2.05.4 Reclamation Plan. <br />(2) (d) (Cont'd) j <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 otherimaterials shall not be moved until required for <br />redistribution on a disturbed larea. 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 ink the Soils Appendix, Volume 9 for the present <br />locations of topsoil storage areas. <br />Final Redistribution of Topsoil <br />I <br />West Mine 1 <br />i <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 />• 1 <br />There is no topsoil available to plate the areas that will be disturbed during <br />removal of Ponds W-1, W-2 and the removal of the East Roatcap Creek <br />culvert. <br />i <br />East Mine 1 <br />I <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 pot was removed. The area was apparently <br />reclaimed again during the summer of 1988. <br />The new waste disposal area was plated with 8 to 9" of topsoil during <br />contemporaneous reclamation activities. <br />i <br />Topsoil was removed and contemporaneously replaced during <br />construction of the Orchard Valley Mine water pipeline. <br />I <br />TR-48 62 07/08
