• ~ks and Gesso, LLC EXHIBIT E -Reclamation Plan Overview The post-mining land use for the Stagecoach Mine will be a lined water-storage reservoir, with surrounding riverside areas producing beneficial wildl'rfe habitat. The Reclamation Plan assumes the cost for restoration of the mining area as a lined reservoir and wildlffe habitat. Reclamation Process Land disturbance on the permit area will begin with removal and stockpiling of topsoil with a scraper prior to mining. Total disturbed areas (the affected area) can be seen on Exhibit C-3, Mining Plan Map. Topsoil will be utilized as plant- growth medium for future surface reclamation in areas that will not be permanently covered by water. Topsoil stockpile berms will be located around the permit site to mitigate sound impacts. Temporary revegetation of topsoil stockpiles will occur if a stockpile is left undisturbed for more than one growing season and will be maintained until the topsoil is reused in the reclamation process. Reclamation will be concurrent with mining once the pit slopes of the outer mining limits are established down to the shale bed. Backfilling of the pit slopes will utilize excess topsoil salvaged during mining. Shale bedrock excavated from the base of the sand and gravel deposit will also be used. The reclaimed shorelines for the reservoir ponds will slope at 3:1, beginning inward until the slope is 10 ft. below the maximum capacity for the designed reservoir water level. From this point downward to the pit floor, a 2:1 slope will be utilized. Exhibit F, Reclamation Plan Map, shows both a typical final configuration of the reservoir shorelines and across-section through the mined pit-slopes showing how the slopes will be backfilled to final grade. There will be an oversupply of topsoil obtained from the affected areas of this mining permit. Overburden averages 2.3 feet over the 32.5-acre area that will be stripped and excavated. The reclaimed shoreline and backfilled areas amount to approximately 32.5 acres. Excess topsoil will be used with weathered-shale bedrock excavated from the pit floor to construct the sloped pit-walls. The pre- mining process will salvage approximately 28,000 cubic yards of topsoil during the mining process. It is estimated that an additional 110,000 cubic yards of overburden will be salvaged. Overburden, shale, and excess topsoil will be used to barkfll and create the slopes of the reclaimed pit walls. The Operator will incorporate additional backfill to create a more naturally appearing shoreline at the reclaimed site, if needed. Exhibit F, the Reclamation Plan Map, shows the typical shorelines that will be created by final reclamation of the mining site. The required amount of topsoil to be used as plant~rowth medium will be maintained onsite to ensure proper reclamation.
