EXHIBIT E <br /> Reclamation Plan <br /> A groundwater lake with wetland mitigation areas will be the final reclaimed use for the River <br /> Valley Resource site. In this area of Routt County, agriculture is a predominant land use along <br /> the Yampa River, and therefore, the proposed post mining use is compatible with surrounding <br /> land uses. The groundwater lake will encompass the majority of the site. The remaining area <br /> within the proposed permit boundary will consist of lake shoreline, backfilled/wetland mitigation <br /> areas, and reclaimed or otherwise undisturbed land. The approximate acreage of each of these <br /> areas is: <br /> Final Land Use Area acres <br /> Groundwater Lake 64 <br /> Shoreline 5 <br /> Backfilled/Wetland Replacement Areas 10 <br /> Reclaimed or Undisturbed Land 26 <br /> TOTAL 105 <br /> Replacement Wetlands <br /> As illustrated in Exhibit F, Reclamation Plan Map, portions of Phases 1, 2, and 4 in the western <br /> portion of the site will be backfilled to create replacement wetlands. Similarly, portions of Phases <br /> 8 and 10 on the eastern side of the site will be backfilled to create wetland areas (Reclamation <br /> Plan Map, Exhibit F). It is anticipated that the western most portions of Phases 1, 2, and 4 will be <br /> used as sediment basins for process fines generated from the aggregate washing plant. The <br /> sediment basins are sized to contain the anticipated volume of fines generated from the aggregate <br /> washing activity. The basins will be filled with fines to within 1 to 3 feet of the existing <br /> groundwater elevation. As the basin forms deltas and reaches capacity, emergent wetland <br /> vegetation will begin to colonize the area. 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:I V grade. <br /> Reclamation Measures/Materials Handline <br /> The mining will create the rough topography for the lakeshore and the replacement wetlands (see <br /> Reclamation Plan Map, Exhibit F). The backfrlling will be done to provide stabilized shorelines <br /> around the reservoirs and to minimize erosion. The backfill material will consist of native <br /> bedrock claystone, overburden, and topsoil. Throughout the life of the mine, inert material from <br /> on-site and off-site sources will be used to backfill shorelines. There will not be any known toxic <br /> or hazardous materials in the backfill material. Additionally, acid forming or toxic materials will <br /> not be encountered during mining. <br /> The mining will not leave highwalls on the property. There will be no auger holes, adits, or <br /> shads left on the property. <br /> i <br /> River Valley Resource <br /> DMG 112 Permir j <br /> Page 8 1 <br />
