(iv) The quality of surface and groundwater within and adjacent to <br />the permit area that may be affected by underground mining. <br />Not applicable. <br />(b) Plan requirements <br />(i) Drainage plan. <br />Train Loadout Drainage Control Plan. <br />The train loadout drainage plan consists of retaining run-off <br />water from the sixteen -acre disturbed area in a 1.8 acre-foot <br />sedimentation pond. <br />Run-off is directed to the sedimentation pond from the train <br />loadout area. The shop area naturally flows by gravity to the <br />sedimentation pond. The western end of the train loadout area <br />near the truck dump station drains over the fill slope to the <br />drainage along the railroad tracks. Run-off from the railroad <br />track drains downgrade to the sedimentation pond. <br />The run-off is contained within a berm on the south side of the <br />spur at the train loadout building. Map 7 shows drainage plans <br />in this area. <br />Coal Stockpile Drainage Control Plan. <br />A sedimentation pond with 0.35 acre-feet of storage volume <br />receives run-off from the coal stockpile area. The "V" ditches <br />constructed around the perimeter and the constructed grade of <br />the area carries run-off to the sedimentation pond. <br />Transportation Facilities Drainage Control Plan. <br />The transportation facilities' drainage has been designed and <br />constructed to minimize erosion, sedimentation, and <br />detrimental effects to surface and groundwater. The theory <br />used is to direct run-off from facilities to sedimentation ponds, if <br />possible, or in order to minimize visual impacts and disturbed <br />RN -07 2.05-38 03/18 <br />
