The scope of this project is to perform biennial leak detection testing of Bulk Field

- Constructed

Unde rground Storage Tank 6 at Red Hill Underground Fuel Storage Facility, Joint Base Pearl

Harbor

- Hickam, Hawaii. There are currently no regulations that require test ing of bulk field

c onstructed u nde rground storage tanks at Red Hill. The testing is being conducted under De fense

Logistics Agency Energy’s Leak Detection Centrally Managed P ro gram as a pollution prevention

Best Management P ractice.

Bulk Field

- Constructed Unde rground Storage Tank 6 was Mass Technology Corpor ation leak

detection tested from 15 March through 22 March 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 Bulk Field

- Constructed Unde rground Storage Tank 6 should be

completed on or before the anniversary date of 22 March 201 5 under Defense Logistics Agency

1.0 INTRODU CTION

1.1 Purpose of Project

The Defense Logistics Agency (DLA) Energy contracted Michael B aker Jr., Inc. (Baker) through

Naval Facilities Engineering Command (NAVFAC) Atlanti c Contract N62470

- 10

- D

- 3000

- 0026

to perform biennial leak detection testing of Bulk Field

- Constructed Unde rground Storage Tank

(BFCUST) 6 at Red Hill Underground Fuel Storage Facility, Joint Base (JB) Pearl Harbor

Hickam, Hawaii. There are currently no regulations requiring the test ing of BFCUSTs at Red

Hill. The testing is being conducted under DLA Energy’s Leak Detection Centrally Managed

P rogram (CMP) as a pollution prevention Best Management P ractice (BMP)

.

1.2 Site Background and History

Pearl Harbor was established as a United States naval ba se in 1908. In 1934, the Army Air Corps

began construction of the base that, on May 31, 1935, was dedicated as Hickam Air Force Base

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

Harbor

- Hickam combining the two histo ric 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. T he base play s a central role in the Pacific theater and constitute s a vital part of th e

United States defense establishment today.

The Red Hill underground fuel storage facility was constructed between 1940 and 1943 to replace

vulnerable aboveground fuel storage tanks that were located around Pearl Harbor. The Red Hill

underground fuel sto rage facility consists of 20 BFCUSTs located hundreds of feet below ground

.
There are 2 rows of 10 (each) 12,600,000 gallon BFCUSTs. The BFCUSTs at Red Hill are

connected and accessible through two tunnel systems. A top tunnel runs approximately 60 feet

below the top of the tanks and a bottom tunnel runs along the bottom level of the tanks. The

issue/receipt and water drain pipelines connecting each BFCUST and Pearl Harbor are located in

the lower tunnel. All lines are equipped with Double Block and Ble ed Valves for isolation.

BFCUST 6 stores JP

- 8 and is 100 feet in diameter and 250 feet in height (capacity equals

12,600,000 gallons).2

1.3 Historical Leak Detection Results

The last biennial test event of BFCUST 6 , a Mass Technology Corporation (MTC) leak detection

test conducted from 6 February to 13 February 2011 , showed passing results with no detectable

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

(Baker, 2011).

1.4 Project Scope

A MTC leak detection test on BFCUST 6 was performed from 15 March through 22 March 2013

.

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

Systems 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, 201 3 ])

. The MTC Precision Mass

Measurement System ( 

### 72 hour te st) is certified with a capability to detect leaks on a tank

proportional to the product surface area (PSA) with a probability of detection (PD) of 95 percent

and probability of a false alarm (PFA) of 5 percent. Due to the extreme height of the tank, a to tal

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 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 PD

.

72 hour test 50,000 gallons or greater :

Leak rate is pro portional to PSA.

For tanks with PSA of 14,200 ft2, leak rate is 0.638 gph with PD = 95% and PFA = 5%.

For other tank sizes, leak rate equals [(PSA in ft2 ÷ 14,200 ft2) x 0.638 gph].

Example:

For a tank with PSA = 20,000 ft2; leak rate = [(20,000 ft2 ÷ 14,200 ft2) x 0.638 gph] = 0.898 gph.

Leak rate may not be scaled below 0.2 gph.6

2.0 LEAK DETECTION TESTING AND RESULTS

MTC ’s test report is provided in Appendix A. BFCUST 6 was leak detection tested with no

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

Summary

Testing of Tank # 6 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl

Harbor, Hawaii commenced M arch 1 5 , 2013 and was completed March 2 2 , 2013

. 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

contain ment integrity of the tank was not compromised and the test is considered conclusive.

Tank # 6 : 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 # 6 is certified to be tight
