eiv EXECUTIVE SUMMARY

The scope of this project is to perform biennial leak detection testing of Bulk Field-Constructed Underground Storage Tank (BFCUST) 7 at Na val Supply Systems Command Fleet Logistics
Center Pearl Harbor – Joint Base Pearl Harbor-H ickam / Red Hill, Hawaii. There are currently no regulations that outline test requirements for BFCUSTs at Red Hill. The testing is being
conducted under Defense Logistics Agency (DLA) Ener gy’s Leak Detection Centrally Managed Program (CMP) as pollution prevention Best Management Practice (BMP).

BFCUST 7 was Mass Technology Corporation leak detection tested from 7 February through 14 February 2013 with no detectable leak above the test method’s minimum detectable leak rate of 0.7 gallons per hour resulting in a passed test.

Biennial leak detection testing of BFCUST 7 s hould be completed on or before the anniversary date of 14 February 2015 under DLA Energy’s Leak Detection CMP as pollution prevention
BMP.1 1.0 INTRODUCTION

1.1 Purpose of Project

The Defense Logistics Agency (DLA) Energy cont racted Michael Baker Jr., Inc. (Baker) through Naval Facilities Engineering Command (NAVFAC) Atlantic Contract N62470-10-D-3000-0026 to perform biennial leak detection testing of Bulk Field-Constructed Underground Storage Tank (BFCUST) 7 at Naval Supply Systems Command Fl eet Logistics Center Pearl Harbor – Joint Base (JB) Pearl Harbor-Hickam / Red Hill, Hawaii. There are currently no regulations that outline test requirements for BFCUSTs at Re d Hill. The testing is being conducted under DLA Energy’s Leak Detection Centrally Manage d Program (CMP) as pollution prevention Best Management Practice (BMP).

1.2 Site Background and History

In 2010, Naval Station Pearl Harbor and Hickam Air Force Base (AFB) we re merged into JB Pearl Harbor-Hickam combining the two historic ba ses into a single joint installation to support both Air Force and Navy missions, along with th e tenant commands, and all the service members
and their families. Pearl Harbor was established as a United States naval base in 1908. In 1934, the Army Air Corps began construction of the base that, on 31 May 31 1935, was dedicated as Hickam AFB. Together, the two bases play a centr al role in the Pacific theater and constitute a vital part of the United States defense establishment today.

The Red Hill underground fuel storage facility c onsists of 20 BFCUSTs located hundreds of feet below ground and was construc ted between 1940 and 1943 to replace vulnerable aboveground fuel storage tanks that were located around P earl Harbor. The BFCUSTs at Red Hill are accessible through a tunnel system. The top tunnel runs approximately 60 feet below the top
section of the tanks and the bottom tunnel runs equal to the bottom level of the tanks. The issue/receipt and water drain pipelines are acce ssible and have isolation valves immediately adjacent to each tank within the lower tunnel. BFCUST 7 is 100 feet in diameter, 250 feet in height, and has a capacity of 12,600,000 gallons of JP-5.2 1.3 Historical Leak Detection Results

The last biennial test event of BFCUST 7, a Mass Technology Corporation (MTC) leak detection test conducted from 14 January to 21 January 2011, showed passing results with no detectable leak above the test method’s minimum detectable leak rate (MDLR) (Baker, 2011).

1.4 Project Scope

A MTC leak detection test on BFCUST 7 was pe rformed from 7 February through 14 February 2013. Table 1-1 provides a description of the system tested. Figure 1-1 provides a base overview map. Figure 1-2 provides a layout of the Red Hill system.

Baker subcontracted MTC to perform the leak detection testing. Field-testing oversight, coordination with facility fuels representatives, quality assurance/quality controls, and final report preparation and submission was provided by Baker personnel.

1.6 Qualifications of Testing Procedures Used

The testing procedures used were those defined as the MTC - Precision Mass Measurement Systems SIM-1000 / CBU-1000 ( 

### 72 hour test) leak detection method. Determination of leakage
is based on the criteria established in the Ken W ilcox Associates third party evaluation (National Work Group on Leak Detection Evaluations [NWGLDE, 2012]). The MTC Precision Mass Measurement System ( 

### 72 hour test) is certified with a capability to detect leaks on a tank proportional to the product surface area with a probability of detection of 95 percent and probability of a false alarm of 5 percent. Due to the extreme height of the tank, a total of 168 hours of testing was performed.

By performing a number of non-overlapping tests in sequence and averaging the resultant leak rates, a modified threshold can be established fo r declaring a leak. Through standard statistical analysis, the larger the number of tests used in the averaging will result in a lower threshold and, therefore, a smaller size leak can be detected with a 95 percent probability of detection.6 2.0 LEAK DETECTION TESTING AND RESULTS

MTC’s test report is provided in Appendix A. BFCUST 7 was leak detection tested with no detectable leak above the test method’s MDLR of 0.7 gallons per hour (gph). Test results are
listed in Table 2-1.

Scope of Work: Furnish all required management, labor, services, materials and equipment

to perform the required annual tightness testing of Tank # 7 a n underground fuel storage tank located at FISC Red Hill, Pearl Harbor, HI.

Summary
Testing of Tank # 7 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl Harbor, Hawaii commenced Febr uary 7 , 2013 and was completed Febr uary 14 , 2013 . The tank contained JP

- 5 and a precision leak test was conducted. The result of that testing is that the tank system is determined to be tight to isolation. All tank valves were adequately secured such that no unusual readings were noted. Testing was performed using the Mass Technology Corporation protocols set out in the third party evaluations. All tank valves were adequately secured such that any fluid loss was isolated to leakage. Therefore, the contai nment integrity of the tank was not compromised and the test is considered conclusive.

Tank # 7 : After 1 68 hours of testing the tank is certified to be tight

### Results

The fluid mass data was recorded over a 1 68

- hour period. A linear regression of the recorded fluid mass data resulted in a leak rate detected below the minimum detection level of 0. 7 gallon s per hour. All tank valves were adequately secured such that any fluid loss was isolated to leakage. Therefore, the containment integrity of the tank was not compromised and the test is considered conclusive.

Tank # 7 is certified to be tight
