Land Use and Cultural and Historic Resource Information - Detailed information regarding land uses and cultural and historic resources within the Bowie No. 2 Mine permit area is provided in Sections 2.04.3 and 2.04.4 of the permit application document. Abrief summary is provided below, and this summary is derived from the information presented within Sections 2.04.3 and 2.04.4 of the permit application document. The Bowie No. 2 Mine permit and adjacent area includes a mix of land uses. The lower elevation areas are used for pasture,orchards, residential and industrial uses. Approval of Permit Revision No. 6 added hayland to the list of permit area land uses. Agricultural uses are served by irrigation water. The higher elevations within and adjacent to the permit area support some rangeland use, and the areas offer abundant wildlife habitat. The lands also support various recreational uses. Historic and current mining operations also exist in the general area. The Bowie No. 1 Mine is located west of the Bowie No. 2 Mine permit area. The Terror Creek Loadout is located to the south of the Bowie No. 2 Mine permit area. The reclaimed new Blue Ribbon Mine is also located nearby along Hubbard Creek, as are outlying facilities associated with the Sanborn Creek Mine. Historic coal mines located within and adjacentto the Bowie No. 2permitboundary include the King Mine, the Gelwick Mine, the old Blue Ribbon Mine and the Farmers' Mine. The old townsite of Bowie is located within the Bowie No. 2 permit area. There are no known historical sites that are eligible to the National Register in the areas to be disturbed under Permit Revision No. 6. Three historic sites, not associated with important persons or events in history and not eligible to the National Register, were determined by the CHS to not have much integrity due to deterioration and alteration. As requested by the Colorado Historical Society, BRL has committed to stop construction and evaluate the situation appropriately, in consultation with the Colorado Historical Society, if previously unknown cultural resources should be discovered. Geology - Detailed information regarding the geology in and adjacent to the Bowie No. 2 Mine permit area is provided in Sections 2.04.5 and 2.04.6 of the permit application document. Abrief summary is provided below, and this summary is derived from the information presented within Sections 2.04.5 and 2.04.6 of the permit application. The Bowie No. 2 Mine permit area is located in the North Fork Valley of the Gunnison River, near the western margin of the Colorado portion of the Central Rocky Mountains. The elevation of the permit area ranges from about 6,000 feet above sea level to over 8,000 feet above sea level. The general area is situated along the southern flank of the Piceance Creek structural and sedimentary basin. The area is bounded by Larimide structural and physiographic features on the following sides: West Elk and Elk Mountains on the east; the Gunnison Uplift on the south; the Uncompahgre Uplift on the west-southwest; and the Grand Mesa-Piceance Basin on the north. The geologic structure of the eastern permit area exhibits an attitude of N70°W and dips 3 to 5 degrees to the northeast. The western permit area exhibits an attitude of N88°W to N76°W and dips 4 to 7 degrees to the northeast. The structural dip direction changes near Terror Creek due to faulting. There are numerous faults located within and adjacent to the permit area. The faults in the central portion of the permit area are high angle normal faults. These faults trend N40°W and dip 70 to 80 degrees to the northeast. The fauhs have a strike -slip component. The throw of the faults ranges from 7 to 30 feet. The coal in the area is situated within Mesaverde formation which contains interbedded sandstones, mudstones, shales, siltstones and coal beds. The Mesaverde formation lies upon the Rollins Sandstone 14
