During 2012, we estimate that 81 million gallons of <br />water was transferred. This volume reflects the transfer of water that had collected in the sump <br />from sealed 4 West and 5 West Entries, sealed 13 West Entry, 4 north entry 1 fracture, motor <br />cooling water and dust control overspray. In addition, since the floor of the historic Somerset B <br />Seam Mine portal is at the approximate 6090' elevation, there remains approximately 33' of <br />elevation 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 338' borehole is uncased. The B seam <br />coal 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 2008, the sounder encountered more favorable conditions and a water level <br />appeared at the 6064' elevation. During 2008 the underground pumps ran very little. On October <br />12, 2008 the 13 West gate road was sealed, the Hubbard fan dismantled, the shaft sealed with <br />earthen materials and the western mining district sealed off. Pumping of water to D2B2 was also <br />concluded. The reclamation and seeding of the Hubbard fansite was completed in early 2012. <br />Date <br />D2B <br />Water Level (Elevation Ft.) <br />D2B2 <br />14 <br />
