2.05.3 <br /> <br /> <br />RN-04 2.05 - 63 - 02/17 <br /> <br />On December 31, 2014, the Applicant had an aerial survey of the gob piles <br />performed. The contours generated by this survey were compared to the <br />final projected contours of the gob piles. The resulting calculation <br />demonstrated there are approximately 1,723,000 tons of remaining storage <br />in the gob piles. To be conservative, this number was reduced by 10% for a <br />resulting capacity of 1,550,000 tons. <br /> <br />The 2015, 2016 and 2017 gob production is projected to be 705,153 tons. <br />The Applicant has adequate gob pile capacity to complete the permit term. <br /> <br />Gob pile #1 was designed by WESTEC. See Volume IV for design details. <br />Coal mine waste pile numbers 2, 3 and 4 were designed by J. E. Stover & <br />Associates, Inc. See Volume IX for design details for pile numbers 2 and 4. <br />Design details for pile number 3 are located in Volume XI. <br /> <br />Non-Coal Waste Storage <br /> <br />Non-coal waste will be stored at the portal level. Three concrete walls will <br />be constructed to form the storage area. The walls will form a u-shape. The <br />storage areas will be approximately 20-feet wide, 30-feet deep and the walls <br />will be 6-feet high. Commercially available dumpsters may be used in lieu of <br />the concrete structure. The typical refuse stored in these areas will be <br />paper, lumber, pipe, supplies, cardboard etc. A local contractor will <br />periodically remove the non-coal waste from the storage areas and haul the <br />refuse to the Delta County landfill. Non-Coal waste may also be stored in <br />dumpsters located: 1) near the office/dry; 2) near the shop/warehouse and; <br />3) near the material storage areas. <br /> <br />(9) Return of Coal Mine Waste to Abandoned Workings <br /> <br />The applicant has no plans to return coal mine waste to any abandoned <br />workings.
