(ELI) has completed a geotechnical engineering exploration for the <br /> proposed landfill to be located approximately 12 miles southeast of Julesburg in Sedgwick County, <br /> Colorado. The site is located in the Northeast 1/4 of the Northeast 1/4 of Section 9 and the North <br /> 1/2 of the North 112 of Section 10, Township 11 North, Range 44 West of the Sixth Principal <br /> Meridian. The study was performed in general accordance with our proposal number D2093061 <br /> dated May 7, 1993. <br /> The results of our engineering study, including the boring location diagram, test boring records, <br /> laboratory test results and the geotechnical evaluation and discussion of laboratory test results <br /> relating to the design and construction of this project are attached. <br /> Three test borings were drilled to a depth of 50 feet at the locations shown on the Site Plan. The <br /> number, depth and locations of the borings as well as sampling depths were determined under <br /> your direction. The ground surface elevations of the borings were not determined. Laboratory <br /> testing was also performed under your direction and included moisture contents, dry densities, <br /> Atterberg limits, a moisture density relationship (standard Proctor) test, and a falling head <br /> permeability test. <br /> The borings were advanced with a truck-mounted drilling rig utilizing 6-inch diameter hollow stem <br /> auger. Continuous lithologic logs of each boring were recorded by the field geologist during the <br /> drilling operations. At selected intervals samples of the subsurface materials were taken by means <br /> of pushing thin-walled Shelby tubes or by driving split-spoon samplers. Representative bulk <br /> samples of subsurface materials were obtained from each boring. Penetration resistance <br /> Offices of The Terracon Companies,Inc.
