RECLAMATION PLAN EXHIBIT E <br />1. GENERAL RECLAMATION PLAN <br />The reclamation plan calls for creating a lake to wildlife habitat and utilizing the flat staging area <br />for industriaUcommercial use. The predominant feature of the reclaimed area will be a 50 acre lake <br />with 3H:1 V sidestopes and wetlands along the water surface. The 8.0 acre staging area will be left <br />graded flat for an industrial site. Exhibit F shows the final configuration of the site. Since 30% of <br />the raw material will be naturals (fines) that will not be sold, the lake bottom will be filled with <br />these fines and the expected average depth of water after filling is only 6-7.5 feet. See Map C-3 <br />cross section for details. <br />As each of the Phase extraction areas are completed, the backfilling and grading activities will <br />commence, except for the working gravel face(s). In this way, much of the reclamation of previous <br />phases will be done on an ongoing basis. The stockpiled overburden will be hauled from its storage <br />area located adjacent to the extraction area by mobile equipment and placed where required to <br />achieve a level topography and properly backfilled slopes. All slopes will be re-graded no steeper <br />that a ratio of 3:1 (horizontal to vertical). Grading will be done by dozers or other equipment which <br />will compact and stabilize the overburden and naturals in their final configuration. Selective han- <br />dling or placement of overburden materials will not be necessary. <br />2. TOPSOIL REPLACEMENT <br />As described in the Mining Plan, approximately 9680 cy of soil is available from the area of the <br />sediment pond, It will be salvaged prior to mining and will be used in lining the lake edge to en- <br />courage wetland development. The expected lake surface elevation is 4450 feet. At this level, the <br />lake perimeter is approximately 7454 feet. From 5 feet below water level (at the 3:1 angle) to the <br />top of bank is approximately 48 feet length which will be topsoiled. This requires a volume of 9680 <br />cubic yards using a replacement depth of 8-9 inches. Since 9680 cy is available from the topsoil <br />stockpile, the design will work. <br />Gilsoni[e Pit 10/02 16 <br />
