sandstone occurs. If a decision is made to quarry the sandstone, then this reclamation <br />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 project <br />through the processing operation; and <br />2. Staging of stone processing waste material along the northern permit boundary. <br />The proposed post mining contours for the processing area are shown on the revised Exhibit F - <br />Reclamation Map. The calculations to determine the depth of topsoil to remove and the topsoil <br />stockpile and stone waste storage areas are also attached. <br />The post mining contours have been added to the Reclamation Map. The stone processing waste <br />material available is: <br />Estimated Stockpile Volume - 50,000 cu. yds. <br />Historic Reject % 40 <br />Stone Processing Waste Volume - 20,000 cu. yds. <br />The post mining contours assume no quarrying will occur after all the stockpiled stone is <br />processed. The post mining contours will be revised as part of a permit revision if a decision is <br />made to quarry the Dakota sandstone after the stone processing is completed. The revised <br />Exhibit E is attached. <br />Item 5 Exhibit F - Reclamation Map, Rule 6.4.6 <br />The reclamation map has been revised to show the stone processing waste material and topsoil <br />stockpile areas and the proposed post processing contours. The revised exhibit is attached. <br />Item 6 Exhibit I - Soils Information, Rule 6.4.9 <br />The information on the soil depth has been removed and a reference to Exhibit E for topsoil <br />depth present added. The NRCS soils maps are meant to depict regional trends for soil <br />classifications. Since local variations can occur from those reported in the soil study, TSC <br />elected to dig soil test pits to determine the amount of topsoil present. These values are used in <br />the reclamation plan and exceed those reported in the NRCS soil study. The revised Exhibit I is <br />attached. <br />Item 7 Exhibit J - Vegetation Information, Rule 6.4.10 <br />The weed control plan has been revised to state "treated per the Weed Control Plan in Exhibit D <br />Mine Plan." <br />The revised Exhibit J is attached. <br />Item 8 Exhibit L - Reclamation Costs, Rule 6.4.12 <br />TSC has no comment on the reclamation bond cost and the potential for a different amount at <br />this time. TSC will respond with alternate ways to reclaim the site when the Division's bond <br />estimate is completed. <br />complex world } CLEAR SOLUTIONS <br />3
