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 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".

SJRES 46 is a joint resolution seeking congressional disapproval of an Environmental Protection Agency (EPA) rule concerning California's vehicle emission standards. The rule, submitted in 2023, relates to California's pollution control requirements for motor vehicles, including advanced clean trucks, zero-emission airport shuttles, and heavy-duty engine emissions. This resolution would block the rule from taking effect using a specific federal disapproval process under Title 5 of the U.S. Code. If passed, the rule would have no legal force, meaning California's current standards would remain without the EPA's formal approval for these specific provisions.
