2.04.9 Soil Resource Information <br />• <br />As mentioned throughout this application, the permit and adjacent area <br />has been extensively disturbed by previous activities. During some of <br />these past activities, the virgin soils of the area have undoubtedly <br />been disrupted and perhaps destroyed. Nonetheless, Mt. Harris has <br />contacted the USDA Soil Conservation Service ("SCS") for soil types and <br />descriptions in the permit, adjacent, and general area. <br />Soils found in the area are delineated on the Sails Map (Map 3). Soil <br />work has been completed by the SCS on the permit, adjacent, and general <br />area. <br />The only soil found in the permit area is Apmay-Nesda Variant Complex <br />which occurs on 0 to 3 percent slopes. This particular soil unit is <br />found on stream terraces. <br />• Information obtained from the Soil Conservation Service (SCS) identifies <br />this soil unit as 60% Gas Creek soil and 30% unnamed soil. Also in this <br />unit are about 10% unnamed soil and Aquents-Aquolls complex. <br />The Apmay soil is deep and somewhat poorly drained. It formed in <br />gravelly mixed alluvium. The upper 19 inches of the surface layer are <br />dark grayish brown sandy clay loam. The lower 5 inches of the surface <br />layer are dark grayish brown gravelly sandy loam. The substratum to a <br />depth of 60 inches is light yellowish brown extremely gravelly sand. <br />Permeability of the Apmay soil is moderate. Available water capacity is <br />low. Runoff is very slow, and the hazard of water erosion is slight. <br />The Nesda Variant soil is deep and somewhat poorly drained. It formed <br />in gravelly mixed alluvium. Typically, the upper 5 inches of the <br />surface layer are dark grayish brown very gravelly sandy loam. The next <br />10 inches of the surface layer are dar4: grayish brown gravelly sandy <br />• loam. The lower 6 inches of the surface layer are brown extremely <br />2.04.9-1 <br />
