NYCT has two CNG operating depots—Jackie Gleason Depot in Brooklyn and West Farms Depot in the Bronx. The newly built West Farms CNG depot, shown in Figure 2, opened on September 7, 2003. An older depot, Coliseum Depot, was originally located where West Farms is now. West Farms has 157,000 square feet of office and maintenance space, outdoor parking for buses, and operates 256 buses including 163 CNG buses.
CNG fueling is provided under contract from Trillium USA and is integrated into the fueling island as shown in Figure 3. The CNG compressor station is outside the building (Figure 4) and includes three 800-horsepower compressors with a total output of 6,600 scfm. The capital cost for the facility was $7.4 million including $2 million for construction costs to blast through solid rock to install the underground natural gas lines. The current cost for compression and upkeep for the CNG station is $0.24 per therm or $0.32 per diesel equivalent gallon (in addition to the base natural gas commodity price).
