TAB 9 ATTACHMENT 9-4 SOIL SURVEY - SCRAPER PITS INTRODUCTION Peabody Coal Company will disturb approximately 146 acres of native soils, topsoiled reclamation areas and regraded spoils during the next two years (1987-1988) at Nucla Mine. Mine-related disturbance will occur in five separate areas as shown on Exhibit 12-1 , Operations Plan. Soil surveys at an Order 1-2 intensity were completed in 1979 and 1980 for mining Areas 1 , 4, and 5. The following soil assessment was completed to determine the quality and quantity of topsoil which is available to be salvaged from mining Areas 2 and 3. HISTORICAL. PERSPECTIVE OF PREVIOUS SOIL SURVEYS Peabody Coal Company, in conjunction with the USDA, Soil Conservation Service, Norwood, Colorado, conducted a reconnaissance of Nucla Mine surface soils in 1975. This soils map, originally completed on 1" _ 400' aerial photos dated July 22, 1975, was submitted as part of Surface Mine Permit (SMP) 75-36 (see Exhibit C-5, Soils Map, 7-22-75) . This initial Order 3 soil survey included the entire Nucla Mine Control Area (Portions of Sections 25, 26, 35, and 36 in T47N, R16W and Sections 30 and 31 in T47N, R15W) . An Order 1-2 soil survey was completed by Claude L. Fly and Associates in May, 1979 for the 116-acre miring tract located predominantly in the SW 1/4 of Section 25, T47N, R16W. This soil survey information, submitted as Tab 9 of SMP C-008-81, included all of Mining Area 1 (see Exhibit 12-1, Operations Plan, and Exhibit 9-1, Soil Types) . Two additional Order 1-2 soil surveys were completed for Nucla Mine in 1979 and 1980. First, the East Pit soil survey addition, completed in November, 1979, is located 0.5 miles southeast of the Nucla Mine office in the SW 1/4 NW 1/4 and the NW 1/4 SW 1/4 of Section 31 , T47N, R15 W.
