. Depletions <br />Two scenarios exist for depletions: <br />1. During Mining <br />During the mining phase, losses will occur in three azeas: <br />Depletions for moisture lost in the mined material has been calculated to be 4% of the material <br />mined below the water surface level. It is estimated that 175,000 tons of material will be <br />mined below the water table per year. Assumptions are that mining will occur year round for a <br />fifty-yeaz mining period. It has been calculated that moisture will be lost in the mined material <br />in the amount of 0.28 acre-feet per month with a total of 3.36 acre-feet per yeaz. <br />Depletions for gravel washing operations have been calculated to be five-hundred gallons per <br />. day based upon previous experience. It is expected that the gravel washing operations will be <br />in operation a maximum of fifty-two weeks per yeaz and five days per week. This would result <br />in a consumption of 0.34 acre-feet per month with a total of 4.08 acre-feet per yeaz. <br />Dust will be controlled by both magnesium chloride and water. Water will only be used to spot <br />water between applications of magnesium chloride in order to eliminate any problem dust <br />azeas. 3.0 acre-feet per yeaz will be allocated to dust control, or 0.25 acre-feet per month. <br />Total annual depletions from the gravel mining operations aze estimated to be 10.44 acre-feet <br />per yeaz during the mining phase. <br />2. After Mining <br />Once mining has completed, the only loss will be an evaporative loss from the exposed water <br />surface which the gravel mining operation creates. As indicated in the reclamation plan, the <br />. size of the lake will vary depending on the size of the island that is constructed. If the <br />Anderson Pit, Apri107 G-4 <br />
