The City of Santa Ana, Calif., with the help of $55,000 in funding from the Mobile Source Air Pollution Reduction Review Committee (MSRC) Local Government Match Program, has recently completed the installation of emission control devices - diesel particulate filters (DPFs) - on six of its heavy-duty diesel vehicles. The retrofitting project is a continuation of the efforts of the MSRC and the City to improve air quality in the region through clean transportation initiatives, according to a release.
The six heavy-duty diesel vehicles, including water, cement, and dump trucks are essential for daily operations in the community. After careful consideration, it was determined that replacing the trucks with alternative vehicles would not be a practical option for the City. In order to reduce harmful toxins from the trucks’ exhaust, after-treatment devices verified to California Air Resources Board (CARB) Level 3 were installed on the trucks. Level 3 technology achieves an 85% reduction in particulate matter. Using this conventional strategy, Santa Ana is reducing emissions and purifying the air.
