Banks and Gesso, LLC EXHIBIT I -SOILS INFORMATION Please refer to Exhibit C-2: Pre-Mining Map (Natural Features) and Exhibit I-1: Soils Map for mapped USDA soils. Overview Soils within the proposed permit area consist of the following: • Chipeta-Persayo-Rance complex (CIC) - 2 to10% slopes • Menoken-Chacra clay loam (MkA) - 0 to 2% slopes • Mesa gravelly clay loam, shale substratum (MsA) - 0 to 2% slopes • Mesa gravelly clay loam (MoA) - 0 to 2% slopes • Mesa clay loam (MIA) - 0 to 2% slopes • Rough broken land (Ru) Chipeta-Persayo-Rance complex (CIC) has 2- to 10-percent slopes and is generally found on hills and ridges where Cretaceous shale beds are near the surface. This complex consists of the southwestern corner of the site. Chipeta, Persayo and Rance soils make up equal parts of the complex. The Chipeta series soils are shallow, well- drained and fine-textured. These soils have apale-yellow or light yellowish brown granular surface layer approximately 4-inches thick. The gray subsoil closely resembles the underlying shale but has weak, blocky structure. Typically, the underlying shale starts at a depth of approximately 10 inches and is gray or light yellowish brown in color. Vegetation usually consists of mat saltbush, Gardner saltbush, shadscale saltbush and scattered stands of galleta, Salina wildrye and squirreltail. Chipeta soils are highly susceptible to erosion and require careful management. (USDA, SCS). Menoken-Chacra clay loam (MkA) has 0- to 2-percent slopes and occurs on upland slopes where bedrock is close to the surface. This soil makes up the majority of the southwestern portion of the site. Menoken series soils are moderately deep, well drained or moderately well drained and moderately fine textured. These soils have an approximate 4- to 5-inch thick surface layer that is light brownish gray or grayish brown, friable and granular. The subsoil is typically a light yellowish brown or light olive brown, moderately fine textured soil with weak, prismatic structure or moderate, subangular Haldorson Sand and Gravel Mine 03023 Haldorson and Sons, Inc.
