California Sues EPA Over Emissions Rules Sent to Congress

California has filed a lawsuit against the U.S. Environmental Protection Agency (EPA) after the agency transmitted four state vehicle emissions rules to Congress for potential repeal. The EPA contends that waivers granted to California under the Clean Air Act, which allow the state to implement stricter emission standards than federal regulations, are subject to review under the Congressional Review Act (CRA).

The state argues that the EPA's action is illegal and seeks an injunction from the U.S. District Court in Washington to block the process. California's Air Resources Board Chair, Lauren Sanchez, stated that the state will not accept the federal administration's actions denying Californians the right to clean air.

The waivers in question pertain to vehicle emissions standards, including the Advanced Clean Cars I (ACC I) program, and rules for small offroad engines. These regulations have prompted a shift towards electric vehicles and stricter emission controls. The EPA, under Administrator Lee Zeldin, stated that transmitting these waivers fulfills a statutory obligation to Congress, ensuring its mandated review opportunity.

This action follows previous efforts by the Trump administration to limit California's authority on vehicle emissions and promote gasoline-powered vehicles. The Biden administration had previously reinstated the ACC I waiver after it was revoked. The lawsuit highlights the ongoing tension between California's environmental regulations and federal policy, particularly concerning vehicle emissions and the transition to electric vehicles.
