16.2 Topsoil Salvage Thickness - 19956 Study Area <br />This study addresses the additional permit area immediately east of 2700 Road and south of BB <br />Road, which is an area of 105.8 acres. See Map 2.04.9 -1 for the boundary of this area. At the <br />conclusion of Pase 6 topsoil removal campaign (12- 20 -95), WFC conducted a topsoil balance study <br />for the approved permit boundary. The study included the entire New Horizon 2 mining area. The <br />remaining undisturbed acreage that topsoil will be salvaged from plus the topsoil that was placed <br />in topsoil stockpiles at the beginning of mining was taken into account. All disturbed acreages were <br />taken into account. The conclusion of this study can be seen in Table 2.04.9 -6. <br />The study shows that New Horizon 2 will be topsoil deficient in Lift A of the two lift irrigated pasture <br />reclamation portion. This Lift A has typically come from the first lift of the 30C soil group. To correct <br />this shortage, WFC will substitute excess soil type 808 from the major drainage directly north of <br />Pond 007 for Lift A. During Phase 6 topsoil campaign, 2.4 feet of 808 soil was removed from the <br />drainage area and used for mixed topsoil replacement. The soil map shows the 808 depth being <br />2.4 feet in the drainage area. There is more 808 to be salvaged. The 808 soil looks good and <br />should make great Lift A material. WFC will test the remaining 808 to verify its quality.as <br />done in the Annual Reports submitted tothe Bivis'an, which shavved thatthis matehal was suitable <br />as subseH7 As of February 2008, these areas have been fully reclaimed to the topsoil thickness <br />shown on Map 2.05.4 -4. <br />Initially, it was reported that an area of approximately 6.73 acres immediately east of Mount Nucla <br />(box cut overburden stockpile) was only covered with 0.8 feet of topsoil. This was incorrect. The <br />postmine topsoil replacement map, Map 2.05.4 -4 shows the actual replacement, which is 18" of <br />Lift A and 27" of Lift B. <br />August 2013 (PR 08) 2.04.9 -39 <br />
