RN-08 62 03/23 <br /> <br />2.05.4 Reclamation Plan. <br /> <br />(2) (d) (Cont-d) <br /> <br />surface considering drainage, erosion and flood plain, shall be selected for <br />its placement. After placement in the stockpile, the stockpile will be <br />revegetated according to the Revegetation Plan in Section 2.05.4(2)(e). <br />Stockpiled topsoil and other materials shall not be moved until required for <br />redistribution on a disturbed area. See Maps 8-1, 6A-2A through G, Map <br />8-6, 8-7 and the Orchard Valley West Mine Portal Topsoil Placement and <br />Sediment Control drawing in the Soils Appendix, Volume 9 for the present <br />locations of topsoil storage areas. <br /> <br />Final Redistribution of Topsoil <br /> <br />West Mine <br /> <br />There were three topsoil stockpiles at the west mine. One was located at <br />the west mine fan level. A second was located north of the west mine <br />portal. Both topsoil stockpiles are shown on Map No. 8-7. The third <br />pile/storage area was the topsoil that plated the outslopes of the west <br />mine fill embankment. It is estimated that 32” of topsoil were replaced at <br />the west mine fan level. It is estimated the remaining portion of the <br />regraded west mine was plated with six to nine inches of topsoil salvaged <br />from second and third stockpiles. <br /> <br />Topsoil from near the shaft will be used to plate the areas that will be <br />disturbed during removal of Ponds W-1, W-2 and the removal of the East <br />Roatcap Creek culvert. <br /> <br />East Mine <br /> <br />The old waste disposal area near Ponds 1 and 2 was reclaimed during <br />August 1983. There is no record of the depth of topsoil placed on the pile. <br />It is noted that only the top of the pile received topsoil. In the spring of <br />1985, spontaneous combustion was detected. Topsoil and cover material <br />were excavated and the hot spot was removed. The area was apparently <br />reclaimed again during the summer of 1988. <br /> <br />The new waste disposal area was plated with 8 to 9” of topsoil during <br />contemporaneous reclamation activities. <br /> <br />Topsoil was removed and contemporaneously replaced during <br />construction of the Orchard Valley Mine water pipeline. <br /> <br /> <br /> <br />
