0 <br />(refuse) storage area. All mine refuse is being constructed into a waste <br />bank. The waste bank is currently designed to accommodate up to <br />1,000,000 yd Details of design and construction are located in <br />Appendix 7 and are entitled Waste Bank Design Summary Report, <br />November 1993 revised December 1997, by Don R. May, P.E. The <br />location of the mine waste storage area is shown on Map C -4 of the <br />current King I mine permit text and Mine Waste Pile Design, Plan Layout <br />and Detail Sheet. Standard Proctor tests and nuclear density tests will <br />be performed as detailed in Don May's aforementioned report to ensure <br />that the waste pile continues to meet the designed compaction <br />requirements. Should different types of strata be encountered during <br />mining at the King II Mine, these tests will be repeated to ensure that no <br />significant changes in compaction are allowed. <br />COAL FINES <br />Conveyor belt transported coal arrives at the surface for crushing, <br />screening, storage, and truck loading. The processing of coal is part of <br />the operation of the surface areas of the King II Mine. Four products are <br />prepared for customer use. They are lump coal (6 inches plus), stoker <br />coal (1 x 1/4 inch), nut coal (3 x 1 inch), and mine run coal (2 inch <br />minus). <br />In the processing of these coals, fines are created (1/4 inch minus), by <br />crushing and screening. These fines are mixed with mine run coal and <br />sold. Coal fines are not stored on the surface in large amounts before <br />being mixed with the mine run and sold. Of the processed product, <br />about 10% to 15% of the coal is fines. <br />Mine run, stoker, and lump ( "domestic ") coal is stored in stockpile areas <br />shown on Map King II -007. Mine run storage may amount to 40,000 <br />tons. Open stockpiling is necessary, but large stockpiles are undesirable <br />because of the potential of spontaneous combustion of the coal. Care is <br />taken to keep the coal from being scattered. This is not only <br />advantageous from the standpoint of controlling erosion of the pile but <br />also contamination with spoil materials. <br />RETURN OF COAL MINE WASTE TO ABANDONED WORKINGS <br />No coal mine waste will be returned to underground workings at the King <br />II Mine. <br />SHAFTS: VENTILATION, AIR & ESCAPE <br />Currently, the construction of ventilation, air, escape or other shafts is <br />not anticipated. <br />• GCC Energy, LLC <br />Section 2.05.3 <br />Page 7 <br />King II Mine <br />November, 2009 , r5— <br />
