SEALING MINE OPENINGS <br />In accordance with the requirements of our mine plan, 211.41 (c) 30 <br />CFR, the portals (mine openings or entrances into the King I Mine) will be <br />backiilled and sealed against inflows of surface water and access by <br />animals or people. Coal stockpile residue on the permit area will be <br />scraped from the surface and used for backfill inside the portals. This <br />will limit the presence of any potential acid - forming or toxic materials in <br />backiilled and re- graded area and minimize potential contamination of <br />topsoil and revegetation. The four portals are each approximately 10 feet <br />wide by 8 feet high. To fill them to a depth of 25 feet will require about <br />296 cubic yards of material plus a small amount to account for <br />sloughing at the inby end. Total portal backfill will require <br />approximately 400 cubic yards of material. After back - filling to a depth <br />of 25 feet from the portal, the mouth of the portals will be caved to <br />completely seal them. The area will then be backiilled, graded and <br />smoothed over to closely approximate the original contour of the hill into <br />which the portals have been opened. <br />GCC Energy, LLC King II Mine <br />Section 2.05.4 <br />Page 18 June 26, 2014 M-22 <br />AP <br />pfoved <br />03 -J41 -2011 <br />
