This joint resolution aims to exercise congressional disapproval under the Congressional Review Act, specifically targeting a rule promulgated by the Environmental Protection Agency (EPA) . The resolution seeks to declare that the identified EPA rule, which relates to California's motor vehicle and engine pollution control standards , shall have no force or effect. The EPA rule in question covers a broad range of provisions, including emission warranty and maintenance for heavy-duty vehicles, the Advanced Clean Trucks program, zero-emission airport shuttles, and zero-emission powertrain certification. Crucially, it also involves the EPA's decision to grant California a waiver of preemption , allowing the state to enforce its own stringent emission standards. By disapproving this rule, Congress would effectively prevent California from implementing these specific vehicle emission regulations under the federal waiver.
