Snow Gulch Mine, Togiak National Wildlife Refuge, Alaska

Description of Environmental Remediation Activities
BSI used helicopter and small boat support to provide innovative and cost saving technology to remediate contaminated soil at the remote Snow Gulch Mine, Togiak National Wildlife Refuge, Alaska. The site is a former gold placer mine active in the early 1900's and 1940s without road access. Project objectives were to remove contaminants from the site that included POL contaminated soil, asbestos containing material, lead contaminated soil, and to conduct a drum survey and crush 350 drums. However the transportation cost for removing the contaminated soil exceeded the available budget. BSI recommended using a mobile Hot Air Vapor Extraction (HAVE) system transported to the site via helicopter which would meet the client's budget. The HAVE system, owned and operated by Enzyme Technologies, Inc., included a remediation box with internal heating elements powered by a diesel fueled generator. A small excavator also transported by helicopter into the site, was used to dig soil and place it into the HAVE box. The soil contamination was recalcitrant heavy petroleum hydrocarbons in the residual range and heavy diesel range. The HAVE system effectively heated the soil to over 1,000 degrees Fahrenheit. Remediation sample results were non-detect. Asbestos abatement was completed on two wood heating stoves and old brake pads. The lead contaminated soil, lead sheathed cable, the ACM, asphalt/roofing tar, and batteries were removed from the site via helicopter and disposed of at appropriate facilities and documented in an RA report. BSI completed a survey of 850 drums by marking each drum and documenting the drum condition and potential contents. Three hundred fifty (350) empty drums were crushed on a lined containment area and left on site for future removal. All materials for disposal were shipped from the site via helicopter and then transferred to fixed wing transport to Anchorage for disposal. A draft remedial action report has been submitted to the client.

Description of Environmental Remediation Activities
Drained, pigged and inerted to abandon in place 17,360 lf of POL Pipeline. Drained and removed 14,310 lf of POL Pipeline and associated fueling hydrants, catch basins and metering pits. Performed 1,388 semi-quantitative headspace field screens to select 204 samples for analytical testing to assess all excavations for POL contamination. Segregated grossly contaminated soils based on field screening for remediation. Airport taxiways and aprons were repaired to original condition. Mr. Ward McDonnell was the Site Superintendent. Mr. Mark Greenough was the SSHO/QAQCSM and Mr. John Lambe, PE was the project engineer and project manager. This service contract project deviated from customary construction projects, in that the USACE Project Manager was comfortable with periodic inspections and did not feel the need for a full time Quality Assurance Representative. The project was delivered on time and within budget even with extensive differing site conditions. The client awarded additional Options for the 2004 Construction season, and modified the contract for additional investigative work for the 2005 Construction season.

FAA Woody Island Demolition, Kodiak, Alaska

Description of Environmental Remediation Activities
The original scope of work was to abate asbestos and remove lead based paint chips within then demolish seven FAA buildings. Selected buildings were burned to reduce the amount of demolition debris to be removed from the site. Building #600 was remediated for Leisnoi (Woody Island land owners) reuse. Debris was removed and disposed from several locations. Two fuel tanks and associated petroleum contaminated soil (PCS) were removed and disposed. Modifications to the contract included installing a new AST Tank at the Very High Frequency Omnidirectional Range (VOR) Building, transporting and disposing of non-hazardous and hazardous waste, additional PCS removal, and the addition of similar services at two additional sites at Shuyak Island and Lake Minchumina. The project was managed by Mr. Tim Finnigan with Mr. Ward McDonnell as his Site Superintendent.

Description of Environmental Remediation Activities
BSI/BNCI designed, built and installed a 300 CFM regenerative blower unit to aerate stockpiled DRO contaminated soil. The remediation system plan for this project consisted of an engineered ex-situ stockpile, constructed as a lined and covered biotreatment cell in which air flow, soil moisture, and nutrient levels can be controlled to optimize site conditions for microbial degradation of the diesel range organics. BSI/BNCI was responsible for determining the radius of influence, air permeability and biodegradation rate.

Service City Pad Site, 2002 Site Remediation, North Slope, Alaska

Description of Environmental Remediation Activities
This contract was administered by British Petroleum Exploration, Alaska (BPXA). This project included the excavation and placement of approximately 16,000 CY of petroleum impacted soil/gravel into onsite treatment cells. The project used competing technologies to determine the most efficient method for the bioremediation of gravels in an arctic environment (North Slope). Seven land farming cells were constructed and inoculated with different microbes, nutrients, and enzymes to determine which method presents the best biodegradation rate for the North Slope environment. This contract includes future work on additional orphan fund sites and several other non-orphan fund sites. The project is ongoing with BSI/BNCI working closely with BPXA, ADEC, and several other state agencies. The project is being managed by Mr. Greg Jarrell.

Combat Information Transportation System (CITS) Site Characterization, Eielson AFB, Alaska

Description of Environmental Remediation Activities
This was a Site Investigation project to characterize the horizontal and vertical extent of soil contamination at sites on Eielson Air Force Base, Alaska. During installation of a communications line at Eielson AFB, contaminated soil was found at five locations. BSI/BNCI was contracted to define the extent of soil and groundwater contamination at those five locations. The methodology to complete the site characterization included three steps: 1) soil gas sampling and analysis, 2) soil boring advancement and soil sample collection, and 3) groundwater monitoring well installation and sampling. Using a direct push drill rig, soil gas sample probes were advanced into the unsaturated zone. BSI/BNCI collected soil gas samples through the probes. The gas samples were analyzed on site using a portable gas chromatograph (GC) in a mobile laboratory for GRO/BTEX using GC methods AK101/EPA SW 8021 B. Results of the soil gas analysis were used to determine where to locate soil borings and groundwater monitoring wells. Monitoring wells were installed to determine groundwater flow direction and the presence of groundwater contamination. Soil and water samples were tested off-site at an approved laboratory. This project was managed by Mr. Greg DuBois.
