• SEDIMENT POND <br />One sediment pond is planned for the King II Mine. The sediment pond <br />is proposed to be located at the southeast corner of the mine bench and <br />sized to contain the 25 year-24 hour precipitation event. Surface runoff <br />will reach the sediment pond through a combination of sheet flow, berms <br />and "V" ditches. <br />TOPSOIL <br />Sufficient suitable topsoil resources exist in the Umbarg soil map unit to <br />provide topsoil replacement depths of six inches. This replacement depth <br />will require stockpiling and ultimate replacement of 16,133 cubic yards <br />of topsoil from the A and B horizons of the Umbarg series. Topsoil will be <br />salvaged and stockpiled using truck/shovel or scraper methods. Topsoil <br />will be salvaged and stockpiled during the operation in a pile constructed <br />adjacent to the sediment pond. The topsoil pile will be stabilized using <br />the seed mix proposed for fmal reclamation. To further minimize the <br />potential for accidental contamination, a berm will be constructed <br />around the perimeter of the toe of the topsoil pile. The berm will be of <br />sufficient size (18" to 24" high, 4' to 6' wide) to prevent machinery from <br />intruding on the topsoil stockpile. <br />• OVERBURDEN <br />• <br />An anticipated 52,267 cubic yazds of material will be removed from the <br />portal area and used to construct the mine bench and base for all mine <br />surface facilities. Additional overburden may be excavated in the <br />construction of the sediment pond. No overburden will be stockpiled as <br />occurs in surface coal mining operations. <br />There will be no surface blasting at the King II Mine. <br />There will be no overburden disposal sites at the King II Mine. <br />COAL HANDLING STRUCTURES <br />Coal handling structures are identified above under production methods <br />and equipment and in Section 2.05.4 Reclamation Plan-Removal of <br />Surface Facilities. <br />COAL MINE WASTE AND NON-COAL PROCESSING WASTE <br />MINE WASTE ROCK DISPOSAL <br />During normal underground mining operations, shale and sandstone <br />National King Coal, LLC King II Mine <br />Section 2.05.3 <br />Page 7 May, 2006 <br />
