K I•r <br />EXHIBIT E - RECLAMATION PLAN <br />As TSC works through the stockpiled material, there will be unsuitable material that will <br />be set aside on the northern border of the permit area. It will be placed as backfill to <br />continue the existing 7:1 slope that stretches from the edge of the RSA to the north <br />boundary of the permit area. The estimated volume of unsuitable material is: <br />Estimated Stockpiled Sandstone Volume - 50,000.00 cu. yds. <br />Historic Reject Rate _ 40% <br />Estimated Unsuitable Material - 20,000.00 cu. yds. <br />The 7:1 slope will be extended to a height of 6 feet above the existing ground. On the <br />east, south and west boundary a 3:1, H:V, slope is extended from the crest of the fill to <br />the existing ground. <br />TSC personnel dug 5 soil profiles to determine the presence of and the depth of topsoil. <br />The topsoil depth ranged from 3.5 to 6 feet, with the average being 4.6 feet. The <br />locations of these soil test pits are shown on Exhibit F Reclamation Map. <br />The following contemporaneous reclamation sequence will be used to place material <br />along the northern permit boundary adjacent to the 7:1 slope constructed as part of the <br />TRAA runway improvement project. <br />1. Salvage topsoil from areas where the stockpiled stone has been removed and <br />along the northern boundary beginning on the western end. An area will be <br />cleared of topsoil to a depth of 2 feet annually to accommodate the waste <br />material produced each year. <br />2. Salvaged topsoil will be placed in the stockpile area on the western edge of <br />the permit area. <br />3. Waste material will be placed in these cleared areas to a maximum height of 8 <br />feet above the surrounding existing grade or to the top of the airport boundary <br />fence. <br />4. The salvaging of topsoil and placement of waste material from the stone <br />processing operation will continue from west to east until all the stockpiled <br />stone is processed. <br />5. Reclamation of the stone stockpile and processing area will be done the year <br />following cessation of the processing operation if no quarrying of the Dakota <br />sandstone occurs. If a decision is made to quarry the sandstone, then this <br />reclamation plan will be revised to reclaim the quarry area. <br />Contemporaneous reclamation includes the following activities: <br />1. Removal of the stockpiled sandstone from the TRAA runway improvement <br />project through the processing operation; and <br />2. Staging of stone processing waste material along the northern permit <br />boundary. <br />The estimated volume of reject material available for reclamation is shown in Table 1 <br />below. An allowance for additional topsoil to allow infiltration of soil into the void <br />spaces of the waste rock has also been included. <br />Revised 5110111
