The 3 acre area may be used as a building site for <br />the future owner of the water storage reservoir. The Reclamation Plan assumes <br />the cost for restoration of the mining area as a reservoir and wildlife habitat. <br />Mining Methods <br />The Applicant proposes to dry-mine the majority of the property, with wet-mining <br />methods utilized on tvvo small areas which will be outside the slurry wall <br />alignment. The initial mining will occur near the center of the property, far from <br />neighboring wells, to minimize groundwater impacts on the adjoining properties <br />until the slurry wall is completed. Initial mining operations will include stripping, <br />excavation of dewatering trenches and expanding the existing pond at the <br />southern end of the property for process water systems (subject to low water <br />mining provisions). After the topsoil has been stripped, the raw material will be <br />excavated with front-end loaders. The material may be loaded on a field <br />conveyor in the mining area and conveyed back to the processing area or some <br />materials may be excavated with scrapers or off-road haul trucks. The material <br />near the bedrock may be pushed up with a bulldozer, for subsequent handling <br />with the front-end loaders. <br />The mining sequence proposed by the Applicant dictates that the small area near <br />Old Brighton Road will not be enclosed by the slurry wall, since the disruption to <br />concrete batching and aggregate weighing operations during slurry wall <br />construction would be too great. To eliminate the potential groundwater impacts <br />dry-mining this area could have on nearby wells, the Applicant will wet-mine this <br />area. The plant site will be stripped of any remaining topsoil and overburden. <br />The upper raw materi<~Is will be "benched down" to near the groundwater table <br />with front-end loaders. This technique will allow a large hydraulic excavator to <br />mine the remaining materials to the shale. The wet materials will be windrowed <br />to drain, prior to substquent handling by front-end loaders. Some raw material <br />may be loaded directly into off-road haul trucks for transportation to the <br />processing plant, but these quantities are also expected to be minimal. The <br />Applicant wishes to retain the option of using a dragline to wet-mine the area, <br />which would have the ability to mine to shale from the stripped surface in one <br />pass. <br />Wet-mining operations; would be utilized in Area 3, subject to Low Water Season <br />Mining and Reclamation Procedures described later in this section. Seasonal <br />mining in Area 3 would require concurrent backfill to with three feet of finished <br />grade with shale, and reclaiming the final three feet with topsoil. <br />' Earthmoving Operations <br />Earthmoving operations will begin with general site cleanup, removing fences <br />and incidental agricultural refuse, with appropriate disposal methods. Trees, <br />' shrubs and other excess vegetation will be grubbed and removed, prior to <br />stripping operations. The topsoil first stripped will be initially stored in stockpiled <br />for future reclamation. Stockpiles remaining for over one year will be planted with <br />' Speer Mining Resource 7 99035 <br />Asphalt Specialties Company, Inc February, 2000 <br />1 <br />
