in nature to other development waste previously stockpiled on site. Experience on site dictates that the <br />makeup of these materials and the analysis of the coal is not indicative of the components that would <br />potentially lead to acidic runoff or adversely affect groundwater quality. Each of these stockpile sites has <br />the appropriate controls to capture runoff applicable to the NPDES permit. The mine has a long history of <br />stockpiling coal without encountering spontaneous combustion. <br />During mining the coal refuse will be disposed of permanently by conveying it to the RDA. The <br />RDA facility is described in detail in the later sections of this permit application. Development waste is <br />proposed to be disposed of in a Development Waste Disposal Area (DWDA) south of Highway 12. The <br />technical revision requesting approval of the permanent disposal area will be submitted prior to the <br />temporary storage of development waste. <br />If the rehabilitation reveals insurmountable mining issues there is the potential that the mine <br />would not be re- opened. If this occurs, the equipment necessary to convey the waste to the RDA would <br />be obtained through a short term lease agreement and all stockpiled material would be conveyed to <br />permanent storage in the RDA. <br />New portals will be constructed in order to achieve targeted production rates. The portals will be <br />located southeast of the silos and will be known as the Bates Portals. Initially the portal face -up will be <br />!, developed and --425 foot long slopes will be driven to the Blue Seam. Blue Seam mining will be <br />addressed in a separate permit revision. <br />Bonding as described in RN -05 dated 01 -26 -2009 is in place to haul raw coal and clean coal <br />stockpiled on site to the development waste pile. Without the startup of mining, the stockpiles will have <br />minimal material to be relocated. The stockpiles are currently empty with the exception of 1,180 ccy <br />• (1,400 Icy) of pond cleanings. Temporary storage of 10,000 ccy of development waste in addition to the <br />pond cleanings would require relocation of 11,180 ccy (13,250 Icy) of material. The bonding in place is <br />adequate to cover the cost of relocating all of this waste to the RDA using a temporary conveyor or <br />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 <br />calculations compared to the estimated cost to relocate the pond cleanings and temporary development <br />waste using the same rates per cubic yard. The current bond amount of $33,410 to relocate the material is <br />sufficient to cover the estimated expense of $15,440 to relocate the temporary waste. <br />Table 18a Reclamation Bond Comparison with Temporary Stockpile Relocation Cost <br />Stockpile <br />Compacted Volume <br />Loose Volume <br />Haulage <br />Cost Estimate <br />(cc) <br />(lc) <br />($) <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.
