The City of Los Angeles, Department of Public Works, purchased 42 new solid waste collection vehicles. The vehicles use the Peterbilt 320 chassis and the Amrep solid waste collection body and are equipped with the Caterpillar C-10, 10.3 liter pilot ignition liquefied natural gas (LNG) engine. This engine operates primarily on liquefied natural gas, but initiates the natural gas fuel ignition using a diesel fuel "pilot" charge. In essence, the diesel pilot acts as a liquid spark plug to ignite the primary natural gas fuel charge. The LNG fuel system is supplied by Chart Idustries. In addition to the purchase of alternative fuel vehicles, the City of Los Angeles constructed a LNG refueling station. The MSRC contributed $100,000 as co-funding towards the LNG station construction.

The residents of the City of Los Angeles are the principal beneficiaries of the use of clean fuel residential refuse collection vehicles; however, all areas of the South Coast AQMD benefit from the reduction in ozone precursor emissions.
Annual emission reduction estimates attributable to the 42 LNG trucks are as follows: Oxides of Nitrogen (NOx): 6.08 tons per year Particulate Matter (PM10): 0/168 ton per year
The Final Report includes a Project Description, Discussion, Emission Benefits Assessment, Summary and Conclusions, and Recommendations.
