The west cell of the pond was basically dry at the time of the inspection. <br /> The pond embankment was well vegetated and stable and no erosional problems were noted. <br /> -The ditch along the east side of the RPE is a riprapped ditch. It remains stable and no problems were noted. <br /> -The RPEE sediment ditch was stable at the time of the inspection. The lower portion,where the flume was <br /> replaced with riprap,was stable and no erosional problems were noted. The French drain from the HR-I slide <br /> remediation was seeping at the time of the inspection. <br /> - The RPEE clean water ditch was also stable at the time of the inspection. During the previous monthly <br /> inspection it was noted that water was leaving the ditch for a short distance. This portion of the ditch has been <br /> repaired and the problem has been corrected. There were no erosional problems noted in this ditch. <br /> GENERAL MINE PLAN COMPLIANCE: <br /> -The operator was mining in longwall panel E5.
