<br />Topsoil segregation, preservation and replacement; <br />Topsoil shall be removed and segregated from other spoil. For reclamation, topsoil will be replaced <br />by a scraper and generally graded with a blade. All grading shall be done in a manner that controls <br />erosion and siltation of the affected lands, to protect azeas outside of the affected land from slides <br />and other damage. In addition, all backfilling and grading shall be completed as soon as feasible <br />after mining. <br />Topsoil will be replaced on all azeas above the anticipated high water line. The minimum thickness <br />shall be 12 inches above the surrounding finished grade. The topsoil shall be keyed to the <br />underlying and surrounding material by the use of harrows, rollers or other equipment suitable for <br />the purpose. <br />Revegetation <br />[n an unaltered creek system, periodic creek flooding regenerates Cottonwood communities by <br />scouring the baze mineral soils and simultaneous prolonged high water level at the time of <br />Cottonwood seed dispersal. Aggregate will scarify bare mineral soil along the shoreline wetland <br />benches in late spring. This will help emulate the effects of flooding and stimulate the establishment <br />of native trees. This method has been studied by a Colorado Division of Wildlife Research Team <br />and has been successful on other projects. Please refer to Exhibit E -Reclamation Plan (e) for <br />further details on revegetation. <br />Reclamation Schedule <br />Mining Schedule <br />Section Being Mined Timing Estimate <br />Pod # t 9 months to mine <br /> 12 months to reclaim <br />Pod #2 6 months to mine <br /> 12 months to reclaim <br />Pod #3 l5 months to mine <br /> 12 months to reclaim <br />Pod #4 l4 months to mine <br /> l2 months to reclaim <br />Pod #5 8 months to mine <br /> 12 months to reclaim <br />Pod #6 l4 months to mine <br /> 12 months to reclaim <br />Please note that the above schedule is an estimate based on the current mazket conditions.
