Sufficient overburden to be used for reclamation <br />will be stockpiled on the southerly end of the pit. <br />EXHIBIT D - Wildlife, Water, vegetation, Soils <br />it is not anticipated that free groundwater will be <br />encountered. Ground water is actually irrigation which has <br />penetrated through the silty surface soil, run to the bottom of <br />the gravel, and is located at the interface between the gravel <br />and underlying shale bedrock. This water expresses itself as <br />seeps at the exposed edges of the cross-section at the 32 Road <br />cut, the C 1/2 Road cut and at the palisade overlooking the <br />Colorado River. <br />One foot of gravel will be left in the pit bottom to allow seep <br />water to continue through it's traditional system and not draw <br />into the replaced overburden by capillarity. This will allow <br />irrigation of the site without accumulation of "alkali". A toe <br />trench at the base of the backslope will intercept any seep <br />from higher in the formation. <br />The pond presently on site is approximately 1/2 acre in size <br />and roughly five feet deep. It is filled by waste water from <br />irrigation runoff and seep water. <br />Runoff from the pit area will be impounded by leaving a one <br />foot high berm between the drainage and the pit floor. Annual <br />precipitation in the Grand .TUnction area is about eight inches <br />per year. It is anticipated that the small amount of water <br />impounded will evaporate or permeate into the gravel left on <br />the pit floor. <br />
