. The soil type on the quarry site is Dalerose soil (Map Symbol DaE) in the Dalerose-Rock <br />outcrop complex. Typically, where soil is available, the surface layer is a gravelly fine sandy <br />loam from 0 to 5 inches deep. The subsurface layer from 5 to 10 inches deep is gravelly sandy <br />loam. From 10 to 60 inches is unweathered bedrock. <br />Included with this soil in mapping are areas of sandstone outcrop, which makes up about 10 <br />percent of the unit. <br />The potential plant community of the Dalerose soil type is mainly pinion and juniper and an <br />understory of sideoats grams, blue grams, and western wheatgrass. The potential production of <br />native understory vegetation in ttormal years is about 1,350 pounds of air-dry vegetation per <br />acre. If the condition of the understory deteriorates, blue grams, cactus, broom snakeweed, and <br />other forbs increase. <br />Woodland products, such as firewood, fence posts, Christmas trees, and pinyon nuts, are <br />produced in azeas of the Dalerose soil. The average site index of pinyon and juniper is about 55. <br />The soil type just below the slope is sandstone outcropping in Cherry Canyon. The transition <br />between the Dalerose soil and fire outcrop complex is rather definite, but a portion of the affected <br />area will likely occur in this soil complex. The Dalerose complex is typically used as rangeland. <br />The Dalerose soil is shallow and well drained. It formed in residuum derived dominantly from <br />sandstone. Slopes range from 3 to 25 percent. The surface layer is typically gravelly sandy loam <br />• about 5 to 10 inches thick. Sandstone is at a depth of about 13 inches. The soil is moderately <br />alkaline. Permeability is very slow in the Dalerose soil. Available water capacity is very low. <br />Effective rooting depth is 4 to 20 inches. Runoff class is high, and the hazard of water erosion is <br />very slight. <br />The potential plant community on the Dalerose soil mainly pinyon and juniper and an understory <br />of sideoats grams, blue grams, and western wheat. The potential production of native understory <br />vegetation on the Dalerose soil is about 1,350 pounds of air-dry vegetation pet acre. If the <br />condition of the understory deteriorates, blue grams, pricklypeaz, broom snakeweed and <br />undesirable forbs increase. <br />The entire area has been grazed by cattle over the years using rotation grazing so the range <br />condition is good considering the drought over the past several years. Erosion has not occurred <br />over the years, and the amount of available soil for reclamation will be good. <br />(b) Permanent Man-made Structures <br />A pipeline and stock tank owned by the applicant occur within 200 feet of the affected azea. <br />~cl Water Resources <br />No streams, springs, lakes, ditches, reservoirs, or aquifers would receive drainage from the <br />affected area. No information is available from publications or monitoring data regarding flow <br />• rates, water table elevations, or water quality conditions. <br />
