A joint resolution providing for 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 Pollution Control Standards; Notice of Decision Granting a Waiver of Clean Air Act Preemption for California's 2009 and Subsequent Model Year Greenhouse Gas Emission Standards for New Motor Vehicles".

This joint resolution aims to disapprove a specific rule issued by the Environmental Protection Agency (EPA) under the authority of chapter 8 of title 5, United States Code, which governs congressional review of agency rules. The EPA rule in question, published in 2009, granted California a waiver of Clean Air Act preemption , enabling the state to implement its own stricter greenhouse gas emission standards for new motor vehicles for the 2009 model year and all subsequent years. By enacting this resolution, Congress would invalidate the EPA's decision to grant this waiver, thereby removing California's authority to enforce these independent state-level emission standards. The resolution explicitly states that upon disapproval, the EPA rule would have no force or effect, effectively preventing California from setting its own distinct greenhouse gas emission regulations for vehicles and potentially impacting national automotive emission policies.
