RULE 2 PERMITS <br /> <br />Rule 2 Permits 2.04-48 Revision Date: 11/1/21 <br /> Revision No.: TR-150 <br />rooting depth is 60 inches or more. Surface runoff is medium, and the erosion hazard is medium <br />from wind and water. <br /> <br />Most of this mapping unit is native range and used for grazing. Present and potential productivity <br />of this soil is fair. <br /> <br />33D - Pinelli Loam, 3 to 15 Percent Slopes <br /> <br />This is a deep, well drained soil that occurs at the north edge of the permit area. A portion of the <br />railroad loadout loop was constructed on an area of this soil series. No additional disturbances are <br />anticipated in areas of this soil series; therefore, no detailed chemical or physical data has been <br />collected. The soil developed in local reworked alluvium and is found on upland benches and in <br />swells. The average annual precipitation ranges from 12 to 15 inches, the average annual soil <br />temperature is 42°F to 45°F, and the frost-free season is 75 to 95 days. <br /> <br />Included with this soil in mapping are few small areas that are 40 to 60 inches over soft shale and <br />small areas of Forelle and Evanston sails on north slopes or slightly steeper areas. <br /> <br />Typically the surface layer is a brown loam about 6 inches thick. The subsoil is a yellowish brown <br />heavy clay loam about: 17 inches thick and is calcareous in the lower part. The substratum is; a <br />light yellowish brown clay loam and is calcareous. <br /> <br />Permeability is slow. The available water capacity is high. Effective rooting depth is 60 inches or <br />more. Surface: runoff is moderate, and the erosion hazard is moderate from wind and water. <br /> <br />Most of this mapping unit is cultivated and used for non-irrigated small grains. Some of the area <br />is native range and is used for grazing. Present and potential productivity of this soil is fair. <br /> <br />101 – Torriorthents – Rock Outcrop, Complex <br /> <br />This strongly sloping to very steep complex is on terrace and escarpment faces and valley <br />sideslopes throughout the permit area. Soils are extremely variable in this series. Much of the area <br />has parent material to the surface and is not useful for reclamation purposes. Useable solids are <br />found in isolated pockets throughout this series. Because of the variability of the soils in this series, <br />no detailed chemical or physical data has been collected. The average annual precipitation ranges <br />from 13 to 16 inches, the average annual soil temperature is 42°F to 47°F, and the frost=free season <br />is 75 to 95 days. The Torriorthents make up about 50 percent of this complex and occupy small <br />colluvial fans, toeslopes, and areas of weathered shale. The Rock outcrop part makes up about 40 <br />percent of this complex and occupies vertical ledges, ridgetops and steeper sideslopes. Included <br />with this complex in mapping are a few small- areas of exposed shale ledges, with Rock river and <br />Yamac soils in toeslope positions which make -up the other 10 percent. <br /> <br />The Torriorthents part consists of shallow to moderately deep, coarse to medium textured, stoney <br />and cobbly, well drained soils over sandstone and shale at depths of 10 to 40 inches. These soils <br />have light colored surface and substratum layers, with moderate to rapid permeability, low <br />available water capacity, a moderate wind erosion hazard, and a high water erosion hazard.
