Soil Balance. Peabody is submitting the soil balance with [he Annual Reclamation Report
<br />as required by Permit C-82-057, Teb 21, Pages 5, 32 end 33, and as recommended by Section
<br />2.04.13(2) of Colorado's Regulations for Coel Mining. The soil balance is completed to
<br />ensure soil is selvaged, stockpiled, end replaced as recommended and approved in the
<br />permit, and, if necessary, to readjust soil selvage and redistribution thickness. The
<br />soil information is also used to update the soil volume information Peabody submitted
<br />with the 1991 Annual Reclamation Report (PCC, 1992) and confirm the mean soil replacement
<br />thickness for the first five-year permit term.
<br />Soil Selvaue and Storage. The disturbance area from which soil was selvaged end the soil
<br />stockpile sites es of December 31, 1992 are shown on the 1992 Soil Belence Nep, Exhibit
<br />92.2. The following technique was used to prepare the 1992 Soil Balance Map. The soil
<br />salvage area and existing soil stockpiles, as of December 31, 1992, were transferred from
<br />the Seneca 11-Y Pit Progress and Reclamation Map to a 1" = 400' scale Existing Contours
<br />Map dated October 11, 1992. This disturbance area, provided by the Seneca II-N
<br />engineering staff, was confirmed by overlying the black and white 1" = 400' scale aerial
<br />photo dated October 11, 1992 (Exhibit 92.3), overlying the Soil Resource Nap, Exhibit
<br />• 91.2, from the 1991 Annual Reclamation Report, and by on-site field checks on September
<br />18 and October 14, 1992. The remaining soil salvage areas and affected lands boundary
<br />for the first five-year permit term are shown on Exhibit 92.2, 1992 Soil Belence Nap.
<br />The soil selvage areas were determined from the estimated limits of mining and
<br />reclamation disturbance shown on the Reclamation Schedule, Exhibit 19-1, dated 06/21/91.
<br />Proposed soil stockpile sites shown on Exhibit 92.2 were transferred from the Operations
<br />Plan, Exhibit 12-2, dated 03/13/92. Soil map units for the undisturbed areas were
<br />transferred from the baseline soil map, Exhibit 9-1, Soil Types and Topsoil Salvage Nap
<br />(dated 04/19/92).
<br />Soil has been salvaged from 513.1 acres since construction of the tie across haul road
<br />was initiated in 1989. Additionally, 19.5 acres of disturbance are associated with the
<br />mine entrance haul road. The soil has been placed in storage at Stockpile Sites A, C, D,
<br />E, F end G along the tie across haul road, at Stockpile Sites I, J, K, and BB along Haul
<br />Road A, et Sites 1, H, P1, P2, AA, end GG, in the lower mine block, Sites HH end II in
<br />the upper mine block, Sites PP, OD, RR, end SS along Heul Road G, end at Site KK near
<br />Pond 009.
