Why This Topic? • Fueling Infrastructure is Aging • No Real Data on Life Expectancy of Systems • Limited Opportunities to be Involved in the Construction of these Facilities • Need a Working Knowledge
Components of an Aviation Fueling System Specific Environmental Concerns Rules and Regulations that Govern Fueling Facilities
Pipeline or truck receiving Filtration Fuel storage (Horizontal or Vertical Tanks) Pumping and controls Secondary containment
Inbound filtration to remove
water, surfactants and/or particulates Floating suction Tank floor sloped to sump Outbound filtration
Filtration at aircraft

Tank/piping cathodic
protection Reference wells Tank gauging
Routine inspections Tank Ringwall Foundation
Tank Floor CP
Containment beneath the tank Dike walls and berms sized for largest tank Impermeable liners Double walled tanks

Medium Airports
Large Airports Truck Fueling 10%
Hydrant System 90%
Truck Fueling 33%
Hydrant System 67%
• Piping system to aircraft • Isolation valve pits/vaults • High points and low points
• Hydrant pits • Emergency Fuel Shutoff (EFSO)
Welded steel piping 100% x-ray of joints Single vs. double wall piping Leak detection systems
Leak Detection
Concrete or fiberglass
construction Isolation for leaks/spills
Isolation for maintenance
and construction
Used to remove water and air from the system Flanged connections inside pit Seal at pit wall penetration is critical Low points serviced monthly, high points quarterly
Pit construction is similar to high/low points Point of connection between piping system and aircraft Regulates pressure into the aircraft Final chance to filter Maintained on a daily basis
Required by code
Positive means to shut down the flow of fuel in an emergency
Shut Down Pumps or Close Valves to Isolate Gates
Within Line of Site of Fueling Operation
Used where hydrant systems are not available
or as backup Equipment provided to prevent truck overfills Fuel is metered and filtered Sized secondary containment Foam fire protection in some jurisdictions
Site investigations for property transfer Pre-construction planning and investigations Lead paint and asbestos
Lease negotiations Construction management Emergency response and investigation Remediation and reporting Operating Plans & Permits (Air/SPCC/FRP/SWPPP)
