• "first annual topsoil balance requirement" as stipulated in Nucla Permit Revision No. 1. <br /> Three significant modifications were incorporated into the February 29, 1988 topsoil <br /> balance. First, Mine Area 5 was omitted from the life-of-mine operation. Second, Topsoil <br /> Stockpile 1 and most of the disturbed land associated with Mine Area 4 was proposed to be <br /> excluded from the permit area and turned over to Montrose County per Technical Revision <br /> No. 2 (pending). Lastly, topsoil handling activities for Mine Area 1 were expanded to <br /> include the temporary bypass road, topsoil underlying Stockpile 5, and ahead-of-mine <br /> topsoil salvage between the temporary bypass road and proposed Topsoil Stockpile 13. <br /> Two significant changes are incorporated into this July 1988 topsoil balance. First, the <br /> topsoil salvage area for the former Topsoil Stockpile No. 5 is included in the disturbed <br /> land category. Second, topsoil handling activities for Mine Area 1 are expanded to <br /> include topsoil underlying Topsoil Stockpile No. 13 and additional ahead-of-mining topsoil <br /> salvage above the NE/SW highwall between Topsoil Stockpile Nos. 8 and 13. Topsoil <br /> Stockpile No. 1 and Mining Area No. 4 are still shown on Exhibit 21-1 and 21-2 until <br /> Montrose County completes the landfill licensing procedures and Technical Revision No. 2 <br /> is approved in its entirety (i.e., both change in land use and release of liability are <br /> • approved). For purposes of this topsoil balance, topsoil requirements for Area No. 4 are <br /> included. Topsoil Stockpile (TS) No. 1 is included in the topsoil stockpile volumes <br /> (Tables 9-3-1 and 9-3-2). However, since TS 1 is dedicated for reclamation of the <br /> temporary bypass road leading to the existing landfill, and since Montrose County has <br /> requested that the temporary bypass road and TS 1 be retained for their use, the volume of <br /> topsoil in TS 1 is not included in the replaced topsoil depth calculations. <br /> Stockpiled Topsoil Reserves. All existing (10 total) and proposed (2 total) topsoil <br /> stockpile locations are shown on the enclosed Topsoil Balance Plan, Exhibit 21-1. All <br /> existing topsoil stockpiles are clearly marked with appropriate signs. There has been no <br /> change in the volume of topsoil at seven stockpile locations (1, 2, 3, 4, 6, 7, and 8) <br /> since October 1983. These topsoil stockpile volumes were determined by IntraSearch, Inc. <br /> utilizing photogrammetric surveying techniques. Topsoil Stockpile 1 is dedicated to <br /> Montrose County for reclaiming portions of either the temporary bypass road or the <br /> landfill. Stockpiled topsoil and the associated underlying undisturbed soil from <br /> Stockpile 5 was moved by scrapers to Stockpile No. 13. Existing topsoil stockpiles 4, 6, <br /> and 7 are also scheduled to be relocated to topsoil stockpile locations 13 or 14 to <br /> • accommodate advancing mining activities in Area 1. The soil volumes for Stockpiles 9, 10, <br /> and 13 were calculated from representative cross sections supplied by the Peabody <br /> 21-10 Revised 08/19/88 <br />
