Topsoil, approximately 1.5 ft., will be cleared from the north end of the permit area to create an <br />area to deposit the reject rock material as part of contemporaneous reclamation. The salvaged <br />topsoil will be in the proposed stockpile area on the west end of the permit area. <br />Item 3 Exhibit D - The Mining Plan Rule 6.4.4 <br />The improvements to the access road are in the immediate area where vehicles turn onto the <br />access road off Last Dollar Road. The first 100 feet of road will be paved and then the road will <br />be gravel up to the first gate (#7), a distance of approximately 1/2 mile. These road improvements <br />are conditions included in the Special Use Permit approved by the Board of County <br />Commissioners. These localized improvements are intended to control dust in the vicinity of and <br />the tracking of mud onto Last Dollar Road. <br />Topsoil is present within the new permit area and a portion will be salvaged for reclamation. <br />The response to the reclamation plan review will contains the answers concerning topsoil depths, <br />salvaging, stockpiling and placement as part of reclamation. <br />There are two fuel tanks on site, 500 gallon diesel and 500 gallon unleaded fuel. These tanks will <br />be provided with impermeable secondary containment with a storage volume that is 110% of the <br />rated tank capacity. These tanks are located to the right of the access road as it enters the permit <br />area. <br />TSC understands that its mining permit remains valid as long as there is a resource to process <br />and/or quarry, reclamation needs to be completed and the operation is in compliance with its <br />permit terms. <br />Item 4 Exhibit E - Reclamation Plan, Rule 6.4.5 <br />The questions regarding topsoil depth, salvaging, stockpiling, and placement during reclamation <br />from Item 3 are answered in this response. <br />TSC personnel dug 5 soil profiles to determine the presence of and the depth of topsoil. The <br />topsoil depth ranged from 3.5 to 6 feet, with the average being 4.6 feet. The locations of these <br />soil test pits are shown on Exhibit F Reclamation Map. <br />The following contemporaneous reclamation sequence will be used to place material along the <br />northern permit boundary adjacent to the 7:1 slope constructed as part of the TRAA runway <br />improvement project. <br />Salvage topsoil from areas where the stockpiled stone has been removed and along <br />the northern boundary beginning on the western end. An area will be cleared of <br />topsoil to a depth of 2 feet annually to accommodate the waste material produced <br />each year. <br />2. Salvaged topsoil will be placed in the stockpile area on the western edge of the permit <br />area. <br />3. Waste material will be placed in these cleared areas to a maximum height of 8 feet <br />above the surrounding existing grade or to the top of the airport boundary fence. <br />4. The salvaging of topsoil and placement of waste material from the stone processing <br />operation will continue from west to east until all the stockpiled 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 />complex world) CLEAR SOLUTIONS <br />2 <br />
