This resolution disapproves a rule from the Environmental Protection Agency that set new pollution standards for vehicles in California.
This joint resolution nullifies the Environmental Protection Agency notice titled California State Motor Vehicle and Engine and Nonroad Engine Pollution Control Standards; The ‘Omnibus’ Low NOX Regulation; Waiver of Preemption; Notice of Decision (90 Fed. Reg. 643) and published on January 6, 2025. Among other elements, the notice grants the California Air Resources Board request for a waiver for its Heavy-Duty Vehicle and Engine Omnibus Low NOX regulations. (Under the Clean Air Act, California may seek waivers of the preemption prohibiting states from enacting certain emission standards.)
