• If sufficient overburden remains at the end of mining, a small island for wildlife habitat will be <br />created as shown on Map F, Reclamation Plan Map. The size of the island will depend on the <br />amount of over burden that remains after mining is complete. However, for the purpose of <br />calculating the reclamation bond, the island is assumed to have a maximum size of 17.27 acres, <br />which would be the worst case scenario in a bond forfeiture scenario. It is anticipated that this <br />island would be created by the time Phase 10 is completed. If created, the island will have a top <br />elevation of 4952, which is estimated to be four feet above the anticipated water surface <br />elevation of the lake and a size varying between 0.0 acres and 17.27 acres. The island will have <br />a slope of 4H:1 V from the top of the island to ten feet below the water surface. From ten feet <br />below the water surface to the bottom of the island, the slope will be 2H:1 V. The wetland fringe <br />azound the island will be fifteen feet wide. A minimum of twelve inches of topsoil will then be <br />placed on the entire island except the azea that is greater than ten feet below expected water <br />level. The exposed section of the island will be vegetated with the dryland seed mix while the <br />wetland fringe will be vegetated with the wetland seed mix, as presented in the Revegetation <br />• Plan section of this exhibit. <br />The total amount of material required to achieve the planned reclamation with the maximum size <br />island (17.27 acres) is estimated to be 3,150,445 cubic yazds. Of this amount, 168,609 cubic <br />yards will be topsoil while the remainder, 2,981,836 cubic yards, will be overburden. <br />The worst case reclamation scenario occurs when mining is completed in Phase 11. At this <br />point, all previous mining areas will have been backfilled and graded. Reclamation at this point <br />will consist of backfilling the 2H:1 V slope along the west and south faces of Phase 11 to the <br />3H:1 V slope as shown on Map F; replacing topsoil on and revegetating the reclaimed slopes; <br />removal of several structures such as the Redi-mix plant and fuel bunker and reclaiming the <br />Redi-mix/asphalt plant azea; and revegetating the wetland fringe around the lake perimeter and <br />island perimeter. The reclamation timetable is shown below in Section 2 and in Table E-1. The <br />worst reclamation costs associated with the worst case scenario is calculated in Exhibit L: <br />Reclamation Costs. <br />1 <br />Anderson Pit, Apri107 E-2 <br />
