l 0/7/8 <br />2-10 <br />2.3.2.3 Supply Yard <br />. Concurrent with the philosophy of using one area to act as a <br />staging area for all existing and future Salt Creek mines in <br />this area, one large supply yard will be constructed in the <br />central facilities area (see Figure 2.2-iS). All bulk mater- <br />ial going to the mines will be stored in the supply yard until <br />needed. After being leveled, compacted and graded, the supply <br />yard will be fenced to limit access and graveled to minimize <br />sediment load in runoff. <br />In those areas where fuel or oil will be stored, a Spill Pre- <br />vention, Control and Countermeasure Plan will be developed and <br />kept on file. All fuel tanks will be buried and fuel pumped out <br />of them. <br />2.3.3 Coal Handling Strategies <br />After coal is mined at the face, a series of underground belt <br />conveyors will transport it outside. The mine conveyors will <br />• then empty into a surge bin to equalize outflow. Overland con- <br />veyors to the central facilities area will be fed by the surge <br />bin. At the central facilities area, coal will be processed, <br />stockpiled and loaded onto rail cars. Prior to the construc- <br />tion of the conveyors (see Table 2.2-15), coal will be trans- <br />ported as outlined in the original permit No. C-020-81. <br />2.3.3.1 Coal Conveyor and Surge Bins <br />At the mine site, there will be a surge bin to accept coal from <br />the mines and equalize outflow of material to the central fac- <br />ilities area. Besides controlling the flow of coal from the <br />mines, the surge bin will afford a small amount of reserve cap- <br />acity so that the mine can continue to operate if an outby con- <br />veyor shuts down. <br />Conveyor belts to the central area will run overland from the <br />surge bin. Three flights of belt are necessary to transport <br />coal from Munger Canyon (see Figures 2.2-B.1S through 2.2-S.SS). <br />1i <br />
