Draft West Ells Mine 2005 Annual Hydrology Report 35 <br />• Panel 14 headgate E2 crosscut 34 <br />• Panel 14 headgate E3 crosscut 40 <br />A summary of the mine water quality is presented in Appendix H. <br />4.6 Mine Water Balance <br />The mine water balance was developed as a tool for water management to quantify the water <br />entering and leaving the mine. The WY 2005 mine water balance is summarized below and <br />illustrated on Figure 8. <br />Inflows (water entering the mine) include: <br />• Raw water intake (North Fork diversioti, "~ ac-ft) <br />• Mine Inflows (faults, coal outcrops, and drips, '~ ac-fr) <br />• Total Inflow = : ' ''° ac-fr <br />Outflows (water exiting the mine) include: <br />• Water in produced coal and GOB : ac-ft) <br />• Mine sump discharge and drilling water (~ ac-ft) <br />• Mine ventilation moisture (~ ac-ft) <br />• Miscellaneous mine seepage and evaporation ( ac-ft) <br />• Pond evaporation ac-ft) <br />• Runoff from surface operations\pond dischazge ac-fl) <br />• Total Outflow = "" ac-ft <br />The total volume of water entering the mine during WY 2005 was` ac-ft versus a total outflow <br />of _ ac-ft, a net difference of - ac-ft (surface operations discharge). <br />5.0 ASSESSMENT OF MINE-INDUCED HYDROLOGIC IMPACTS AND <br />ANTICIPATED IMPACTS IN WY 2006 <br />5.1 Surface Water <br />MCC maintains a network of 22 stream flow gauging stations throughout the permit and lease areas <br />(Table 2). The locations of the surface water monitoring stations are shown on Map 2. Daily mean <br />flow summary tables aze presented in Appendix A. Surface water flow hydrographs are presented <br />in Appendix B and the field and laboratory surface water quality data aze presented in Appendix C. <br />U <br />September 2006 HydroGeo, Inc. <br />
