Based on the tailings distribution to the upper and <br />. lower disposal areas shown in the lower right quadrant, the <br />tailings levels will become equal at an elevation of 8,564 ft <br />at year 1.8. <br />The upper left quadrant shows the elevation of the <br />tailings disposal areas as a function of time. The lower left <br />quadrant is the instantaneous slope of the above curves and <br />represents the instantaneous rate of rise of the disposal <br />area(s). <br />The curves in the lower left quadrant indicate that the <br />initial rate of rise in the lower disposal area will be 40 <br />ft/year while the initial rate of rise in the upper disposal <br />area will be 17 ft/year. At elevation 8,564 where the <br />elevations are equal, the rate of rise of the disposal area <br />will be 12.5 ft/year. Above elevation 8,590 ft where deposition <br />of tailings occurs in a single disposal area, the rate of rise <br />• is 8 ft/year or less, decreasing to 1 ft/year at year 7.5. <br />D.6.7.3 Water Recvclina <br />All water used in the milling process wil'' be recycled <br />to the extent possible. During operations, a free water pool <br />will occur on the tailings disposal area as the tailings <br />settle. The collection pond water will also be pumped to the <br />free water pool. Based on the water balance presented in <br />Section D.7, a maximum of 50 acre-ft of water covering an area <br />of approximately 20 acres or less will be maintained in the <br />free water pool. The water balance of the tailings disposal <br />operations is described in Section D.1. <br />To facilitate return of water to the process during <br />Phase I operations, two floating intakes and skid-mounted pump <br />stations will be operated from access ramps located on either <br />• side of the splitter embankment. Access ramps are shown on <br />D-55 <br />
