EXECUTIVE SUMMARY 

The scope of this project is to perform biennial integrity testing of Bulk Field Constructed 

Underground Storage Tank (BFCUST) 8 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 Logistics Agency (DLA) Energy best management 

practice (BMP). 

BFCUST 8 was Mass Technology Corporation (MTC) integrity tested from 4 March to 11 March 

2011 with no detectable leak above the test method’s minimum detectable leak rate of 0.7 gallons 

per hour (gph) resulting in a passed test result. 

BFCUST 8 should be retested on or before the biennial anniversary date of 11 March 2013.

1.0 INTRODUCTION 

1.1 Purpose of Project

The Defense Logistics Agency (DLA) Energy contracted 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) 8 at Joint Base 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 

DLA Energy best management practice (BMP).

1.2 Site Background and History

BFCUST 8 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 runs approximately 60 feet below the top 

section of the tanks and 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 performed on BFCUST 8 occurred in May 2009 with 

passing results. 

1.4 Project Scope

A Mass Technology Corporation (MTC) integrity test on BFCUST 8 was performed from 4 

March to11 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 8. Figures 1-2 and 1-3 

provide photographs of typical top and bottom of tank access.

1.5 Project Team

Baker subcontracted MTC to perform the integrity testing. Oversight, coordination with facility 

fuels representatives, quality assurance/quality controls (QA/QC), 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 is based on the criteria established in the 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 two 72 hour tests were averaged to achieve a 

conservative minimal detectable leak rate (MDLR) of 0.7 gph. 

The description of the National Work Group on Leak 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 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.

2.0 INTEGRITY TESTING AND RESULTS 

MTC’s test report is provided in Appendix A. BFCUST 8 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.

3.1 Conclusions

BFCUST 8 passed the 2011 biennial integrity testing. 

3.2 Recommendations

As a DLA BMP, BFCUST 8 should be retested on or before the biennial anniversary date of 11 

March 2013.

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

to perform the required annual tightness testing of Tank # 08 an

underground fuel storage tank located at FISC Red Hill, Pearl Harbor, HI.

Summary

Testing of Tank # 08 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl 

Harbor, Hawaii commenced March 4, 2011 and was completed March 11, 2011. 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 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 # 08: After 168 hours of testing the tank is certified to be tight.

Results

The fluid mass data was recorded over a 168-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 gallons 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 # 08 is certified to be tight.
