The ABC Unified School District serves the cities of Artesia, Cerritos, Hawaiian Gardens, as well as portions of Lakewood, Long Beach, and Norwalk. ABC Unified includes nineteen elementary schools, five middle schools, three comprehensive high schools. ABC Unified provides pupil transportation services using diesel school buses. A few years ago, ABC Unified participated in a CNG bus demonstration program sponsored by the South Coast AQMD. As a result of the successful outcome of the demonstration, ABC Unified applied for grant funding under the AQMD's Low Emission School Bus Program. Funding for a total of nine (9) CNG school buses was awarded by the AQMD. To help offset the cost of constructing onsite CNG refueling, ABC Unified applied for, and was subseqently awarded, Clean Transportation Funding from the MSRC for the construction of a slow-fill CNG refueling station.

Station design and construction contractors were selected using a competitive bid process. Gase Equipment Systems, Inc. (GESI) was selected to construct the CNG refueling station. Station drawings were prepared and submitted to the City of Cerritos Planning Department for approval. Permits were also obtained from the Fire Marshall, ensuring that the station design and construction conformed with fire protection codes NFPA 52 and NFPA 57.
The objective of this project was to construct a time-fill (slow-fill) CNG refueling station at ABC Unified School District's bus parking and maintenance facility. The new CNG station provides convenient onsite refueling for ABC Unified's current fleet of nine CNG school buses.
The station experienced two failures during initial testing. A compressor piston failed, requiring replacement of the piston, valves, and associated components. Also, the methane detector was determined to be defective; this was sent back to the manufacturer for repair and has been subsequently reinstalled.
All station construction was completed as of June 2009. A station ribbon cutting ceremony was held on June 10, 2009. The station is currently providing daily refueling of ABC Unified's CNG bus fleet.
