1.2 SUMMARY <br />A. This specification covers design, manufacture, and delivery of one (1) Compressed <br />Natural Gas (CNG) Vehicle Fueling System. The CNG system shall consist of, but not be <br />limited to, the following minimum components: <br />1. One (1) 200 SCFM electric motor -driven skid -mounted CNG compressor system <br />complete with integrated compressor and time fill system controls. Must be modular <br />in design to accommodate future expansion for Phase 2, which will be of the same <br />type and size system. <br />2. One (1) single tower low-pressure regenerative desiccant type gas dryer. Should <br />be sized and equipped to add future compressor same size and type proposed for <br />Phase 2 of the project. <br />3. Ten (10) dual hose metered time fill post assemblies with twenty (20) hose <br />assemblies. Installation will be such that existing traffic patterns and parking is <br />sustained. <br />4. Defueling Station: The defueling station will safely vent vehicles CNG Fuel Tanks as <br />required for vehicle maintenance to be located next to the CNG equipment as the <br />defueling vents gas back into the compressor inlet pipe stream. <br />1.3 CODES AND STANDARDS <br />Equipment and assemblies shall comply with all relevant provisions of the latest revisions <br />of approved codes and standards and current industry practices including the following: <br />A.
