Bill > SB509

This bill prevents the Oregon Environmental Quality Commission (EQC) from adopting and stops the Department of Environmental Quality (DEQ) from enforcing California-based motor vehicle emission standards that mandate zero-emission requirements for medium- and heavy-duty vehicles. Specifically, the bill prohibits the EQC from implementing California's standards that would require some or all new medium- or heavy-duty trucks sold in Oregon to be zero-emission vehicles, even though these standards could potentially be adopted under section 177 of the federal Clean Air Act. The bill further ensures that any such standards previously adopted by the commission cannot be enforced. This legislation effectively blocks Oregon from following California's progressive vehicle emission regulations aimed at reducing greenhouse gas emissions from commercial truck fleets, potentially protecting traditional vehicle manufacturers and trucking industries from more stringent environmental requirements.
