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 resolution cancels an Environmental Protection Agency rule that let California enforce its own stricter pollution rules for heavy-duty trucks and other large vehicles, including a program requiring bigger fleets to phase in zero-emission trucks (called Advanced Clean Trucks) and matching emission-warranty and maintenance requirements. The rule had relied on a special legal waiver that lets California set vehicle standards tougher than federal ones, with other states allowed to follow California's lead. Congress is using its authority under the Congressional Review Act to void this rule entirely, meaning it will have no legal effect going forward. This affects trucking companies, fleet operators, and any state that had adopted California's stricter truck-emission standards. The practical result is that California and copycat states lose the ability to require cleaner heavy-duty trucks under this specific program.
