Cultural and Historic Resources. There are 31 known cultural and historic resource sites within <br />the permit area. <br />Land Uses. Land uses within the proposed surface disturbed area are cropland, pastureland and <br />rangeland/ wildlife habitat. Mining has occurred within the permit area since the 1930s. Much <br />of the area has been previously disturbed by surface and/or underground [Wining activities. The <br />Eagle No. 5 Mine has been in existence since 1971. <br />Summary of the Mine Operation Plan <br />Current Operational Status. Operations at the Eagle mines were places. in temporary cessation <br />on December 3, 1995 due to market conditions. Currently, only maintenance and hydrologic <br />monitoring activities are being conducted. The Eagle Mines consist of three underground mines, <br />the Nos. 5, 6, and 9, and a reclaimed surface mine the Williams Fork Strip Pit No. 2 . The Nos. <br />5 and 6 Mines await resumption of mining activities. The Eagle No. 9 Mine permanently ceased <br />mining activities in 1985. The portal azea of the No. 9 is being used for a coal processing waste <br />pile, as approved in the permit application. <br />Permit Area, Disturbed Area, and Production Volumes. The permit area covers approximately <br />6,363 acres. The disturbed area totals 427.4 acres. The surface disturbance includes three existing <br />portal areas; the No. 5 Portals, the No. SA Portals, and the No. 9 Portals. The No. 9 Portal <br />Access to the No. 6 Mine is from within the existing areas of the No. 5 aline. This access is <br />within the SA Portals. It resulted in no new surface disturbance. When reining resumes, the <br />projected maximum annual tonnage for the Eagle No. 6 Mine is 4.0 million tons <br />Associated Facilities. These include: mine dewatering ponds, sediment control ponds, haul <br />roads, conveyors, breakers, silo, loadout, sampler, scale, and mine buildings. <br />Mining Method. The three Eagle Mines are underground mines. The No. 5 Mine extracts coal <br />from the F seam, and the No. 6 Mine extracts coal from the E seam. Tht: operator partially <br />extracted coal from the P seam in the No. 9 Mine as approved in a permit revision application <br />(see findings document of April 9, 1984). Room-and-pillar and longwall mining methods have <br />been used in the mines to extract the coal resource. In the No.S mine, conventional underground <br />techniques are used for developing mains, submains and longwall pane]. entries. Room-and-pillar <br />extraction techniques were used extensively in the past, but recent production mining utilizes <br />longwall mining methods. The No. 6 Mine also used conventional mining techniques for <br />development mining and uses longwall methods within production panels. <br />Transportation of Coal and Waste. A conveyor carries coal from the No. 6 Mine to a silo where <br />it is loaded onto a unit train. Waste rock is conveyed from the portal 5 facilities azea and hauled <br />by truck to the coal processing waste pile in the No. 9 Mine portal area. <br />Control ojMine Water and Surface Runoff. Mine water and surface runoff are handled in a <br />series of ditches and ponds. Eagle No. 5 Mine water and No. 6 Mine water is collected in a mine <br />sump and pumped to the surface in the 7 North Angle well. From the well, the water.passes <br />through atwo-pond system, and then is discharged into the Williams Fork River. Disturbed area <br />
