5 I <br /> ,�a5�t3R��S <br /> RECEMIED <br /> �PI'�l�EER <br /> EXHIBIT AMUL <br /> 9. Detailed description of use and method of diversion: <br /> a. Evaporation from a maximum lake area of 17 acres <br /> will be 78.07 acre feet per year (17 acres times 4.59 acre <br /> feet per acre, gross lake evaporation) . The pit will be <br /> dewatered during mining operations, with the water being <br /> drained to a neighboring dry pit. This will not increase the <br /> evaporation losses from the pit; the evaporation will merely <br /> occur at another location. The dewatering will be <br /> accomplished by pumping at a maximum rate of 1500 gallons per <br /> minute. <br /> b. For the sixty days per year the pit may be <br /> operating, it is estimated that dust suppression requirements <br /> will be 10,000 gallons per day, or 1.84 acre feet per year. <br /> The water will be pumped from the pit at a maximum rate of <br /> 1500 gallons per minute. <br /> c. An estimated maximum of 100, 000 tons of product will <br /> be mined per year. Assuming a product moisture content of 4 <br /> percent, there will be a resulting water use of 2.94 acre feet <br /> per year associated with the product removed from the pit. <br /> d. The total water usage from all of the above listed <br /> activities will be 82.85 acre feet per year. <br />
