~ III IIIIIIIIIIIII III <br />sr( EXHIBIT G ~~~~lb' <br />HATER INFORMATION <br />The Silt Pit property borders on the Colorado River <br />(see Map Exhibit C) and Divide Creek is the eastern boundary <br />of the site owned by the operator. Topographic maps indicate <br />several irrigation ditches running in a generally east to west <br />direction on the subject land. The ditches appear to begin at <br />Divide Creek. It is our understanding that the previous <br />owner pumped directly from the Colorado River for irrigation <br />purposes. There are no other waterways, canals, dams, <br />reservoirs or wells on the affected land. <br />The Silt Pit is to be decvatered by pumping settled water <br />to the Colorado River under an NPDES permit to be obtained <br />from the Colorado Department of Health. <br />It is estimated that under normal conditions the pit <br />will operate 250 days per year, 68 days of which are expected <br />to be summer days with dust suppression water useage at <br />20,000 gallons per day. The balance of 182 days will be <br />spring, fall and winter days with maximum water useage expected <br />to be 10,000 gallons per day. Thus, total water useage is <br />estimated at 3,180,000 gallons per year, or 9.76 acre feet <br />per year. <br />I In addition, the wash plant will handle approximately <br />1,000 gallons per minute. Most of the water will be returned <br />I to a settling pond and recirculated repeatedly. The operator <br />I estimates a water loss varying between 4 percent and 8 percent. <br />For the purpose of this estimate, the operator has used <br />_22_ <br />
