• 2.04.11 <br />The train loadout system has one spray system. Approximately 600 <br />trains will be loaded per year based on 6.0 million tons per year. <br />Each train is loaded in 2 hours or less. <br />• <br />Spray System details <br />Spray Details <br />Consumption per system - 2 hour trair <br />1 Spray System <br />Consumption -acre feet for 600 trains <br />3 Sprays <br />1.6 gpm/spray <br />576 gallons <br />576 gallons <br />1.1 <br />In summary the Bowie No. 2 Mine is expected to consume: <br />Item <br />Road Dust Suppression <br />Pond Evaporation <br />Underground Dust Suppression <br />Longwall <br />Continuous Miner(s) <br />Conveyor Sprays <br />Underground Roadways <br />Conveyor Sprays -Surface <br />Reclaim Tunnel Spray -Portal Bench <br />Reclaim Tunnel Spray -Lower Coal Stockpile (Same as portal) <br />Unit Train Loadout <br />109.3 <br />27.2 <br />12.6 <br />6.5 <br />62.8 <br />6.5 <br />6.5 <br />1.1 <br />12.5 <br /> <br />PR-06 <br />/9 P~ROV6.D <br />~~/5~02 <br />Bathhouse/Domestic <br />Total estimated consumptive use <br />Acre-Feet <br />8.9 <br />3.0 <br />256.9 <br />At 5.0 million tons per year the mine was expected to consume 236.6 acre <br />feet. Increasing the production to 6.0 million tons and adding the unit train <br />loadout will increase the estimated depletion of flow from the upper Colorado <br />River Basin by 20.3 acre feet (256.9 - 236.6).
