The reclamation plan calls for returning the disturbed areas, after mining and reclamation, to <br />a land use that is rangeland. This land use is consistent with that found in the surrounding <br />area. <br />The predominate feature of the reclaimed area will be a flat graded area approximately 60 <br />feet below the surrounding undisturbed elevation. A Reclamation Plan Map depicting the <br />configuration of the ground surface area, which will result after the gravel resource has <br />been removed, is enclosed as Exhibit F. <br />BACKFILLING AND GRADING -As described in the Mining Plan, backfilling and grading <br />will occur on an ongoing basis for the area added in 2002. It is anticipated that backfilling <br />and seeding will occur at 2 to 3 year intervals until the site has been completely mined. As <br />the gravel extraction activities are completed, the backfilling and grading activities will <br />commence on the final cut in the southwest part of the permit area (approximately 4 acres). <br />The backfilling and grading sequence will be as follows: <br />1. The stockpiled overburden will be hauled by scraper from a centrally located <br />stockpile area by mobile equipment to the extraction site and placed where required <br />to achieve a level topography and properly backfilled slopes. The main stockpile is <br />located in the easternmost portion of the disturbed area although the pile may <br />change slightly in dimension during the remaining life of the pit. <br />2. Backfill will be graded to proper slopes using dozers or similar equipment. All <br />slopes will be graded no steeper than a ratio of a 3 foot horizontal to 1 foot vertical <br />slope. Grading will be done by dozers and scrapers which will compact and stabilize <br />the overburden material. To insure stability of the slopes, material will be placed in <br />12 inch lifts and compacted to a minimum density of 85 percent maximum dry <br />density. It is estimated that 98,000 cy of overburden will be needed to backfill the <br />highwalls at the end of mining. As described in the mining plan, 28,000 cy of naturals <br />will also be needed to complete the backfilling and grading. The final grade of the pit <br />bottom will be 2% or less to the south. <br />3. The sediment pond dam material (3' height) will be removed with a dozerand placed <br />in the 0.5' incised portion of the pond, which will configure exactly to the final grade <br />of the site. This dam material will then be covered with topsoil and seeded as <br />described in this section. The total quantity is less than 170 cubic yards and will be <br />done as part of the backfilling operation. <br />Topsoil or overburden may at times be brought to the site from outside areas. To insure that <br />all the material delivered to the facility from outside areas is clean and inert, the following <br />procedure has been implemented: <br />The individual or company delivering material to the facility is required to sign an <br />affidavit certifying that the material is: clean and inert, naming the originating source <br />
