Section 816.22 (c) Continued. Revised 12/12/80 It is therefore concluded that the Cryorthent area within Pit 112 is unacceptable as material to be salvaged for topsoil. The substitute material to be used here is topsoil and subsoil sal- vaged from the adjacent Coalmont (X73) soil area in Pit 112. From Table 59, Soil Redistribution Plan, it can be seen that the topsoil replacement depth for Pit 112 is 0.43 feet, and the subsoil re- placement depth is 1.34 feet, for a combined soil replacement depth of 1.77 feet under this configuration. Because of the significant- ly superior quality of the soil in the Coalmont (X73) area and the sufficient quantity of it available for retopsoiling the entire Pit 112 area, the Cryorthent area will not be salvaged. In the Pit 113 area, a similar situation exists in several respects. The Cryorthent area in P1t 113 has no horizon development, no struc- ture development, an extremely gravelly surface, and high calcium carbonate equivalent content. Other soi15 within Pit 113 include Fluetsch (X15), Gelkie (X30), Morset (45), Coalmont (X73), and disturbed soil areas. All of these other areas are without the restrictive features of the Cryorthent soil area. Data exhibiting these differences are found in Table 42, Soii Chemical and Physical Properties Lab Analysis Kerr North Area, in Exhibit 26, Soil Profile Descriptions, Exhibit 27, Soil Mapping Unit Descriptions, and in Section 779.21. Also in the category of thin topsoil is the Spicerton (X31) soil type. The range in depth of the A horizon is 1 to 4 inches (See: Exhibit 26, Soil Profile Descriptions), with the depth generally 1 to 2 inches. Six inches of the soil material in this area will be salvaged. Most of the disturbance for this soil type is for the purpose of constructing haul roads between Pit 111 and Pit 112 and between Pit 112 and Pit 113. The remainder of this soil type to be disturbed is adjacent to the stream buffer zone north of Pit 112 in 816-12 aaaa
