Executive Summary 

Naval Facilities Engineering Command, Hawaii (NAVFAC Hawaii) prepared this preliminary 

Work Plan in response to the State of Hawaii Department of Health (DOH) release response 

letters dated February 12, 2014 and February 26, 2014 for the Red Hill Fuel Storage Facility. 

The objective of this Work Plan is to address the three elements described in the initial February 

12, 2014 letter and reiterated in the February 26, 2014 letter. 

The Facility is located in the south-central portion of the Island of Oahu, Hawaii, in Halawa 

Heights. There are 18 active and 2 inactive, 12.5 million gallon, field-constructed underground 

storage tanks (USTs) located at the Red Hill Fuel Storage Facility. A confirmed release of Jet 

Propellant 8, also known as Jet Propulsion fuel, type 8 (JP-8) from Tank 5 was reported on 

January 24, 2014. Immediately following notification to the DOH, the Navy collected 

groundwater samples from monitoring wells to determine if the release had impacted 

groundwater beneath the Facility or the nearby water supply well. Results indicated no fresh fuel 

from Tank 5 in the groundwater or drinking water samples. 

Summarized below is the Navy’s response to the DOH request to provide a preliminary work 

plan that includes three elements: 

1. Models to estimate downward vertical migration of free product – The Navy is in the 

process of hiring a qualified contractor with the expertise to perform this work. 

2. Methods or options for non-invasive scanning of basalt to determine area and volume of 

contaminant mass prior to any drilling investigation – The Navy has queried the subject 

matter experts (SMEs) at Navy headquarters in Washington, D.C. to determine if there 

are other known locations where this technology has been used. The SMEs indicate that 

modeling to investigate vertical subsurface movement of pure petroleum liquid product 

has not been undertaken at other Navy sites with similar subsurface features due to the 

unusual nature of the subsurface. 

3. Methods and locations for borings to most efficiently characterize the extent of 

contamination – The Navy is in the process of hiring a qualified contractor with the 

expertise to perform this work. Additionally, the Navy intends to evaluate various 

removal and remediation technologies that would be effective and feasible for future fullscale implementation. 

The Navy has implemented a comprehensive drinking water and groundwater monitoring 

program to ensure the safety and viability of the drinking water aquifer beneath the facility. The 

monitoring program includes collecting groundwater samples quarterly from U.S. Navy well 

2254-01 (RHMW2254-01) and three wells installed in the Facility lower access tunnel 

(RHMW01, RHMW02, RHMW05). The U.S. Navy well 2254-01 is located approximately 

3,000 feet downgradient from the Red Hill Fuel Storage Facility and provides a percentage of the 

potable water to the Pearl Harbor Water System. The groundwater samples are analyzed for 

petroleum constituents and compared against DOH Drinking Water Environmental Action 

Levels (EALs) (DOH, 2005a). 
Preliminary Work Plan 

Red Hill Fuel Storage Facility March 2014

Compliance sampling to date indicate that all Federal and State safe drinking water standards are 

attained. 

The Navy is committed to providing safe drinking water to its users as well as ensuring the 

safety of the surrounding Pearl Harbor aquifer for all other users, while operating and 

maintaining the Red Hill Fuel Storage Facility. To accomplish this, the Navy will continue to 

provide weekly status reports to the DOH and will communicate all aspects of the investigation 

and remediation with the DOH.

1.0 Introduction 

There are 18 active and 2 inactive, 12.5 million gallon, field-constructed underground storage 

tanks (USTs) located at the Red Hill Fuel Storage Facility (hereafter referred to as “the Facility”). 

The Facility is located at Joint Base Pearl Harbor-Hickam (JBPHH), Oahu, Hawaii. The Facility 

is operated by Naval Supply Systems Command (NAVSUP) Fleet Logistics Center Pearl Harbor 

(FLCPH). 

As requested in DOH letter U0204RT of February 12, 2014, and DOH letter U0210RK of 

February 26, 2014, this preliminary Work Plan presents methods for achieving the requirements 

in Hawaii Administrative Rules (HAR) 11-281 Subchapter 7, Release Response Action. The 

release response actions are required in response to the confirmed release of Jet Propulsion fuel 8 

(JP-8) from Tank 5. A copy of the DOH letter is presented as Appendix A. 

The following are included in this preliminary Work Plan: 

1. Models to estimate downward vertical migration of free product. 

2. Methods or options for non-invasive scanning of basalt to determine area and volume of 

contaminant mass prior to any drilling investigation. 

3. Methods and locations for borings to most efficiently characterize the extent of 

contamination. 

1.1 Background 

The following sections provide a description of the site and information on the Facility and USTs. 

1.1.1 Site Description 

The Facility is located in Halawa Heights on Oahu, Hawaii. Land adjacent to the north of the 

Facility is occupied by Halawa Correctional Facility and private businesses. Land to the south 

and west of the Facility includes the Coast Guard Reservation. Moanalua Valley is located east 

of the Facility (Dawson, 2006). Figure 1 shows the Facility location. 

The U.S. Navy Public Works Department operates a potable water supply shaft and associated 

pumping station, which, in spite of its largely lateral configuration is officially designated as 

“well 2254-01”. The station consists of a water infiltration shaft that is approximately 1,300 feet 

long connected to a water supply pumping station located approximately 3,000 feet 

downgradient (west) of the Facility. The pumping station provides a percentage of the potable 

water to the Pearl Harbor Water System, which serves approximately 52,200 military consumers 

(TEC, 2008). 

1.1.2 Facility Information 

The Facility consists of 18 active and 2 inactive USTs operated by NAVSUP FLCPH. Each 

UST has a capacity of 12.5 million gallons. The Facility is located approximately 100 feet above 

the basal aquifer (Dawson, 2006).

1.1.3 UST Information 

The USTs were constructed in the early 1940s. The tanks were constructed of steel and are 

currently used to store Jet Propellant 5, also known as Jet Fuel (JP-5), Jet Propellant 8, also 

known as Jet Propulsion fuel, type 8 (JP-8), and Diesel Fuel Marine (DFM, or F-76). Previously, 

several tanks stored Navy Special Fuel Oil, Navy Distillate, aviation gasoline, and motor 

gasoline. Each tank measures approximately 250 feet in height and 100 feet in diameter. The 

upper domes of the tanks lie at depths varying between approximately 100 feet and 200 feet 

below the existing ground surface (TEC, 2006). 

1.2 Groundwater Monitoring Wells 

Five groundwater monitoring wells were installed at the Facility: RHMW01, RHMW02, 

RHMW03, RHMW04, and RHMW05. The locations of the monitoring wells are shown on 

Figure 2. Boring logs and well construction logs are presented as Appendix B. 

RHMW01: From 1998 to 2001, the Navy conducted an investigation at the Facility to assess 

potential releases from the fuel storage Facility. In February 2001, the Navy installed a one-inch 

diameter sentinel well (MW-V1D) to monitor for contamination of the basal aquifer underlying 

the Facility. The well was installed and completed at approximately 100 feet below grade. At 

the time of well completion, depth to water in MW-V1D was measured at 86 feet below grade 

(Dawson, 2006). Monitoring well MW-V1D was later renamed RHMW01. 

RHMW02, RHMW03, RHMW04: As part of a site investigation, TEC, Inc. installed three 

groundwater monitoring wells at the Facility between June and September 2005. Well 

RHMW02 was installed in the lower access tunnel near Tanks 5 and 6. Well RHMW03 was 

installed in the lower access tunnel near Tanks 13 and 14. Well RHMW04 was installed 

hydraulically upgradient of the USTs to provide geochemistry for water moving through the 

basal aquifer beneath the Facility. Wells RHMW02 and RHMW03 were completed to depths of 

approximately 125 feet below the tunnel floor, and well RHMW04 was completed to a depth of 

approximately 300 feet below ground surface outside the tunnel. 

RHMW05: In April 2009, groundwater monitoring well RHMW05 was installed down-gradient 

from the Facility, within the lower access tunnel between RHMW01 and RHMW2254-01. The 

well was installed to identify contaminant migration before it reaches the infiltration gallery at 

RHMW2254-01. 

2.0 Vertical Migration Models 

At this time, it is unknown exactly where on Tank 5 the JP-8 release occurred and if or how 

much volume has migrated past the tank structure to the surrounding rock substrate. Since the 

monitoring wells located within the Facility were installed in the lower access tunnel, the boring 

logs for those monitoring wells provide geologic information for the subsurface located below 

the bottom of the USTs. To initiate the vertical modeling effort, the boring logs may be used to 

generalize the geology of the subsurface from the top of the ridge to the bottom of the USTs. 

A survey of subject matter experts (SMEs) at Navy headquarters in Washington, D.C. indicate 

that modeling to investigate vertical subsurface movement of pure petroleum liquid product has

5 

not been undertaken at other Navy sites with similar subsurface features due to the unusual 

nature of the subsurface: a combination of complex, alternating fractured and competent (i.e., 

“solid”) basalt rock layers with occasional thin layers of ash and other less competent rock. 

However, the Navy has extended the search for appropriate transport models for this type of 

environment. The Navy has initiated the process to hire a contractor with demonstrated expertise 

and experience with non-Navy sites with similar subsurface conditions to identify any 

appropriate models to estimate downward vertical migration of free product.

3.0 Non-Invasive Scanning 

A survey of Navy SMEs also indicate that there are no remote sensing (geophysical) applications 

for non-invasive scanning that can feasibly determine area and volume of contaminant mass in 

environments like the alternating competent/fractured basalt observed at the Facility. There is 

too much subsurface variability, complexity, and obstruction in the observed substrate for nonintrusive geophysical approaches such as seismic, ground penetrating radar (GPR), time-domain 

reflectometry (TDR), thermal, etc. to produce usable information. 

In the absence of useful geophysical methods, the usual approach for differentiating/ delineating 

the extent of contaminant plumes for saturated and unsaturated is by way of intrusive methods. 

Research done to explore options for minimally intrusive methods for characterizing near surface 

contamination such as laser induced fluorescence (LIF) with a direct push rig is intended for 

consistent nonconsolidated (e.g., soil) substrate and is not suitable for the competent /fractured 

basalt substrate at the Facility. 

Conversations within the Navy and with other agencies such as the United States Environmental 

Protection Agency (EPA) have indicated that the Facility is unique not only for the size of the 

features but also for the unusual nature and extreme complexity of the substrate. Therefore, the 

majority of conventional methods that would typically be appropriate for conventional-sized 

facilities with conventional conditions will either not be feasible or not yield usable information. 

The only two methods available to determine approximate area and volume of contaminant mass 

are borings for intervals of less competent rock, and coring to penetrate more frequent competent 

and fractured rock intervals, combined with sampling, in-field screening, and laboratory 

analytical confirmation analyses. The limitations of these available methods are that they 

provide information to a limited extent and are also the most involved in terms of cost, level of 

effort, and logistics, particularly factoring in the relative immensity of the tank size and the 

substrate. 

4.0 Methods and Locations for Borings 

Because the feasible intrusive sampling characterization methods will yield information on a 

comparatively localized area, the Navy will try to direct the investigation to the most appropriate 

area that can be practicably identified. Planned inspection of the Tank 5 interior after draining 

and safety preparations have been completed pose the best possibility of identifying the most 

appropriate area to localize the location of the release. The tank inspection will commence after 

Tank 5 has been vented and deemed safe for entry.

While the tank is being vented, the Navy will hire a contractor to determine methods and 

locations for borings to most efficiently characterize the extent of contamination. Based on the 

tank inspection findings, the contractor will be expected to propose locations to determine if the 

fuel might be trapped in the interstitial space between the steel tank wall and the outer concrete 

wall, or if the fuel has migrated beneath the tank, and if so, to what depth. 

The Navy intends to evaluate the performance of a pilot study to evaluate the effectiveness and 

feasibility of bioventing, soil vapor extraction, or other appropriate methods to reduce the 

volume of trapped product in-place, and if feasible, light non-aqueous phase liquid (LNAPL) 

removal from fractured basalt. Bioventing is being used at other Navy sites on Oahu with 

similar geology and is proven to be successful at reducing contaminant concentrations in both the 

vadose zone and groundwater.
