RECLAMATION PLAN E~~IT E <br />1. General Reclamation Plan <br />The total disturbed area to be reclaimed under this permit is 182.6 acres. The post-mining land use <br />for the permit area will be irrigated fields on all flat areas and dry rangeland on the slopes. <br />Approximately 150.09 acres will be reclaimed to imgated field and 32.51 acres will be reclaimed to <br />dry rangeland. Overburden and topsoil will be replaced on the pit floor in order to restore the <br />irrigated fields. Map F shows the post-mining topography. <br />As described in the mining plan, reclamation will occur concurrently with mining. Topsoil from the <br />current mining phase will be used to reclaim the Phase which has previously been mined. By doing <br />this the distance that the topsoil and overburden will have to be transported as well as the amount of <br />material which will have to be rehandled will be minimized. Additionally, the acreage which is <br />unreclaimed will be minimized, which will make the worst case reclamation smaller and thus, the <br />bond will be smaller. The worst case reclamation scenario occurs at the conclusion of the mining of <br />Stages A and B. At this point the amount of amount of material which will need to be moved to <br />reclaim the Phases will be the greatest at approximately 136,000 cubic yards. The topsoil berms <br />which are around the entire pit perimeter and temporary overburden stockpiles would have to be <br />rehandled and regraded into the mining slopes in order to bring the slopes to a 3H:1 V slope. All of <br />the equipment on site will be portable, so there will be no cost associated with removing these items. <br />The reclamation timetable is shown below in Section 2 in Table E-2 and the worst case scenario is <br />calculated in Exhibit L: Reclamation Costs. <br />Since the pit will be mined at a 2H:1 V slope, all slopes will have to be backfilled to a 3H:1 V slope in <br />order to ensure that the slopes will be stable for the post mining use. Due to the thickness of the <br />topsoil and overburden, which is approximately 3.0 feet (2.5 feet of overburden and 0.5 feet of <br />topsoil), the amount of material which is needed to reclaim the slopes is less than the amount of <br />overburden and topsoil which was present prior to mining. The extra material will be used as fill in <br />the bottom of the pit and will fill approximately 1.8 feet above the mining level. Additionally, six <br />Haldorson Sand and Gravel Mine 19 <br />
