West Elk Mine • baseline data were collected and the wells aze now part of the regulaz monitoring program. Unfortunately, monitoring well 96-27-1 was rendered useless as a result of B Seam mining passed underneath and the well is not longer providing any data. Drill hole 96-15-1 was drilled during the 1996 exploration program and was completed as a water monitoring well in the B Seam. Because the well was venting a significant amount of gas, water measurement and sampling was precluded. The well has been fitted with a vent to allow de- gassing. In the event that the well discontinues producing gas, the well could be incorporated into the monitoring program. In 2001 and 2003, MCC drilled and constructed monitoring wells 01-11-1B in the B Seam and 03-11-1E in the E Seam, down-dip of the Box Canyon longwall panels. These wells were drilled prior to longwall mining of panel 18 (the northernmost Box Canyon panel) to assess potential down-gradient impacts and are currently being monitored. Five additional wells were constructed in 2003 to supplement the monitoring program of West Elk Mine. These included two alluvial/weathered bedrock wells in the Dry Fork of Minnesota Creek (Upper Dry Fork and Lower Dry Fork), two E Seam wells (one in the South of Divide permit revision azea (SOM-3E) and one down-dip of the Box Canyon Panels (03-11-1E)) and one B Seam well (SOM-3B), also in the South of Divide permit revision area. These wells are currently being monitored as part of the ongoing hydrologic monitoring program and will be addressed by the sepazate Technical Revision application previously referenced. Additional information about each of these monitoring wells (i.e., location, ground surface elevation, screened interval, and total depth) can be found in Table 4 of this report and Table 5 of the 2003 Annual Hydrology Report. 2.04 -60 Revised November 2004 PR/0
