Water will be used in a number of ways in the pit operation: <br /> 1)Control dust on the haul roads and excavation areas <br /> Water used for dust suppression is usually 100 percent depletive with no measurable return flows <br /> to the river system Dust from the haul roads will be controlled by water. Water will only be <br /> applied when needed at this elevation,since cold conditions on site for much of the year result <br /> in little evaporation and/or dust. It is assumed that watering of roads will require 1700 gallons <br /> water Ix per day for 30 days per year. Other days will have natural moisture on the roads, or the <br /> site will be inactive since the annual production is not very high. <br /> 2)Crushing and Screening Plant Operations <br /> The crushing/screening plant uses 200 gallons per hour at a throughput rate of 225 tons per hour, <br /> but 180 tons per hour will be assumed,so this amount for 180 tons per hour is conservative. <br /> Therefore,the total hours needed per year to produce the required tonnage is 223 hours.The <br /> crusher will be an enclosed crusher with water sprays and the screen deck will also have sprays <br /> at the entrance and on the screen deck itself_This is an amount of 44,445 gallons per year which <br /> is equivalent to 12 4,000-gallon water truck loads delivered to the site per year. <br /> SOILS INFORMATION <br /> The soil survey performed by the NRCS covers the permit area. <br /> There currently very little usable topsoil in the mine site as the operation limits are within a <br /> weathered gravel knob. The landowner at the end of the project might elect to import topsoil <br /> from other areas of their property to make the site productive farm ground. <br />
