Date: 6 April 2011iv EXECUTIVE SUMMARY

The scope of this project is to perform bienni al integrity testing of Bulk Field Constructed
Underground Storage Tank (BFCUST) 4 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 4 was Mass Technology Corporation (MTC) integrity tested from 9 March to 17 March

2011 with no detectable leak above the test met hod’s minimum detectable leak rate of 0.7 gallons
per hour (gph) resulting in a passing test result.

BFCUST 4 should be retested on or before the biennial anniversary da te of 17 March 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 integrity testing of Bulk Field Constructed Underground Storage Tank
(BFCUST) 4 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 4 is 100 feet in diameter, 250 feet in height and has a capacity of 12,600,000 gallons of

JP-8. 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

Historical records show that the last test pe rformed on BFCUST 4 occurred in June 2009 with
passing results.

1.4 Project Scope

A Mass Technology Corporation (MTC) integrity test on BFCUST 14 was performed from 9
March to 17 March 2011. 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 4. 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 the integrity 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 INTEGRITY TESTING AND RESULTS

MTC’s test report is provided in Appendix A. BF CUST 4 was integrity 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 4 passed the 2011 biennial integrity testing.

3.2 Recommendations

As a DLA BMP, BFCUST 4 should be retested on or before the biennial anniversary date of 17

March 2013.

Summary

Testing of Tank # 4 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl Harbor, Hawaii commenced March 9, 2011 and was completed March1 7 , 2011 . The tank was filled
with JP

- 8 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 containment integrity of the tank was not compromised and the test is considered conclusive.

Tank # 4 : After 1 68 hours of testing the tank is certifi ed 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 t ank 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 # 4 is certified to be tight
