i r §2.04 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES --MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES. Included with these soils in mapping are areas of Mesa soils and Badland. Small slips and slides occur in places. Included areas make up 20 percent of the map unit. The Utaline soil is deep and well drained. It formed in old landslide deposits and glacial outwash derived from material of mixed origin. Typically the surface layer of the Utaline soil is pink stony loam about 4 inches thick. The upper part of the underlying material is pink very cobbly loam about 14 inches thick. The lower part, to a depth of 60 inches, is pinkish white to pinkish gray extremely cobbly loam. Torriorthents generally are highly variable. Development of a soil profile is absent or slight in most places. In some areas shale bedrock is near the surface. Available water capacity of Torriorthents is limited but is higher where the soil is deeper. Surtace runoff is rapid, and the hazard of erosion is high. A vegetative cover is needed to control runoff and erosion. The native vegetation in areas of Torriorthents consists mainly of mat saltbush, shadscale, fourwing saltbush, rabbitbrush, galleta grass, Indian ricegrass, and squirreltail. Permeability and available water capacity are moderate. Effective rooting depth is 60 inches. Surface runoff is moderate to rapid. The hazard of erosion from wind is slight and from water is moderate to high. Surtace stoniness helps to control erosion. The native vegetation on the Utaline soil consists mainly of galleta, Indian ricegrass, squirreltail, shadscale, and tall rabbitbrush. Some success can be expected from broadcasting of seed. Grasses that meet the seasonal requirements of livestock should be selected. Seeded areas should be fenced. Because of instability of the soils and steep slopes, these soils are unsuited to farming. Seedbed preparation and drilling of seed for pasture plantings are not practical. A limited degree of success can be expected by broadcasting of seed late in summer or early in fall. Western wheatgrass, crested wheatgrass, and alkali sacaton are adapted species. Good pasture management must be practiced to protect the soils from erosion. These soils provide habitat for pronghorn antelope, desert cottontail, and mourning dove. Where water is available, water developments and food plots can be used to improve wildlife habitat. Founving saltbush is an important wildlife plant that grows on these soils. If these soils are used for urban development, the main limitations are stoniness, slope, and corrosivity. The limitations can be overcome by the use of proper design and construction methods. This complex is in capability subclass Vlle, nonirrigated. TR-20 2.04 - 26 3/01
