FUEL STORAGE TANKS
7.1. General Information. The majority of the aboveground storage tanks used for Air Force
petroleum products are built according to API Std 650, Welded Steel Tanks for Oil Storage, API Std
653, and Air Force standard designs. See Figure 7.1.
Figure 7.1. Air Force Standard Tank.
New belowground horizontal cylindrical storage tanks must be constructed in accordance with UL 58,
Steel Underground Tanks for Flammable and Combustible Liquids, and conform to environmental
requirements of 40 CFR 280, Technical Standards and Corrective Action Requirements for Owners and
Operators of Underground Storage Tanks (UST), current edition, and typically should be double-walled
Type II tanks. Current criteria for aboveground and belowground bulk storage tanks storing aviation
fuels require installing a product recovery tank to remove water from tanks. The product recovery tanks
should also be programmed for installation on existing facilities without water draw-off systems
(Figures 7.2 and 7.3). Motorized pumps are used on new systems, and where an electrical power source
is readily available and the additional cost can be justified; hand-operated pumps must be used on all
other installations. Product recovery systems are not required on ground product bulk storage tanks
(e.g., diesel, heating fuels); however, it may be desirable to have such a system installed on bulk
MOGAS storage tanks. This system should only be installed on aboveground bulk MOGAS storage
tanks with a capacity of 2000 barrels or larger. Operating instructions are in T.O. 37-1-1.
