Emission standards: marine vessels: exemption.

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 to be necessary, cost effective, and technologically feasible, as provided. Existing law also requires the state board to adopt standards and regulations, consistent with those requirements, for motor vehicles and off-road or nonvehicle engine categories, including, but not limited to, marine vessels, to the extent permitted by federal law. This bill would require the state board to exempt certain vessels from any provision of a standard or regulation that would require the retirement, replacement, or retrofit of the vessel. The bill would provide that the vessel would be exempt for a period not to exceed 15 years or until the cost to replace the vessel's internal combustion engine with a safe and reliable electric motor meets a specified threshold.
