In August 1998, the California Air Resources Board (CARB) identified diesel particulate matter (PM) as a toxic air contaminant, which can potentially cause cancer and other adverse health effects. By September 2000, the CARB adopted the Diesel Risk Reduction Plan to reduce PM emissions from diesel-powered engines and vehicles. This plan recommended emission control measures to reduce diesel PM and established a goal of reducing diesel PM by 75% by the year 2010 and 85% by 2020. In June 2000, the South Coast Air Quality Management District adopted Fleet Rule 1193 for on-road solid resources collection vehicles. This rule requires solid resources collection fleet operators to acquire alternative-fueled heavy-duty vehicles when purchasing or leasing vehicles to reduce air toxic and criteria pollutant emissions. In June 2000, the Los Angeles City Council adopted a Clean Fuel Policy, which guides the City of Los Angeles, Bureau of Sanitation (BOS) in developing a comprehensive strategy in supporting and expanding the use of alternative-fueled vehicles. In March 2006, Mayor Antonio Villaraigosa directed the BOS to convert its entire SRCV fleet to those operating on clean fuels by 2010. In January 2001, the BOS acquired its first 10 dual-fuel solid resources collection vehicles (SRCVs) operating on a combination of clean fuel, liquefied natural gas (LNG, 85%) and ultra-low sulfur diesel (ULSD, 15%). Currently, the BOS has more than 300 LNG-powered SRCVs in its fleet of over 700 vehicles. In FY 06-07, the City of Los Angeles acquired and placed in service fifty LNG-powered SRCVs. The City was awarded a funding support from the Mobile Source Air Pollution Reduction Review Committee (Grant Agreement number AB2766/ML06022) to offset the cost of purchasing these clean fuel vehicles.

All fifty liquefied natural gas (LNG)-powered solid resources collection vehicles were acquired and deployed in the City of Los Angeles, Bureau of Sanitation (BOS) fleet between December 2006 and November 2007. These vehicles are currently assigned in various district collection yards of the BOS and are continually operated 100% of each vehicles annual mileage in the South Coast Air Basin.
The objective of this project was the continued support for the Citys commitment in providing its residents with clean air quality by reducing criteria pollutants and toxic air emissions from its fleet of heavy-duty solid resources collection vehicles (SRCVs). Contract agreement number AB2766/ML06022 from the Mobile Source Air Pollution Reduction Review Committee (MSRC) Clean Transportation provided funding to the City of Los Angeles, Bureau of Sanitation (BOS) a maximum award of $1,250,000 for the purchase of fifty SRCVs equipped with dedicated liquefied natural gas (LNG) engines. The total cost for the fifty LNG-powered SRCVs including tax amounted to $11,144,589.25. With the MSRCs contribution, their funding support for this project amounted to 11.2%. The City of Los Angeles issued purchase order number 643406 in 2006 for the procurement of fifty LNG-powered SRCVs. All fifty SRCVs are 2007 Condor PRL-42L model equipped with 8.9L Cummins ISL Gas Plus engine (2006 engine model year). The first twenty-five SRCVs are equipped with Amrep automated side loader solid resources collection bodies and fuel tanks with a capacity of 150 gallons. The final twenty-five SRCVs are equipped with Amrep front loader solid resources collection bodies and fuel tanks with a capacity of 119 gallons. All SRCVs are fueled with LNG and have been deployed in the BOS fleet between December 2006 and November 2007. As the BOS started receiving the new vehicles, BOS staff was experiencing performance issues with the vehicles, specifically with the acceleration and overall operation. BOS operational needs were not met, but with staff assistance the manufacturer was able to address the problems. After manufacturer modifications, the new LNG-powered SRCVs were able to perform at an acceptable level. These improved modifications made to the vehicle performance caused a delay in the delivery and deployment of the fifty LNG-powered SRCVs in the BOS fleet. However, as of November 2007, all fifty LNG-powered SRCVs that are funded in part under the MSRCs Contract Agreement number AB2766/ML06022 have been received and placed in service. All of these vehicles are presently operated in the South Coast Air Basin.
PROJECT EXPANSION & REPLICATION POTENTIAL:
With the use of these fifty liquefied natural gas powered solid resources collection vehicles, this project will avoid the combustion of more than 0.5 million gallons of diesel per year or more than 5.5 million gallons of diesel for this 10-year project. It is estimated that this project would also result in emissions reduction of approximately 105.2 tons of NMHC + NOx and 11.8 tons of PM.
