1 <br /> ' Prior to topsoil replacement in the North Mining Area, a scraper will smooth-out <br /> ' any rough ground in the setback and lakeshore areas in preparation for growth <br /> medium placement. <br /> 1 <br /> ' In the South Borrow Pit Area, a loader will be used to backdrag the 2:1 slopes <br /> ' leading to the pit floor. Prior to growth medium replacement, a scraper may be <br /> used to smooth out any rough areas. <br /> Exhibit D shows final reclamation contours in both mining areas. The South <br /> Borrow Pit Area shows 2:1 contours leading to the pit floor from the edge of the <br /> excavation. The North Mining Area shows final reclamation contours of 3:1 and <br /> ' 2:1 leading from the setback areas (level) into the base elevation (approximately <br /> 4,002 ft.) of the lake floor. <br /> ' Topsoil Replacement: <br /> In both mining areas (North Mining Area and South Borrow Pit Area), <br /> topsoil/overburden will be re-spread over the disturbed ground to a minimum <br /> ' depth of 12 inches with a scraper. <br /> ' The growth medium will be spread over ground that has been smoothed and <br /> readied for topsoil replacement. Due to the loose and permeable nature of the <br /> ' sand and gravel at the mining locations, ripping or scarifying of the disturbed <br /> ground will not be required. Disking of the topsoil may be required due to <br /> ' 22 <br />
