This <br />' information normally need no[ be repeated here per Rule 1.10.4 (1) except <br /> that: additional information has since been obtained necessitating some <br />' minor corrections in descri <br />ti <br />Additi <br />a <br />v <br />ll <br />b <br />f thi <br />d <br />i <br /> p <br />ons. <br />ona <br />y, <br />ec <br />use o <br />s <br />mpro <br />e <br />' accuracy, it was discovered [hat two of the mapping units previously <br /> desc:cibed do not occur in the permit area. The revised information is thus <br />~ ' provided below. <br /> Descriptions and delineation of the soil mapping units were completed <br />' by the USDA Soil Conservation Service (SCS). Figure I is a soils map <br />~ ' illustrating the delineation of the soil mapping units relative to the <br /> affected area of this application. The soil types occurring in [he <br />' affected area are the Lincoln sand (Lv) and the Glendive-Havre complex <br /> (GnA). The majority of the affected area consists of the Lincoln sand <br />I' (Lv). <br /> Descriptions of these soil mapping units are given below. <br />' <br /> (Lv) Lincoln sand (0 to 1 percent slopes). <br /> Soils of the Lincoln series are excessively drained, coarse textured <br /> soils of the Alluvial great soil group. They occur on nearly level bottom <br /> lands and low terraces of the Arkansas River and its tributaries. These <br />' soils are calcareous and have little profile development. They are subject <br /> to frequent flooding and deposition of soil material. The texture of the <br /> surface layer ranges from loam to loamy sand oc sand. In most places the <br />' surface layer is brown or grayish-brown loamy sand or light sandy loam <br /> about 5 to 10 inches thick. Normally the subsoil and substratum are loamy <br /> sand or loamy fine sand that in many places is stratified with lenses of <br /> sandy loam and sand. Depth to the underlying sand and gravel ranges from <br />' about 16 to more than 60 inches. Permeability is very rapid and the <br /> available water holding capacity is very low. <br />' In many places the surface layer of the Lincoln sand (Lv) is loamy <br /> sand or sandy loam, and in many small depressions or old stream channels it <br /> is e•~en finer textured. Included in areas mapped as this soil are many <br />' areas that have gravelly sand throughout the profile. Other included areas <br />1 <br />
