(MCC) submits the enclosed Minor Revision application for the <br />drilling of up to two (2) drill holes, per entry, and wells to facilitate an intital monitoring/sampling <br />period, and then injection of water, foam, and nitrogen into a hotspot, if required, in the B Seam. <br />26 <br />Mountain Coal Company (MCC) is proposing to drill these wells in Section 1~, of T.135, R.90W, <br />6s'-Principal Meridian, Gunnison County, Colorado. The proposed project is within the current <br />permitted coal mining area (Permit Number C-80-007) and on land surface managed by the USFS. <br />The wells will be located on Federal Coal (BLM) Lease COC-056447. The well numbers are <br />24HG2E37XC A and B. The wells will be drilled in the area approved under TR-96 and subsequent <br />approvals for the annual operating plans i.e. MR-306 (2005), for Methane Drainage Wells. <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 Walls for Panels 16, 17, <br />17S, 18-24. ,The Forest Service performed an Environmental Assessment of MCC's Methane Drainage <br />Wells Plan, and approval was received in the Decision Notice and Finding of No Significant Impact, <br />May 31, 2002. Tkrese two proposed wells are in the overall project area but were not proposed for <br />inclusion in the US Forest Service reviews. As such, these wells are the subject of this separate <br />Mirior Revision. Because these wells are on US Forest Service managed lands, U5 Forest Service <br />approval of their installation will be required. <br />Use ~of mud pits on or near the drill pad excavated in native soil; Mud pit dimensions would be 30' x <br />30' x 8' to accommodate cuttings with 25% swell, the run-off associated with a 1-acre drill pad and <br />10 year, 24-hour storm event and 1-ft of freeboard. Mudpit designs and calculations for 1.0 foot of <br />freeboazd have been previously approved by the CDMG. <br />The attached Proposed MDWs and New Road Construction for 2005, Map 2, at a scale of 1" _ <br />1000', depicts the general location of the proposed drill pad, and proposed methane drainage wells <br />(part of the 2005 MDW Project). <br />
