The DMR's for the first quarter of 1997 <br />showed no discharge. The only sedimentation pond for the permitted area was last inspected and <br />reported on by the company on 1/30/97 and the pond was in compliance. The pond was certified <br />on 11/15/95. Groundwater monitoring was terminated in January 1995. <br />The site is in good condition. Vegetation has been established on the backfilled area, but <br />revegetation of the diversion and pond has not been as successful. There is a small area of what <br />appears to be settling along the reclaimed highwall line or the upper limit of disturbance. This <br />settling is not in violation; no wall is exposed. <br />
