3. "As shown on the E-Seam thickness map (Map 18), the mineable E-Seam reserve is bounded on the northwest, east, and south by the thinning of the uppermost, EO coal bench to 8 foot in thickness. To the southwest, the E-Seam reserve is restricted by outcrop. To the north, the E- Seam is merged with the underlying D-Seam and has been mined by the Oliver No. 2 Mine operation." [Permit page 2.04-32 (revised June 1995; revised January 1998)] 4. "Along Highway 133 east of the West Elk Mine near Box Canyon, two large dormant landslides were reactivated in 1980 by highway excavation. One lies east of Box Canyon and one occurs to the west between Box Canyon and the portal of the Oliver No. 2 Mine". [Permit page 2.04-41 (revised June 1995; revised January 1998)] 5. "The CDOT maps indicate the road embankment was constructed directly over the Oliver No. 2 Mine portal. The fan portal is immediately north of the embankment and a third portal is immediately south of the embankment" [Permit page 2.04-42 (revised June 1995; revised Jan 1998)]. 6. "The mine closure report for the Oliver No. 2 mine describes the occurrence of considerable methane within the E/D-Seam." [Permit page 2.04-48 (revised June 1995; revised January 1998)] "The Oliver No. 2 mine was an E/D-Seam coal mine operated east of Sylvester Gulch during the 1940s and early 1950s (See Map 5 of the permit). Based on information contained in the Oliver No. 2 Mine closure report dated October 1953, water- and methane-filled fractures within the mine's E/DO-Seam were encountered in the floor of the Oliver No. 2 Mine. (Both water and methane were reportedly under high pressure). The fractures (with a reported N77°E trend) were encountered during pillaz development before any fractures produced by floor-heave would likely have occurred." [Exhibit 60, "Subsidence Evaluation for the Apache Rocks and the Box Canyon Mining Areas -May 1996; Revised February 1998", page 18; repeated on Permit page 2.05-124 (March 2005)] "All of the Oliver No. 2 Mine workings aze outside the angle of draw of planned B-Seam mining, with the exception of the first Box Canyon panel." [Exhibit 60, "Subsidence Evaluation for the Apache Rocks and the Box Canyon Mining Areas -May 1996; Revised February 1998", page 18; repeated on Permit page 2.05-125 (March 2005)] 9. "Because -azge quantities of water and methane were encountered while mining the E/DO- Seam in the Oliver No. 2 Mine, other sources may also be present in the Box Canyon mining area. In the report on the closure of the Oliver No. 2 Mine, lazge volumes of water and methane began to flow from fractures in the floor of the southernmost (top) entry of 6`h East. The mine was evacuated and closed because the water and methane flowed in quantities too costly to control. This area where the large outpouring of water and methane occurred is located about 300 feet south of entries of the South Mains that were not driven further, apparently because of roof control problems".
