Methane Drainage Wells Project Plan <br />Technical Revision 103; MDWs 20-04, 20-05, 21-05, 2t-06 <br />Page 2 of 12 <br />DRILL HOLES 20-04, 20-05, 21-05, 21-06 PROJECT PLAN (26-Jul-05) <br />Technical Revision Number 103 <br />PROJECT DESCRIPTION <br />The proposed project consists of drilling four (4) methane drainage wells (MDWs 20-04, 20-05, <br />21-05, and 21-06) to facilitate mining in the B Seam. The proposed wells aze in Section 14, of <br />T.13S, R.90W, 6a' Principal Meridian, Gunnison County, Colorado. The proposed project is <br />within the current permitted coal mining area (Permit Number C-80-007) and on land surface <br />managed by the US Forest Service. The holes are on Federal Coal (BLM) Lease COC-056447. <br />The US Forest Service is the land surface owner for the drill sites and the associated access <br />roads. <br />MCC's overall plan for drilling and reclaiming MDWs was originally approved by CDMG on 15 <br />July 2002 as Technical Revision 96 -Project Plan for Methane Drainage Wells for Panels 16, 17, <br />175, 18-24. The Forest Service performed an Environmental Assessment of MCC's Methane <br />Drainage Wells Plan, and approval was received in the Decision Notice and Finding of No <br />Significant Impact, May 31, 2002. The proposed MDWs (20-04, 20-05, 21-05, and 21-06) are part <br />of this overall project but the decision approving their construction was deferred. As such, these <br />wells aze the subject of this separate Technical Revision. Because these wells are on US Forest <br />Service managed lands, a US Forest Service review of their installation is also required. <br />The attached "Technical Revision 103 MDWs 20-04, 20-05, 21-OS and 21-06" map at a scale of <br />1" = 800' depicts the general locations of proposed drill pads, methane drainage wells, and the <br />new road. This map also shows the proposed MDWs in relation to the land ownership, mine <br />permit and lease boundaries and other mine features. <br />SURFACE TOPOGRAPHY <br />The elevations of the proposed borehole location aze 6850 feet (ASL) for MDWs 20-OS and 20- <br />05; and 7150 feet (ASL) for 21-OS and 21-06. The terrain is comprised of steep slopes and mesa <br />tops formed within the Wasatch and Mesa Verde Formations and the colluvium and alluvium <br />layers of the slope debris. The principle drainage in this azea is Box Canyon, a tributary to the <br />North Fork of the Gunnison River. <br />GEOLOGY <br />The proposed Project would include drilling along the southeastern edge of the Piceance Basin <br />within the Somerset Coal Field, occurring on the Somerset U.S.G.S. 7 1/2-minute quadrangle <br />map. <br />
