Ill. COMMENTS - COMPLIANCE <br />Eagle Mines C -1981 -044 <br />21 May 2008 <br />Pg2 /3 <br />Hydrologic Balance (cont.): - Sediment Ponds 9 -P2 and 9 -P3 are a series of ponds on <br />the east side of the site for old, reclaimed areas. Pond 9 -P2 contained some water <br />and Pond 9 -P3 was dry (only Pond 9 -P3 is an NPDES discharge point). Both pond <br />embankments were well vegetated and appeared to be stable at the time of the <br />inspection. No erosional problems were noted on either pond embankment at the <br />time of the inspection. There is a belt -lined ditch that connects the two ponds. This <br />ditch appeared to be stable at the time of the inspection. <br />- Sediment Ponds SH -P1 and SH -P2, by the old farm shop, were both dry at the time of <br />the inspection. Both embankments were well vegetated and appeared to be <br />stable. No erosional problems were noted on either pond embankment at the time <br />of the inspection. <br />- Sediment Pond 5A -PI , just below the 5A portals, contained a small amount of water <br />at the time of the inspection. The pond embankment was well vegetated and <br />appeared to be stable. No erosional problems were noted on the pond <br />embankment at the time of the inspection. The ditch from the 100,000 gallon water <br />tank above the portal bench appeared to be stable as well. <br />- Sediment Ponds 9 -P1 and 9 -P6, by the newly permitted solid waste disposal area, <br />were both dry at the time of the inspection. These ponds collect the runoff from the <br />solid waste disposal area and the adjacent refuse pile. Both pond embankments <br />were well vegetated and appeared to be stable. No erosional problems were noted <br />on either pond embankment at the time of the inspection. <br />- Sediment Pond HR -P -1 b (and its presettling cell HR -P -1 a) contained a small amount <br />of water at the time of the inspection. Discharge from this pond is through a gated <br />valve, which was closed at the time of the inspection. The pond embankment was <br />well vegetated and appeared to be stable. No erosional problems were noted on <br />the pond embankment at the time of the inspection. <br />Backfilling and Grading: - The backfilled #4 portal area appeared to be stable at the <br />time of the inspection. There was no noticeable settling and there were no erosional <br />problems. <br />- The solid waste disposal area where several demolished buildings have been buried <br />has been backfilled. The area was well graded and there was no settling in the <br />backfill. This area was just backfilled so it will be watched closely. It appears that less <br />than half of the permitted area has been disturbed. <br />Processing Waste: - The refuse pile by the solid waste disposal area vas ,,"vell graded' <br />and appeared to be stable at the time of the inspection. The pile appears to have <br />positive drainage and there was no water pooling on the surface of the pile. There <br />were no erosional problems noted at the t[ i e of the inspectic <br />Support Facilities, it rlal gi; �: _ _ _ i' erev p - <br />`-- <br />f <br />pi -ms s t,'c=re ;- <<�t�- <br />
