AB 1436: State Air Resources Board: air pollution regulations: private fleets: exception.

Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

Existing law requires the State Air Resources Board to adopt and implement motor vehicle emission standards, in-use performance standards, and motor vehicle fuel specifications for the control of air contaminants and sources of air pollution that the state board has found necessary, cost effective, and technologically feasible. The California Global Warming Solutions Act of 2006 establishes the state board as the state agency responsible for monitoring and regulating sources emitting greenhouse gases and requires the state board to adopt rules and regulations to achieve the maximum technologically feasible and cost-effective greenhouse gas emission reductions from those sources.

Pursuant to its authority, the state board has adopted the Advanced Clean Fleets Regulation, which imposes various requirements for transitioning local, state, and federal government fleets of medium- and heavy-duty trucks, other high-priority fleets of medium- and heavy-duty trucks, and drayage trucks to zero-emission vehicles.

Existing federal law, the Clean Air Act, prohibits any state or any political subdivision thereof from adopting or attempting to enforce any standard relating to the control of emissions from new motor vehicles or new motor vehicle engines, except through a waiver, as provided.

This bill would prohibit the state board from enforcing any regulation that directly or indirectly compels compliance by private fleets, as provided, until the state has obtained a required waiver or authorization under the federal Clean Air Act.
