' Map included with the Third Annual Topsoil and Spoil Monitoring Report for Seneca II Mine. <br /> ' All topsoil replaced during 1989 was direct hauled. <br /> Topsoil Redistribution Plan <br /> A topsoil redistribution plan has been prepared for the life-of-mine operation at Seneca <br /> ' II Mine to comply with Rule 2.05(4)(d), show redistribution areas for individual topsoil <br /> stockpiles including X and T, and satisfy the soil related items presented in the Seneca <br /> II mid-term review document for Permit C-80-005. The topsoil redistribution plan for the <br /> 1989 field season is presented as Exhibit 3. The existing and projected topsoil <br /> ' disturbance areas presented on Exhibit 3 coincide with those shown on Exhibit 2, Topsoil <br /> Balance Plan - 1989 Field Season. Topsoil redistribution areas were determined from the <br /> most recent Operation Plan, Exhibit 12-1 (dated October 26, 1989), and Reclamation Plan, <br /> ' Exhibit 13-2 (dated February 21, 1990), schedules. <br /> Redistribution areas and corresponding topsoil volumes are listed in Table 8. The topsoil <br /> source, including stockpiles (17 total) and direct haul from either the Wadge or Wolf <br /> Creek mining areas, are also included for each redistribution area. The topsoil source <br /> for each redistribution area is noted on Exhibit 3. <br /> ' Quality Control <br /> ' Quality control is an important part of the topsoil and spoil monitoring program at Seneca <br /> II Mine. Two aspects of this quality control program are to evaluate the topsoil salvage <br /> operation and to have the analytical laboratory complete duplicate analyses on five to ten <br /> percent of the total samples. <br /> Laboratory Analysis. Inter-Mountain Laboratory completed duplicate analyses on six <br /> ' samples. Two of the samples were split in the field and submitted as blind duplicates to <br /> IML. The duplicate analyses are listed in Table 4. Overall, duplicate analyses were <br /> extremely similar to the original data and often varied less than rive to ten percent for <br /> all parameters. Coefficient of determination values for pH, EC, ABP, and Mn were 0.99, <br /> 0.87, 1.00, and 1.00, respectively. The topsoil and spoil suitability evaluations and <br /> interpretations did not change based upon the duplicate analyses data. <br /> Topsoil Salvage. A topsoil balance quality control study was completed for the 1989 field <br /> season to compare the projected topsoil salvage quantity determined from the baseline soil <br /> I PEABODY COAL COMPANY <br /> 9 Western Division <br />
