Date: 12 March 2012iv EXECUTIVE SUMMARY

The scope of this project is to perform biennial leak detection testing of Bulk Field Constructed
Underground Storage Tank (BFCUST) 2 at Joint Base (JB) Pearl Harbor – Hickam / Red Hill,
Hawaii. There are currently no regulations that outline test requirements for BFCUSTs at Red
Hill. This test was performed as a Defense L ogistics Agency (DLA) Energy best management
practice (BMP).

BFCUST 2 was Mass Technology Corporation (MTC) leak detection tested from 1 February to 9
February 2012 with no detectable leak above the test method’s minimum det ectable leak rate of
0.7 gallons per hour (gph) resulting in a passing test.

BFCUST 2 was out of service during the initial test event in January through March 2011.
BFCUST 2 was placed back in service in December 2012. BFCUST 2 should be retested on or
before the original biennial anniversary date of February 2013.

### 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-3000-0004
to perform biennial leak detection testing of Bulk Field Constructed Underground Storage Tank
(BFCUST) 2 at Joint Base (JB) Pearl Harbor – Hickam / Red Hill, Hawaii. There are currently
no regulations that outline test requirements for BF CUSTs at Red Hill. This test was performed as
a DLA Energy best management practice (BMP).

1.2 Site Background and History

BFCUST 2 is 100 feet in diameter, 250 feet in height and has a capacity of 12,600,000 gallons of

JP-5. The BFCUSTs at Red Hill are constructed within Red Hill and are accessible through an
underground tunnel system. The top tunnel is located approximately 60 feet below the top section

of the tank. The bottom tunnel is located at the same elevation as the tank’s base. The issue /
receipt and water drain pipelines are adjacent to the tank and immediately accessible from within

the lower tunnel.

1.3 Historical Leak Detection Results

The first DLA Energy test was performed on the tank in 17 June 2009 with passing results.

1.4 Project Scope

A Mass Technology Corporation (MTC) leak det ection test on BFCUST 2 was performed from 1
February to 9 February 2012. Table 1-1 provides a description of the system tested. Figure 1-1
provides a detail of the Red Hill system layout and location of BFCUST 2. Figures 1-2 and 1-3
provide photographs of typical top and bottom of tank access.

### 4 1.5 Project Team

Baker subcontracted MTC to perform leak detecti on 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 (PMMS) SIM-1000 / CBU-1000 (72 hour test ) leak detection method. Determination of
leakage was based on the criteria established in th e Ken Wilcox Associates third party evaluation.
The MTC - PMMS (72 hour test) is certified with a capability to detect leaks on a tank with a
product surface area of 7,850 square feet at a rate of 0.35 gallons per hour (gph), 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. This time frame included 48 hour
stabilization and two 72 hour test periods. The tw o 72 hour tests were averaged to achieve a

conservative minimal detectable l eak rate (MDLR) of 0.7 gph.

The description of the National Work Group on L eak Detection Evaluations (NWGLDE, 2011)
for MTC’s - PMMS 72 hour test is provided below:

72 hour test 50,000 gallons or greater
Leak rate is proportional to product surface area (PSA).
For tanks with PSA of 14,200 ft2, leak rate is 0.638 gph with P D = 95% and P FA = 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.

### 5 2.0 LEAK DETECTION TESTING AND RESULTS

MTC’s test report is provided in Appendix A. BFCUST 2 was leak detection tested with no

detectable leak above the test method’s MDLR of 0.7 gph. Test results are listed in Table 2-1.

3.0 CONCLUSIONS AND RECOMMENDATIONS

3.1 Conclusions

BFCUST 2 passed the 2011 biennial leak detection testing.

3.2 Recommendations

As a DLA Energy BMP, BFCUST 20 should be ret ested on or before the biennial anniversary
date of 1 February 2013.

Summary

Testing of Tank # 02 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl Harbor, Hawaii commenced February 1 , 201 2 and was completed February 9 , 201 2 . The tank was
filled with 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 # 02 : 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 # 02 is certified to be tight
