Santa Rosa Diesel Smoke Opacity Testing
Diesel Smoke Opacity Testing in Santa Rosa, California
All heavy-duty diesel-powered vehicles that are 14,000 lbs. gross vehicle weight rating (GVWR) or greater in fleets of two or more (except those equipped with engines that are four years old or less and those vehicles used exclusively for personal use, such as motor homes), must be tested annually (on or before December 31 of each year) with a smoke opacity meter according to the SAE J1667 specifications and test procedures. All heavy-duty diesel-powered vehicles must meet the applicable opacity standards of 55% for pre-1991 engines and 40% for 1991 and newer engines. All heavy-duty diesel-powered vehicles determined to be in non-compliance must be promptly repaired and brought into compliance.
