3. ON-ROAD REGULATION Title 13 CCR 2020-2022.1 Adopted December 8, 2005 to reduce Diesel engine Particulate Matter exhausted into the air. Final mandate January 2007 Applicable to Municipalities and Utilities who own, lease, or operate in California. Applicable to On-Road diesel-fueled heavy-duty vehicles >14,000 lb GVWR, 1960-2006 model year. Must bring engines into compliance with clean engine standards according to specified schedule Must use “Best Available Control Technology” (BACT) to retrofit exhaust. If cannot retrofit, then must be retired, replaced or repowered

4. CLEAN ENGINE STANDARDS 1. Engine is certified to a diesel particulate emission standard of 0.01 grams/brake horse power hour (g/bhp-hr). If not, then: 2. Engine is certified to a diesel particulate emission standard of 0.1 g/bhp-hr, and is equipped the most effective diesel particulate control device, or uses an alternative fuel certified to reduce diesel particulates; if not, then: 3. Engine uses an alternative fuel; if not, then; 4. Engine uses most effective diesel emission control certified for the Engine.
