Modification of Drill Holes to Surveillance for Water Levels <br />MCC proposes converting three of the exploration holes into ground water monitoring holes to <br />test for quantity and quality of ground water (if any). The proposed holes, depth of completion, <br />and seam or fomration to test are listed in Table 3. <br />Drill Hole Abandonment Methods <br />The drill hole plugging method described in 43 CFR II 3484.1(a) will be used for all holes not <br />otherwise being developed into ground water monitoring wells. Each hole will be plugged with <br />cement slurry through mineably thick coal beds and aquifers for a distance of at least 50 feet <br />above and below (see Figure 3). The rest of the bole will be filled with an approved bentonitic <br />completion mud or gel, cuttings, or cement to within 10 feet of the surface. A 10-foot surface <br />plug will be set, and a brass tag or monument marking the drill hole I.D. will be cemented atop <br />the surface plug. Surface casing will be cut off at or just below the level of the drill pad, <br />allowing for future location and identification of the drill hole. <br />Reclamation Plan <br />Reclamation activities will follow the completion of each hole as closely as possible. <br />1. Upon wmpletion of drilling activities at a given site, all debris, trash, and drilling related <br />equipment will be removed from the site. <br />Z. When the mud pit is sufficiently dry, it will be filled with stored subsoil material and <br />compacted to minimise any settling. All remaining subsoil will be redistributed on and <br />around the drill pad with a backhoe and/or bulldozer to achieve as closely as possible, the <br />original contour of the site. <br />3. Stored topsoil will be distributed as evenly as possible over the disturbed pad area <br />4. The entire drill pad area will be re-seeded using the following seed mix, which has been <br />approved by the USFS for drill sites in this area. <br />tz <br />
