Senate votes to overturn EPA rule that limits 7 hazardous air pollutants

The Senate on Thursday approved an effort to overturn an Environmental Protection Agency rule tied to the Clean Air Act and designed to limit seven of the most hazardous air pollutants that are emitted by heavy industry.

The 52-46 party-line vote marked the first time in the 55-year history of the Clean Air Act that Congress has moved to weaken the power of the landmark environmental law.

Senate Republicans utilized the Congressional Review Act to overturn the regulation, which was passed by the Biden administration in 2024.
