EXHIBIT I — Soils Information <br />Soil Description <br />Soils at the Ashbaugh Expansion site are described on Sheet 41 of 43 in the Soil Survey of Weld County, Colorado — <br />Northern Part published in 1981 by the Soil Conservation Service. <br />Soils at the Ashbaugh Expansion site include Cascajo gravelly sandy loam (unit 20). These soils are excessively <br />drained with moderate wind and water erosion potential. Sandstone and siltstone layers in the Cascajo areas form <br />erosion - resistant ridges; rock outcrops are also common. The Cascajo soils are suitable for rangeland pasture where <br />livestock are managed to prevent overgrazing. <br />The Ashbaugh Expansion site also contains Olney fine sandy loam (units 44 and 45). Olney fine sandy loams are <br />well drained; the surface is typically a brown fine sandy loam overlying a sand clay loam subsoil that is sometimes <br />calcareous. Wind and water erosion potential is moderate. The Olney soils are suitable for non - irrigated rangeland <br />pasture where livestock are managed to prevent overgrazing. Olney soils are also suitable for non - irrigated winter <br />wheat <br />The 1981 soil survey also identifies the areas of Cascajo gravelly sandy loam as a probable good source of roadfill <br />material; but suggests that sand and gravel deposits may not be as valueable die to excessive fines. Weld County's <br />experience at the original Ashbaugh 110c gravel pit is that the materials expected to be found at the adjacent <br />Ashbaugh Expansion site will be quite suitable as a source of gravel road replenishment materials. Top soil at the <br />Ashbaugh Expansion site is sparse and very thin, typically less than 6 inches thick. <br />MADAVE B\Ashbaugh\DRMS permiMmendedApplication & Exhibits.doc <br />4/14/2011 <br />
