MIL-HDBK-1022A
a) Provide a positive displacement or turbine meter
for each tank truck/car fill connection. Protect each meter
with an upstream strainer. Include temperature compensation if
rack is to be point of custody transfer.
b) Provide fuel sampling connections for collecting
test samples.
c) Provide pressure gauges on both sides of the
strainer or a differential pressure type across the strainer.
d) Provide fusible link safety valves as the first
piece of equipment (in the direction of the flow) on the
loading position. (Valve is not required on Air Force
projects.)
e) Provide hand-held deadman to control starting and
stopping of loading fuel. Ensure deadman interlocks to system
to prevent unattended loading of fuel. If electrical, use
intrinsically safe type only.
f) Make provisions to start and stop the pumps for
each fill position. Include pump status indicator light on
control box.
g) Equip each fill position with a self-checking,
automatic high-level shutoff system. Include an electronic
ground detector connected to an electrically controlled block
valve or pump so that the valve cannot remain open or the pump
cannot operate if the tank truck compartment is full or the
tank truck is not grounded. Ensure the system is compatible
with both electronic and fiber optic sensors with manual-keyed
bypass. (May require a parallel effort beyond the project
scope to ensure that all trucks using the facility have
compatible connections.) (This unit is optional on Air Force
projects. Contact the Service Headquarters for guidance.)
h) Equip liquid connections to tank trucks for
bottom loading with drybreak couplers in accordance with API
RP 1004.
i) Refer to Section 2 of this handbook for
guidelines on vapor collection and recovery or disposal
systems.
