On July 26, 2007, the Air Resources Board (ARB) adopted a regulation to reduce diesel particulate matter (PM) and oxides of nitrogen (NOx) emissions from in-use (existing) off-road heavy-duty diesel vehicles in California. Such vehicles are used in construction, mining, and industrial operations. For more information you can call the diesel vehicle information hot line at (866) 6-DIESEL or (866) 634-3735.

Also, please see information on the ARB's program for new off-road mobile equipment instead of in-use PM control measures, or see information on ARB's program for off-road large spark-ignition equipment (e.g., forklifts).
