Emission control regulations: groundwater drilling: portable engines, off-road vehicles, and on-road vehicles.

Existing law imposes various limitations on emissions of air contaminants for the control of air pollution from vehicular and nonvehicular sources. Existing law generally designates the State Air Resources Board as the state agency with the primary responsibility for the control of vehicular air pollution. Existing law requires the state board to adopt and implement motor vehicle emission standards, in-use performance standards, and motor vehicle fuel specifications for the control of air contaminants, including standards for off-road and nonvehicle engine categories. This bill would prohibit the state board from imposing specified emission control requirements on portable engines, off-road vehicles, or on-road vehicles used by a person holding a C-57 or C-61 (D-21 subcategory) license issued by the Contractors' State License Board for water well drilling, reconstruction, or maintenance, or water pump installation, repair, or maintenance, until 5 years after the emergency declared by the Governor on February 27, 2009, relating to a statewide water drought, has been proclaimed terminated. The state board would be required to evaluate regulations adopted by the state board on or before December 31, 2009, imposing requirements on portable engines, off-road vehicles, and on-road vehicles, and amend those regulations where necessary, to minimize the adverse impacts of multiple regulations adopted by the state board on those regulated by the regulations. The state board would be prohibited from imposing reporting requirements for off-road diesel-fueled fleets until January 1, 2015, at the earliest.
