Hi Richard/Roxanne:

Attached are the updated information for the weekly progress report from Navy Region Hawaii, and the Fleet Logistic

Center Pearl Harbor for the week of June 17, 2014. In a process to ease reading, only sections with changes will be

annotated.

1. Preliminary Work Plan

A coordination meetings and siting of the sentinel wells were initiated. A site visit was conducted, and specific well

locations were determined based on drilling requirements, site topography, security, access, and archaeological sites.

The specific locations of Well 1 and Well 2 were submitted to DOH and HDR (groundwater model contractor) on 16 Jun

2014 for expedited review and approval. Approval received on June 17, 2014.

a. Item 1

‐ Models to estimate downward vertical migration of free product.

Funding for the vertical migration modeling (Phase 2) has been received and processed. An administrative modification

to the Basic Contract is pending.

2. Release Response Action Items (initiate immediately, complete as soon as practicable)

a. Action 1

‐ Provide a schedule for the ventilation of Tank 5 and an estimated date to commence the investigation

of release point(s) within Tank 5.2 Based on the latest results of nondestructive testing, at least seven defects in the tank wall have been identified. Testing

efforts are continuing.

b. Action 2

‐ The rate of vertical migration for the released JP

‐ 8 free product is unknown. Information from the

previously collected basalt cores could be used for initial modeling of vertical migration. This information is necessary to

protect drinking water resources from petroleum contamination. Prepare models for petroleum JP

‐ 8 releases of 10,000,

20,000 and 30,000 gallons from points at 25% intervals from the bottom to the top of Tank 5. Progress in developing

these models should be included in the preliminary work plan.

Previous borings and monitoring wells were installed in the lower access tunnel, which is located below the tank

bottoms. In the interest of time, initial models for vertical migration of contaminant mass will assume the geology

around the tanks is similar to the geology below the tanks.

As indicated in Item 1a above, funding for Phase 2 (Vertical Migration Modeling) has been received and processed. An

administrative modification to the basic contracting is pending.

c. Action 3

‐ Removal of petroleum free product from the area outside the tank will reduce downward migration of

the released JP

‐ 8 free product. Characterization of the free product plume and recovery of free product with increased

monitoring are required to address this plume.

d. Action 4

‐ Additional studies and procedures are required to address the potential and impact of any future

releases from the USTs within the Complex. This will require new financial and personnel resources to complete.

Funding for the preliminary work plan and all necessary following work is critical.

The draft Administrative Order on Consent was received from DOH on 13 Jun 2014 and is currently being reviewed.

Please feel free to contact me if you have any questions.

Vr,

Aaron
