1.0 INTRODUCTION

Environmental Science Corporation (ESC) received contract number W912HV-11-P-0038 from the U.S.

Army Corps of Engineers (USACE) Japan Engineer District (JED) to conduct underground storage tank

(UST) tightness testing and prepare an economic analysis of UST verses aboveground storage tank

(AST) lifecycle costs at Naval Air Facility (NAF) Atsugi, Japan.

This report presents results of UST tightness testing. The objective of this project was to conduct an integrity testing on UST systems including associated fuel lines that do not have permanent leak detection systems, as required by Chapter 19 of the Japan Environmental Governing Standards (JEGS)

(U.S. Forces Japan [USFJ], 2010).

2.0 TESTING SITE LOCATIONS

ESC conducted integrity testing on thirteen UST systems under this contract. All UST systems were located at NAF Atsugi, Kanagawa, Japan. Tank locations are shown in Figure 1.

3.0 TIGHTNESS TESTING METHOD

The VacuTect™ tank testing system was employed for all UST system tightness testing under this contract. This tank testing method is an independent third party verified test method capable of meeting the detection requirements required by JEGS Chapter 19 and the project SOW. Individual technician and third-party tank test method certifications are included in Appendix B and Appendix C of this report. The test method is described in further detail in Section 3.1.

3.1 VACUTECT

TM

METHOD

VacuTect™ is a reduced pressure (vacuum) based test method. During the VacuTect™ process, the ullage of the tank is subjected to a slight vacuum. When a leak is encountered, negative pressure

(vacuum) recovers, and bubbles are formed at the hole. The formation of bubbles produces a distinctive sound signature which is recorded using a high-quality hydrophone. Similarly to bubbles, above fuel-level leaks produce a high-pitched whistling sound that is also recorded. Leaks below groundwater level are detected using a sensor that records changes in the level of water inside the tank. The VacuTect™ process is applicable to both fuel tanks and directly connected pipelines.

Under JEGS, UST system integrity testing methods must be capable of detecting a 0.1 gallons-per-hour

(gph) leak rate with a probability of detection of 95% and probability of false alarm of 5% from any portion of the tank that routinely contains product while accounting for the effects of thermal expansion or contraction of the product, vapor pockets, tank end deflections, evaporation or condensation, temperature change, wind, vibration, noise, and the location of the water table (USFJ, 2010).

VacuTect™ is a National Work Group on Leak Detection Evaluations (NWGLDE) third-party certified test method which meets both JEGS and USEPA requirements for tightness testing methods. For more information on NWGLDE and the VacuTect™ test method, visit http://www.nwglde.org.

4.0 FIELD EFFORT

4.1 PRELIMINARY SITE VISIT

A preliminary site visit was conducted on 9 January 2012 after the project start-up meeting. The site visit included a visual inspection of facilities for testing, meetings with NAF Atsugi Environmental and

Facilities Maintenance staff, and data gathering. Information gathered during the site visit is shown in individual tank reconnaissance survey forms included in Appendix D.

4.2 UST SYSTEM TESTING

UST system integrity testing was conducted in two separate mobilization split into two days each during

January and February 2012. A second mobilization was required because of Navy Exchange (NEX) gasoline station renovation construction. Integrity testing methods and procedures were performed in accordance with the project work plan (ESC, 2011). After completion of testing, fuel systems were restored to their original conditions. Final operational testing of each tested system was coordinated with facility operators at the site immediately following UST system restoration.

The project field execution schedule is shown in Table 1. This table describes total field effort, including site preparation, testing efforts, and site restoration activities.

6.0 RECOMMENDATIONS

General recommendations are:

1. Conduct tightness testing annually for USTs without functioning automatic leak detection systems using a test method which meets USEPA requirements in accordance with JEGS requirements.

2. Ensure that pipeline repair / replacement incorporates JEGS requirements for automatic leak detection equipment and/or double-wall construction as appropriate. Pipeline leak detection systems should be compatible with their associated UST / facility leak detection systems.

3. Existing USTs and piping that do not meet the requirements of Section 19-3.2 of the JEGS should be properly closed if not needed, or be upgraded or replaced to meet new UST system requirements as required by the JEGS.

APPENDIX B

VACUTECTTM 3RD PARTY CERTIFICATION

VacuTect

NON-VOLUMETRIC TANK TIGHTNESS TEST METHOD (VACUUM)

Certification Leak rate of 0.1 gph with PD = 100% and PFA = 0%.

Leak Threshold

A tank system should not be declared tight when:

sonic emission of air ingress is detected in ullage area and/or; sonic emission of bubbles formed by air ingress is detected in product-filled portion of the tank and/or; water ingress is detected by the water sensor.

Applicability Gasoline, diesel, aviation fuel, fuel oil #4, waste oil.

Other liquids may be tested after consultation with the manufacturer. Water miscible products limit the effectiveness of water ingress detection.

Tank Capacity

Maximum of 75,000 gallons.

Test is generally conducted with tank between 60 and 95% full.

However, test may be performed at minimum 5% full if total ullage volume does not exceed 20,000 gallons.

Maximum of 30,000 gallons per tank and 60,000 gallons cumulative capacity for manifolded tank systems with microphone (hydrophone) and water sensor in each tank.

Waiting Time None between delivery and testing.

Test Period Minimum not specified to declare a tank "non-tight".

There must be no dispensing or delivery during test.

When water level in tank excavation backfill is below bottom of tank:

Minimum of 1 hour to declare tank tight.

When water level in tank excavation backfill is above bottom of tank:

Minimum to declare a tank tight may need to be extended because a water sensor must be used.

When water level in tank excavation backfill is not determined:

Minimum to declare a tank tight may need to be extended because a water sensor must be used.

To determine test period, water level in tank excavation backfill must be assumed to be just above bottom of tank.

When using a water sensor, the test period is determined based on tank size, water level inside tank prior to test, tank tilt, type of water sensor, water sensor location in the tank, and water level in tank excavation backfill relative to bottom of tank. Tank tilt is determined by an inclinometer, or by measuring tank bottom elevations at two points within tank. Water sensor is placed in low end of tank or in pre-existing cross section of water inside tank.

For example:

For a printed circuit board water sensor, the test period to detect a 0.1 gph leak rate in a 10,000 gallon (96"dia x 324"lg) level tank without a striker plate and without water in the tank is 51 minutes for water ingress to contact the water sensor plus 38 minutes to allow the sensor to detect the "minimum detectable change in water level" (see "Water Sensor" section below).

For example:

For a magnetostrictive water sensor, the test period to detect a 0.1 gph leak

NAF Atsugi UST Tightness Testing B-1 W912HV-11-P-0038 rate in a 10,000 gallon (96"dia x 324"lg) level tank without a striker plate and without water in the tank is 37 minutes for water ingress to contact the water sensor plus 2 minutes to allow the sensor to detect the "minimum detectable change in water level" (see "Water Sensor" section below).

Test Pressure Required test pressure is a function of tank construction, burial depth, product level in the tank, and water level in tank excavation backfill.

Pressure differential across tank wall at the bottom of the tank must be at least

0.5 psi.

Pressure differential across the tank wall is equal to the absolute value of vacuum applied to tank, plus the pressure of the tank excavation backfill on tank, plus groundwater pressure on tank, minus pressure of liquid in tank.

If water level in tank excavation backfill is not determined by wells, probes or pump boxes in the tank excavation backfill, test pressure calculation must account for both:

1) water level just above bottom of tank to achieve minimum 0.5 psi at worst case condition, and

2) tank completely submerged to assure tank is not damaged from over pressurization.

Temperature Sonic emission and water ingress are independent of product temperature.

Water Sensor Must be used if water level in tank excavation backfill is above tank bottom or if water level in tank excavation backfill was not determined.

Printed circuit board sensor minimum detectable water level is 0.022 inch, and minimum detectable change in water level is 0.016 inch.

Magnetostrictive sensor minimum detectable water level is 0.017 inch, and minimum detectable change in water level 0.001 inch.

Groundwater If groundwater level in tank excavation backfill is above bottom of tank, or if groundwater level in tank excavation backfill is not determined, test time must be sufficient to detect water ingress using one of the above water sensors.

Comments Evaluated using gasoline, diesel, Jet-A, and JP-4.

Microphone (hydrophone) should be located within 60 feet of any possible leak source.

Vacuum test method may not be effective in some tank excavation backfill (such as clay) because it may plug holes in tank.

If free product is present in tank excavation backfill, a leak in the free product zone may not be detected by a vacuum test method.

A well point or observation well in the tank excavation backfill can help identify the presence of free product, tank excavation backfill material, and water elevation in the tank excavation backfill.

More that 4 psi pressure differential across the tank wall at any location in the tank could damage tank.
