Operational Water Consumption and Water Riahts <br />A small amount of water will be required in mining operations to control dust and for <br />gravel washing. Water will be consumed in the enclosed crusher, screen plant and wash <br />plant, and through water sprays to keep dust down as needed. The wash plant will have <br />some settling ponds, which will have some evaporation, which is also considered a <br />consumptive use. Water will also be used to control dust on the access roads. If <br />necessary, dewatering shallow points are shown on MAP C. <br />Depletion from evaporation in gravel washing operations is estimated to be <br />approximately 500 gallons per day based upon previous experience. It is expected that the <br />gravel washing operations will be in operation a maximum of 52 weeks per year and 5 <br />days per week. With 1 acre-foot equaling 325,851 gallons, this would result in a <br />consumption of 0.4 acre-feet per year. <br />The daily consumption of water for dust control on the access road and pit is estimated to <br />be 12,000 gallons of water, or approximately 2 water truck loads. This would result in a <br />consumption of 9.6 acre-feet per year. <br />A total of approximately 10.0 acre-feet per year of water will be obtained utilizing the <br />land owners' (Stephen A. and Elaine C. Urie) water rights. <br />17
