• for spring thaw periods and instances of strong rainfall events. Generally, the water discharged from <br />the pit will be lower in sediment than that which naturally flows in the River. Wetlands adjacent to the <br />pit will be watered during mining from the sediment sump. <br />There are no known problems with selenium in the underlying shale. <br />3. Water Consumption for the Operation and Water Rights <br />A small amount of water will be required to be used in the operation to control dust, wash gravel, and <br />losses incurred as a result of mining. The following is an estimation of the amount of water which will <br />be used for the operation. Water will be consumed in the enclosed crusher, screen plant and wash plant <br />through water sprays to keep dust down as needed. Since the mined material is wet, it is expected that <br />very little moisture will need to be added. The wash plant will have some settling ponds which will <br />have some evaporation which is also considered a consumptive use. Water may also be used to keep <br />dust down on the dirt portion of the access road leading to County Road 5. <br />is Depletions for moisture lost in the mined material has been calculated to be equal to the volume of <br />material mined below the water surface level. It is estimated that 200,000 CY of material will be mined <br />below the water table per year. It has been calculated that moisture will be lost in the mined material in <br />the amount of 10.3 acre-feet per month with a total of 124 acre-feet per year. <br />Depletions for evaporation from gravel washing operations have been calculated to be 500 gallons per <br />day based upon previous experience. It is expected that the gravel washing operations will be in <br />operation a maximum of 52 weeks per year and 5 days per week. This would result in a consumption <br />of 0.34 acre-feet per month with a total of 4.08 acre-feet per year. <br />Dust will be controlled by water as needed. Water will only be used to spot water roads when <br />conditions on the access roads and in the pit warrant the use of water to control dust. 2.0 acre-feet per <br />year will be allocated to dust control, or 0.17 acre-feet per month. <br /> <br />White River City Pit, January 09 G-4
