This joint resolution aims to disapprove a rule submitted by the Environmental Protection Agency (EPA) under the Congressional Review Act. The EPA rule in question granted a waiver of Clean Air Act preemption for California's Advanced Clean Car Program and provided a "within the scope" confirmation for California's Zero Emission Vehicle Amendments for 2017 and earlier model years. Should this resolution be enacted, the specified EPA rule would be declared to have no force or effect. This action would effectively revoke the federal approval that allows California to implement its more stringent motor vehicle pollution control standards, potentially impacting the state's authority to set its own emission regulations.
