This joint resolution would overturn an Environmental Protection Agency rule that sets pollution standards for synthetic organic chemical manufacturers and polymer and resin producers. The EPA rule, issued in May 2024, established new performance standards for emissions of hazardous air pollutants from these industries. If passed, this resolution would invalidate the EPA regulation entirely, preventing it from taking effect. The measure was introduced by Senator Kennedy and four other senators and uses the Congressional Review Act, which allows Congress to disapprove federal agency rules within a specific timeframe. The resolution targets regulations designed to reduce air pollution from major chemical manufacturing facilities across the United States.
