Coal Mine Waste <br />The 100 year diversion ditch above and running down <br />slope on the northern edge of the fill was inspected <br />and found to be in good condition. The diversion <br />consists of an open ditch above the fill which drains <br />into~a flexible black plastic corrugated pipe that <br />runs down slope and empties in another open ditch at <br />the bottom of the fill. <br />Previous state and federal inspection reports indicate <br />that there was a stability problem on the face of the <br />fill in the past. The inspection party walked over <br />this area during this inspection and found the area to <br />appear stable. No slumps or cracks were found and <br />vegetation was established on the slope. Stability <br />monitoring records were reviewed during the course of <br />the inspection and no problems were noted. <br />There is a small seep at the bottom of the upper <br />bench slope at the north end of the fill. At the time <br />of the inspection the area appeared to be somewhat <br />"boggy" but there was no runoff from the area. Salt <br />deposits are evident as well as iron deposits.The seep <br />is being monitored by the operator. <br />
