e • water carriers. Mountain Coal Company owns water rights for these water sources. Mountain Coal Company may place portable stock tanks near the drill sites and maintain a minimum water ]evel in the tanks to insure water is available for stock and wildlife. This will reduce the risk of stock and wildlife approaching the mudpits for water. DRILLING ACTIVITIES Drilling activities for the proposed Exploration Drill ho]e will include mobilizing drill equipment to the sites, and drilling and setting approximately 40 feet of 6 inch casing into bedrock. The holes will be drilled with a 4 inch hole utilizing a wireline drill rig to retrieve a continuous core sample of the strata. The hole is planned to be drilled to a Beth SO feet below the B-Seam coal. Estimated total depth is 6 ] 0 feet. The hole will be logged for geophysical parameters following completion of drilling. Permeability and porosity tests may be conducted within the well bore at the completion of the geophysical logging. The hole is proposed to be completed as a water monitoring well with slotted screen section in the B-Seam coal if it is determined, after drilling, that the hole can be used as such. PVC and/or stainless steel pipe will be utilized. PROPOSED DRILL HOLE PLUGGING METHODS • The hole plugging methods described in 43 CFR II 3484.1(a) or Colorado Division of Minerals and Geology (CDMG) Rules and Regulations at 4.07.3, will be used for all holes at the end of the water monitoring well service period. It is anticipated that each hole will be plugged with cement from bottom to 50 feet above the uppermost thick coal seam and from 50 feet below to 50 feet above any aquifers encountered in the hole. The remainder of the hole will be filled with an approved completion mud, gel, cuttings, or cement to within 5 feet of the surface. The hole will be appropriately tabled. Surface casing will be cut off at or below the level of the soil surface. Currently, Mountain Coal Company plans to use the Exploration Hole as a groundwater monitoring site. RECLAMATION PLAN Reclamation activities of pads and roads will follow when it is decided by MCC that the drill holes are not performing their intended purpose. 1. Upon completion of each phase of activity at a given site, all debris, trash, and drilling related equipment will be removed from the site. 2. When the mud pit or pits are sufficiently dry, they will be filled with stored soil material and compacted to minimize any settling. 3. A backhoe and a bulldozer will redistribute material on and around the drill pad to achieve as closely as practicable the original contour of the site. The area will then be ripped or scarified.
