RULE 2 PERMITS <br /> <br />Rule 2 Permits 2.04-44 Revision Date: 11/1/21 <br /> Revision No.: TR-150 <br /> 32 Yamac Loam <br /> 33 Pinelli Loam <br /> 101 Torriorthents – Rock Outcrop Complex <br /> 104 Borolls – Rock Outcrop Complex <br /> 105 Kemmerer – Moyerson – Silty Clay Loams <br /> X-110 Kemmerer – Yamac Complex <br /> RL Rock Ledge <br /> <br />The soil series are delineated on the Soils - North Map (Map 5) and the Soils - South Map (Map <br />6). <br /> <br />Soil profile descriptions and Range Site Descriptions from information provided by Soil <br />Conservation Service are found in Exhibit 9, Soils Information. <br />The descriptions of the soils series are as follows: <br /> <br />03B – Havre Fine Sandy Loam, 0 to 5 Percent Slopes <br /> <br />This is a deep, well drained soil that occurs along drainage ways in and adjacent to the permit area. <br />A very small area (about: 1 acre) of this series was disturbed by the access road, no additional <br />activity is anticipated on areas of this series. Therefore, detailed chemical and physical data has <br />not been collected for this series. It developed in stratified alluvium from sandstone and shale and <br />is on flood plains and terraces. The average annual precipitation ranges from 12 to 16 inches, the <br />average annual soil temperature is 42° to 47°F, and the frost-free season is 75 to 95 days. <br /> <br />Included with this soil in mapping are small areas of Homelake, Glendive, and Havre saline phase <br />soils. <br /> <br />Typically the surface layer is a dark gray fine sandy loam about 3 inches thick. The substratum is <br />calcareous and stratified with colors of gray, light brownish gray, and pale brown. Textures are <br />fine sandy loam, loam, sandy clay loam, silt loam, and silty clay loam. Mottling may occur below <br />40 inches. <br /> <br />Permeability is moderate. The available water capacity is high. Effective rooting depth of 60 inches <br />or more. Surface runoff is slow, and the erosion hazard is moderate from wind and low from <br />water. <br /> <br />Most of this mapping unit is used for non-irrigated and irrigated hay and pasture. Present and <br />potential productivity of the soil is good. <br /> <br />14E – Burnette Loam, 12 to 25 Percent Slopes <br /> <br />This is a deep, well drained soil that occurs throughout the area to be mined. This soil provides the <br />best and most abundant source of plant growth medium of the soils in the permit area. The depth <br />of useable soil is extremely variable, depending upon slope and location, and in the bottom of the <br />Streeter drainage the A horizon has been found to be as thick as twenty (20) feet. The soil <br />developed in mixed sandstone and shale and is found on upland valley sideslopes and benches.
