California retains strict clean air waivers after federal judge blocks EPA action

A federal judge has granted a preliminary injunction blocking the Environmental Protection Agency (EPA) from targeting four Clean Air Act preemption waivers previously granted to California. The ruling by U.S. District Judge Beryl Howell orders the EPA to “restore the status quo” regarding these waivers, which allow California to implement stricter emissions standards for vehicles, including passenger cars and light-duty trucks, than the federal government.

The legal dispute arose after the Trump administration and the EPA sought to reclassify these waivers as rules subject to congressional repeal under the Congressional Review Act. California officials, including Attorney General Rob Bonta and Governor Gavin Newsom, filed a lawsuit alleging the move was an “unlawful attempt to circumvent administrative procedure.” While the injunction provides a temporary victory for California’s ability to set independent environmental standards, the EPA is reportedly considering options for an appeal.
