EXHIBIT E <br />Reclamation Plan <br />Water storage will be the primary final reclaimed use for the SerFer Project site. Portions of the <br />mining site will be backfilled and reclaimed as "native" areas, which will be re-seeded with <br />native vegetation. The northern portion of the mining site will be reclaimed as a water storage <br />reservoir with a storage capacity to top of crest of approximately 220 ac-ft. The remaining area <br />within the proposed permit boundary will consist of reservoir shoreline, unimproved access <br />roads around the reservoir, and reclaimed or otherwise undisturbed land. The approximate <br />acreage of each of these areas is: <br />Final Land Use Area (acres) <br />Reservoir 20 <br />Access Roads 1.5 (+/-) <br />Reclaimed or Undisturbed Land 23.5 (+/-) <br />TOTAL 45 (+/-) <br />Water Storage Reservoir <br />In general, the mining cells will be mined to the claystone bedrock. The relatively impermeable <br />bedrock will make the bottom of the reservoir. The reservoir will also be separated from the <br />surrounding alluvial aquifer by a clay liner. The clay liner will be keyed into the bedrock <br />material and extend upward through the entire height of the alluvium. Design specifications and <br />quality control procedures used during construction of the clay liner will ensure that the reservoir <br />meets State Engineer's Office (SEO) performance standards for permeability. During <br />reclamation activities, the clay liner will be monitored for compliance with the SEO performance <br />standard. <br />All reservoir slopes left by the mining operation will be reclaimed to at least 3H:1 V final grade. <br />Reclamation of the exterior cell walls will be concurrent with mining, with reclamation activities <br />following behind the mining operation. Since reclamation will be concurrent with mining, most <br />soil, overburden, and bedrock material excavated during mining will be used almost <br />immediately. Scrapers will be used to place bedrock claystone and overburden material along <br />the reservoir perimeters to achieve the final grade. Upon placing the backfill material, 95 <br />percent compaction will be achieved to insure adequate integrity of the slope. 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 />Inlet and outlet facilities for the reservoir will not be designed at this time until an end user is <br />identified. If an end use of the proposed reservoir has been identified during construction the <br />inlet and outlet could be designed and installed likely resulting in a cost saving. <br />SerFer Project <br />DRMS 112 Permit <br />Page 7 <br />
