Los Angeles Sanitation Districts
to use liquefied natural gas in trucks
The Sanitation Districts of Los Angeles County
have begun using five liquified natural gas (LNG) trucks to transfer municipal
solid waste from Sanitation Districts’ transfer stations to landfills
for disposal. The LNG trucks are the latest addition to the Sanitation Districts’ comprehensive
clean fuels program, the goal of which is to replace Sanitation Districts’ wastewater
and solid waste operational vehicles with compressed natural gas and LNG
vehicles. The LNG trucks will be fueled at the Sanitation Districts’ LNG
fueling station located at the Puente Hills Materials Recovery Facility in
Whittier.
Cummins ISX 15-liter engines, equipped with Westport’s High Pressure
Direct Injection (HPDI) fueling system, power the LNG trucks. The HPDI system,
certified by the California Air Resources Board and the United States Environmental
Protection Agency, allows engines to operate at lower emissions using LNG
instead of diesel, as the primary fuel, using only a small quantity of diesel
as the starting ignition source.
Sixty percent of the cost of the vehicles was funded by
grants from the South Coast Air Quality Management District, the Gas Technology
Institute, and the California Energy Commission, agencies that hope to facilitate
continued deployment of these vehicles to reduce the impact of diesel emissions. |
