downstream at this time. However, severe erosion of the steeper <br />• uncompacted piles has taken place. The plan to construct a <br />permanent diversion of the Starkville Gulch away from the spoil <br />areas should only improve the water quality downstream. When a <br />runoff event occurs, it is planned to sample the Starkville Gulch <br />flow upstream from the mine site and also below the mine property <br />to see the effects of the existing site or water quality. The <br />Starkville Gulch is an ephemeral stream which flows only during a <br />rainfall event. <br />It is also planned that the existing spoil piles will be mixed <br />and compacted with the coal processing waste as it is produced <br />from the preparation plant, and placed and reclaimed according to <br />the design specifications. This should significantly improve the <br />site over its existing condition. <br />• <br />The excavation of the permanent diversion should not need to 6e <br />analyzed far acid, alkaline or toxic materials for the following <br />reasons: <br />(1) From the uppermost point of the diversion to the point that <br />the diversion crosses the haul road, (see Map No. 12), the <br />existing path will be used to construct the diversion. The <br />drainage path is not the original drainage channel, which lies to <br />the north and was covered up by excavation from past mining. The <br />existing drainage path has been constructed in loose <br />unconsolidated material that has been previously disturbed and <br />exposed. The proposed diversion would only expand this existing <br />u <br />159 <br />
