RECLAMATION PLAN EXHIBIT F(CONT) in reclamation. When growth medium/topsoil is removed to reach the mineral deposit, it will be segregated and stockpiled along the north side of the mine . If the topsoil piles remain undis- turbed for more than a year, 40 . 0 #PLS of Western Wheatgrass, per surface acre will be planted on the piles or other means will be employed to preserve the topsoil from wind and water erosion. This will keep it free of contaminants so that it remains useful for sustaining vegetation when reclamation begins . The stock- piles will be located in areas where disturbances by ongoing mining operations will be at a minimum, i .e . along setbacks on the pit perimeter. The topsoil will be handled as little as possible until it is replaced onto disturbed areas . Deep Cut LLC will take measures necessary to insure the stability of the replaced topsoil on graded slopes and ensuring that it is spread as evenly a possible . Fertilizer and other soil amendments will be used, if needed, in accordance with the NRCS recommendations . RECLAMATION TIMETABLE Reclamation will begin once enough area has been opened so that any reclamation completed will not be disturbed as mining progresses . This may take 5 or more years depending on the economic conditions in the area and the amount of material mined. By the time mining is completed approximately 80% of the total mined land will be reclaimed. As mining ends only final back- filling, grading and shaping 350 feet of lake bank will be needed. We expect it to take 6 months to 1 year after mining ends reclamation to be completed. Final seeding will be done during the planting season that follows the completion of resoiling. The area will be monitored for success of revege- tation until accepted by the Division for release . If revege- tation failures occur prior to release, an analysis of the site will be made and the area will be revegetated again as necessary.
