BTUEC is currently pumping water out of the No. 5 Mine workings, in the event that mining operations will resume. The water is pumped through ponds 5-P5, 5-P6 and 5-P7 (in sequence) and discharged into the Williams Fork River. The discharge point (at 5-P7) is an NPDES discharge point (NPDES 003) and is monitored weekly, semi-monthly, monthly and quarterly for various NPDES parameters. BTUEC did complete some reclamation and demolition in the spring of 2008. The buildings that were demolished include the compressor house, old shop, Oaky Plaza well shop, No. 9 warehouse, B&S shop, bathhouse, Guard shack and fence, lab trailer and sample building, well house by B&S shop, little shed south of Wise Hill portal, old carpenter shop and contractor staging area, old (AML) mine site, rock dust tank #1 and rock dust tank #2. All of these areas were regarded, the topsoil was replaced, where possible, and the areas were seeded with the rangeland seed mix. The demolition debris was buried in the solid waste disposal area on the east side of Colorado highway 13, by the waste disposal area. The solid waste disposal area was permitted through Technical Revision 34. Permit Area, Disturbed Area, and Production Volumes The permit area covers approximately 6,363 acres. The disturbed area totals 422.0 acres. The surface disturbance includes three existing portal areas; the No. 5 Portals, the No. 5A Portals, and the No. 9 Portals. Access to the No. 6 Mine is from within the existing areas of the No. 5 Mine. This access is through the 5A Portals. No new surface disturbance was caused by driving ramps from the F seam (No. 5 Mine) down to the E seam (No. 6 Mine). When mining resumes, the projected maximum annual tonnage for the Eagle No. 6 Mine is 4.0 million tons Associated Facilities. These include: mine dewatering ponds, sediment control ponds, haul roads, conveyors, breakers, silo, loadout, rail spur, sampler, scale, and mine buildings. Mining Method Three of the Eagle Mines are underground mines, while the Williams Fork Strip Pit No. 2 was a surface mine. The No. 5 Mine extracted coal from the F seam, and the No. 6 Mine extracts coal from the E seam. The permitee partially extracted coal from the P seam in the No. 9 Mine as approved in a permit revision application (see findings document of April 9, 1984). Room-and-pillar and longwall mining methods have been used in the mines to extract the coal resource. In the No. 5 mine, conventional underground techniques were used for developing mains, submains and longwall panel entries. Room-and-pillar extraction techniques were used initially. More recent mining utilized longwall mining methods. The No. 6 Mine also used conventional mining techniques for development mining and used longwall methods within production panels. The Williams Fork Strip Pit No. 2 was mined and portions of the Williams Fork strip pit area was reclaimed prior to 1978 (Exhibit 28). Portions of the Williams Fork Strip Pit area were redisturbed after 1978 with the intention of constructing additional portals to the No. 9 Mine. Mining ceased in the No. 9 mine in 1985 and no portals were driven from the Williams Fork Strip Pit No. 2 to the No. 9 Mine. The Williams Fork Strip Pit No. 2 highwall was reclaimed after cessation of mining of the No. 9 Mine. The Division continues to hold reclamation bond for those portions of the Williams Fork Strip Pit No. 2 that were redisturbed after May 3, 1978. Transportation of Coal and Waste. When the mine was active, a conveyor carried coal from the No. 6 Mine to a silo where it was loaded onto a unit train. Waste rock was conveyed from the Eagle Mine Complex 10 Permit Renewal 05 C-1981-044 May 22, 2009
