Each of the 20 tanks at Red Hill can hold over 12 million gallons of fuel. The Navy currently uses two methods to determine if leaks are occurring, a continuous monitoring of the fuel level and an annual test to determine if the tank is leaking.
As required by the Administrative Order on Consent (AOC), the Navy and Defense Logistics Agency submitted a report that details the methods and procedures currently used to detect leaks inside each tank. This report was approved by the Regulatory Agencies on September 15, 2016.
In addition, the Navy and DLA must also examine whether new release detection alternatives can improve leak detection for the facility’s tanks. The results of this examination will be contained in a “New Release Detection Alternatives Report”. Based on this upcoming report, a decision will be made on the most appropriate and effective release detection procedures to apply at Red Hill.
A Scope of Work for Release Detection Alternatives was received on June 18th, 2017. This document establishes the steps and identifies the work required in order to develop the "New Release Detection Alternatives Report". This Scope of Work was conditionally approved by the Regulatory Agencies on July 26, 2017. Subsequent to the Regulatory Agencies' conditional approval, the Navy made a minor revision to the Scope of Work by adding a new "Section B - Background". Both versions of the Scope of Work and the Regulatory Agencies' conditional approval letter are available for viewing below.
