<br />24HG Sample Hole(s) Project Plan <br />Minor Revision 321 Revision <br />Page 2 of 12 <br />I • <br />PROJECT DESCRIPTION <br />The proposed project consists of drilling up to two (2) holes, per entry/crosscut, and wells <br />to initially facilitate monitoring/sampling, and then injection of water, foam, and nitrogen <br />into a hotspot, if required, in the B Seam. One of the proposed drill holes is intended to <br />serve as an inlet for jet engine exhaust, which will serve to inert the mine atmosphere. <br />The other six proposed wells might be used to construct temporary seals if the jet engine <br />exhaust fails to inert the atmosphere as anticipated. The proposed wells are in Section 22, <br />of T.13S, R.90W, 6`h Principal Meridian, Gunnison County, Colorado. The proposed <br />project is within the current permitted coal mining area (Permit Number C-80-007) and <br />on land surface managed by the USFS. The wells will be located on Federal Coal (BLM) <br />Lease COC-056447. The well numbers are 24HG1E11.SXC A and B, 24HG2E11.SXC <br />A and B, 24HG3E11.SXC A and B, and 24HG2E12XC (the jet hole). The wells will be <br />drilled in the area approved under TR-96 and subsequent approvals for the annual <br />operating plans i.e. MR-306 (2005), for Methane Drainage Wells. Another minor <br />revision No. 319 was approved for 24HS01 through 24HS03. <br />MCC's overall plan for drilling and reclaiming MDWs was originally approved by <br />CDMG on 15 July 2002 as Technical Revision 96 -Project Plan for Methane Drainage <br />• Wells for Panels 16, 17, 175, 18-24. The Forest Service performed an Environmental <br />Assessment of MCC's Methane Drainage Wells Plan, and approval was received in the <br />Decision Notice and Finding of No Significant Impact, May 31, 2002. These proposed wells <br />are in the overall project area but were not proposed for inclusion in the US Forest Service <br />reviews. As such, these wells are the subject of this separate Minor Revision. Because <br />these wells are on US Forest Service managed lands, US Forest Service approval of their <br />installation will be required. <br />The attached Proposed MDWs and New Road Construction for 2005, Map 2, at a scale of <br />1" = 1000', depicts the general location of the proposed drill pad, and Project methane <br />drainage welts, and the new road (part of the 2005 MDW Project). <br />SURFACE TOPOGRAPHY <br />The elevations of the proposed borehole locations range from approximately 7300 ft to <br />7200 ft. The terrain is comprised of steep slopes and mesa tops formed within the <br />Wasatch and Mesa Verde Formations and the colluvium and alluvium layers of the slope <br />debris. The principle drainages in this area are unnamed tributaries to Deep Creek that is <br />tributary to Raven Creek that is tributary to the North Fork of the Gunnison River. <br />
