relevant jurisdiction(s). Engaging the authorities having jurisdiction (AHJs) at
the outset of the project will ultimately simplify the permitting process. Fire
marshals, zoning boards, and permitting agencies are examples of AHJs. Some
AHJs may have extensive requirements pertaining to fire detection and
extinguishing systems or seismic design. Americans with Disabilities Act
compliance may also affect the cost of the station or other facility design
parameters.
Metering System
Choosing to meter only the total fuel flow at the station, rather than
metering the amount used at each fast-fill dispenser, can typically decrease
equipment costs by approximately $15,000 per hose. However, metering only
total fuel flow may not allow for necessary data collection related to taxes,
revenues, expenses, or vehicle preventive maintenance.

power outage.
Backup Power Generator
Natural gas or diesel generators can be used to produce electricity to run
the compressor and auxiliary equipment in the event of a power outage.
Generator costs can range from $50,000 to $250,000, depending on the size of
the compressor it supports.
