EXHIBIT E <br /> Reclamation Plan <br /> Water storage will be the primary final reclaimed use for the Derr Pit Project site. <br /> Portions of mining areas will be backfilled and reclaimed as "native" areas, which will be <br /> re-seeded with native vegetation and will also include areas where native trees could be <br /> re-planted. The majority of the mining areas will be reclaimed as a water storage <br /> reservoir. The remaining area within the proposed permit boundary will consist of <br /> reservoir shoreline, unimproved access roads around the reservoir, and reclaimed or <br /> otherwise undisturbed land. The approximate acreage of each of these areas is: <br /> Final Land Use Reclamation Alternate <br /> Plan Area Reclamation Plan <br /> (acres) Area (acres) <br /> Reservoir(s) Water Surface 64.30 68.41 <br /> Street/County Roads/Access Roads 4.65 4.65 <br /> Reclaimed Vegetated Land and Undisturbed 71.10 71.99 <br /> Land <br /> TOTAL 145.05 145.05 <br /> Water Storage Reservoir(s) <br /> In general, the mining limits will be mined to the siltstone/claystone bedrock. The <br /> relatively impermeable bedrock will make the bottom of the reservoir. The reservoir will <br /> also be separated from the surrounding alluvial aquifer by a slurry wall liner. The slurry <br /> wall liner will be keyed into the bedrock material and extend upward through the entire <br /> height of the alluvium. Design specifications and quality control procedures used during <br /> construction of the slurry wall liner will ensure that the reservoir meets State Engineer's <br /> Office (SEO) performance standards for permeability. The slurry wall liner will be <br /> constructed between year two and year three of the mining. <br /> All reservoir slopes left by the mining operation will be reclaimed to at least 3H:1V final <br /> grade. Reclamation of the exterior cell walls will be concurrent with mining. Since <br /> reclamation will be concurrent with mining, most soil, overburden, and bedrock material <br /> excavated during mining will be used almost immediately. Scrapers and dozers will be <br /> used to place overburden material along the reservoir perimeters to achieve the final <br /> grade. Upon placing the backfill material, 95 percent compaction will be achieved to <br /> insure adequate integrity of the slope. Final reclamation by capping with topsoil and re- <br /> vegetating above the expected reservoir water level will follow backfilling operations <br /> closely to minimize the amount of disturbance at any one time. <br /> Reclamation Measures/Materials Handling <br /> Backfilling will be done to provide stabilized shorelines around the reservoir and to <br /> minimize erosion. The backfill material will consist of native bedrock claystone, gravel, <br /> overburden, and topsoil.
