Each of the 20 tanks at Red Hill can hold over 12 million gallons of fuel. The Navy currently uses several multiple methods in each tank to determine if leaks are occurring, including continuous monitoring of the fuel level, high precision annual tests to determine tank tightness, manual tank gauging, fuel inventory trend analysis and other operational measures.
As required by the AOC, the Navy and Defense Logistics Agency (DLA) investigated options for new and more precise fuel release detection methods. In 2018 the Navy and DLA evaluated a number of alternative fuel release detection methods. These new methods and the results of the evaluations are presented in the July 26, 2018 New Release Detection Alternatives Report (available for viewing below).
