in nature to other development waste previously stockpiled on site. Experience on site dictates that the makeup of <br />these materials and the analysis of the coal is not indicative of the components that would potentially lead to acidic <br />runoff or adversely affect groundwater quality. Each of these stockpiles has the appropriate controls to capture <br />runoff applicable to the NPDES permit. The mine has a long history of stockpiling coal without encountering <br />spontaneous combustion. <br />During mining the coal refuse will be disposed of permanently by conveying it to the RDA. The RDA facility is <br />described in detail in the later sections of this permit application. Development waste is disposed of in a <br />Development Waste Disposal Area (DWDA) located south of Highway 12, and will be hauled to the West DWDA <br />upon approval of TR -65. Technical revision No. 60 provides for the installation of culverts to create a conveyor <br />corridor from the DWDA to the RDA beltline. MR -101 provides for the installation of the conveyor between the <br />DWDA and the RDA beltline. A belt feeder, 500 foot long beltline and one hundred foot long elevating conveyor <br />will be utilized to convey the development waste to the RDA conveyor. <br />If the rehabilitation reveals insurmountable mining issues there is the potential that the mine would not be re- opened. <br />If this occurs, the equipment necessary to convey the waste to the RDA would be obtained through a short term lease <br />agreement and all stockpiled material would be conveyed to permanent storage in the RDA. <br />Bonding as described in RN -05 dated 01 -26 -2009 is in place to haul raw coal and clean coal stockpiled on site to the <br />development waste pile. Without the startup of mining, the stockpiles will have minimal material to be relocated. <br />The stockpiles are currently empty with the exception of 1,180 ccy (1,400 Icy) of pond cleanings. Temporary <br />storage of 10,000 ccy of development waste in addition to the pond cleanings would require relocation of 11,180 ccy <br />(13,250 Icy) of material. The bonding in place is adequate to cover the cost of relocating all of this waste to the RDA <br />using a temporary conveyor or haulage to a DWDA south of Highway 12 should one be approved. <br />Table 18a lists the volumes and costs associated with the stockpiles covered in the bond calculations compared to the <br />estimated cost to relocate the pond cleanings and temporary development waste using the same rates per cubic yard. <br />The current bond amount of $33,410 to relocate the material is sufficient to cover the estimated expense of $15,440 <br />to relocate the temporary waste. <br />Table 18a Reclamation Bond Comparison with Temporary Stockpile Relocation Cost <br />Stockpile <br />Compacted Volume <br />Loose Volume <br />Haulage Cost <br />Estimate <br />(ccy) <br />(ICY) <br />($) <br />Southeast Coal <br />7,200 <br />8,532 <br />$8,071 <br />Northeast Coal <br />4,750 <br />5,629 <br />$4,722 <br />Raw Coal <br />5,900 <br />6,992 <br />$7,946 <br />Clean Coal <br />7,600 <br />9,006 <br />$12,671 <br />Total Current Bond <br />25,450 <br />30,159 <br />$33,410 <br />Temporary Waste <br />Raw Coal <br />10,000 <br />11,850 <br />$13,470 <br />Clean Coal <br />1,180 <br />1,400 <br />$1,970 <br />Estimated <br />11,180 <br />13,250 <br />$15,440 <br />Other coal processing support facilities are required and have been constructed at the site.
