11) The portable enclosed crusher and screen plant do use sprays for dust control, although the <br />gravel will be somewhat wet after excavation from below water level, and the need for <br />additional water in the operation will be minimal. Estimated use for the crusher/screen plant is <br />2% of the annual tonnage run through the plant, approximately 52,000 tons per year. This <br />results in an additional consumptive use of .85 Acre-Feet per year. Pond evaporation is <br />estimated at 9.37 Acre-Feet per year. <br />12) A seven foot (7') overburden berm will be used along the boundaries of the pit to isolate water <br />on and off the property. The slopes of this berm will be 3HAV. The irrigation ditch north of the <br />access road and the stockpiled overburden berm will prevent any water from entering the <br />property. The area North of the permit area drains away from the pit and no undisturbed water <br />can enter the permit area in these locations. Since the operation involves pure excavation of <br />the resource, all water from the pit areas and facility areas will be detained within the permit <br />boundary for the 100 year event. <br />We hope this addresses DRMS concerns.
