • Legal and implementation costs: Short timelines or broad class listings could lead to legal challenges or complex technical work to identify which substances and sources are covered.

Proponents' View#

  • The bill appears intended to ensure PFAS that meet the chemical definition are treated as hazardous air pollutants under the Clean Air Act.
  • Supporters may argue this would make it easier for EPA to identify and target air emissions of PFAS.
  • Placing PFAS in a class could streamline regulation of many related chemicals at once instead of addressing them one-by-one.
  • The deadlines in the bill aim to force timely action by EPA to address PFAS in air emissions.

Opponents' View#

  • One concern is the short timetable (180 days and then 365 days) may not give EPA enough time to complete a technically accurate and legally robust rulemaking for a large class of chemicals.
  • The bill does not specify what emission limits, controls, or monitoring will apply; opponents could say that leaves major costs and details for later rulemaking.
  • Listing an entire class of chemicals that may have widely varying uses and properties may raise questions about how to define coverage and apply controls fairly.
  • Businesses and states may face uncertain future compliance costs because the bill requires listing and source-category updates but not the specific regulatory steps or cost estimates.
  • It is unclear how the bill would interact with other federal or state PFAS actions, or what enforcement approach would be used.
