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 Area acres <br />Reservoir 30.38 <br />Street/County Roads/Access Roads 1.3(+/-) <br />or Undisturbed Land 7.51 +/- <br />TOTAL 39.19 <br />Water Storage Reservoir <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 31-11V 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 />During reclamation activities, inlet and outlet facilities for the reservoir will be designed <br />and installed once the end use of the proposed reservoir has been identified. <br />Derr Pit Project <br />J&T Consulting, Inc.
