It is apparent <br />that some growth can be achieved as evidenced by old piles on the <br />currently mined areas. It is our understanding that the <br />overburden is a clay loam to sandy clay loam in texture. The <br />operator proposes a series of soil tests be performed to <br />determine if there are any adverse characteristics present in the <br />materials and to compare these materials with the topsoil. In <br />this way a determination can be made as to what type of <br />overburden material is most favorable and if special treatments <br />need to be applied to correct any especially adverse <br />characteristics. With this information, a more precise plan for <br />placement of growth media can be designed. This need is also <br />reflected in the diverse growth patterns of the plant species <br />which invade the various types of soil and overburden piles. <br />(See Exhibit J, Vegetation, for more information on this aspect.) <br />Topsoil will be replaced on the slopes as soon as the overburden <br />has been graded so that erosion of the overburden material will <br />be minimized. The soils are expected to be less erosive. The <br />topsoil will be spread on slopes to a depth of B inches to 10 <br />inches. Excess topsoil, if any, will be placed in pit bottom <br />areas. As backfilling occurs and overburden and soils are added, <br />all slopes will be graded at 4 to 1 or less. <br />It is expected that backfilling, topsoiling and final grading <br />will be accomplished in the first year after mining is complete; <br />however, that may not always be possible. Whenever possible, the <br />operator plans to backfill overburden and topsoil during the <br />months of October through early March (with preference going to <br />17 <br />
