West Elk Mine 2015 Surface Water and Groundwater Quantity and Quality Data Summary 22 <br />4.0 ADEQUACY OF THE MONITORING PROGRAM <br />MCC's hydrologic monitoring program operates in accordance with CDRMS Permit No. <br />C-1980-007, as revised by Technical Revision No. TR -88 and Permit Revision No. PR - <br />10. PR -10 includes a revised comprehensive hydrologic monitoring plan for the entire <br />permit area including the SOD mine plan area. A more detailed description of the <br />hydrologic monitoring plan is presented in Exhibit 71 in the permit document (CDRMS, <br />2006). <br />4.1 Mining Related Hydrologic Impacts <br />Since 1999, there have been no significant long-term adverse mining related hydrologic <br />impacts reported in surface water or spring resources in the western permit area, <br />specifically the Gribble Gulch area (WWE, 2001; HydroGeo, 2002; HydroGeo 2003; <br />HydroGeo, 2004; HydroGeo, 2005; HydroGeo, 2006; HydroGeo, 2007; HydroGeo, 2008, <br />HydroGeo, 2009, HydroGeo, 2010, HydroGeo, 2011, HydroGeo, 2012, HydroGeo, 2013; <br />HydroGeo, 2014, HydroGeo, 2015). Gribble Gulch was undermined from years 1995 to <br />1997; therefore, future long-term mining related hydrologic impacts in this area are not <br />anticipated. <br />In WY 2015 the West Elk Mine hydrologic monitoring program was conducted in <br />accordance with all permit requirements. The data collected in WY 2015 from sites in <br />the current monitoring program were adequate to assess potential mine -induced impacts <br />to the area's hydrologic system, with the exception of the damaged monitoring wells <br />listed previously. <br />During WY 2015, MCC operations were in compliance with Permit CO -0038776 limits <br />(Section 4.6.1). <br />June 2016 HydroGeo, Inc. <br />
