c. Dewatering the mine will be carried out with pumps, pump basins, pipelines,and <br /> ditches as necessary to support the various mining operations and to achieve dry mining <br /> conditions. <br /> d. Miscellaneous Equipment—Pumps for dust control systems, pipe,tanks, pickups, <br /> mechanics trucks, lube trucks,trash receptacles, metal recycle bins, portable toilets, <br /> truck scales, scale house/office and asphalt hot plant. <br /> e. No fuel will be stored on site. <br /> 6. The final site grading of each mine Phase will return the property to topographic conditions <br /> consistent with pre-development conditions,as shown on the final reclamation map. <br /> 7. All local,state,and federal rules, regulations and laws will be followed for the storage and <br /> handling of any fuel, asphalt and additives needed to produce hot asphalt materials, mine <br /> aggregates and recycle aggregate materials. <br /> C—Water diversions and impoundments— <br /> 1. Dewatering trenches will be constructed along the perimeter of each mining area.The <br /> dewatering trench around the perimeter of the mine will be placed at the toe of the mining <br /> slope. As a Phase is mined deeper the dewatering trench will be lowered and moved laterally <br /> along the ±3H:1V mining slope toward the center of that mine area.The depth of the <br /> ditches will vary as the mining progresses deeper into the alluvium to keep the ground water <br /> level below the active mining bottom surface and minimize the exposed groundwater surface <br /> area. Each mine Phase will require about three lifts to fully excavate the aggregate material.The <br /> dewatering ditches will flow to a pump basin,water will be pumped into a discharge ditch which <br /> traverses the north end of the mining Phases and eventually discharges into the South Platte <br /> River at the Northeast corner of the mine property. <br /> 2. Flood Plain/Flood Way—The entire site is in either the South Platte River flood plain or flood <br /> way. No material fill will take place in the flood way above the existing ground elevation. No <br /> filling with construction material will not take place within one hundred (100)feet of the South <br /> Platte River. <br /> 3. Surface Water/Drainage-All mine site operations take place below pre-development grades. <br /> All surface drainage water is to be collected at lower elevations from the mining operations.The <br /> collected waters uses include dust suppression,allowed to evaporate,or discharged per the <br /> substitute water supply plan. <br /> 4. Wetlands-There are no wetlands found within mine boundaries. <br /> 5. Asphalt Specialties will have approved flood permits,gravel pit well permit and a substitute <br /> water supply plan prior to exposing groundwater or working in the floodway. Revision of the <br /> substitute water supply plan takes place annually and accounts for water consumed by <br /> exposing groundwater to evaporation, dust control and water contained in the aggregate <br /> materials. Precipitation runs off are contained in the mine areas for use as dust suppression or <br /> allowed to evaporate. <br />
