Since 1943, the Defense Fuel Support Point (DFSP) San Pedro has been used to receive, store and distribute diesel and jet fuels for military use in California, Arizona and Nevada. In 1980, the Defense Fuel Supply Center branch of the Defense Logistics Agency assumed operations from the Navy. The DFSP currently utilizes 41 tanks to store various fuels and waste oil. Thirty-four of these storage tanks are underground and seven are aboveground. All the tanks and their piping are regularly inspected. The DFSP is located west of Long Beach.
