i 1 0 9 <br />Table 14-1 Notes: <br />Permanent Flood Control Dike - Volumes and area taken four TR -02 proposed design. Material borrowed from a sand/gravel bar in <br />the Colorado River, <br />South Lease Exploration - Volumes assumed using 1 ' oftopsoil salvaged and replaced on all roads and pads disturbed. Actual <br />volumes unknown. Areas taken from TR -04 and MR -10 design for the project. <br />North Decline - Volumes taken from calculations for contractor payment. Areas were taken from measurements on topo maps. <br />Roadside South Portals - Remaining cut and fill volumes were calculated with the use of digital maps of existing and post mining <br />topography and SurvCADD 2006. See Exhibit 6C for Post Mining Topography. Difference between cut & fill is 29,000 CY. Deficit will <br />be made up with material from the Unit Train Loadout. <br />RSRDA - The Cut Volume is the amount of refuse excavated to create the two 15 -foot wide benches. Fill volume includes the cut <br />volume and the volume of cover material placed on the slopes. The RSRDA slopes cover volume includes dirt on the pile that was <br />moved to allow installation of benches on the upper part of the pile. The RSRDA topsoil volume represents the amount of topsoil to <br />be salvaged and replaced in the borrow area. <br />Overland Conveyor and Railroad Spur - The cut and fill volume and area were taken from 1982 reclamation estimates and include <br />grading out the road and track bed as well as filling the holes at the transfers. The topsoil estimate represents the wlume of the <br />existing stockpile. This volume will cover a 2400' stretch of the road and railroad 80' wide with 6" of topsoil and 4000' of conveyor 40' <br />wide with 6" of topsoil. <br />Unit Train Loadout - The areas were measured on topo maps. The volumes were calculated using'average end areas' on cross <br />section on 100' centers. See Exhibit 59 for the cross sections and the approzmate cut and fill areas of each. Quantity reduced by <br />36,000 CY to account for deficit at Road Side South Portal. <br />Roadside North Portal - The areas were measured on topo maps. SurvCADD was used to calculate the cut and fill volumes with the <br />use of digital maps of existing and post mining topography. See Exhibit 8C for Post Mining Topography. The topsoil volume was <br />calculated assuming 6" over the measured area. The volume of material required to reclaim pond 13 was calculated from digital topo <br />maps and it will be borrowed from Topsoil Pile Number 1. <br />Table 14-1 Page 2 of 3 07/06 <br />
