' Banks and Gesso LLC <br />Topsoil Preservation <br />The location of the topsoil stockpiles will be within the permit area and in <br />' locations close to final placement either as backfill or as plant-growth medium. <br />Typical topsoil berm locations can be seen on the Site Plan Map. As the near- <br />vertical pit slopes around the perimeter of the proposed mine pit limits are <br />' completed, topsoil will be used for constructing the final reclaimed slopes into the <br />pit floor in preparation for final grading and revegetation. <br />' Topsoil stockpiled in berms for later use in revegetation will be placed on a stable <br /> surface within the permit area and will be clearly marked. These topsoil <br /> stockpiles will be protected with temporary revegetation from disturbances <br />' associated with the mining operation and from wind and water erosion, <br /> compaction and other disturbances that would reduce its capability to support <br /> permanent reclamation vegetation. The operator will be required to maintain <br />' on{y as much topsoil in storage for surface reclamation as will be required to <br /> reclaim the 20 acres. The stockpiles will be broadcast seeded with a temporary <br /> cover when stockpile~~ will remain in place for more than one growing season and <br />' will be constructed with a minimum 2:1 slope. <br /> Topsoil Placement <br />1 Approximately 1 ft. (1;? inches) of topsoil will be placed on all disturbed level <br /> areas around the reservoir and on all 3:1 slopes, both above and slightly below <br /> the expected high water-line. Contour furrows will be established on the <br /> shoreline slopes to reduce erosion and encourage stable plant growth. Topsoil <br /> will be smoothed-out along the shoreline and furrowed as seedbed preparation <br /> for successful native grass seeding and growth. <br />' <br /> Topsoil spread as plant-growth medium will be spread over ground that has been <br /> smoothed and readiecl for topsoil replacement. Topsoil will not be spread on the <br />' reservoir floor or on the lower portions of the slopes. Due to the loose and <br /> permeable nature of the sand and gravel over the slightly disturbed pit edges <br /> (containing the slurry wall), ripping or scarifying of the disturbed ground will not <br /> be required. Disking of the topsoil may be required due to compaction while in <br />storage, and this will be performed prior to seeding, if necessary <br />' Revegetation <br /> All surface areas disturbed by mining activities will be topsoiled and drill-seeded <br />' for final reclamation with the seed mixes shown in Tables E-1 and E-2. These <br />two seed mixes have been developed, based on recent correspondence (August <br /> 12, 1999) with the United States Department of Agriculture (USDA), who <br />' specified these mixes for another similar site near to this permit proposal. A copy <br />of this correspondence follows Tables E-1 through E-3 in this Exhibit. The seed <br /> mix specified in Table E-3 is for use on topsoil storage berms that will be located <br /> in their positions for a short duration, but will require arapid-growing seed mix. <br />' This mix will be applied to any topsoil berm that will remain for longer than one <br /> year. <br />' <br /> Speer Mining Resource 12 99035 <br />' Asphalt Specialties Company, Inc February, 2000 <br />
