DEBRIS DISPOSAL Non -coal non-toxic debris and trash will be used as backfill in the portals. Salvageable steel, concrete and other construction materials will be removed from the mine site to a salvage yard or regulated landfill, if not needed for portal backfill. Any remaining liquid waste will be removed to the appropriate regulated disposal facility. Coal stockpiles will be sold. Any coal residue will be collected with a front-end loader, motor grader, or bulldozer. The residue would be shale and sandstone rock mixed with small amounts of coal. This residue would be ideal for the use of backfilling the portals. All debris, acid-forming and toxic -forming materials constituting a fire hazard are disposed of by a local waste removal company such as Waste Management or Baker Sanitation. Grease, lubricants, paints, flammable liquids, etc. are collected on a regular basis by a certified hazardous material collection company such as Safety Kleen. SEALING MINE OPENINGS In accordance with the requirements of our mine plan, 211.41 (c) 30 CFR, the portals (mine openings or entrances into the King I Mine) will be backfilled -and sealed against inflows of surface water and access by animals or people. Coal stockpile residue on the permit area will be scraped from the surface and used for backfill inside the portals. This will limit the presence of any potential acid-forming or toxic materials in backfilled and re -graded area and minimize potential contamination of topsoil and revegetation. The four portals are each approximately 10 feet wide by 8 feet high. To fill them to a depth of 25 feet will require about 296 cubic yards of material plus a small amount to account for sloughing at the inby end. Total portal backfill will require approximately 400 cubic yards of material. After back -filling to a depth of 25 feet from the portal, the mouth of the portals will be caved to completely seal them. The area will then be backfilled, graded and smoothed over to closely approximate the original contour of the hill into which the portals have been opened.
