Banks and Gesso, LLC <br />once the pits are allowed to refill. From this point to the pit floor, slopes will be at a 2:1 <br />ratio. Mine Area 2 pit edges will be mined at a 5:1 slope, leaving the desired post-mining <br />slopes in place. No backfill will be needed in Mine Area 2. Water levels are expected to <br />be approximately 3 ft below existing grade on the site. Approximately 16 inches of <br />topsoil will be re-spread over all Phase 1 disturbed areas above water levels. <br />To reclaim the site, approximately 211,000 yd3 of material will be required to backfill the <br />Mine Area 1 pit edges to the proposed slopes. Then, approximately 3,400 yd3 of topsoil <br />will be re-spread over all disturbed land above water level (approximately 1.6 acres). <br />Additional material in the form of waste fines can be made available should additional fill <br />material be necessary. No imported material will be needed to complete reclamation. <br />Topsoil Replacement <br />After overburden replacement in Phase 1, approximately 16 inches of topsoil will be re- <br />spread over disturbed areas (above water levels) to provide a proper medium for <br />revegetation. Topsoil will not be re-spread when the ground is frozen, excessively wet <br />or otherwise unsuitable. Contour furrows will be established on shoreline slopes to <br />reduce erosion and encourage stable plant growth. Soils that are excessively <br />compacted will be chiseled or disced to break up compaction, then harrowed down. <br />Revegetation <br />All surface areas above water levels (approximately 1.6 acres), disturbed by Phase 1 <br />mining activities, will be topsoiled and drill-seeded for final reclamation with the seed <br />mixes shown in Tables E-1 and E-2. If use of a grass drill is not possible, seed <br />broadcasting will occur at double the seeding rate. These seed mixes have been <br />developed based on correspondence with the United States Department of Agriculture <br />(USDA), who identified these mixes for use on a similar site near this proposed project <br />area. The seed mix specified in Table E-2 is for use on topsoil storage berms and other <br />areas requiring a rapidly growing seed mix. <br />Maintenance <br />Mowing in Phase 1 will be performed for at least 2 years following seeding to help <br />establish regenerating stands of grasses and to control weed infestation.
