E 2 through E 12 Longwall Panels Methane Drainage Wells Project Plan <br />PR-14 <br />Page 13 of 13 <br />depth of the casing). Above this packer the hole will be plugged with CDRMS approved <br />materials to the bottom of the 5-foot cement surface cap using tremmie line. The top 5- <br />feet of the well below the sub-surface casing cut-off point (3-feet below the surface) will <br />be plugged with a cement cap. The top 3-feet of the casing will then be cut off and the <br />hole filled in with subsoil. A permanent marker shall be installed on top of the .plug <br />identifying the MDW. The pad will then be reclaimed to approximate original contour. <br />The Methane Drainage Well drilling experience for Mountain Coal Company has shown <br />that no aquifers have yet been encountered. However, the procedures described above <br />would serve to properly protect any aquifers that would be encountered. <br />A drawing of a typical abandoned MDW is attached as Figure No.3, Proposed MDW Hole Plugging <br />Method. Anticipated total depths for these wells range from 550-feet for MDWs E 2-5.5 ; and <br />approximately 1400 for MDW E 4-82. <br />4. Retention of drill logs by applicant. <br />MCC will retain in its files all drill logs and will make them available for inspection by <br />any authorized officer. MCC may conduct geophysical logging and/ or collect core from <br />this project. <br />5. Utilizing drill holes as water monitoring wells. <br />MCC does not anticipate encountering any significant aquifers during this drilling <br />program. MCC does not intend to complete any of these holes as water monitoring wells. <br />6. Maps of Project Area <br />The attached E Seam MDW Drilling map at a scale of 1" = 800' depicts the general <br />locations of proposed drill pads, methane drainage wells, and USFS low volume roads. <br />This map also shows the proposed MDWs in relation to the land ownership, mine permit <br />and lease boundaries and other mine features. <br />7.
