C -- SOURCES OF SOIL REMEDIATION TECHNOLOGIES SOUGHT SOL KH900660 DUE 101599 POC Steve Heiman, (303) 966-7922 E-MAIL: Click here to contact the Subcontract Administrator, steve.heiman@rfets.gov. Kaiser-Hill Company, L.L.C.(Contractor), is the Integrating Management Contractor at the U.S. Department of Energy's (DOE), Rocky Flats Environmental Technology Site, Golden, Colorado (RFETS). The Contractor is currently planning the environmental remediation of the 903 Pad Area at RFETS. RFETS is located approximately 16 miles northwest of Denver, Colorado. The 903 Pad Area is comprised of the following three areas which are adjacent to each other: 903 Pad, 903 Lip Area, and the Americium Zone. The Contractor is interested in receiving information on proven technologies, equipment and methodologies that are applicable to the remediation of the 903 Pad Area. Remediation Area #1: 903 Pad (Individual Hazardous Substance Site 112) The area known as the 903 Pad was formerly used to store drums containing waste oils and chlorinated solvents contaminated with plutonium, americium and uranium (i.e., the 903 Drum Storage Area). Radionuclide-contaminated oil and solvents leaked from the drums into the surrounding soils. The drums were removed in 1968 along with approximately eight inches of contaminated surface soil. Clean fill and an asphalt pad were then placed over the remaining contaminated soils. The fill material overlaying the native soil ranges from 0.3 to 0.9 feet (average of 0.5 feet) in thickness. The asphalt pad is approximately 400 feet by 400 feet by 0.4 to 0.7 feet (average of 0.5 feet) thick and its surface is relatively level over its extent. Characterization work conducted in 1998 indicates the presence of radionuclide contamination in the asphalt pad, fill material, and native soil beneath the fill material. Contamination of the asphalt pad and fill material is suspected to have resulted from wind dispersion of contaminants from the 903 Lip Area. Detected activities for Pu-239/240, Am-241, U-233/234, U-235, and U-238, respectively, are as follows (all activities are in pCi/g and ND indicates non-detect): Asphalt Pad: 0.410 -- 1.22; ND -- 0.341; ND -- 1.33; ND -- 0.133; ND -- 0.919 Fill Material: 0.410 -- 558; ND -- 126; 0.728 -- 2.02; 0.029 -- 0.487; 0.844 -- 2.77 Native Soil: ND -- 152,000; ND -- 31,670; ND -- 178; ND -- 16.9; ND -- 780 Characterization work indicates the presence of low concentrations of volatile organic compounds in the native soils beneath the 903 Pad. These include detections of several regulated chlorinated solvents including tetrachloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCE) and carbon tetrachloride. Maximum detected concentrations for these solvents are 6.1 Parts per Million (ppm), 1.5 ppm, 4.4 ppm, and 1.5 ppm, respectively. Preliminary data suggest that up to 2,500 cubic yards (in place) of native soil beneath the 903 Pad and fill material are impacted by radiological contamination. The impacted soils cover an area of up to approximately 2.4 acres and range from 0.5 to 1.0 feet in depth. Remediation Area #2: 903 Lip Area (Individual Hazardous Substance Site 155) During the drum removal and soil cleanup activities conducted at the 903 Drum Storage Area in 1968, winds and surface water runoff transported contamination beyond the storage area, primarily to the south and east. This area, bounded by the interior access roads to the east and south, is designated as the 903 Lip Area. In 1970, approximately six inches of coarse road base was applied over the native soils in the 903 Lip Area. Targeted soil cleanup (removal) efforts were undertaken in 1976, 1978, and 1984 in which soils containing elevated levels of plutonium were removed from three different areas within the Lip Area. Radionuclide contamination in the fill material and native soils in the Lip Area remains, however. Characterization work indicates that plutonium 239/240 activities in fill and natural soils range from non-detect to 14,950 pCi/g. Americum-241 activities range from non-detect to 3,140 pCi/g. Uranium-233/234 activities range from non-detect to 35.8 pCi/g. Uranium-235 activities range from non-detect to 4.17 pCi/g. Uranium-238 activities range from non-detect to 75.7 pCi/g. Volatile organic compounds are not expected to be present in the 903 Lip Area. Preliminary data suggest that up to 10,000 cubic yards (in place) of 903 Lip Area fill/soil are impacted by radiological contamination. The impacted soils cover an area of up to approximately 6.7 acres and are, on the average, approximately one foot deep. Remediation Area #3: Americium Zone Area An area to the east of the 903 Lip Area, designated as the "Americium Zone," was also impacted during the drum and soil removal activities conducted in 1968 at the 903 Drum Storage Area. The Americium Zone is largely comprised of natural soils with the occasional presence of waste soil piles, concrete, and abandoned soil monitoring equipment. Characterization data resulting primarily from soil sampling and analysis and gamma spectroscopy surveys indicate the presence of the following radionuclide contamination in the Americium Zone. Plutonium-239/240 is estimated at activities up to 829 pCi/g (see below). Americum-241 activities range from non-detect to 115.74 pCi/g. Uranium-233/234 has not been detected in the Americium Zone. Uranium-235 activities range from non-detect to 0.575 pCi/g and Uranium-238 activities range from non-detect to 11.354 pCi/g. It should be noted that plutonium was not directly detected in the Americium Zone (the Pu-239/240 detection limit for direct survey measurements was 2,500 pCi/g). The maximum plutonium activity listed above is conservatively estimated from detected americium activities using an Pu-239, 240/Am-241 activity ratio of 7.16. Volatile organic compounds are not expected to be present in the Americium Zone. Preliminary data suggest that up to 7,820 cubic yards (in place) of 903 Lip Area fill/soil are impacted by radiological contamination. The impacted soils cover an area of up to approximately 9.7 acres and are up to six inches deep. Geology and Topography: Native soils under the 903 Pad and in the 903 Lip Area and Americium Zone are primarily clays and gravel (e.g., gravelly clays, sandy clays, clayey gravel, etc.) with large cobbles (up to six inches) and large/rocks and boulders (up to two feet). The portion of the 903 Lip Area to the east of the pad is relatively flat. The area to the south and southeast of the pad slopes from the northwest to the southeast at an average grade of approximately 0.15 feet/feet. The topography of the Americium Zone varies from flat to gentle slopes to relatively steep hillsides. Information Packet: A packet containing additional site background information on the 903 Pad, the 903 Lip Area, and the Americium Zone is available upon request. The packet includes detailed information on the historical use of the site and resulting contamination, topography, geology, and hydrology as well as site characterizations, treatability studies and removal actions conducted to date. The information packet also includes scaled maps of the three areas in question that illustrate the areal extent of contamination and topography. Contact the point of contact listed at the beginning of this advertisement to request a copy of the information packet. The information packet will be sent to those requesting it by regular mail. Source Identification: As part of a market survey, the Contractor is requesting technical and operational information regarding technologies, equipment, and methods that are applicable to the remediation of the 903 Pad, 903 Lip Area, and Americium Zone. Technologies of interest include, but are not limited to, soil removal/excavation, handling, conveyance, and transportation as well as in situ and ex situ soil stabilization technologies that would effectively reduce the mobility of radiological contaminants present in soils that may remain in the environment. Stabilization technologies such as capping, solidification, vitrification, etc. must significantly reduce the potential for the contaminants to migrate from the impacted areas via wind and surface water transport, and must minimize further translocation of these contaminants into subsurface soils. The Contractor is also interested in waste minimization technologies. Specifically, technologies and processes that will minimize the volume of 903 Pad, 903 Lip Area, and Americium Zone soils that must be disposed in a regulated landfill. Such technologies include, but are not limited to, size reduction, soil segregation, soil washing, attrition scrubbing, and compaction. Technologies that enhance the precision of soil excavation/removal efforts, and thus, minimize the potential for over-excavation while achieving remediation targets are also of interest. Because of the presence and magnitude of the radiological contamination, the Contractor is interested in technologies and equipment designs that significantly minimize the generation of dust and dust emissions during soil removal, transfer, handling, processing, and containerization activities as well as other remedial field activities. Information shall include, but not necessarily be limited to: technical specifications, equipment drawings, process flow-sheets, statements of qualifications, similar project experience descriptions, operating performance data, and dust generation/emission data. Due to the nature of this remediation work, the Contractor is interested in proven technologies, equipment, and methods for removing/excavating, transporting/conveying, stabilizing, and processing (for the purpose of waste minimization) soils contaminated with elevated levels of hazardous and radionuclide constituents. .
