Permit Area, Disturbed Area, and Production Volumes. The permit area covers approximately <br />6,363 acres. The disturbed area totals 422.0 acres. The surface disturbance includes three <br />existing portal areas; the No. 5 Portals, the No. 5A Portals, and the No. 9 Portals. Access to the <br />No. 6 Mine is from within the existing areas of the No. 5 Mine. This access is through the 5A <br />Portals. No new surface disturbance was caused by driving ramps from the F seam (No. 5 Mine) <br />down to the E seam (No. 6 Mine). If mining resumes, the projected maximum annual tonnage for <br />the 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, rail spur, sampler, scale, and other mine buildings. <br />Mining Method. Three of the Williams Fork Mines are underground mines, while the Williams <br />Fork Strip Pit No. 2 and the Utah Tract were surface mines. The No. 5 Mine extracted coal <br />from the F seam, and the No. 6 Mine extracted coal from the E seam. The permitee 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. 5 mine, conventional underground <br />techniques were used for developing mains, submains and longwall panel entries. Room -and- <br />pillar extraction techniques were used initially. More recent mining utilized longwall mining <br />methods. The No. 6 Mine also used conventional mining techniques for development mining <br />and used longwall methods within production panels. <br />The Williams Fork Strip Pit No. 2 was mined, and portions of the Williams Fork strip pit area <br />reclaimed, prior to 1978 (Exhibit 28). Portions of the Williams Fork Strip Pit area were <br />redisturbed after 1978 with the intention of constructing additional portals to the No. 9 Mine. <br />Mining ceased in the No. 9 mine in 1985 and no portals were driven from the Williams Fork <br />Strip Pit No. 2 to the No. 9 Mine. The Williams Fork Strip Pit No. 2 highwall was reclaimed <br />after cessation of mining of the No. 9 Mine. The Division continues to hold reclamation bond <br />for those portions of the Williams Fork Strip Pit No. 2 that were redisturbed after May 3, 1978. <br />Transportation of Coal and Waste. When the mine was active, a conveyor carried coal from the <br />No. 6 Mine to a silo where it was loaded onto a unit train. Waste rock was conveyed from the <br />portal 5 facilities area and hauled by truck to the coal processing waste pile in the No. 9 Mine <br />portal area. <br />Control of Mine Water and Surface Runoff. Mine water and surface runoff are handled in a <br />series of ditches and ponds. Williams Fork Mines No. 5 Mine water and No. 6 Mine water is <br />collected in a mine sump and pumped to the surface and pumped into a series of ponds along the <br />Williams Fork River, and then is discharged into the Williams Fork River. Disturbed area <br />drainage is controlled by ponds, except for those areas where small area exemptions have been <br />approved. <br />Removal of Topsoil and Overburden. In advance of any mine disturbance, brush is cleared and <br />topsoil is removed and salvaged. Stockpiles are shaped and seeded to establish vegetation for <br />protection from wind and water erosion. <br />Williams Fork Mines 11 Permit Renewal 06 <br />C- 1981 -044 December 8, 2014 <br />
