SACRAMENTO– This Thursday the California Air Resources Board (ARB) will consider a plan to reduce statewide diesel emissions by 90 percent within the next ten years. If adopted, the plan calls for a dozen separate control measures that would require the use of low-polluting fuel, retrofits on existing engines and modifications on new engines to reduce emissions. The plan includes proposals that address both motor vehicles and stationary source engines.

Diesel particulate matter (PM) emissions have been found to be the most pervasive toxic air contaminant (TAC) in California, contributing about 70 percent of the health risk attributed to airborne toxic emissions.

In 1998 the Board identified diesel PM as a toxic air contaminant. Once a substance is identified as a TAC, the ARB is required by law to determine if there is a need for further control. If additional controls are deemed necessary, the Board must develop a risk management plan to protect public health.
