• 2.05.3 <br />was added to topsoil stockpile E during the expansion of the coverfill pile during <br />2003. <br /> Pile D Pile E Grand Total <br />Quantity (CY) 4,500 1,600 161,000 <br />A total of 56,800 cubic yards of topsoil was stripped and stockpiled during the <br />construction of the unit train loadout. This quantity results in an average 1.1 foot <br />replacement depth within the disturbed area at the loadout including the <br />disturbance associated with Ponds J & K. The topsoil is stored in topsoil <br />stockpile F. Construction of Gob Pile No. 3 will result in approximately 70,000 <br />CY of topsoil that will be stored in Topsoil Stockpile F-1. <br />The design of the gob pile in 2003 was a 10-year design. At the time of this <br />writing, in May 2006, the gob pile is nearly full and ready to be reclaimed. To <br />reclaim the entire gob pile, approximately 1.0 feet of topsoil will be placed on <br />the completed construction face. In total, the operator salvaged approximately <br />50,000 CY of topsoil. Material from the stockpile, new borrow area and the <br />topsoil stockpile will be utilized for reclamation. See Appendix A in Volume IX <br />for material balance details. Topsoil will be stored in topsoil stockpile E as <br />shown on Figure I located in Volume IX. <br />Construction of the drill pad located immediately above the utility bench during <br />late 2004 will the require that approximately 1,000 cubic yards of topsoil be <br />salvaged. The topsoil will be stored in topsoil stockpile "G" which is located on <br />top of the B-Seam portal excess material stockpile. <br />At the Hubbard Creek Shaft construction site, topsoil will be salvaged. To <br />preserve space the topsoil will be stockpiled on the cut slope. If the 1.8 acre <br />disturbance has an average of 6" of topsoil, 1,450 cubic yards of topsoil will be <br />salvaged. The cut slope will have 2.25 feet of topsoil placed on it for storage if <br />the full 1,450 cubic yards are salvaged. The proposed construction site is strewn <br />with large sandstone boulders so topsoil salvage will be difficult. <br />Topsoil stockpiles were and will be constructed to reduce erosion of the <br />stockpiles by either wind or water. The topsoil stockpiles are located on stable <br />surfaces where they will not be disturbed by the mining operation. Topsoil <br />stockpiles that are to remain in place for more than ninety days will be seeded as <br />soon as practical and berms will be constructed around the base of stockpiles <br />• where necessary to prevent loss of topsoil material from the stockpiles. <br />TR-47 <br />2.05 - 38 - 03/07 <br />HppRovsD <br />7 jt7~67 <br />
