EXHIBIT E <br /> Reclamation Plan <br /> A lined water storage reservoir will be the final reclaimed use for the Bernhardt Sand and Gravel <br /> Pit. Portions of mining area will be reclaimed as"native"areas,which will be re-seeded with native <br /> vegetation. The majority of the mining areas will be reclaimed as a water storage reservoir. The <br /> remaining area within the proposed permit boundary will consist of reservoir shoreline, <br /> unimproved access roads around the reservoirs, and reclaimed vegetated land. <br /> Final Land Use Reclamation <br /> Plan Area <br /> acres <br /> Reservoir Water Surface 92.35 <br /> Access Roads 3.59 <br /> Reclaimed Vegetated Land (Disturbed Land 15.07 <br /> and Slopes above Reservoir Water Surface <br /> TOTAL 111.01 <br /> Water Storage Reservoir <br /> In general, the mining limits will be mined down to the shale/claystone/sandstone bedrock. The <br /> relatively impermeable bedrock will make the bottom of the reservoir. The reservoir will be <br /> separated from the surrounding alluvial aquifer by the slurry wall liner system as detailed in the <br /> cross-section shown on the Reclamation Plan Map. The slurry wall liner will be keyed into the <br /> bedrock material and extend upward through the height of the alluvium as depicted in the mining <br /> plan. Design specifications and quality control procedures used during the construction of the <br /> slurry wall liner will ensure that the reservoir meets the State Engineer's Office(SEO) performance <br /> standards for permeability. <br /> All reservoir slopes will be reclaimed to at least 4.51­1:1V final grade Since reclamation will be <br /> concurrent with mining, most soil, overburden, and bedrock material excavated during mining will <br /> be used almost immediately. Scrapers and dozers and compactors will be used to shape the <br /> reclaimed slope material along the reservoir perimeters to achieve the final grade. Upon placing <br /> the backfill material, 95 percent compaction will be achieved to ensure adequate integrity of the <br /> reclaimed slope, backfilled areas for haul/access roads and recharge pond areas that are not <br /> within the future water storage/reservoir footprint. Final reclamation by capping with topsoil and <br /> re-vegetating above the expected reservoir water level will follow grading operations as well as <br /> backfilled areas that will not be haul/access roads to minimize the amount of disturbance at any <br /> one time. <br /> Recommendations for monitoring of slope stability, including, conducting a visual inspection of <br /> the excavated slopes on a weekly basis for the duration of mining, conducting a visual inspection <br /> after a major precipitation event that has saturated the ground using the same procedures, <br /> contacting qualified personnel to evaluate and recommend remediation work to stabilize the area <br /> in the event a visual inspection detects signs of potential slope failure, and if no visible signs of <br /> slope failure are detected during mining, reducing visual inspections to once every six months <br /> after mining completion, or after every major precipitation event. <br /> IHC Scott,Inc. <br /> J&T Consulting,Inc.
