OFFICE OF SURFACE MINING RECLAMATION & ENFORCEMENT For Release April 3, 1997 Buck Miller (423) 545-4103, ext. 186 SKYLINE COAL MINE PERMIT APPROVED The U.S. Interior Department's Office of Surface Mining Reclamation and Enforcement (OSM) today announced permit approval for Skyline Coal Company's Big Brush Creek Mine No.2 near Dunlap, Tennessee. The mine is a 950-acre extension of the Big Brush Creek Mine No. 1. Both the existing and newly approved mines involve the Sewanee coal seam, southern Tennessee's main coal deposit. Past mining of the seam without special techniques for handling overburden materials resulted in acid- and iron-laden discharges from approximately 50 percent of the sites. For that reason, OSM has carefully scrutinized the adequacy of Skyline's material handling plans, which include a number of measures designed to either prevent acid mine drainage formation or neutralize it at the source. OSM's technical staff believes that the specially designed measures included in the permit will not result in water pollution. Extensive monitoring during operation and reclamation of the mine will be used to confirm that the water quality protection measures are effective. Additional safeguards have also been included in the permit to provide for appropriate bond increases in the event of unanticipated problems involving long-term treatment. The permit also emphasizes that no portion of the performance bond will be released until OSM is assured that the objectives of the hydrologic reclamation plan have been fully met. According to George C. Miller, director of OSM's field office in Knoxville, Tennessee, the surface mining law requires a standard of reasonable certainty that the operation has been designed (1) to minimize disturbances to surface and ground waters and (2) to prevent off-site material damage to those waters. "Those are the criteria applied in reaching this permit decision," he said. Miller said the mining and reclamation techniques required in the approved permit are based on the most up-to-date scientific approach. Similar techniques have thus far proven successful in preventing acid mine drainage from the existing mine, he added. The permit decision applies only to the Big Brush Creek Mine No.2 site, Miller said. The site conditions are unique to this permit and do not directly apply to other evaluations being conducted in other watersheds. "Specifically," Miller said, "this decision cannot be directly applied to a recent petition asking OSM to declare the adjacent Fall Creek Falls State Park watershed unsuitable for surface coal mining."
