2.05.4 page 3 <br />MR29, TR09 August 2005 <br />require approximately 400 cubic yards of material. After back-filling to a depth of 25 feet from the portal, <br />the mouth of the portals will be caved to completely seal them. The highwall area will then be back-filled, <br />graded to a 2:1 slope. <br />Coal exploration drill hole N-16 and a vent hole in the mine plan area have already been capped with <br />concrete plugs and meet reclamation requirements. A dry well hole next to the water tank has been filled. <br />The active well on the permit azea (See Map C-4) will remain open and in active use for future use by <br />owners of the property. This well is enclosed in a housing and collared. See Map C-3 for location(s) of any <br />vent/air shafts or holes. <br />GRADING AND BACKFILLING <br />The mine has been in some Form of continual operation sine the mid 1940's. Therefore, with the <br />exception of the newly constructed coal refuse pile, the entire site falls under the Previously Disturbed <br />category. No topsoil was salvaged prior to SMCRA ,therefore, not all areas to be reclaimed will receive <br />topsoil. Attempts for 6" of growth medium will be replaced on the Upper Facilities Area, reclaimed <br />highwall areas, and the refuse pile. The pond area (Area 1) and the Lower Facilities area (Area 2 on Map C- <br />6) aze not scheduled to receive any plant growth medium except that which may lie in and around the areas. <br />The tipple area highwall, and shop area highwall shown on Map C-7 will be back-filled in 2 foot lifts <br />to a slope of 2:1 utilizing mine waste and fill rock. The benches, however, will be graded and contoured to <br />a 2.5:1 slope gradually sloping to 3:1. <br />#6). <br />Analysis of stored waste, as tested by C. T. & E. is included in Appendix 9(4) (Samples #4, #5 & <br />Rock lined stilling basins will be constructed at three locations depicted on the final contour map (C-7). <br />The basins will be installed along with the final drainage channels after a successful Phase II Bond release, <br />Volume for reclamation costs estimates are based on surface area delineations as well as grid surfaces <br />calculated from existing and final contour maps using computer software programs. (See reclamation cost <br />estimates for more details) <br />WASTE PILE RECLAMATION <br />Refer to section 2.05.3 (Waste Pile Design) for a detailed description of the coal mine waste (refuse) <br />storage area. Technical Revision TR-08 addresses reconstruction of the waste pile. Designs for this <br />reconstruction have been provided by Don May, P.E. and are located in Appendix 7. <br />Upon completion of the reconfiguration of the waste pile as designed in TR-08, fill material was <br />used to cover the face of the pile to the required depth. This fill material was salvaged during reconstruction <br />of the existing waste pile and is composed of about 50% rock and 50% earth. After compaction of this fill <br />material, plant growth medium was spread as required by this section and the area was re-vegetated. This <br />brought the existing face of the pile to final reclamation status. <br />Future waste pile reclamation will entail stockpiling plant growth medium and fill material which <br />will be salvaged while extending the waste pile as it grows. As the waste pile slowly increases in size, all <br />
