West Elk Mine 2008 Annual Hydrology Report 25 <br />• 3.2 Spring and Seep Monitoring Program <br />Currently, there are 36 springs and seeps in MCC's hydrologic monitoring program (Table 5). <br />MCC added three new spring monitoring sites in the SOD mine plan area (96-2-2 Area Spring, <br />Deep Creek Spring 2, and Deep Creek Trail Spring) in WY 2007. The three new springs were <br />discovered in the fall of 2006 during routine monitoring outings in the Deep Creek drainage. The <br />spring monitoring stations were selected based on long-term continuous flow data records and on <br />projected mine development plans. <br />The spring and seep monitoring plan is divided into four general hydrologic categories for <br />discussion purposes: <br />o Springs and seeps in the North Fork drainage basin issuing from the strata above the F-coal <br />seam. <br />o Springs and seeps in the North Fork drainage basin issuing from strata in or below the F- <br />coal seam. <br />o Springs and seeps in the Jumbo Mountain area in the North Fork drainage issuing from <br />strata above the B-coal seam. <br />o Springs and seeps in the Dry Fork drainage issuing from strata above the E-coal seam. <br />• The locations of the spring and seep monitoring stations are shown on Map 2. The following <br />discussion of monitored springs is presented according to the general hydrologic categories <br />described above and is presented from upstream to downstream relative to the mining area. A <br />summary of the spring and seep monitoring program details is presented in Table 5. <br />• <br />June 2009 HydroGeo, Inc.
