• <br />CRDA 1 and 2 - The 1994 cut volume represents material salvaged from Pond 6 and adjacent to Topsoil pile 6. The 1994 fill volume <br />and topsoil volumes were not accurately measured but were calculated as the minimum volume required assuming 12" of overburden <br />for CRDA 1, 18" of overburden for CRDA 2 and 6" of topsoil. Actual volumes were greater as indicated by the larger volumes of <br />topsoil and borrow material measured during the same project. <br />CRDA 1 - The 2002 fill volume was calculated as the minimum volume required assuming 18" of cover over area covered measured <br />on a digital map. Remaining cover is that required to coker 0.9 acres. The realignment of Coal Canyon and the reclamation of ponds <br />6 and 10 has a material deficit of 20,640 cubic yards. This material will be borrowed from topsoil pile number 2, the e>cess material <br />generated from the realignment of Coal Gulch and reclamation of Pond 11 and topsoil pile number 1. <br />CRDA 2 - The 2002 fill volume was calculated as the minimum volume required assuming 18" of cover and 6" of topsoil over the area <br />covered measured on a digital map. Devalopment of the upper diversion ditch generated approbmately 10,000 cubic yards. The <br />remaining 13,877 cubic yards were borrowed from Coal Canyon between the upper dip section and the large diameter culverts <br />located under haul road number 4. The small amount of material borrowed from CBA -1 is not included in yardage estimates. <br />South Fan - The volumes and areas were taken from TR -01 reclamation estimates. The stockpiles resulting from the construction did <br />not qualify as topsoil therefore for topsoil volumes in the TR are included in this fill volume. <br />2 West Portals - Volumes and areas were taken from TR -14 reclamation estimates. <br />Cameo Borrow Area 1 - The 1994 salvaged volume was measured from before and after contours and the topsoil volume was <br />estimated. Areas were taken from measurements on topo maps. <br />Cameo Borrow Area 2 - The 1994 salvaged volume was measured from before and after contours and includes approxmately 600 <br />C.Y. of material remaining in a temporary stockpile at the site. The 2002 salvaged volume is assumed to equal the estimated amount <br />of material placed on CRDA-1. The reclamation pond 11 and the work on Coal Canyon is projected to have an excess cut of 9,609 <br />cubic yards which will be utilized for the reclamation of Ponds 6 and 10. <br />Roads - Roads scheduled for reclamation are included in projections for operations areas. <br />Existing reclamation - This represents reclamation work done on the site to date. The greater volume of cut and salvaged material <br />compared to the filled and topsoil volumes indicates the extra volume of material placed on CRDA 1 and 2 in 1994. <br />Proposed Reclamation - This represents reclamation work yet to be done. The greater volume of cut and salvage material compared <br />to the fill and topsoil volumes give a small cushion for extra material. <br />Table 14-1 Page 3 of 3 07/06 <br />
