ASSEM BLY AND PREPARATION FOR USE. - continued
(3)
The location of the 5,000 bbl tanks and their berms are controlling factors in selecting a TPT site and layout.
If pairs of tanks must have a common berm wall, a cleared and leveled area approximately 215 ft. X 115 ft. is required for
each pair of tanks. (If sandbags are used to construct the berm, the area is approximately 190 ft. X 100 ft.) If the tanks
have individual berms, the area required for the tank/berm measures approximately 115 ft. X 115 ft. (approximately 100 ft.
X 100 ft. if sandbags are used).
(4)
Besides selection of level ground, another important factor in choosing tank location is the elevation of the
%' tank relative to the rest of the module. To allow for high vapor pressure, fuels, it is preferable to keep the tank bottom
and pump pad at about the same level to maximize 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. The pump pad should not be more than two feet
higher than the tank pad or it may be difficult to pump the tank dry when required.
g.
Contaminated Fuel Module Layout.
(1)
The contaminated fuel module will be located between the associated pipeline and the switching manifold
within the TPT (see figures 4-1 and 4-2, TPT Overall Layouts).
(2)
The two 50,000 gallons collapsible fabric tanks will each requires a level area approximately 60 ft. X 100 ft.
(46 ft. X 86 ft. if sandbags 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 sandbags are used) is required.
(3)
Space must be provided for the 350 gpm transfer pump used with the contaminated fuel module.
(4)
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.
h.
Fuel Dispensing Assembly Layout. 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.
i.
Tanker-Truck Receipt Manifold Layout.
(1)
The tanker-truck receipt manifold may be located off one side of the switching manifold, or next to the fuel
dispensing assembly.
(2)
A 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.
(3)
An important factor in choosing the exact side 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.
