22TG3E3XC and 22TG4E4XC Sample Hole(s) Project Plan Minor Revision 328 Page 8 of II with a 0.5 acre drill pad and 10 year, 24-hour storm event and 1-ft of freeboard. Mud pit designs and calculations for 1.0 foot of freeboard have been previously approved by the CDMG. As the mud pits will be excavated into native soil, mud pit slope failure is not a concern. Water for the drilling operations will be pumped to the drill sites from the mine dewatering polishing pond using high-pressure hose in combination with frac tanks and high-pressure pumps. Mountain Coal Company, L.L.C. owns water rights for these water resources. DRILLING ACTIVITIES Drilling activities for the proposed methane drainage wells will include mobilizing drill equipment to the sites and drilling approximately 1,500 feet of 7-inch diameter casing into bedrock to a zone just above the coal seam. A depiction of a typical completed well sample hole will be forwarded to the CDMG along with the typical plug and abandonment diagram. Currently, MSHA is requiring monitoring and inspection of the wells twice daily after installation. It is anticipated the frequency of monitoring would decrease to a weekly monitoring and inspection of the installation. Routine maintenance will occur to the extent necessary, simultaneous with the weekly monitoring. PROPOSED DRILL HOLE PLUGGING METHODS In accordance with the Coal Program Guidance Document -Methane Drainage and Monitoring Wells, MCC will plug and abandon these MDWs per DMG Rules 2.05.4 and 4.07.3 at the minimum. A mechanical packer will be set at the Iowest possible point in the well (note that subsidence damage to the casing may preclude access to the entire depth of the casing). Above this packer the hole will be plugged with CDMG approved materials to the bottom of the 5-foot cement surface cap using tremmie line. The top 5- feet of the well below the sub-surface casing cut-off point (3-feet below the surface) will be plugged with a cement cap. The top 3-feet of the casing will then be cut off and the hole filled in with subsoil. A permanent mazker shall be installed on top of the plug identifying the well. The pad will then be reclaimed to approximate original contour. The Methane Drainage Well and other drilling experience for Mountain Coal Company has shown that no aquifers have yet been encountered. However, the procedures described above would serve to properly protect any aquifers that would be encountered. RECLAMATION PLAN Reclamation of the pad will follow when it is decided by MCC that the drill hole(s) aze not performing their intended purpose.
