• <br />n <br />U <br />n <br />U <br />structure. (Total length -about 275 <br />Z. Storage conveyor: 42° conveyor which carries screened coal from the <br />end of the slope belt conveyor to a raw coal storage stockpile. (Total <br />length -about 450. <br />AA. Security Building: This portable building (8'x8') will be removed <br />prior to reclamation. <br />BB. Security Gate: The steel security gate will be removed during <br />reclamation. <br />CC. Concrete Retaining Wall (Mice Portal: This concrete wall will be <br />demolished to a level 1.5 feet below the final reclaimed surface. Broken <br />concrete will be used as portal backtill. <br />DD. Portal Area: The portal area comprises approximately 1.6 surface <br />acres at the toes of the slope at the confluence of the two surface <br />drainage basins. The volume of material required to backfill the portal <br />area to approximate original contour was preliminarily calculated to be <br />52,267 cubic yards. <br />BACKFILLING AND GRADING <br />Backfilling and grading will be undertaken to achieve the post-mining <br />topographic configuration. <br />RETOPSOILING <br />Topsoil will be replaced to a finished depth of 12 inches over all <br />disturbed areas. Topsoil replacement operations will be completed after <br />backfill and grading operations. To ensure good contact between <br />replaced topsoil and re-graded material, the surface of re-graded areas <br />will be left in a roughened condition. Topsoil will be replaced using <br />methods to minimize compaction after placement. In areas where <br />compaction occurs, ripping or tilling of the replaced topsoil will take <br />place. <br />REVEGETATION <br />Revegetation Measures <br />Revegetation measures have been developed to meet the goals of <br />providing native, self-sustaining vegetation communities of similar <br />nature and composition as those present in the pre-mining landscape <br />National King Coal, LLC King II Mine <br />Section 2.05.4 <br />Page 4 May, 2006 <br />
