The Bowie No. 2 Mine permit azea 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 1'iceance Creek structural and sedimentary basin. The azea is bounded by I.arimide structural and physiographic features on the following sides: West Ells and Ells Mountains on the east; the Gunnison Uplift on the south; the Uncompahgre Uplift on the west-southwest; and the Grand Mesa- 1'iceance Basin on the north. The geologic structure of the permit area exhibits an attitude of N66°W, with a 3- to 5-degree dip to the northeast. There is one identified fault located in the southwest corner of the permit area. The fault trends approximately N55°W and it dips 70 to 80 degrees to the northeast. The throw of the fault ranges from 7 to 30 feet, with the downside located on the south side of the fault. The coal in the area is situated within Mesaverde formation which contains interbedded sandstones, mudstones, shales, siltones and coal beds. The Mesaverde formation lies upon the Rollins Sandstone Member of the Iles formation and below the Wasatch formation. The coal bearing member of the Mesaverde formation locally contains up to nine (9) coal seams. These seams are located within a stratigraphic interval of approximately 500 to 600 feet above the Rollins Sandstone. These coal seams are, in ascending order, the A-Seam, the B-1 Seam, the B-2 Seam, the C-Seam, the D-1 Seam, the D-2 Seam, the E-1 Seam, the E-2 Seam and the F-Seam. The B-2 and D-2 Seams aze mineable within the permit area, and mining will occur within the D-2 Seam during the first five-year permit term. The D-2 Seam overlies the Rollins Sandstone by 350 to 450 feet, and it ranges in thickness from about 8 to 16 feet. Hydrology - Detailed information regarding the surface and groundwater hydrology in and adjacent to the Bowie No. 2 Mine permit area is provided within Sections 2.04.5 and 2.04.7 of the permit application document. A brief summary is provided below, and the summary is derived from the information presented in permit application Sections 2.04.5 and 2.04.7. The permit and adjacent areas aze generally bounded by three (3) perennial streams. These streams aze Terror Creek, Hubbard Creek and the North Fork of the Gunnison River, and the streams are located west, east and south of the permit area, respectively. Tributary to the perennial streams are the following intermittent and ephemeral streams: Freeman Gulch, Stephans Draw, A-Gulch, 5
