7. The access roads will be restored as closely as possible to the approximate <br />original contour, re-seeded, fertilized, and mulched as above. An temporary <br />seed mix as approved by the USFS may be used to accommodate an <br />intermediate seeding to help prevent erosion or sedimentation on road cuts and <br />fills. <br />8. The drill pads and access roads reclamation procedure outlined above will <br />apply only to those areas newly disturbed for this proposed project. Existing <br />roads will be left in a condition equal to or better than that observed on <br />Mountain Coal Company's entry into the area or to the satisfaction of the <br />USFS representative. <br />9. Any coal recovered incidental to this project will be in the form of cuttings or <br />core and would either be taken back to the mine site or disposed of in the mud <br />pits. <br />DRILL HOLE PLUGGING METHODS: <br />The hole plugging methods described in 43 CFR II 3484.1(a) or Colorado <br />Division of Minerals and Geology (CDMG) Rules and Regulations at 4.07.3, will be used <br />for all holes. It is anticipated that each open hole will be plugged with cement from <br />bottom to 50 feet above the uppermost thick coal seam and from 50 feet below to 50 feet <br />above any aquifers encountered in the hole. The remainder of the hole will be filled with <br />an approved completion mud, gel, cuttings, or cement to within 5 feet of the surface. A <br />5- foot cement surface plug will be set, and an appropriately labeled monument marker <br />will be cemented into the surface plug. Surface casing will be cut off at or below the <br />level of the soil surface. <br />However, all of the proposed MDW's will be steel-cased and cemented in-place <br />effectively sealing the space between the outside annulus of the well and the rock strata. <br />Where the entire depth of the well is steel-cased alterriative plugging techniques may be <br />employed, after review with the regulatory agencies. MCC proposes a hole plugging <br />method that has met prior approval of USFS and CDMG. The holes utilized on the 2000 <br />Thermal Event drill holes were plugged with a bridge packer set 50' below ground level <br />in the steel casing with cement grout placed in the hole to surface. <br />r <br />16 <br />
