Vehicular air pollution: regulations: exemption.

Existing law imposes various limitations on the emissions of air contaminants for the control of air pollution from vehicular and nonvehicular sources. Pursuant to that authority, the State Air Resources Board has adopted a regulation to significantly reduce emissions of particulate matter, oxides of nitrogen, and other criteria air pollutants from existing diesel trucks and buses operating in the state, commonly known as the Truck and Bus Regulation. This bill would require the state board to exempt vehicles that do not exceed 5,000 miles annually and low-mileage agricultural vehicles, as defined, that meet certain requirements from any regulation to reduce emissions of diesel particulate matter, oxides of nitrogen, and other criteria air pollutants from in-use, diesel-fueled vehicles.
