12 EXHIBIT E -RECLAMATION PLAN The post-mining land use for the Two River Rock Sand and Gravel Mine permit area will be for awater-storage reservoir with surrounding vegetation producing beneficial wildlife habitat. The lake and surrounding area will be open space as part of a planned unit development proposed by Western Equipment & Truck for the adjoining land it owns. The reclamation plan is presented as follows: Reclamation Process Land disturbance on the permit area will begin with removal and stockpiling of topsoil with a scraper prior to mining. Total disturbed areas (the affected area) can be seen on Exhibit C mining plan. Topsoil will be utilized for future surface reclamation asplant-growth medium. Topsoil stockpile will be located in the Northwest area of the permit site to facilitate easy access for reclamation of the final stage. Temporary revegetation of topsoil stockpile will occur and be maintained until the topsoil is reused in the reclamation process. Reclamation will be concurrent with mining once pit slopes of the outer mining limits are established down to the clay bed. Backfilling of the pit slopes will utilize excess overburden salvaged during mining and will be mixed with weathered shale bedrock removed from the base of the sand and gravel deposit. Two different backfill sections are shown depending on depth of gravel deposit and the use of PVC liner. Exhibit F the Reclamation Plan Map shows these sections and the approximate locations of each. The reclaimed shorelines for the reservoir ponds will slope at 1:3, beginning inward until the slope is complete to the reservoir/pit floor. Exhibit F, the Reclamation Plan Map, shows both a typical final configuration of the reservoir shorelines and across-section through the mined pit-slopes showing how the slopes will be backfilled to final grade. There will be an oversupply of topsoil obtained from the affected area of this mining permit. Topsoil averages 1 foot over the 27 acre area to be stripped and excavated yielding approximately 43,000 cubic yards of topsoil. The Reclamation Plan Map Exhibit F shows that the topsoil requirement as plant-growth medium for the disturbed surface acreage will be approximately 16,400 cubic yards. The required amount of topsoil to be used asplant-growth medium will always be maintained onsite to ensure proper reclamation. Tonsoil Preservation The location of the topsoil stockpiles will be within the permit area and in locations close to final placement asplant-growth medium. Typical topsoil berm locations can be seen on Exhibit C: Topsoil stockpiled in berms for later use in revegetation will be placed on a stable surface within the permit area and will be clearly marked. These topsoil stockpiles will be protected with temporary revegetation from disturbances associated with the mining operation and from wind and water erosion, compaction and other disturbances that would reduce its capability to support permanent reclamation vegetation. The operator will be required to maintain only as much topsoil in storage for surface reclamation as will be required to reclaim the area exposed .The stockpiles will be broadcast seeded with a temporary cover when stockpiles will remain in place 2RR app CDMG 112
