Bryson Twidwell
1/1/1992 Site Added to Database PCB, BTEX, lead and chlorinated solvents contamination. Bryson Twidwell
10/1/1992 Site Characterization Report Approved (Old R:Base Action Code = SA1R - Phase I SA Review (CS/LUST)). ADEC's contractor for the site assessment was Shannon and Wilson. Shannon and Wilson conducted borings, installed several monitor wells, sampled all of the old and new monitor wells, took soil samples of all the borings, took water and sediment samples from the open pit. Shannon and Wilson found several new areas of contamination from reviewing aerial photographs and doing soil borings in suspicious areas. A fence was placed around the contaminated areas in December 1991. Shannon and Wilson's greatest concerns are the following conclusion from their data: "The covered pit at the site has been used to dispose of miscellaneous debris as well as a drain field for wastes that are discharged into a metal grate located between Hydro test and the concrete slab. The metal grate is connected to the covered pit by a 6 inch steel pipe. Elevated concentrations of petroleum hydrocarbons, chlorinated solvents and hazardous substances at the site were found in the sump box below this grate and in the soils surrounding this grate. The highest levels of contaminants, however, were encountered at the discharge end of the effluent pipe covered pit. Several new areas of oil stained soils as well as where tanks and drums were stored in the past was visible in the aerial photographs acquired during this assessment. the unconfined groundwater table, with static levels at about 35 feet below the surface is in our opinion apparently being recharged by surface water collecting above and infiltrating downward through the covered and open disposal pits. The soils are relatively permeable beneath the disposal pits and provide little resistance to the downward migration of fluids. The continuous boring showed highly permeable soils adjacent to the pit. The bottom of the pit may be lined with emulsified petroleum or fine grained drilling muds. However, we feel that this artificial lining of the bottom of the pits will only cause infiltrating water to migrate laterally until in contact with more permeable soils and then continue on its downward decent."

11/20/2009 Document, Report, or Work plan Review - other Reviewed and approved the Focused Site Investigation Work Plan, dated November 13, 2009, from ALTA Geosciences, Inc. The proposed work will reflect the current site conditions and the concentration of the contaminants present at the site. Two test pits will be excavated within the Covered Pit Area, and two samples will be analyzed from each of the test pits. Four test pits will be excavated within the Open Pit Area, and one sample will be analyzed from each of the test pits. Also proposed are two test pits to be excavated within the Outside Grate Area, and four samples will be taken from the two test pits. The areas of the Machine Shop and the Drill Shop Sump will not be evaluated within this Work Plan due to the small volume of potentially impacted soils, which are unlikely to affect the feasibility of the capping option that is being proposed. Paul Horwath
11/2/2010 Document, Report, or Work plan Review - other Reviewed the Focused Site Investigation Report, Former Coastal Drilling Site, from ALTA Geosciences, Inc., dated September 2010. The investigation efforts of the open pit indicated that the pit consists of mostly uncontaminated solid waste other than in the northeast side of the pit where several vehicle batteries and battery parts were found, and hydrocarbon-saturated soils at a depth of 10 feet with 9,650 mg/kg DRO and 323 mg/kg GRO. The total volume of the open pit is estimated at 550 cubic yards. The investigation efforts of the covered pit indicated that the area near where the drain pipe from the grate area had discharged, an elevated DRO concentration was detected at 1,240 mg/kg. The measurement results of the density of the cover material over the covered pit indicated that the soils consist of silty sand with gravel with a maximum density at 130 pounds/cubic feet, and a relative compaction of 92.8%. The investigation efforts of the shallow soils in the grate area indicated that PCBs were detected at low levels that were below the ADEC soil cleanup levels. Alyce Hughey
