MINING PLAN EXHIBIT D (cont) Drainage ditch (abandoned). The dredge is capable of mining to depths of 60+ feet. Mining will continue along this face until all material is removed from Stage I. When it comes time to move south of the ditch a 5 acre area will be stripped of growth medium and a trackhoe will be used to open a shallow lake where the dredge will be set. Mi then proceed as described above but how the mine face will be determined at that time. Map Exhibit C -1 Min shows how the site may look as mining is progressing ing will is worked ng Plan Map n Stage I. Under normal conditions 60 to 80,000 tons of material will be stockpiled during a mining session. When adequate material has been stockpiled the dredge and processing plant w1.11 be moved to the next mine. Material will be removed from the stockpiled material over a 2 to 4 year period as needed and once the stock- piles are exhausted the mining cycle will begin again. A new area will be stripped as needed and the growth medium will be stockpiled around the perimeter of the lake area for use in reclamation. Mining equipment may include but is not limited to, a gravel dredge and it's auxiliary equipment, front -end loaders, scrapers, track hoes, bulldozers, conveyors, dump trucks and a water truck. There are 46.82 acre ± in the affected lands, 42.18 acres ± will be disturbed as part of the mining operation. Please refer to the Mining Timetable on page 15 for the estimated acreage of each area associated with the mining part of this operation. The amount of land disturbed at one time will be limited to 7.22 acres ± that will be used for processing and stockpile area (PlantSite); 3.00 acres ± stripped pre- mining area and the actual mined area. At any given time no more than 5.00 acres ± will need to be revegetated. This means that there will be no more than 16.00 acres ± needing reclamation at any one time. Note that any area covered by water needs no reclamation except in a narrow band below water, around the lake shore where slopes have to be established to no greater than 3h to lv from 5 foot above to 10 feet below the water line. The PlantSite area will not be mined since this area was part of an old pre -law mine that has been backfilled. It will be utilized throughout the life of the mine to accommodate the processing equipment for the gravel operation and may serve as a site for auxiliary uses. These uses may include an asphalt batch plant, and a concrete batch plant, both subject to County ap- proval. The exact layout of these plants is unknown at this time. That information will be supplied to the Divisions prior 9
