Sediment control will be placed and the water will be <br />conveyed as much as possible to a aew mud pit. The mudpit will be located on the existing pad and <br />constructed in subsoil. <br />The proposed typical well construction design, and plug and abandonment diagram are attached. The <br />plugging and abandonment of the well will be as follows: In accordance with the Coal Program <br />Guidance Document -Methane Drainage and Monitoring We11s, MCC will plug and abandon these <br />MDWs per DMG Rules 2.05.4 aad 4.07.3 at the millimum,•recognizing that due to subsidence, damage <br />to the casing may preclude setting a packer within 50-feet of the perforated, 7-inch casing. In such <br />cases the mechanical packer will be set at the lowest possible point in the well. A cement plug will be <br />installed with tremmie line beginning at the plug and preceding a minimum of 50-feet up the well. <br />From that point the hole may be plugged to within 5-feet of the casing cut-off point with approved <br />materials. The top 5-feet of the well below the sub-surface casing cut-off point (3-Feet below the <br />surface) will 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 identifying the <br />MDW. The pad will then be reclaimed to approximate original contour. <br />As shown on the well construction. design, the depth of this hole will be approximately 2,049 feet. <br />The Federal Coal lease affected is COC-56447. <br />The area has been previously disturbed. <br />
