• Bathhouse Consumption <br />The bathhouse has been razed and therefore no water usage for bathhouse consumption is <br />included in this calculation. <br />Ventilation Fan Moisture Output <br />The ventilation fan has been removed and therefore no fan moisture output is included in this <br />calculation. <br />In summary, the Bowie No. I Mine is expected to consume: <br />Item Acre-Feet <br />Road Dust Suppression 2.2 <br />Pond Evaporation 2.6 <br />Underground Dust Suppression <br />Continuous Miner(s) 0.0 <br />Underground Roadways 0.0 <br />Conveyor Sprays 0.0 <br />Conveyor Sprays -Surface 0.0 <br />Bathhouse/Domestic 0.0 <br />Total estimated consumptive use 4.8 <br />The estimated water depletion from the Bowie No. 1 Mine was last evaluated in 1994 when the <br />mine planned to increase production to 1.5 million tons per yeaz (Ref Volume 9A, Tab-Fish and <br />Wildlife). The operator estimated the following depletion for a production rate of 1.5 million tons <br />per yeaz: <br />Item Acre Feet/Yeaz Basis <br />Mine Consumption 28.7 1.5 Million tons/yeaz <br />Surface Consumption 30.9 1.5 Million tons/yeaz <br />Pond Evaporation 4.6 1.47 acres of ponds <br />Total Consumption 64.2 <br />The consumptive use is therefore reduced by 59.4 Acre-Feet by TR-35, from the 1994 estimated <br />water depletion. <br />I• <br />MR-Io8 <br />/i PPRovE0 <br />6/iq/dy <br />
