The East Valley Liquefied and Compressed Natural Gas (LCNG) Fueling Station, located in the Sun Valley area of Los Angeles, is the largest LNG fueling facility in the United States, with an on-site storage capacity of 60,000 gallons of LNG. The LNG is used to fuel a fleet of approximately 120 LNG-powered refuse collection vehicles (RCVs) operated by the City. This facility also has the capability to re-gasify a portion of the LNG and to store and dispense it as CNG. The CNG is used to fuel a portion of the Citys growing fleet of CNG-powered street sweepers as well as other medium- and heavy-duty CNG vehicles that are being added to the Citys fleet as older diesel models are retired. The East Valley Yard, originally completed in 2004, has served as major fueling hub for City fleet vehicles since its development. The facility provides fuel to the home-based fleet of LNG-powered RCVs and dispenses CNG to vehicles based at eight (8) nearby City yards. As the Citys fleet of CNG vehicles has continued to quickly expand, so has the need for increased fueling capabilities. An Alternative Fuel Consolidation Report, prepared for the City in 2006, anticipated this increased demand and recommended that the pumping, vaporization, compression, and storage capabilities for CNG fuel be expanded at this site.

The goal of this project was to enhance the storage and dispensing capabilities of the CNG fueling station at the East Valley Yard in order to meet increased demand as the City's fleet of CNG vehicles continues to grow.
This upgrade and expansion project involved the installation of new, larger LNG pumps, an LNG vaporizor, new compressors, and three (3) additional CNG storage tubes. Additional work included site preparation, such as the installation of equipment pads, and other associated work such as tubing installation, replacement, and insulation. The end result is that the production of CNG has been made much more efficent and rapid while effectively doubling the amount of CNG stored and available at the site. This will allow for dependable and efficient fueling operations capable of meeting the increasing demand in this area, which will in turn allow City staff to provide vital services to the citzens of Los Angeles.
