Joint Task Force Red Hill 

Spill Release Scenarios

Enclosure 2

Most Likely Release in LAT or HT Piping - Re-Packing/Un-Packing

4. Surface water will be inspected regularly to identify any sheen that might appear in the harbor

to allow for rapid response.

5. Vacuum trucks will be located at Hotel Pier and outside Adit 3 to quickly respond to any releases

at those locations.

6. Spill kits will be staged near the Adit 3 “Wye”, Adit 2, UGPH, and throughout the facility.

7. .

8.

Response Actions:

1. CRO immediately ceases defueling operations and shuts all Motor Operated Valves (MOVs),

limiting fuel spill to the volume in the pipe upstream of the rupture (144,29 4gallons).

2. A small size spill will likely pool in the vicinity of the rupture and will be cleaned up in the tunnel

by responders with absorbents and small portable pumps.

3. Fuel flow reaches the Lower HT and begins to be collected in the sumps. The 5plex Sump System

(1000gpm) in the Lower HT and the UGPH Sump System (280gpm) will pump the fuel directly to the

B-1 and B-2 Tanks at FLCPH FORFAC, 385,000gal capacity each.

Follow-up Actions:

1. Fuel and fuel residue remaining on the LAT/HT deck will be removed manually with absorbents

or small portable pumps.

2. Fuel in the FLCPH FORFAC Tanks will be removed by Vacuum Trucks or pumped elsewhere (i.e.

to Hotel Pier barges or other FLCPH tanks).

3. Fuel remaining in the fuel piping and will be unpacked and piping repaired.

Stakeholder Response Actions:

 Additional response actions are contained in the CNRH RHFSF Response Plan. Actions are

subject to modification pending HAZOPs finalized plan. Entities involved include, but are not limited

to: FEDFIRE, FLC, PORT OPS, USCG, EOC, JBPHH, and CNRH/ROC.

 Run temporary discharge piping or hose from the pumps to VS-1C to any desired product

pipeline(s), 

 Minor modifications to a line at the upper tank farm will allow pumping up to the UTF tanks

secondary containment areas, either to bladders or into the berms directly.

 Line the sides of the ramp with sandbags or other barricades that direct any oil that exits the

Adit 1 door into the lower yard tunnel. This oil will be picked up by the pumps (Fig 2,3).

PORT OPS (CNRH Spill Management Team)

 IAW TAB C - On Water Spill Containment and Recovery Strategies, RHTFSF Response

Plan.

QI/OSRO - QI will make necessary notifications, and contracted OSROs will respond within a reasonable 

amount of time with personnel and equipment that is previously identified and discussed in the 

contract.

USCG - The Federal On-Scene Coordinator Representative (FOSCR) attached to JTF Red Hill will be on call 

24/7 to offer expert advice and recommendations to facilitate a unified operational response. 

 The National Response Center will contact Sector Honolulu Incident Management

Division. If necessary, Pollution Responders and Federal On-Scene Coordinator

Representatives will be available to assist with facilitating divisional groups. The National

Strike Force coordination center will also be notified to determine if the Pacific Strike Team

needs to deploy assets to assist.

 Additionally, the Sector Emergency Management Force Readiness shop has the

capability to recall a Type I Incident Response Team from Sector Honolulu to implement the

Incident Command System and organize a Unified Command.

Additional response actions are contained in the CNRH RHFSF Response Plan. Actions are subject to 

modification pending HAZOPs finalized plan.

Discharge Analysis:

Most Dangerous Least Likely Discharge (4.3 million gallons)

The following is based on the most-probable worst-case discharge. In this scenario it is assumed the spill 

will be unsecured for approximately 6 hours. The analysis also assumes Adit 2 is sealed.

Without supplemental pumps from Navy SUPSALV, the only method for removing fuel from the tunnels 

would be the UGPH Sump Pumps 

 The total discharge from the tank will be 4,305,787 gallons based on engineering analysis 

conducted by PCCI. The product will reach Adit 1 in approximately 1 hour and begin to fill the entire 

space. The UGPH sump will send fuel to the B-1 and/or B-2 FORFAC tanks. Approximately 6 hours after 

the initiation of the rupture the fuel will overflow into the UGPH and begin spilling out of Adit 1. Over 

the next 18 hours: 1,049,187 gallons will spill out Adit 1 into the drainage swale and potentially impact

Enclosure 2

Most Dangerous Least Likely Discharge Scenario - Defueling

Halawa Stream, 

 

With four Navy SUPSALV supplemental pumps (Single capacity - 2,200 gpm; Total capacity - 8,800 gpm) 

in place, they can be utilized to move oil to the tanker vessels or the UTF containment. The following 

scenario is expected to occur: 

The total discharge from the tank will be 4,305,787 gallons based on engineering analysis conducted by 

PCCI. The product will reach Adit 1 in approximately 1 hour and begin to fill the entire space. The UGPH 

sump will send fuel to the B-2 FORFAC tanks; which has a 378,000 gallon capacity. Once the flow reaches 

their suctions, the SUPSALV pumps will direct flow to tanker vessels at Hotel Pier of the barges at Sierra 

Pier (both located on Joint Base Pearl Harbor). Roughly 7 hours after the rupture, a peak accumulation 

of 936,187 gallons is expected in the UGPH/Lower Harbor Tunnel. Due to the small gradient of the 

Harbor Tunnel the oil volume will cover the deck of the Lower Harbor Tunnel a few hundred feet past 

Adit 2 (sealed). It will not breach the UGPH Deck grating however, and it will not be discharged to the 

environment through Adit 1.
