the first 25 acres of permanent retl amation on final graded spoil will not be completed <br />until 1994. Therefore, sampling from shallow postmine soil pits will not be initiated <br />until the 1997 or 1998 field seasons. <br />Soil Replacement Technique. The soil replacement area for the 1993 field season is shown <br />on Exhibit 93.2, 1993 Soil Balance Map. Soil was replaced on 18.5 acres of final graded <br />slopes in the lower mine block boxcut area. A Clay loam/clay subsoil from Soil Stockpile <br />P1 (PCC, 1993) was spread over most of this reclaimed area. The subsoiled area was then <br />covered with a thin veneer of direct hauled topsoil. Direct hauled soil was also used on <br />those areas not receiving subsoil. <br />Soil Balance. Peabody is submitting the soil balance with the Annual Reclamation Report <br />as required by Permit C-82-057, Tab 21, Pages 5, 32, and 33, and as recommended by <br />Section 2.04.13(2) of Colorado's Regulations for Coal Mining. The soil balance is <br />completed to ensure soil is salvaged, stockpiled, and replaced as recommended and <br />approved in the permit, and, if necessary, to readjust soil salvage and redistribution <br />thickness. the soil information is also used to update the soil volume information <br />Peabody submitted with the 1992 Annual Reclamation Report (PCC, 1993) and confirm the <br />mean soil replacement thickness for the first five-year permit term. <br />Soil Salvage and Storeae. The disturbance area from which soil was salvaged and the soil <br />stoekpile sites as of December 31, 1993 are shown on the 1993 Soil Balance Map, Exhibit <br />93.2. During 1993, soil was imported to stockpile Sites P2, GG, II, and JJ. Soil was <br />exported from Stockpile Site P1, completely depleting its reserve. <br />The following technique was used to prepare the 1993 Soil Balance Map. The soil salvage <br />area end existing soil stockpiles, as of December 31, 1993, were transferred from the <br />Seneca II-Y Pit Progress and Reclamation Digital file to a 1" 400' scale Existing <br />Contours Map dated September 26, 1993. This disturbance area, provided by the Seneca <br />II-Y engineering staff, was Confirmed by overlying the black and white 1" = 400' scale <br />aerial ortho photo dated September 26, 1993 (Exhibit 93.4), overlying the Soil Resource <br />Map, Exhibit 92.2, from the 1992 Annual Reclamation Report, and by on-site field checks <br />on August 13 and October 15, 1993. The remaining soil salvage areas and affected lands <br />boundary for the first five-year permit term are shown on Exhibit 93.2, 1993 Soil Balance <br />Map. The soil salvage areas were determined from the estimated limits of mining and <br />reclamation disturbance shown on the Reclamation Schedule, Exhibit 19-1, dated 10!04!93. <br />Proposed soil stockpile sites shown on Exhibit 93.2 were transferred from the Operations <br />4 <br />
