E Seam Drill Hole for Concrete Delivery Project Plan Minor Revision 333 Page 2 of 9 PROJECT DESCRIPTION The proposed project consists of drilling one (1) cased drill hole to facilitate delivery of concrete to the E Seam from the surface near Shaft No. 3. The proposed hole is in Section 22, of T.13S, R90W, 6m Principal Meridian, Gunnison County, Colorado. The proposed project is within the ciurent permitted coal mining area (Permit Number C-80. 007) and on land surface owned by the Mountain Coal Company L.L.C. The hole will be located on Federal Coal (BLM) Lease COC-044569. The hole will be drilled on the road leading io the methane drainage building near Shaft No. 3. A small hopper to facilitate the delivery of concrete to the E Seam may be constructed and it will be at grade level, installed with a steel door. The steel door will allow vehicles to pass over the top of the hopper and cased drill hole. The attached Map Ado. 53B, at a scale of 1" = 300', depicts the general location of the proposed drill hole, and Sylvester Gulch Facilities. SURFACE TOPOGRAPHY The elevation of the proposed drill hole location is approximately 7020 ft The terrain is comprised of the electric drill hole, Shaft No. 3, and two small methane drainage pump buildings. The principle drainage in this area is an unnamed tributary to Sylvester Gulch GEOLOGY The proposed Project would include drilling along the southeastern edge of the Piceance Basin within the Somerset Coal Field, occurring on the Somerset U.S.G.S. 7 1/2-minute quadrangle map. Initial geological work, in this area was, completed by W. T. Lee (1912), who reported his findings in, "Coal Fields of Grand Mesa and the West Elk Mountains, Colorado" (USGS Bulletin 510). Later in 1948, Ward H. Johnson published a USGS map of the Paonia Coal Field incorporating drill hole data generated through a USGS and U.S. Bureau of Mines drilling program. The following year Johnson further described the geology of the Minnesota Creek area in USBM Technical Paper 721. More nxently, in 1989, C. R Dunrud compiled a coal resources map of the region (USGS Map C-115). In 1998 the Colorado Geological Survey published, "Availability of Coal Resources in Colorado: Somerset Quadrangle, West-Central Colorado (CGS Resormre Series 3~". The general stratigraphy of the area consists of members of the Mesa Verde Formation of the Upper Cretaceous System underlying the Wasatch Formation of Tertiary Age. The Barren Member of the Mesa Verde fommaton crops out lowest in the area with the overlying Ohio Creek member exposed along many of the steeper slopes. Above the
