• The current total disturbance area which requires topsoil replacement <br />(excludes pre-law spoil piles, pre-law facilities, pre-law shop area, <br />NPDES sites, explosive storage area, all access roads to these areas, <br />and topsoil stockpile locations) is 64.18 acres (Tables 9-3-2 and <br />9-3-3). Suitable spoil, subsoil, and/or excess topsoil will be utilized <br />to reclaim the NPDES sites, pre-law spoil piles, pre-law facilities, <br />pre-law shop area, explosive storage area, and associated access roads <br />to these areas. The suitable spoil, subsoil, and/or excess topsoil <br />materials will be salvaged from areas adjacent to the above areas as <br />part of disturbances associated with final reclamation of these sites <br />(see Topsoil Balance Plan, Exhibit 9-3). <br />Proposed Topsoil Salvage Area <br />All topsoil reserves will be salvaged at Nucla Mine by the end of mining <br />year 1989 (Operations Plan, Exhibit 12-1 and Reclamation Plan, Exhibit <br />13-3). Proposed topsoil salvage areas are outlined on the Topsoil <br />• Balance Plan, Exhibit 9-3. The volume of topsoil to be salvaged, listed <br />in Tables 9-3-2 and 9-3-3, was estimated by soil map unit (Soil Types, <br />Exhibit 9-1 and Soil Types and Topsoil Salvage Depths, Exhibit 9-4). <br />Topsoil salvage depths assigned to each map unit are identical to those <br />used previously for the November 1986 topsoil balance (SMP No. C-008-81, <br />Volume 7, Tab 9, Attachment 9-3). <br />Topsoil Replacement Area <br />Topsoil will be replaced on the areas shown on Exhibit 9-3 (Topsoil <br />Balance Plan) which were all disturbed by mining after the Colorado <br />Rules and Regulations were approved (July 1, 1976). Pre-law spoil <br />piles, pre-law shop area, pre-law facilities, NPDES sites, explosive <br />storage area, and associated access roads, which are still being <br />utilized, are included for suitable spoil, subsoil, and/or excess <br />topsoil replacement. Topsoil will not be replaced within the high water <br />line of irrigation ditches or permanent post-mine impoundments that may <br />be retained upon approval of the Division. <br />9-3-10 Revised 07/18/88 <br />
