It is in SCC's best interest to control fires and prevent loss <br />of coal resource. Burning coal in these areas will be extinguished by removing and mixing the material <br />with noncombustible material to the extent practicable and burial with at least four feet of <br />noncombustible material, if appropriate. Water may be utilized in the coal handling facilities. <br />When exposed coal seams occur in the lower portion of the final highwall, backfill material at the seam <br />locations will be of noncombustible material placed in a manner to provide at least four feet of <br />covering. Reclaimed highwalls shall be monitored visually on a quarterly basis to identify any <br />evidence of burning coal. Should evidence indicate coal seams are burning, SCC shall excavate, <br />extinguish and backfill to the extent practicable, the burning portion of the coal seam. <br />• <br />• <br />TR-50 12 Revised 11/04 <br />
