Pond P-3 was inspected and found to be in compliance. This <br />structure has a PVC riser for the principal spillway and a v-notch <br />open channel emergency spillway. <br />P-4 is a detention basin with little or no detention time. This <br />structure accepts run-off from the road above and any discharge <br />from P-3. <br />Ponds P-6 and P-S have been reclaimed in the past. Pond P-5 has <br />one open channel spillway and collects only run-off from the road. <br />Pond P-7 is similar, has only an open channel spillway and collects <br />run-off from the road. <br />Ponds P-l, P-2, and P-7 are addressed in the permit as having been <br />reclaimed. These three ponds however were locatable in the field <br />and appear to require additional reclamation. This problem is a <br />permit defect and must be rectified by the operator through a <br />revision process during the next 30 days. This issue was more <br />completely addressed during the 9-23-94 inspection of the site. <br />See that report for additional information. <br />Water was discharging from Mine #3 below the road and adjacent to <br />the manhole cover at a rate estimated to be 10+ gpm. Field water <br />quality parameters were measured. The temperature was 60 degrees <br />F., and the pH was 6.9. The EC meter was not able to be calibrated <br />properly, so the EC reading of 926 is suspect. <br />The water level in the air shaft at Mine #1 was just below the <br />secured gate. No seeps or other discharge was noted at the Mine #1 <br />area. No evidence of vandalism or attempts at entry were noted. <br />The areas of Mine #1 have been sufficiently vegetated so that no <br />sediment control structures are required. This is evidenced in the <br />permit on pages 4-19i through 4-19iii. In the past the operator <br />has lined the shoulders of the river drainage with straw bales. <br />This is no longer a required measure, however. <br />The Mine #1 water treatment system was thoroughly checked and found <br />to be in good working order. Effluent was being piped from the <br />mine/air shaft and three of the four outlets above the Long Pond <br />were discharging water. Heavy iron deposits were in evidence in <br />the sump where the pipes discharged as well as in the half culvert <br />directing drainage to the Long Pond. The Long pond had both a <br />closed culvert primary and emergency spillway. There was thick <br />vegetation in the pond and sparse vegetation on the pond's <br />embankment and immediately to the south of the embankment. The <br />operator later indicated that the pond embankment had been seeded <br />in the fall of '93. There was no sign of emergent vegetation but <br />numerous weeds such as hound tongue, russian and Canada thistle <br />were observed. As indicated in the previous two inspection reports <br />the embankment will need to be reseeded this fall. One very small <br />seep area was noted next to the embankment. <br />
