3.2.2 General, Disturbed and Affected Area <br />The Mine is located approximately 28 miles southwest of Craig, Colorado, west of State <br />Highway 13. The great majority of the permit area and current operations (including the mine <br />pits, the administrative building, shops, warehouses, and rail loadout facility) are located in <br />Moffat County. A small percentage of the area is in Rio Blanco County. <br />All new disturbance associated with PR -04, 155.1 acres, is in Moffat County. <br />3.2.3 Coal Resources to be Mined <br />In the Collom permit expansion area, Colowyo will mine coal in the Danforth Hills coal field. <br />Coal seams Y, X, A, B, C, E, F, and G are proposed to be mined in the Collom Pit. Seam <br />thicknesses vary in the Collom permit expansion area from 5 to 11 feet. The general stratigraphy <br />within the Collom permit expansion area is depicted in Exhibit 6, Item 7, Figure 3. 1, and Exhibit <br />6, Item 8. <br />3.2.4 Topography <br />The Collom permit expansion area is located west of the West Pit, and expands the current <br />western permit boundary to just west of Collom Gulch. It is bounded on the west by Morgan <br />Creek, and includes Collom Gulch, Little Collom Gulch and the West Fork of Jubb Creek. <br />Elevations in the Collom permit expansion area range from just below approximately 6,400 feet <br />mean sea level to approximately 8,570 feet. Slopes in the Collom permit expansion area range <br />from moderately steep to steep drainages (> 35 percent) to benches between the drainages (from <br />1 percent to 5 percent). The predominant land uses in the Collom permit expansion area are <br />rangeland and fish and wildlife habitat, with smaller acreage characterized as pastureland. <br />3.2.5 Geology <br />Geologic information is found in Sections 2.04.6, Maps 7 through 9A, and Exhibit 6 of the PAP. <br />The permit area and Collom permit expansion area are south of the axis of the Axial Basin <br />Anticline, a large northwest -trending fold found in the southern Uinta region of the Piceance <br />Basin. The southern limb of the Axial Basin anticline is shared with the Collom syncline. The <br />southern limb of the Axial Basin anticline is shared with the Collom syncline. The anticline and <br />syncline consist of thousands of feet of marine deposited sediments of Cretaceous age. <br />PR -04, Colowyo Coal Mine C1981-019 18 August 2016 <br />
