Buildings and Structures <br /> There are no existing buildings or structures in the proposed permit area and no structures will be <br /> left following reclamation. <br /> Signs and Markers <br /> Permit notification signs will be placed and maintained at the entrance to the operation. The <br /> permit boundary will be identified where it is not already identified by fences or suitable <br /> markers. All signs and markers will be removed upon permit release. <br /> Reclamation Costs <br /> In order to calculate maximum potential reclamation liability to the State, we have selected a <br /> point in time where reclamation costs could be at a maximum. It is assumed that the time of <br /> maximum mining disturbance could be at the completion of all mining activities. Although <br /> concurrent reclamation is expected to be performed during all phases of mining, during the <br /> worst-case scenario, no reclamation will have been performed during mining. Backfilling of the <br /> side slopes to 3H:1 V has not begun. Stockpiles with available topsoil/overburden for backfilling <br /> will be near the pit and areas for reclamation, so haul distances will generally be less than <br /> 500 feet. Each aspect is listed in the following table with associated disturbed area. Please refer <br /> to Exhibit C, Mining Plan, for a listing of disturbed areas that total 9.9 acres. This estimate will <br /> follow the same order as the listing in Exhibit C. Unit costs for reclamation activities were <br /> provided from bidding documents associated with similar projects. Since all structures used in <br /> the mining operation are portable, it is assumed that removal of the structures do not have <br /> associated costs. <br /> The completed mining area will include near vertical pit side slopes and un-reclaimed pit floor. <br /> The near vertical pit slopes will total 3,960 linear feet with a height of 10 feet. The exposed pit <br /> floor requiring reclamation will be approximately five (5) acres. As all mining is completed, <br /> reclamation will begin, so it is assumed that during this worst-case scenario no concurrent <br /> reclamation has been performed. <br /> Miscellaneous disturbed areas at the point of maximum disturbance will include internal haul <br /> roads and other miscellaneous mining related disturbances. These areas will be tilled in <br /> preparation for topsoil/overburden growth medium placement, final grading, and seeding for <br /> revegetation. It is estimated that the combined area of these disturbances will be approximately <br /> 3.4 acres. <br /> Since quality topsoil is thin on the Harmony Windsor Site, vegetation growth medium will <br /> include the best quality topsoil/overburden material available. If available, a minimum of <br /> 4 inches of growth medium will be placed on all disturbed areas following backfilling, <br /> scarifying, and/or rough grading. Final grading of the topsoil/overburden growth medium will <br /> prepare the surface for seeding. After initial seeding and the first season's growth, it is estimated <br /> that approximately 20 percent of the seeded area will need to be re-seeded. <br /> A breakdown of the estimated reclamation costs during the scenario presented above is provided <br /> in the following table. <br /> Harmony Windsor Site <br /> DRMS Limited Impact 110 Permit Application Page 15 <br />
