1.2 Site Background and History

In 2010, Naval Station Pearl Harbor and Hickam Air Force Base (AFB) were merged into JB

Pearl Harbor

- Hickam combining the two historic bases into a single joint installation to support

both Air Force and Navy missions, along with the 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 May 31, 1935, was dedicated as

Hickam AFB. Together, the two bases play a central role in the Pacific theater and constitute a

vital part of the United States defense establishment today.

The Red Hill underground fuel storage facility consists of 20 BFCUSTs loca ted hundreds of feet

below ground and was constructed between 1940 and 1943 to replace vulnerable aboveground

fuel storage tanks that were located around Pearl Harbor. The BFCUSTs at Red Hill are

accessible through a tunnel system. The top tunnel runs ap proximately 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 accessible and have isolation valves immediately

adjacent to each tank within the low er tunnel. BFCUST 20 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 te st event of BFCUST 20 , a Mass Technology Corporation (MTC) leak

detection test conducted from 11 March to 18 March 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 20 was performed from 24 January through 31 January

2013 . Table 1

1.5 Project Team

Baker subcontracted MTC to perform the leak detection testing. Field

- testing oversight,

coordination with facility fuels representat ives, 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

System s SIM

- 1000 / CBU

- 1000 ( 

### 72 hour test) leak detection method. Determination of leakage

is based on the criteria established in the Ken Wilcox Associates third party evaluation (National

Work Group on Leak Det ection Evaluations [NWGLDE, 2012])

. The MTC Prec ision 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 for declaring a leak. Through standard statisti cal

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

detectable leak above the test method’s minimum detectable leak rate (MDLR) of 0.7 gallons per

Summary

Testing of Tank # 20 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl

Harbor, Hawaii commenced January 24

, 2013 and was completed January 31 , 2013 . The tank

c ontained 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 th at 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 c ontainment integrity of the tank was not

compromised and the test is considered conclusive.

Tank # 20 : 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 # 20 is certified to be tight
