RULE 2 PERMITS <br />Most of this mapping unit is native range and used for grazing. Present and potential productivity of this <br />soil is good. <br />19E Campspass Fine Sandy Loam, 12 to 25 Percent Slopes <br />This is a deep, well drained soil that occurs throughout the permit area. Only the surface soil of this series <br />is acceptable for reclamation purposes. The usefulness of the subsurface soil is limited by its high clay <br />content. It developed in interbedded sandstone and shale and is on upland valley sideslopes. The average <br />annual precipitation ranges from 15 to 18 inches, the average annual soil temperature is 42°F to 47°F, and <br />the frost-free season is 75 to 95 days. <br />Typically the surface layer is a grayish brown fine sandy loam about 2 inches thick. The subsurface layer <br />is light brownish gray fine sandy loam about 2 inches thick. The subsoil is light brownish gray heavy clay <br />loam about 27 inches thick. The subsoil is calcareous in the lower 7 inches. The substratum is gray heavy <br />clay loam about 30 inches thick. It is calcareous. The surface layer may be absent. <br />Permeability is slow. The availability water capacity is high. Effective rooting depth is 60 inches or more. <br />Surface runoff is rapid, and the erosion hazard is high from wind and water. <br />Most of this mapping unit is native range and used for grazing. Present and potential productivity of this <br />soil is fair. <br />28D - Forelle Loam. 3 to 12 Percent Slopes <br />This is a deep, well drained soil that occurs in very limited areas at the north end of the permit area. A <br />small area (less than 5 acres) of this series was disturbed by the access road. No additional activities are <br />planned on areas with this soil series, therefore detailed chemical and physical data has not been collected <br />for this soil type. The soil developed in mixed aeolian materials and is found on gently to moderately <br />sloping terraces. The average annual precipitation ranges from 12 to 15 inches, -the average annual soil <br />temperature is 42°F to 47°F, and the frost-free season is 75 to 95 days. <br />Included with this soil in mapping are a few small areas of Yamac and Pinelli soils. <br />Typically the surface layer is a grayish brown loam about 5 inches thick. The subsoil is a light brownish <br />gray clay loam about 16 inches thick. The substratum is a light grayish brown loam to a depth of about 60 <br />inches. <br />Permeability is slow. The available water capacity is high. Effective rooting depth is 60 inches or <br />more. Surface runoff is medium, and the erosion hazard is moderate from wind and water. <br />Most of this mapping unit is cultivated and used for non-irrigated small grains. Present and potential <br />productivity of this soil is fair. <br />32D-Yamac Loam, 5 to 15 Percent Slopes <br />This is a deep, well drained soil that occurs at the northern edge of the permit area. A portion of the unit <br />train loadout facility was constructed on an area of this soil series. No additional disturbances are <br />anticipated on areas with this soil series, therefore detailed data on chemical and physical characteristics <br />are not presented. The soil developed in weathered sandstone, siltstone and windlain materials, and is <br />found on upland ridges and benches. The average annual precipitation ranges from 12 to 15 inches, the <br />average annual soil temperature is 42° to 47°F, and the frost-free season is 75 to 95 days. <br />Rule 2 Permits 2.04.9-4 Revision Date: 6/23/08 <br />Revision No.: MR-91
