(b) Earthmoving; <br /> Topsoil and overburden will be stripped with scrapers or bulldozers and stockpiled <br /> along the permit boundary as depicted on Exhibit C of the mining plan map (Sheet 3). <br /> (c) All water diversions and impoundments;and <br /> Excess water in the pit is pumped into a settling pond and discharged in accordance <br /> with a CDPS permit. Wash water for the processing area is recycled through a series <br /> of small ponds within the processing area. The water required to operate the facility is <br /> provided by the existing water rights associated with the property. No ditches will be <br /> disturbed without prior authorization of the appropriate ditch company. <br /> (d) The size of area(s) to be worked at any one time. <br /> 60 acres. <br /> (e) An approximate timetable to describe the mining operation. The timetable is for <br /> the purpose of establishing the relationship between mining and reclamation <br /> during the different phases of a mining operation. <br /> The Operator anticipates extracting approximately 500,000 tons to 1,000,000 tons of <br /> aggregate per year, however, production rate may vary based on market demands. <br /> Timetable for Mining and Reclamation <br /> There is approximately 3 to 5 years of mining reserves remaining in the main mine. <br /> Phasel will be mined first, then Phase 2 and Phase 3. <br /> Reclamation will begin immediately after mining is complete. When possible, <br /> concurrent reclamation practices will be used to minimize site disturbance and to limit <br /> material handling to the greatest extent possible. Please refer to the Mining Plan Map <br /> in Exhibit C (Sheet 3)for phase areas to be mined, locations and areas. <br /> (t) Use Mining Plan Map in conjunction with narrative to present: <br /> (i.) Nature, depth and thickness of the deposit and thickness and type of <br /> overburden to be removed <br /> The bedrock depths in the proposed mine areas ranged from approximately 35 <br /> feet to 50 feet below the ground surface. <br /> (ii.) Nature of the stratum immediately beneath the material to be mined in <br /> sedimentary deposits <br /> The site is located approximately 25 miles east of the foothills of the Colorado <br /> Front Range on the western flank of the Denver Structural Basin. The basin is a <br /> BURNCO COLORADO LLC-Tricycle Amendment-Nissen Mine—MLRB 112 Permit Application <br /> Exhibit D-2 <br />
