7. All aggregate material excavated from the mine phases will be dewatered and dry mined. <br /> 8. Equipment-The aggregate material will be mined using, but not limited to the following <br /> equipment. <br /> a. Earth moving equipment—Dozers, loaders, excavators, articulated haul trucks, water <br /> truck and possibly scrapers will be used for the mining and earth moving operations. <br /> b. Processing Equipment—Feeders, screens,jaw, cone, and impact crushers; screening <br /> plant, conveyors, stackers, and other miscellaneous processing equipment. All aggregate <br /> crushing/screening equipment is mobile for relocation in the mine. <br /> c. Dewatering the mine will be carried out with pumps, pump basins, pipelines, lay flat <br /> hose, steel traffic casings and ditches as necessary to support the various mining <br /> operations and to achieve dry mining conditions. <br /> d. Miscellaneous Equipment—Pumps for dust control systems, pipe,tanks, pickups, <br /> mechanics trucks, lube trucks,trash receptacles, metal recycle bins and portable toilets. <br /> e. No fuel will be stored on site. <br /> 9. The final site grading will return the property to topographic conditions consistent with pre- <br /> development conditions, as shown on the final reclamation map. <br /> 10. 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. <br /> C—Water diversions and impoundments— <br /> 1. Dewatering trenches will be constructed along the perimeter of each mining block.The <br /> dewatering trench around the perimeter of the mine block will be placed at the toe of the <br /> mining slope. As the block is mined deeper the dewatering trench will be lowered and moved <br /> laterally along the ±3H:1V mining slope toward the center of that block.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 mining block will require about three lifts to fully excavate the aggregate material <br /> from each block.The dewatering ditches will flow to a pump basin, water will be pumped into a <br /> discharge ditch which flows from the wash plant and eventually discharges into the South Platte <br /> River at the Northeast corner of the 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 /> H\Pits HBP Plants\EVANS\Evans Mining Resource\DRMS Adequacy Revisions\Exh D Mine Plan Rev 101822 docx <br />
