2-2.2 Fuel Module Plot Plans Cont'd.
suction head available to the pump. If it is necessary to install a module on a sloping terrain, it is best for safety reasons
to install the tanks on the lower side of the slope to avoid flooding the pump operating area with fuel in the event of a
tank and berm break. If possible, the difference in elevation between the pump pad and the tank should be held to a
maximum of 2 feet.
2-2.3 Tanker-Truck Receipt Manifold Plot Plan
a.
A tanker-truck receipt manifold detailed plot plan is not shown due to the variability and optional nature of the
manifold. The tanker-truck receipt manifold may be located off one side of the switching manifold, as shown on Fig. 2-2,
the overall plot plan.
b.
Note that 6-inch hoseline from the transfer hoseline assembly, is used to connect the tanker-truck receipt
manifold to the switching manifold. The use of the hoseline gives considerable flexibility to the exact location of the
receipt manifold in the TPT.
c.
The most important factor in choosing the exact site for the tanker truck receipt manifold is road access, since it
is probable that much heavy truck traffic will occur in this area of the TPT. A graded area 120 ft. wide x approximately
700 ft. long is recommended.
2-2.4 Fuel Dispensing Assembly Plot Plan
The fuel dispensing assembly plot plan requirements are as shown on Fig.'s 2-2, 2-3a, 2-4a, and 2-5a. The fuel
dispensing assembly is approximately 525 ft. long. It is recommended that a section at least 50 ft. wide and 600 ft.
long be graded for the fuel dispensing assembly itself. An area alongside 120 ft. wide x approximately 700 ft. long
should be graded for vehicle traffic and parking while loading.
2-2.5 Contaminated Fuel Module Plot Plan
a.
The contaminated fuel module's plot plan is shown in Figure 2-6. The contaminated fuel module will be located
between the associated pipeline and the switching manifold within the TPT (see Fig. 2-2, TPT Overall Plot Plan).
b.
The two 50,000 gallon collapsible fabric tanks will each require a level area approximately 60 ft. x 100 ft. (46 ft.
x 86 ft. if sand bags are used) for the tank/berm location, if the installation authority chooses to have them with separate
berms. If the two tanks are installed within a common berm, an area of approximately 105 ft. x 100 ft. (96 ft. x 87 ft., if
sand bags are used) is required.
c.
Space must be provided for the 350 gpm transfer pump used with the contaminated fuel module.
d.
Road access must be provided to the contaminated fuel module to allow tanker-trucks to load the contents of the
50,000 gallon tanks as required. A graded area 40 ft. wide x approximately 100 ft. long is recommended
2-2.6 50,000 Gallon Tank TPT Optional Configuration Plot Plan
a.
Included in a complete TPT are up to six (6) 50,000 gallon fabric collapsible tanks and the necessary valves,
hose and fittings to connect them. The bank of tanks can be used
