-3- <br />• Total volume of water to be used on the existing and <br />expanded mine properties and at the tipple equals 105 <br />acre-feet per year (af/yr). This includes 2.2 of/yr of <br />water for dust suppression on the mine site, 0.3 of/yr for <br />dust suppression at the mine tipple, 0.6 of/yr for domestic <br />and commercial uses, 66.9 of/yr for storage in sedimenta- <br />tion ponds, and as much as 35 of/yr inflow to the mine <br />pits. The consumptive use of water on the mine site will <br />vary throughout the year, depending on the uses. The total <br />consumptive use of the mine is estimated to be 69.46 of/yr; <br />this is 66 percent of the water used on the property. Most <br />of the water consumed is in the filling of the dead storage <br />of the 14 sedimentation ponds. <br />• <br />CJ <br />Leonard Rice Consulting Waler Engineers, Inr,. <br />
