State: Virginia

Date: 11 March 2011iv EXECUTIVE SUMMARY

The scope of this project is to perform bienni al integrity testing of Bulk Field Constructed
Underground Storage Tank (BFCUST) 16 at Nava l Station (NAVSTA) Pearl Harbor / 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 16 was Mass Technology Corporation (MTC) integrity tested from 21 February to 28
February 2011 with no detectable leak above the test method’s minimum detectable leak rate of
0.7 gallons per hour resulting in a passed test result.

BFCUST 16 should be retested on or before the bien nial anniversary date of 28 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 integrity testing of Bulk Field Constructed Underground Storage Tank

(BFCUST) 16 at Naval Station Pearl Harbor / Red Hill, Hawaii. There are currently no
regulations that outline test requirements for BFCU STs at Red Hill. This test was performed as a
Defense Logistics Agency (DLA) Energy best management practice (BMP).

1.2 Site Background and History

BFCUST 16 is 100 feet in diameter, 250 feet in height and has a capacity of 12,600,000 gallons

of F-76. The BFCUSTs at Red Hill are constr ucted within Red Hill and 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 accessible immediately adjacent to each tank within the lower tunnel.

1.3 Historical Leak Detection Results

Historical records show that the last test performed on BFCUST 16 occurred in May 2009 with
passing results.

1.4 Project Scope

A Mass Technology Corporation (MTC) integrity test on BFCUST 16 was performed from 21
February to 28 February 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 16. 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 SIM-1000 / CBU-1000 (72 hour test) leak de tection method. Determination of leakage

is based on the criteria established in the Ken Wilcox Associates third party evaluation. The
MTC Precision Mass Measurement System (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, a nd 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 two 72 hour tests were averaged

to achieve a conservative minimal detectab le leak rate (MDLR) of 0.7 gph.

The description of the National Work Group on L eak Detection Evaluations (NWGLDE, 2011)
for MTC’s Precision Mass Measurement System 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 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.

### 5 2.0 INTEGRITY TESTING AND RESULTS

MTC’s test report is provided in Appendix A. BFCU ST 16 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 16 passed the 2011 biennial integrity testing.

3.2 Recommendations

As a DLA BMP, BFCUST 16 should be retested on or before the biennial anniversary date of 28
February 2013.

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

to perform the required annual tightness testing of Tank # 16 a n underground fuel storage tank located at FISC Red Hill, Pearl Harbor, HI.

Summary

Testing of Tank # 16 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl Harbor, Hawaii commenced February 2 1 , 2011 and was completed February 2 8 , 2011 . The tank
was filled with F

- 76 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

t hat 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 # 16 : 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 # 16 is certified to be tight
