RULE 2 PERMITS <br /> 2.04.10 Vegetation Information <br /> The objectives of this section are to meet the requirements of the Colorado Regulations of the Colorado <br /> Mined Land Reclamation Board for Rule 2.04.10 et seq. by describing the general vegetation community <br /> types and their distributions within the permit boundary Collom permit expansion area (Map 4). <br /> Vegetation data is provided as cover, species composition, woody plant density, and production to <br /> facilitate development of a revegetation plan and associated performance standards for the Collom mining <br /> area. <br /> General Vegetation Information <br /> General vegetation mapping information was developed based on the following information: <br /> • Colowyo Coal Company Permit C-81-019 - Application for Permit Renewal/Permit Revision - <br /> Mining-Section 2.04.10(Colowyo Coal Co., 1991) <br /> • Digital 1.5 meter-resolution true color remote sensing imagery exposed in the summer of 2002; <br /> and <br /> • Digital 0.5-meter resolution color-infrared remote sensing imagery exposed in September of <br /> 2005. <br /> • Rio Tinto Energy America - Colowyo Coal Company Proposed Collom Mine Project Baseline <br /> Vegetation Survey(Cedar Creek Associates, Inc. 2006). <br /> The vegetation community types described in this section and delineated on Map 4 were originally <br /> reported in the baseline vegetation survey performed in 2006 by Cedar Creek Associates, Inc. This report <br /> is included as Exhibit 10, Item 6. <br /> Detailed Vegetation Information -The area of study for the baseline vegetation survey totaled 13,605 <br /> acres. This area, termed the Vegetation Study Area, includes the potential disturbance footprint of the <br /> Collom permit expansion area. Site specific information collected during the baseline vegetation survey <br /> included: <br /> • General identification of existing vegetation communities and land use types; <br /> • Field sampling of ground cover, production,and woody plant density; <br /> • Determination of species composition. <br /> Introduction - This section describes the general vegetation community types (floral assemblages) and <br /> their distribution within the Collom permit expansion area. Vegetation data are provided in sufficient <br /> detail for use in the formulation of a revegetation plan and development of the associated performance <br /> standards responsive to Rule 4.15.7 for the Collom permit expansion area. <br /> Three referenced delineation areas are considered in the Collom permit expansion area: the Vegetation <br /> Study Area, which encompasses 13,605 acres; a Wildlife Buffer Area, which encompasses 54,000 acres; <br /> and a Disturbance Perimeter, comprised of 3,000 acres. The total acreages of each vegetation type <br /> identified in the Vegetation Study Area and the percent of the total area represented by each type are <br /> presented in Table 2.04.10-33. The vegetation communities delineated are shown on Map 4. This series <br /> of maps depict vegetation communities across the Collom permit expansion area at a 1:500 scale. <br /> Reference areas and transect locations are also shown on the series of maps. <br /> The vegetation inventory effort determined the following parameters in each identified vegetation type: 1) <br /> percent-cover of vegetation, rock, litter, and bare ground; 2) annual production of herbaceous species; 3) <br /> Collom-Rule 2, Page 44 Revision Date: 12/20/19 <br /> Revision No.: TR-135 <br />
