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 may be at the completion of Phase I. Although concurrent <br /> reclamation is expected to be performed during Phase I, during the worst-case scenario, no <br /> reclamation will have been performed in the Phase I pit. Backfilling of the side slopes to 3H:1 V <br /> has not begun. Stockpiles with available topsoil/overburden for backfilling will be near the pit <br /> and areas for reclamation, so haul distances will generally be less than 500 feet. Each aspect is <br /> listed in the following table with associated disturbed area. Please refer to Exhibit C, Mining <br /> Plan, for a listing of disturbed areas that total 3.5 acres. This estimate will follow the same order <br /> as the listing in Exhibit C. Connell Resources Inc. is an earth moving and construction <br /> contractor and unit costs for reclamation activities were provided from bidding documents <br /> associated with similar projects. Since all structures used in the mining operation are portable, it <br /> is assumed that removal of the structures do not have associated costs. <br /> The active mining area will include near vertical pit side slopes and un-reclaimed pit floor. The <br /> near vertical pit slopes in Phase I will total 1,500 linear feet with a height of 10 feet. The <br /> exposed pit floor requiring reclamation will be less than three (3) acres. As Phase II is initiated, <br /> Phase I reclamation will begin, so it is assumed that during this worst-case scenario there are no <br /> disturbances associated with Phase U. <br /> Miscellaneous disturbed areas at the point of maximum disturbance will include internal haul <br /> roads and other related disturbances. These areas will be tilled in preparation for <br /> topsoil/overburden growth medium placement, final grading, and seeding for revegetation. It is <br /> estimated that the combined area of these disturbances will be approximately one-half <br /> (0.5) acres. <br /> Since quality topsoil is thin on the Harmony Gardens 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 Gardens Site <br /> DBMS Limited Impact 110 Permit Application Page 15 <br />
