EXECUTIVE SUMMARY 

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

Underground Storage Tank (BFCUST) 16 at Naval 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 Logistics 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 biennial anniversary date of 28 February 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) 16 at Naval Station 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 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 constructed 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.

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 detection 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, 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 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.

2.0 INTEGRITY TESTING AND RESULTS 

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

Summary

Testing of Tank # 16 a 12,600,000 gal underground storage tank located at FISC Red Hill, Pearl 

Harbor, Hawaii commenced February 21, 2011 and was completed February 28, 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 

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 # 16: 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 # 16 is certified to be tight.
