Banks and Gesso, LLC secondary use of this soil, and it has fair to poor potential for urban development (USDA, SCS). A small area of Aquollos and Aquints Gravelly Substratum exists at the northern most tip of the permit area. This soil appears on bottomlands and flood plains. Aquolls, which have a dark colored surface layer, make up about 60 percent of the unit, and Aquents, which have a lighter colored surface layer, make up about 35 percent. About 5 percent is Aquepts and Bankard sandy loam. These are deep, poorly drained soils that formed in recent alluvium. Commonly the soils have a mottled, mildly alkaline to moderately alkaline loamy or clayey surface layer and underlying material and are underlain by sand or gravel within 48 inches. In places they have a gleyed layer in the underlying material. Most of the acreage is subject to flooding. These soils are used for rangeland and wildlife habitat. The potential native vegetation is dominated by alkali sacaton, switchgrass, and western wheatgrass. These soils have good potential as a source of sand and gravel (USDA, SCS). Tassel Fine Sandy Loam is found in a small pocket just south of the proposed mining area and west of the proposed haul road. This is a shallow, well drained soil formed in residuum from sandstone, with 5 to 20 percent slopes. Typically the surface layer is light yellowish brown fine sandy loam about 7 inches thick. The underlying material is light yellowish brown very fine sandy loam. Sandstone is at a depth of about 11 inches. Permeability is moderately rapid and available water capacity is low. The effective rooting depth is 10 to 20 inches. Surface runoff is medium, and the erosion hazard is moderate. The potential native vegetation is dominated by sideoats grams, little bluestem, blue grams, threadleaf sedge, sand reedgrass, and needleandthread. Production of vegetation on this treeless soil is low. Rangeland wildlife, such as antelope and scaled quail, can be attracted by managing livestock grazing, installing livestock watering facilities, and reseeding where needed. This soil has poor potential for urban development (USDA, SCS). Colby Loam, Otero Sandy Loam, Thedalund Loam, and Weld Loam are all found only in the southern portion of the permit area, along the proposed haul road. Colby Loam is a deep, well drained soil with 3 to 5 percent slopes. Permeability is moderate, available water capacity is high, and erosion hazard is moderate.
