2.05.4 page 4 August 2005 WASTE PILE RECLAMATION Refer to section 2.05.3 (Waste Pile Design) for a detailed description of the coal mine waste (refuse) storage area. Technical Revision TR-08 addresses reconstruction of the waste pile. Designs for this reconstruction have been provided by Don May, P.E. and are located in Appendix 7, Upon completion of the reconfiguration of the waste pile as designed in TR-08, fill material was used to cover the face of the pile to the required depth. This fill material was salvaged during reconstruction of the existing waste pile and is composed of about 50% rock and 50% earth. After compaction of this fill material, plant growth medium was spread as required by this section and the azea was re-vegetated. This brought the existing face of the pile to final reclamation status. Future waste pile reclamation will entail stockpiling plant growth medium and fill material which will be salvaged while extending the waste pile as it grows. As the waste pile slowly increases in size, all available fill material and plant growth medium will be removed and stockpiled at the east boundary of each 5 year design phase. As the face of the pile rises, material from this stockpile will be drawn upon and used to reclaim the face of the waste pile as outlined above. Should additional fill material be required at final reclamation, suitable material from the designated borrow area will be used. At the time of final reclamation, the refuse pile will aheady be in its final shape because "final shape" will be maintained at all times as the pile grows. 3.5 feet of wver will be placed on all previously unwvered surfaces prior to the addition of plant growth medium. These surfaces will consist only of the top area of the waste pile (1.85 acres at the end of this 5 year permit term). Plant growth medium will be spread evenly to a finished depth of 6 inches and the area planted per methods outlined in this section. The road which serves as access to the top of the waste pile will be left in place as per request from Lawrence Huntington (See Appendix 9(1). This road is an easement to Mr. Huntington's property. PLANT GROWTH MEDIUM DISPERSEMENT AND GRADING As no topsoil was salvaged from the disturbed areas during construction of the original mine facilities, there is no topsoil available for replacement. Plant growth medium material stockpiled during construction of the waste pile will be required for use at the waste pile during reclamation. With removal of coal and coal materials from the surface of the facilities area, suitable plant growth medium should become available. Additional suitable plant growth medium may be available from re-grading throughout the facilities area. Where suitable material is exposed, it will be isolated or stockpiled for replacement. Suitable material under the coal of the facilities azea will be ripped or disked after final grades are achieved to loosen the material. Efforts will be made to ensure that all available suitable plant growth medium is salvaged and/or replaced for revegetation. Additional plant growth medium for reclamation may be available from an azea azound and above the shop building and coal storage area that was stockpiled in the upper reaches of the east drainage prior to 1972. It has overgrown with natural vegetation, and is therefore stabilized and protected adequately from wind and water erosion. The upper reaches of the east drainage area in which stockpiled plant growth medium lies is included in the disturbed azea shown on Map C-4. The Topsoil Borrow Area consists of an area of approximately 1.5-2.0 acres with an estimated average depth of 7 feet, or approximately 16,940 cubic yazds of material. This azea has been sampled and analyzed by the soils lab at Colorado State University. For results of these analyses, see Appendix
