EXHIBIT I <br /> Soils Information <br /> At the end of this exhibit are printouts from the NRCS Web Soil Survey website that describe the location and typical <br /> characteristics of the soils present on the site, <br /> According to the Web Soil Survey(United States Department of Agriculture, NRCS, 2004)of the proposed permit <br /> area,there are eight USDA soil types within the proposed project site: <br /> 1. Ellicott-Glenberg complex,0 to 3 percent slopes, occasionally flooded <br /> 2.1-oamy alluvial land,gravelly substratum <br /> 3.Loamy alluvial land, moderately wet <br /> 4.Nunn clay loam, 1 to 3 percent slopes <br /> 5.Terrace escarpments <br /> 6.Ulm loam,5 to 9 percent slopes <br /> 7.Water <br /> 8,Wet alluvial land <br /> In addition,Aggregate Industries obtained test borings for the property. Test borings indicate a layer of topsoil and <br /> overburden ranging from 1 to 11 feet in depth with a typical depth of 5 feet. In the western part of the site,the topsoil <br /> has been tilled until recently and likely contains a significant percent of organics. The overburden is underlain by an <br /> aggregate layer with a thickness ranging from 0 to 46 feet with a typical thickness of 25 feet. In some parts of the <br /> site,the aggregate layer contains a 2 to 9-foot-thick mud lenses. The total depth to bedrock from the surface grade <br /> ranges from 5 feet in the west to 50 feet in an apparent paleochannel in the eastern part of the site. The typical <br /> depth to bedrock is approximately 27 feet over most of the mine area. The aggregate layer overlies sedimentary <br /> bedrock of the Denver Basin. <br /> A complete summary of the test logs was submitted with the initial DRMS application for this site, The information is <br /> on record and the Division and is attached here in for reference: <br /> Aggregate Industries Tucson South Resource <br /> Permit#M-2004-044112 Permit Amendment <br /> Page 1-1 <br />
