<br />SOILS DESCRIPTION <br />[Ruks 8 Reps §8.4.9] <br />CONiTROCTION MATCRIAL <br />RraouLAR 112 OftIRATION <br />" WEIMER ONE GRAVEL" <br />January 2001 <br />Corroctions -April 2007 <br /> <br />EXHIBIT 1 <br />Fa[ Np M 2001-002 <br />[a] Soils at the site are named and described by the SCS Soils'Survey map and narrative of the <br />Natural Resources Conservation Service (MRCS, formerly SCS) aS reiterated below. <br />BARX FINE SANDY LOAM (1 TO 3 °~ slopes) Map Symbol 14 <br />The Banc soil is deep end well drained on terraces and mesas. it formed in alluvium from sandstone. <br />Typically, the surface layer is fine sandy loam 5 inches thiGc.', The subsoil is sandy Gay loam 18 <br />inches thiGc. The substratum to a depth of 74 inches is loami Permeability is moderate and the <br />available water capacity is high. Surface runoff is slow and the hazard of water erosion is slight. The <br />effective rooting depth is 60 or more inches. <br />SAPPER - USTIC TORRIORTHENTS (5 to 20 °h slopes) M~p Symbo136 <br />This map unit is 35°~ Clapper soil and 35°~ Ustic Torriorthents s il. <br />The Clapper soil is deep and well drained on terraces, mesas and breaks. It formed in alluvium from <br />igneous roGc. Typically, the surface layer is loam 71 inche$ thiGc. The upper 9 inches of the <br />underlying material is cobbly loam. The lower part to a depth of 60 inches is very cobbly loam. <br />Permeability is moderate to very rapid and the available water c~pasty is moderate. Surface runoff is <br />medium to very rapid and the hazard of water erosion is high to ~Yery high. The effective rooting depth <br />is 60 or more inches. <br />The Ustic Torriorthents soil is shallow to deep end well drained on mesas, terraces, and breaks. It <br />formed in residuum, alluvium, and colluvium from interbedded sandstone and shale. Typically, the <br />surface layer is Gay loam 4 inches thiGc. The underlying material to a depth of 31 inches is Gay <br />loam. Permeability is moderately slow and the available water capacity is moderate. Surface runoff <br />is medium to very rapid and the hazard of water erosion is rioderate to very high. The effective <br />rooting depth is 10 to 60 inches. <br />The sand and gravel resources to be mined at this site are obviou$ly best described as the Clapper, <br />Map Symbo136 soils, only they have been found to have up to 18Q inches of sandy, gravely alluvial <br />deposits (lacking significant humus), beneath 1 to 3 feet of the described surface and sub-surface <br />soils. The sub-surface soil has a high content of powdered calich~e. Topsoil is confined to about a <br />quarter foot of silty clay loam. According to the SCS Soils Mapi Barx soils overly a small portion <br />of the south boundary of the permit area. If truly so it would have to be a very thin eroded remnant <br />veneer, since the reported soil depths above the granular Clapper soils at this site are lacking, and do <br />not significantly vary from the surface soils of the described Clapp~r area <br />Existing vegetation at the site is described by NRCS as "Stony iFoothills" Range Site. Grasses <br />include primarily blue grams, galleta, bottlebrush squirreltail, and three-awn. Forbs and shrubs <br />include big sagebrush, broom snakeweed, ephedra, yucca, senecio,'prickly pear, annual mustard, and <br />astragulas. Pinion pine and Utah juniper trees border just outside ~he southeast periphery, primarily <br />at the crests of the bench slopes and minor draws. Big sage is the predominant plant on undisturbed <br />areas of the site, yet only attains an average height of up to 18 inches, apparently due to the low <br />moisture content and anemic soils. <br />23 <br />
