Banks and Gesso, LLC Exhibit I -Soils Information Please refer to Exhibit C-2: Pre-Mining Plan Map (Natural Features) for locations of the soils described below Overview Eight soil types exist within the proposed permit area. These include Kim Loam, Nunn Clay Loam, Aquollos and Aquents Gravelly Substratum, Tassel Fine Sandy Loam, Colby Loam, Otero Sandy Loam, Thedalund Loam, and Weld Loam. Kim Loam is the most prevalent soil type found within the permit area, covering most of the proposed mining area. This is a deep, well drained soil with slopes of 1 to 3 percent. Typically the surface layer is brown and pale brown loam about 12 inches thick. The upper 28 inches of the underlying material is pale brown loam. The lower part to a depth of 60 inches is pale brown fine sandy loam. Permeability is moderate and available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is medium, and the erosion hazard is low. In irrigated areas this soil is suited to all crops commonly grown in the area, including corn, sugar beets, beans, alfalfa, small grain, potatoes, and onions. The potential native vegetation is dominated by blue grama. Wildlife is an important secondary use of this soil, and it also has good potential for urban and recreational development (USDA, SCS). Nunn C{ay Loam is found along the eastern boundary of the proposed mining area. This is a deep, well drained soil with slopes of 0 to 1 percent. Typically the surface layer is grayish brown clay loam about 9 inches thick. The subsoil is light brownish gray clay loam about 14 inches thick. The upper part of the substratum is clay loam. The lower part to a depth of 60 inches is sandy loam. Permeability is moderately slow and available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is slow, and the erosion hazard is low. This soil is used almost entirely for irrigated crops. It is suited to all crops commonly grow in the area, such as those listed above. Trees that are best suited for this soil include Rocky Mountain juniper, eastern redcedar, ponderosa pine, Siberian elm, Russian-olive, and hackberry. Best-suited shrubs are skunkbush sumac, lilac, Siberian peashrub, and American plum. Wildlife is a Raindance Sand and Gravel Mine March 58, 2004 Hilltop Aquatic Investments, LLC tg 04001
