Reclamation Plan Exhibit E <br />1. General Reclamation Plan <br />The total disturbed area to be reclaimed under this permit is 92.7 acres. The post-mining land use for <br />the entire permit area will be lake surface and wetland in the lake areas and dry rangeland in the areas <br />above the wetlands. As seen in Map F, the final lake will have a varying shoreline to allow for a more <br />natural appearance. The mining plan contemplates the excavation of 5.60 acres of wetlands on the site. <br />The reclamation plan designates 38.71 acres for shelf and fringe wetlands this is more wetland <br />reclamation than any other pit in the State of Colorado. <br />The final appearance of the varied shoreline and wetland shelves constructed may differ from that seen <br />on Map F. The groundwater level on site is believed to be as high as 5719', due to the presence of <br />wetlands. The low point along the pit perimeter after mining is 5712', lower than the groundwater in <br />the western part of the pit, and thus the lake surface will most likely be at that elevation. <br />As described in the mining plan, reclamation of the sideslopes will occur concurrently with mining. All <br />mine slopes outside of the wetland footprints of 2H:1 V will be backfilled to 3H:1 V or less to 5' below <br />the lake surface elevation. Along the north and west mining perimeter a 6H:1 V slope will be in place <br />down to 10 feet below the water surface to protect against erosion during high river flows; most these <br />areas will not be backfilled. 10 feet below the water line and deeper will remain at 2H:1 V slopes in <br />these areas. A small peninsula will be constructed on the north side to add to the natural appearance of <br />the shoreline. This areas is at least 30 feet away from the nearest wetland footprint. The 3H:1 V slopes <br />along the south side of Phases 9-11 will not be backfilled either. In this area, the 3H:1V slope will <br />remain down to 10 feet below the water surface and then 2H:1 V slopes to the lake bottom. Overburden <br />from the current mining areas will be used to backfill designated areas as mining progresses, and build <br />the wetland shelf as shown on Map F. By doing this, the distance that overburden will have to be <br />transported, as well as the amount of material which will have to be rehandled will be minimized. <br />Additionally, the acreage which is unreclaimed will be minimized, which will make the worst case <br />reclamation smaller and thus, the bond will be smaller. No material will be stockpiled in any wetland <br />footprint during reclamation. <br />White River City Pit, August 08 E-1
