EXHIBIT B SITE DESCRIPTION <br /> 1. Location and General Land Use Information <br /> The site is located along County Road DD and County Road 44 and is composed of and <br /> surrounded by dry rangeland. The parcel is currently leased for wind energy operations by the <br /> Colorado State Land Board. <br /> 2. Site Geology <br /> Site geology consists of 0-3 inches of topsoil. Mining will occur to a depth of approximately 15 <br /> feet below the present surface. There are no hazardous or acid forming materials expected to be <br /> encountered during excavation. See the enclosed Natural Resources Conservation Service <br /> (MRCS) soil report for more details on surface composition. <br /> 3. Surface Hydrology <br /> Prior to mining, the permit area has a very shallow slope. Pre-mining topography is shown on the <br /> Existing Conditions Map. All the runoff on the undisturbed site runs to the east. Stormwater will <br /> be kept from leaving the site by utilizing topsoil and overburden stockpiles which will surround <br /> the site following the perimeter. The stockpiles will be first developed on the western edge of the <br /> site and will encircle the full area over the mine's life. This perimeter topsoil berm is shown on the <br /> Mining Map. Stormwater that occurs on site will remain on site by perimeter berms; however, the <br /> porous surface of the site will allow for all stormwater to infiltrate the site and pit floor within 72 <br /> hours. <br /> Based on data from the Division of Water Resources Well Permit Search map, groundwater is <br /> not anticipated to be encountered during any phase of mining. A well on the site is at a depth of <br /> 78 feet. Mining is not anticipated deeper than 20 feet. If groundwater is encountered, excavation <br /> will be halted, and the area will be backfilled with at least two feet of site excavated material. No <br /> mining will occur beyond the depth where groundwater is encountered, if required. <br />
