Subject: RED HILL STATUS REPORT ‐ MARCH 4, 2014

Roxanne/Richard:

Attached is information for weekly progress report from CNRH and NAVSUP FLCPH to DOH UST Section.  

1. Preliminary Work Plan (due Friday 14 March 2014)Preliminary Work

Plan:

a.  Item 1‐ Models to estimate downward vertical migration of free product.

There is a lack of models for investigating pure petroleum liquid.

However, we will continue to evaluate the availability of transport models in basalt.

b. Item 2 ‐ Methods or options for non‐invasive scanning of basalt to determine area and volume of contaminant mass

prior to any drilling investigation.

From our preliminary research, there are no remote sensing (geophysical) applications for non‐invasive scanning of

basalt to determine area and volume of contaminant mass.  There is too much noise and obstructions for approaches

such as seismic, ground penetrating radar (GPR), time‐domain reflectometry (TDR), thermal, etc.  The best quick and

dirty approach available for near surface contamination would be to use something like laser induced fluorescence (LIF)

with a direct push rig, but since basalt (competent or fractured) is the media, that approach won't work.  The usual

approach for differentiating/delineating the extent of contaminant plumes for saturated and unsaturated is by way of

intrusive methods.  It is likely that the only methods available to determine approximate area and volume of

contaminant mass are soil borings for soil and groundwater sampling.

c. Item 3 ‐ Methods and locations for borings to most efficiently characterize the extent of contamination.

A contract is being pursued to address Items 1 and 3 of the preliminary Work Plan.  The tank inspection may yield some

information of the location of the release.  The tank inspection will commence after Tank 5 has been vented.

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

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.

The most current schedule is as follows:

‐Contractor work plan approved by EXWC IOT commence preparation, venting, and equipment installation ‐ February25,

2014 ‐Contractor commenced mobilization ‐ February 27, 2014 ‐Contractor commenced venting preparations IOT stage

and install venting equipment ‐ February 28, 2014 ‐Venting commences ‐ March 20, 2014

‐ 

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 1.c above, contracted efforts are being pursued to characterize the situation.  These models will be

included with the contracted efforts for Item 1 of the preliminary Work Plan.

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.

As indicated in item 1.c above, contracted efforts are being pursued to characterize the situation.  During this contracted

effort, an assessment of the feasibility of product recovery will be accomplished and coordinated with the State

Department of Health.

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 Navy has submitted a funding request to the Defense Logistics Agency Installation Support Energy Environmental

Division (DS‐FEE) to cover updating the Red Hill Groundwater Protection Plan and to develop models estimating

groundwater flow and capture zones.  Planning estimates have been provided, and additional funding requests will be

submitted to DS‐FEE as statements of work and estimates are provided.

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