State Air Resources Board: compliance: regulations.

Existing law imposes various limitations on the emissions of air contaminants for the control of air pollution from vehicular and nonvehicular sources. 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, until January 1, 2023, to deem a person, as defined, to be in compliance with the Truck and Bus Regulation and would prohibit the state board from requiring a person to expend further moneys to achieve compliance with, or from seeking to enforce against that person, that regulation if specified conditions are met.
