• B~ks and Gesso, LLC <br />Topsoil will be spread evenly over all exposed, disturbed areas for plant-growth <br />medium. The required amount of topsoil to be used as plant-growth medium will <br />always be maintained onsite to ensure proper reclamation. Typical topsoil berm <br />locations can be seen on the Exhibit C-3, Mining Plan Map. <br />Topsoil stockpiles will be temporarily revegetated for protection from <br />disturbances associated with the mining operation and from wind and water <br />erosion, compaction, and other disturbances that would reduce its capability to <br />support permanent vegetation. The stockpiles will be broadcast seeded with a <br />temporary cover when stockpiles will remain in place for more than one growing <br />season and will be constructed with a maximum 2:1 slope. <br />' Backfill generated on site will include waste concrete that has cured for at least <br />six weeks, silts and clays from the washing operation, and non-marketable fine <br />material. Inert fill from off-site may also be brought on site for use as backfill. <br />This material could include concrete fragments, rock, and soil and will be <br />inspected for suitability before acceptance to the site. These backfill materials <br />will be placed along the slopes of the mining cells as they are reclaimed to a 3 to <br />1 slope. <br />The backfill component of reclamation will be concurrent with mining once the <br />near-vertical pit slopes of the outer mining limits are reached. Backfilling of areas <br />in Cell 2 will employ the use of settling fines from processing of on-site materials, <br />as well as overburden materials from the northwest comer. The final grade of <br />the backfilled areas will be graded at 1-2% toward the ponds and wetland <br />ditches. Exhibit F, the Reclamation Plan Map, shows areas back-filled with <br />settling fines, as well as mitigated wetland areas. <br />Topsoil Placement <br />After final grading and backfilling operations are complete, approximately 6 <br />inches of topsoil will be placed on all disturbed areas.
