Bill > SB5091

This bill addresses motor vehicle emission standards in Washington state, focusing on maintaining alignment with federal clean air standards while avoiding the adoption of California's specific emission standards. The legislation recognizes the importance of decarbonizing the transportation sector but seeks a more flexible approach tailored to Washington's unique economic needs. Specifically, the bill directs the Department of Ecology to adopt motor vehicle emission rules that remain consistent with the federal Clean Air Act, explicitly prohibiting the state from adopting California's alternative emission standards. The bill makes several technical amendments to existing laws, including modifying registration requirements, updating references to emission standards, and repealing previous statutes related to California motor vehicle emission standards. Key changes include exempting certain vehicle types from emission testing, updating language around vehicle registration and licensing, and ensuring that air conditioning equipment meets safety and environmental standards. The overall intent is to provide Washington with more regulatory flexibility in addressing vehicle emissions while still maintaining environmental protections.
