Analysis of the existing BC-1 data suggests no anomalies. <br />EC-14, EC-15 Wells -Elk Creek - Alluvium/Colluvium <br />The EC-14 well is. located up gradient of the EC-15 well. The EC-14 well is located in <br />undisturbed alluvium/colluvium up-gradient from the Elk Creek mine surface facility but down- <br />gradient from the eventual D seam mining area located in the upper reaches of Elk Creek. The <br />EC-15 well is located in alluvium/colluvium located south of the D seam portal area but north of <br />the coal stockpile area. Changes in the hydrologic condition of shallow Elk Creek alluvial <br />groundwater due Ito mining activities could potentially be monitored from these two wells. <br />During 2007, water levels in the wells were variable. The EC-14 and EC-15 lab samples were <br />obtained on June 19, 2007 and August 2, 2007 and the data suggests no anomalies. <br />Overall analysis of the very limited data for these wells suggest no anomalies. <br />D2B and D2B2 Mine Water Transfer Wells ("D seam to B seam") <br />The purpose of these two boreholes are to transfer mine water from the D seam Elk Creek mine <br />workings to the underlying Somerset B/C seam workings. The depth to water is to be measured <br />at the same frequency as the overall OMLLC groundwater monitoring program. Data is also to <br />be collected regarding 1) annual total volume of water transferred, 2) representative pH of <br />• transferred water and 3) representative TSS of transferred water. <br />D2B <br />The D2B mine water transfer well was drilled and completed in late December 2004 in the <br />vicinity of the upper Elk Creek facilities area. When the drill penetrated the B Seam workings, it <br />was apparent that this portion of the B seam mine was flooded with water. The B seam was <br />encountered at the 5918' elevation and a static water level later appeared at the 6042' elevation. <br />Water transfer operations first commenced in early 2005 in D2B. During 2007, the D2B water <br />meter indicated '74.9 million gallons of transferred water. This volume reflects the transfer of <br />water that had collected in the sump from sealed 4 West and 5 West Entries, motor cooling <br />water, dust control overspray and a short term flow of perched water inflow from the west end of <br />9, 10 and 11 West gate roads . In addition, since the floor of the historic Somerset B Seam Mine <br />portal is at the approximate 6090' elevation, there remains approximately 43' of elevation <br />remaining before the water could exit the mine at that location. <br />D2B2 <br />The D2B2 borehole was completed in December 2005 in the vicinity of the Hubbard Fan. Water <br />transfer started during early 2006. The bottom 39' of the borehole is uncased. The B seam coal <br />roof was encountered at 6046' elevation. After initial water transfer, initial water level was <br />encountered at 6053' elevation, or 7' above the coal. Subsequent measurements encountered an <br />apparent dry borehole obstruction at the 6070.7' elevation or 24' above the coal. The obstruction <br />has not precluded water transfer, but has limited the ability to lower the sounder past the <br />obstruction. During 2007, the sounder encountered sufficient moisture on the casing/ borehole <br />walls to render false readings as to the exact depth to any water level. During 2007 the <br />underground pumps ran about 30 minutes per week for an estimated flow to D2B2 of 312,000 <br />gallons. <br />13 <br />
