This project involved the purchase of seven (7) CNG refuse collection trucks and the installation of a CNG slow-fill fueling station at the City of Hemet Corporation Yard. The goal of the project was to reduce emissions and reduce operating costs associated with driving CNG vehicles to a fast-fill CNG station at another agency. Since fast-fill stations do not completely fill the fuel tank, drivers were often required to return to the station for more fuel in order to finish their route.

All seven CNG refuse collection vehicles were placed into service by December 1, 2007. In December 2011, the City sold its refuse operation, vehicles and other related equipment to CR&R Waste Services. CR&R agreed to continue operating these seven vehicles in the SCAQMD to meet the geographical restriction requirements (85% of annual mileage within SCAQMD for a period of 5 years) of the funding contract. This 5 year period ended in December 2012. A request for bids for construction of the slow-fill CNG fueling station was issued in February 2011. The bid was awarded to Amtek Construction in April 2011. Numerous problems and delays plagued this project, and the station did not begin dispensing fuel until January 2014.
The first objective of this project was to replace seven (7) diesel-powered refuse collection trucks with CNG-fueled vehicles. The second objective was to provide the City's CNG fleet with access to a slow-fill CNG fueling station at the location where trucks are housed, that was capable of fully fueling vehicles overnight.
The large capacity of the CNG fueling station was designed to accommodate the expected addition of CNG vehicles to the City's fleet for many years to come.
While the seven vehicles purchased in 2007 with partial MSRC funding were sold before the CNG fueling station was completed, the City has continued to replace diesel-powered heavy-duty fleet vehicles with CNG vehicles, which are now being fueled at the new station. A heavy-duty CNG vehicle with a Cummins ISL G natural gas engine and an average use of 1,189 hours per year will generate 0.18 tons/year less oxides of nitrogen (NOx). Operating the seven refuse collection vehicles in the SCAQMD for 10 years will reduce total production of NOx by 12.6 tons.
