The upper 12 inches can be salvaged as topsoil, with the underlying 18 inches (from 12 to 30 <br />inches), or depth to bedrock if different than 30 inches, salvaged as subsoil. 0 <br />Map Unit 70: Redcreek-Rentsac Complex (Topsoil 8"/Subsoil 8") <br />Both Redcreek and Rentsac soils are entirely suitable for use in reclamation. The soils are <br />nonsaline and nonsodic, and have suitable texture, organic matter content, coarse fragment <br />content, and water holding capacity. Soil texture is fine sandy loam. Redcreek has an <br />average soil depth of 17 inches and Rentsac channery loam 16 inches to bedrock. The upper <br />8 inches of both soils can be salvaged as topsoil, with the underlying 8 inches, or the depth to <br />bedrock if different from 16 inches, salvaged as subsoil. <br />Map Unit 73: Rentsac channery loam (Topsoil 8"/Subsoil 8") <br />Rentsac soils are entirely suitable for use in reclamation. This soil is nonsaline and nonsodic, <br />and has suitable texture, organic matter content, coarse fragment content, and water holding <br />capacity. Soil texture is fine sandy loam and loam. Rentsac channery loam has an average <br />soil depth of 16 inches to bedrock. The upper 8 inches of can be salvaged as topsoil, with the <br />underlying 8 inches, or the depth to bedrock if different from 16 inches, salvaged as subsoil. <br />Map Unit 75: Rentsac-Piceance Complex (Topsoil 8"/Subsoil 8") <br />Both Rentsac and Piceance soils are entirely suitable for use in reclamation. Both soils are <br />nonsaline and nonsodic, and have suitable texture, organic matter and coarse fragment <br />content. Rentsac soil texture is sandy loam and Piceance texture is fine sandy loam to loam. <br />Because Rentsac is the dominant soil in the map unit, the recommended salvage depth is that <br />for Rentsac, which is limited by a shallow depth to sandstone bedrock. Both soils (Rentsac <br />and Piceance) can be salvaged to the bedrock contact, an average depth of 16 inches for <br />Rentsac, and 30 inches for Piceance. Overall, the upper 8 inches of Map Unit 75 can be <br />salvaged as topsoil, and the underlying 8 inches, or the depth to sandstone bedrock if <br />different than 16 inches, salvaged as subsoil. <br />Map Unit 104: Yamac loam (Topsoil 1211/Subsoil 24") <br />Yamac loam is entirely suitable for use in reclamation. The soil is nonsaline and nonsodic, <br />and has suitable texture, coarse fragment content, and water holding capacity. Organic <br />matter content ranges from 1.8 percent in the surface layer to 1.3 percent in the lowest part of <br />the profile. Soil texture is fine sandy loam. Yamac can be salvaged throughout its profile to <br />bedrock contact, at least 36 inches or more in the study area. The upper 12 inches can be <br />salvaged as topsoil, with the underlying 24 inches (from 12 to 36 inches), or depth to bedrock <br />if encountered, salvaged as subsoil. <br />Map Unit DL: Disturbed Land <br />Several minor areas of Disturbed Land (0.87 acre, 0.6% of total) occur within the study area. <br />These areas consist mainly of berms of stockpiled soil. Most of these areas are less than 0.2 <br />11
