30. Project Manager Contractor’s Project Manager assigned to this project shall be experienced in work like that proposed herein, with at least two years of direct or closely related work experience. Contractor warrants that the Operations Director named in this agreement will remain as Project Manager through the duration of the contract unless a replacement is approved in writing by OCTA.

31. Maintenance Personnel Maintenance personnel who will perform PM and respond to callouts shall have demonstrated experience and competency in maintaining other similar CNG equipment, with at least two years of recent experience.

32. Throughput Performance Test

32.1 OCTA may require a performance test at any time during the contract period in order to verify the performance of the Facilities.

32.2 Tests shall be performed while fueling CNG buses simultaneously from fueling lanes, to verify that the system meets the minimum flow rates specified. Facilities shall be tested to verify their actual throughput performance using the following procedure. The test shall be conducted under conditions reasonably representative of normal operating conditions existing at the time of testing:

Dispensers shall be calibrated on site, prior to throughput performance test, by a third party approved by OCTA and Contractor.

CNG Buffer storage shall be full and the single largest CNG compressor shall be taken off-line. All remaining CNG compressors shall be on-line.

Fueling lanes and dispensers shall be on-line. A test fleet of 20 CNG buses shall be used, and each bus shall be at no more than 2,000 PSIG prior to the test.

The test shall begin when dispensers are connected to buses and dispensers are started simultaneously. The test start time (time of day) shall be noted.

Buses shall be fully filled as determined by the dispenser auto-fill completion. Buses shall be continuously fueled as each preceding bus completes fueling, regardless of lane.

Actual fill volume dispensed at each fill event shall be logged, based on dispenser display following each dispenser auto-fill completion.

Dwell time (i.e. time between auto-fill completion of bus ‘A’ and start of fuel flow to bus ‘B’ at a given lane/dispenser) between all test-fueling events shall be controlled and limited as closely as possible to 90 seconds by OCTA’s Fuelers.

Completion of filling the final (20th) test bus shall mark the termination of the test and the time of day shall be logged and the elapsed time of the test shall be calculated.

Flow time and volume will be recorded for each bus fill. Fleet average flow rate is defined as total volume dispensed divided by total flow time.

The mass of CNG dispensed to the 20 test buses shall be aggregated and converted to standard cubic feet (SCF) of CNG.

The total aggregate SCF of CNG dispensed during the test, divided by the aggregate test time, shall equal at least 3,700 SCFM.

Five hours following fill completion: all test bus tank pressures shall be within three percent of 3,600 PSIG, temperature compensated to 70º F.

System is designed to deliver the observed throughput performance on a continuous basis.

33. Reliability Functional Test The gas monitoring and warning system at bus-fueling shall be tested three times annually (every four months) to show that the system is working properly and has been approved by the AHJs.
