Baseline Technical Report <br />ARCADIS Report for Soils and Biological <br />Resources, MLE2 Project Area <br />owned by CC &V surrounding the Cresson mine. The legal description of the project <br />area is: <br />• Township 15 South, Range 69 West, Sections 16 to 21 and 29 <br />• Township 15 South, Range 70 West, Sections 24, 25, and 36 <br />The project area ranges in elevation from approximately 9,000 feet (2,743 meters) to <br />10,500 feet (3,200 meters) above mean sea level (amsl). Vegetation communities <br />are relatively diverse consisting of communities such as grasslands, woodlands, and <br />wet meadows. Geology in the District consists of an Oligocene -aged (approximately <br />30 million years ago) diatreme - volcanic, intrusive complex surrounded by <br />Precambrian rocks. The eastern portion of the District is characterized by a flat -lying <br />sequence of volcanoclastic sediments and phonolite flow units. The central portion of <br />the District is dominated by complex flow dome structures with cross - cutting intrusive <br />dikes and sills. The western side of the District contains extensive areas of diatremal <br />volcanoclastic breccias with scattered intrusive and flow dome features (Vardiman et <br />al. 2006). <br />1.2 Survey Methods <br />1.2.1 Phase I — Compile Existing Data <br />ARCADIS performed a detailed compilation of existing resource information available <br />for the MLE2 project area (hereafter referred to as the 'survey area'). The survey <br />area is part of the larger Cresson Project area that encompasses most of the District <br />(Figure 1 -1). Based on the information required by the CMLRB and Teller County for <br />the permit amendment, information on the following resources was compiled: <br />• Soil resources, including plant growth medium; <br />• Vegetation resources; <br />• Wildlife resources; and <br />• Special status species (Threatened, Endangered, Sensitive and Candidate <br />Species [TECS] and Colorado sensitive wildlife and plant species). <br />1.2.1.1 Soil Resources <br />Previous soil surveys were conducted within the Cresson Project area by Nerco <br />Minerals Company in 1984 and by Newport Minerals in 1985. These surveys were <br />conducted in the northern portion of the District. Preliminary soil mapping was <br />CCV Baseline Soils Biology Resource Report (11- 17- 11).doc 2 <br />
