~~ <br />J <br />Banks and Gesso, LLC <br />restoration of the mining area as two connected reservoirs and wildlife habitat. <br />Wetland vegetation lining the current Lupton Bottom Ditch will be removed due to <br />mining-through the ditch, but will be replaced with wetland grass-seeding and by <br />eventual natural invasion and establisment of wetland plants at the shorelines of <br />the reservoirs <br />Mine Plan <br />Prior to the commencement of mining, the applicant will construct a slurry wall <br />keyed into the shale bedrock, surrounding the area to be mined and located <br />approximately 15 ft. within the permit area boundary. The slurry wall will act as a <br />barrier to offsite alluvial groundwater impacts caused by the drawdown of <br />groundwater within the pit area facilitating "dry mining" of the site. The slurry wall <br />will also act to isolate surrounding groundwater from interacting with decreed <br />water rights to be used for reservoir storage water upon final reclamation. Near <br />the close of Phase 1 of the mining process, the length of the Lupton Bottom Ditch <br />on the permit site will be re-routed approximately 175 ft. to the east during the <br />winter no-flow period, with approval from the Lupton Bottom Ditch Company and <br />authorization through a U.S. Amy Corps of Engineers 404 permit (if required). <br />An agreement is being finalized with the ditch company and a draft is contained <br />within Exhibit S, along with a draft of an agreement being developed with the oil <br />and gas operating company, should the pipelines need to be relocated. The <br />ditch location will be mined-through in two phases, subsequently reconstructed <br />with excess topsoil and shale bedrock and replaced to its original surveyed <br />grade.
