• 2.05.3 <br />During late 2008 a dewatering well approved through TR -53 was installed <br />in the D -Seam near the Mouth of Dove Gulch. Water from the well was <br />piped to the active B -Seam workings through the nearby ventilation shaft. <br />A pump powered by a diesel generator was installed in the well. A six <br />inch diameter water line was installed from the dewatering well to and into <br />the shaft. The 1,000 foot long water line was buried along the inside edge <br />of Hubbard Creek road. <br />Technical revision no. 52 provided for the installation of thirteen gob vent <br />holes over the next three years (2008 through 2011). MR -106 amended <br />the holes approved through TR -52 and added four additional holes. Since <br />the northeast mining district was essentially abandoned during 2009, only <br />nine of the seventeen the holes were drilled. <br />MR -92 provided for drilling GVB -8A -A during 2008. MR -100 provided for <br />drilling GVB -8A -B during 2009. Both holes are located on an existing drill <br />pad located near the mouth of Dove Gulch. <br />MR -105 provided for an additional gob vent hole GVB -8 -TG that was <br />installed during 2009 from a new drill pad located at the mouth of Dove <br />• Gulch. <br />TR-65 provides for a geotechnical hole to be drilled at a proposed shaft <br />site in Terror Creek. This hole will not likely be installed because the <br />proposed shaft in Terror Creek is to be moved to a more favorable <br />location. <br />MR -115 provides for the drilling of up to three geotechnical holes along <br />Terror Creek to select a site for a proposed shaft. <br />During 2012 eleven geotech holes approved through MR -88 will be drilled <br />west of the facilities area in a location identified as a potential coal mine <br />waste bank. <br />The expansion of the permit boundary to the west encompassed three drill <br />holes that were approved through Bowie No. 1 mine technical revisions. <br />Bowe -1 TR -41 approved BRL- 1 -03 -01 which was drilled in 2004. BRL -1- <br />03-01 may also be known as BRL- 04 -01. Bowie -1 TR-49 approved BRL1- <br />08-03 and BRL1- 08 -04. BRL1 -08 -04 was drilled in 2008. BR1 -08 -03 will <br />be drilled in two or three years (2012 to 2013). <br />PR-12 2.05-48- 2110 <br />
