Evaporative consumptive use <br />occurs during tailing slurry dispersion. In addition, a portion of the water that is in the slurry is <br />permanently bound to the tailing after the tailing is dispersed, and thereby effectively consumed. <br />Furthermore, the tailing impoundments themselves result in permanent, subsurface phreatic <br />zones, thus increasing water consumption. <br />4.1.4 Use of Water to Settle Out Tailing, in the Decant Water Pool. Eventually, <br />the flow from the tailing slurry dispersion enters the decant water pool on the tailing <br />impoundment, where the finest tailing particles are settled out. This significantly improves the <br />quality of the water that was used in the tailing slurry. Clarified water is then removed from the <br />top of the decant water pool and either discharged to Tenmile Creek after further treatment or <br />reused in the milling process. The decant water pool is necessary to settle out the finest tailing <br />particles and evaporative consumptive use is associated with this process. <br />4.1.5 Use of Water in Processine Waste Rock. The waste rock surrounding the <br />ore body at the Climax Mine Open Pit is primarily solid granite. New faces and fracture planes <br />in the rock are exposed as the rock is blasted, hauled, and deposited in the waste dump. These <br />surfaces are moistened through seepage of water into the Climax Mine Open Pit from Tenmile <br />Creek and its tributaries, by intentional wetting to control dust, and through seepage of run-off <br />water through the rock after it is placed in the dump. The portion of water that is permanently <br />bound to the surface faces of the waste rock is effectively consumed. <br />4.1.6 Evaporation Losses from Reservoir Storage. Storage of water in <br />• <br />Robinson, Buffehr, and Mayflower Reservoirs results in evaporative consumption of some of the <br />stored water. <br />56642. WPD:5 <br />
