22TG3E33XC and 22TG3E34XC Project Plan <br />tenor Revision 324 <br />Page 8 of 12 <br />CDMG. As the mud pits will be excavated into native soil, mud pit slope failure is not a <br />concern. <br />Water for the drilling operations will be pumped to the drill sites from the mine <br />dewatering polishing pond using high-pressure hose in combination with frac tanks and <br />high-pressure pumps. Mountain Coal Company, L.L.C. owns water rights for these water <br />resources. <br />DRILLING ACTIVI'T'IES <br />Drilling activities for the proposed methane drainage wells will include mobilizing drill <br />equipment to the sites and drilling and setting approximately 2,000 feet of 14inch surface <br />casing into bedrock to a zone just above the coal seam or into the third entry. The holes <br />will then be rotary drilled with a 12-inch diameter hole to the B-Seam and cased in <br />concrete to a 7-in diameter. A depiction of a typical completed well will be forwarded to <br />the CDMG along with the typical plug and abandonment diagram. <br />Currently, MSHA is requiring monitoring and inspection of the wells twice daily after <br />installation. It is anticipated the frequency of monitoring would decrease to a weekly <br />monitoring and inspection of the installation. Routine maintenance will occur to the <br />extent necessary, simultaneous with the weekly monitoring. <br />
