Subject: RED HILL STATUS REPORT - November 25, 2014

Importance: High

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 November 25, 2014. In a process to ease reading, only sections with changes will be

annotated.

1. Preliminary Work Plan

Action complete.

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.

Action complete.

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.

No change. Based on discussions/meetings with EPA and DOH, the need for vertical migration modeling for the JP

‐ 8

release is being re

‐ evaluated.

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.

Awaiting a written report on the free product investigation that will be incorporated into the tank 5 Characterization

WP/SP for release investigation under the tank.

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.

d.(1) Sentinel Wells

Preliminary analytical results for baseline groundwater samples from the two new wells, RHMW06 and RHMW07, are

expected in late November.2 d.(2) Site Characterization

No change. Site characterization beneath Tank 5 will follow completion of in

‐ tank product recovery efforts. See Update

for 2c

‐ Action 3, above.

d.(3) AOC/SOW

The Navy/DLA submitted the redraft of the SOW to EPA/DOH on October 31, 2014. A senior level discussion between

EPA, DOH, and CNRH/DLA was held on November 24, 2014. Negotiations are tentatively scheduled for the week of

December 8, 2014.

d.(4) Request for Additional Information

No change.

d.(5) BWS/USGS Groundwater Flow Study

No change.
