Providing congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "California State Motor Vehicle and Engine Pollution Control Standards; Heavy-Duty Vehicle and Engine Emission Warranty and Maintenance Provisions; Advanced Clean Trucks; Zero Emission Airport Shuttle; Zero-Emission Power Train Certification; Waiver of Preemption; Notice of Decision".

This joint resolution uses the Congressional Review Act to disapprove an EPA notice (88 Fed. Reg. 20688, published April 6, 2023) that had granted California a waiver of federal preemption under the Clean Air Act. That waiver allowed California to enforce its own heavy-duty vehicle and engine emission warranty and maintenance provisions, its Advanced Clean Trucks rule, Zero Emission Airport Shuttle requirements, and Zero-Emission Power Train Certification standards. Because Congress disapproved the rule, it now has no force or effect. The resolution does not itself create new emissions standards or amend the Clean Air Act's waiver provisions; it simply revokes the specific EPA waiver decision, reverting the regulatory status of those California standards to their pre-waiver condition. It became law on June 12, 2025, as Public Law 119-15.

The California Air Resources Board, truck and engine manufacturers that sell vehicles in California and states that adopt California's standards, fleet operators of heavy-duty trucks and airport shuttles, and the Environmental Protection Agency, which issued the now-nullified waiver.

Manufacturers no longer face California's Advanced Clean Trucks and related zero-emission requirements as an enforceable state standard, potentially easing compliance burdens but also removing a driver of stricter emissions rules that other states often mirrored, affecting national heavy-duty vehicle emissions policy.
