0 <br /> 2 .05.4 RECLAMATION PLAN <br /> ( 1) Reclamation will commence with the clearing and the <br /> initial salvage of topsoil material from mine facility areas and <br /> will conclude with the revegetation of the final reclaimed dis- <br /> turbance areas. <br /> (2 ) (a) A detailed time schedule of amount of acreage to be <br /> reclaimed in one year increments is presented in Section 2.05.3 (2 ) . <br /> This schedule is based on a production rate of 350,000 tons per <br /> year. The schedule will obviously change if the production rate <br /> varies significantly. <br /> (b) The amount of performance bond is developed assuming <br /> that the bond would be forfeited at the time reclamation <br /> liabilities are highest within the five-year permit term. This <br /> worst case condition would occur at the stage in the mining <br /> sequence when and if Mining Area No. 1 and Mining Area No. 2 were <br /> being mined concurrently. The worst case would occur when there <br /> is the maximum amount of material in two spoil stockpiles and in <br /> the three topsoil stockpiles. The worst case is assumed to occur <br /> when there is the maximum amount of excess spoil in each mining <br /> area. According to the spoil balance tables presented in Exhibit <br /> 12, the point when there is the maximum amount of excess spoil <br /> occurs when mining is commencing in Pit 26 and Pit 30 in mining <br /> Area 1 and Area 2 respectively. <br /> • In Area 1 the worst case occurs after pit 26 is <br /> excavated. At this point the pit void is 113,500 CY and the excess <br /> spoil volume in the spoil ridges is 55,857 CY. Pit 26 is 2100 feet <br /> long and 90 feet wide. The 55,857 CY spoil ridge and the 81,000 CY <br /> stockpile provide an excess spoil quantity of 23,357 CY which will <br /> be spread around the area to help blend the pit into the <br /> undisturbed area. No highwall reduction would be required. <br /> In Area 2 the worst case occurs after pit 30 is <br /> excavated. At this point the pit void is 166,250 CY and the excess <br /> spoil in the spoil ridges is 57,830 CY. Pit 30 is 1800 feet long <br /> and 90 feet wide. After the 57,830 CY spoil ridge and the 19, 608 <br /> CY stockpile is graded into pit 30, there is still a shortfall of <br /> 88,812. This material would be generated from pit highwall <br /> reduction. <br /> The work required at this worst case point in both <br /> pits is to regrade the spoil ridges and backfill the open pits with <br /> the excess spoil. The spoil pile from each area would also be <br /> hauled to the open pit in each respective area. Then in order to <br /> meet approximate original contour the area surrounding the open pit <br /> would have to be graded to the pit. The material balance for this <br /> operation is as follows: <br /> 2 .05-17 May 1992 <br />
