All reservoir slopes left by the mining operation will be reclaimed to at least 3H:1 V final grade. <br />Reclamation of the side slopes will be concurrent with mining, with reclamation activities <br />following approximately 1,000 feet behind the mining operation. Since reclamation will be <br />concurrent with mining, most soil, overburden, and bedrock material excavated during mining <br />will be used almost immediately. Scrapers will be used to place bedrock claystone and <br />overburden material along the reservoir perimeters to achieve the final grade. Final reclamation <br />by capping with topsoil and re-vegetating above the expected reservoir water level will follow <br />backfilling operations closely to minimize the amount of disturbance at any one time. <br />During reclamation activities, inlet and outlet works for the reservoirs will be installed. The inlet <br />works will be constructed to provide water from the Brighton Ditch along the west side of the <br />site. In the northeastern portion of the site, outlet works will be constructed to deliver reservoir <br />water to the South Platte River. The general location of the inlet and outlet works is illustrated <br />on Exhibit F, Reclamation Plan. The design specifications and plans for the facilities will be <br />provided to the Division prior to construction. <br />Replacement Wetlands and Riparian Area <br />Mining areas 1, 2, and 3 will be backfilled and reclaimed as replacement wetland/riparian azeas. <br />Reclamation will begin in Phase I as Pond 2 and mining areas 2 and 3 aze mined. Stripped <br />overburden from mining activities will be used immediately to backfill the mined portion of <br />mining areas 2 and 3. As mining progresses into Phase II, additional excavated overburden and <br />bedrock claystone material from Pond 1 will be used to backfill mining azeas 2 and 3. Also <br />during Phase II, overburden material from mining azea 1 will be placed back in the pit for final <br />reclamation. Backfilling of mining area 1 will be completed during Phase III and excavation of <br />Pond 3. Finally, a minimum six inches of topsoil will be used to cap the mining areas and <br />provide a growing medium for wetland plants. Depending on groundwater elevations, the final <br />surface elevation of the backfilled areas may be below the existing and surrounding ground <br />elevation. Any slopes remaining will be reclaimed to a minimum 3H:1 V grade. <br />Reclamation Measures/Materials Handlinc <br />The mining will create the rough topography for the three reservoir shorelines and the <br />replacement wetlands (see Reclamation Plan Map, Exhibit F). The backfilling will be done to <br />provide stabilized shorelines around the reservoirs and to minimize erosion. The backfill <br />material will consist of native bedrock claystone, overburden, and topsoil. There will not be <br />known toxic or hazazdous materials in the backfill material. Additionally, it is not likely that <br />acid forming or toxic materials will be encountered during mining. <br />Each mining area will be reclaimed using soil, overburden, process fines and other inert <br />materials from on-site. However, if materials from off-site are used, the applicant will provide <br />the Division with the appropriate notices and affidavit in accordance with Rule 3.1.5(9). <br />The mining will not leave high walls on the property. There will be no auger holes, adits, or <br />shafts left on the property. <br />Wadenbe~g lakes <br />DMG 112 Permit <br />Page 10 <br />
