- 24 - <br />u <br />C~ <br />• <br />using coring equipment if large sandstone boulders would be <br />encountered, and in the bedrock. The boring would be care- <br />fully sampled so that a sufficient number of samples of the <br />fill material could be obtained. An attempt would be made to <br />obtain also samples of the soils below the fill and of the <br />underlying bedrock. <br />Three additional borings would be located below the toe <br />of the crushing and screening level fill. Two of them would <br />be used for the installation of the monitoring wells; one of <br />them would be located directly below the toe of the fill. The <br />purpose of the borings below the toe of the fill is to .: <br />obtain samples for the testing of physical properties of <br />foundation material. It is also necessary to obtain suf- <br />ficient data on the conditions of the Mancos Shale that is <br />present at this location. <br />Two of these borings will be used for the installation <br />of monitoring wells as discussed in the next section. <br />Two additional borings would be located at the diversion <br />channel cut; they would provide data on the depth of the <br />buried channels and the character of the soils. They would <br />also assist in the evaluation of whether a landslide may <br />exist at this location. <br />A series of six to eight test pits would be excavated <br />and backfilled during the Phase 2 work (a backhoe would be <br />used for this purpose). Two test pits would be excavated at <br />the diversion ditch cut to verify the geologic conditions <br />on the soil-rock contact within the cut. The remaining test <br />pits would be used for the verification of material propertie <br />of the fills on the site. <br />GFOXYOQO CONMfN1G, INC. <br />
