As the area is <br />mined, overburden will be placed along the edges to create the shoreline of a future <br />pond. Topsoil will be placed on finished grades and the area will be seeded. Afrer <br />the mining of a phase is substantialy completed, a dewatering trench will be <br />constructed around the next phase to be mined and the process will begin again. <br />b. Earthmoving: sand and gravel will be excavated by loader and loaded onto <br />conveyors or haul trucks which will convey the material to the processing area. <br />c. All water diversions and impoundments: the perimeter of the mining phase will be <br />dewatered by digging a trench approximately 34 feet deep to bedrock. The water will <br />be pumped and discharged into a pond on the property, then into a ditch which <br />discharges to the Platte River. Wash water for the processing equipment will be <br />recycled through a series of small ponds within the processing site (see Mining Plan <br />Map). Upon completion of mining Phase I, the wash ponds will be relocated to the <br />Phase I mining area for the remainder of the operation. All water required to operate <br />the facility will be provided by the existing water rights associated with the property <br />or water rights purchased for the project. <br />d. Size of the area to be worked at any one time within the mining area: excluding ,;.,~' <br />the processing area and stockpiles, a maximum of 25 acres will be disturbed at any .; ' <br />one time. Concurrent reclamation of the site will include grading, replacement of <br />topsoil and seeding of the pond embankments. Undisturbed areas will be managed asp '~, <br />irtigated pasture or other appropriate cover crop until mining commences on each ' <br />phase. <br />e. Timing: The applicant anticipates that mining will begin in the winter of 2001. It <br />will take approximately 8 to 10 years to mine and reclaim this property. Annual <br />production is estimated to be between 320,000 and 500,000 tons. This may vary <br />depending upon the demand for construction material which may impact the total life <br />of the mining operation. The property will be mined in 7 phases, each phase will take <br />between 10 to 16 months to complete (see Mining Plan Map). Reclamation will <br />proceed in conjunction with the mining of each phase and will consist of regrading, <br />backfilling, replacement of topsoil and seeding of pond banks. <br />Nature, depth and thickness of the deposit to be mined and the thickness and <br />type of overburden to be removed: Please refer to Exhibit I -Soils Information for <br />a copy of the test hole logs. The nature, depth and thickness of the deposit to be <br />mined and the thickness and type of overburden to be removed is shown on the test <br />hole logs. <br />NCCI dlining Proposal jor the NCC/ Pit # 1- MLRB 1 /1Permit <br />~" <br />.J <br />i <br />:.'' <br />4 <br />L~.a-~~' is <br />i~ <br />
