2.05.4 page 4 MR29, TR09 August 2005 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 already be in its final shape because "final shape" will be maintained at all times as the pile grows. 3.5 feet of cover will be placed on all previously uncovered surfaces prior to the addition of plant growth medium. These surfaces will consist only of the top area ofthe 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 azea 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 area 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 area around 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 area shown on Map C-4. The Topsoil Borrow Area consists of an azea of approximately 1.5-2.0 acres with an estimated average depth of 7 feet, or approximately 16,940 cubic yards of material. This area has been sampled and analyzed by the soils lab at Colorado State University. For results of these analyses, see Appendix 9(4)(a). The area under stockpiled soil will not require replacement of plant growth medium; however, all areas disturbed by removal of plant growth medium will be reclaimed in the same manner as described for mine disturbed area in Section 2.05.4. Suitable plant growth medium should also be obtainable from the sediment ponds overburden and embankment material. These soils have also been sampled and analyzed by the soils lab at Colorado State University (See Appendix 9(4)(a)). Stockpiled soils (Subsoil Storage Area) are free from contamination with stockpiled coal and are located so as to eliminate erosion of the stored soils (See Map C-4). Reclamation of the permit azea would commence at the end of the life of the mine. RECLAMATION-PLANT GROWTH MEDIUM All stockpiled plant growth medium plus the suitable overburden sediment pond material to be used in reclamation will be tested for the following parameters: 1. pH 2. Conductivity 3. Texture (particle size distribution) 4. Sodium absorption ratio 5. Saturation percentage 6. If pH is over 8, test will be made for selenium and boron.
