In fiscal year 1976, Air Force and Navy activities used about 120 million gallons of fuel for ground vehicles and other equipment. We visited 27 Air Force and Navy installations and tenant organizations having bulk storage facilities which issued a total of 12.9 million gallons of ground vehicle fuel during a recent 1-year period. Normally a single bulk storage and issue activity receives fuel from commercial sources or the Defense Fuel Supply Center (DFSC). In addition to these main installation fuel activities, many tenant organizations maintain their own bulk storage and mobile refueling activities. These organizations normally receive their petroleum from tank trucks operated by the installation fuels office. Or, they may receive it from commercial tank trucks under contract with the installation fuels office. As much as one-third of the fuel received by the base fuels activity is issued in bulk quantities to tenant organizations for storage and reissue.
