:~ <br /> <br />General Conments - Continued <br />No problems were noted with any of the support facilities located at the mine. <br />Sediment pond extension work has been completed. What was thought to be a <br />slump at the northeast corner of the pond during the February, 1985 inspection <br />was actually a pile of excavated material from the area where the pond was <br />extended. Snow cover during February had made accurate observations <br />difficult. The pond was being discharged at the time of the inspection. Pond <br />re-sizing was necessary to accommodate storage capacity for both the 10-year, <br />24-hour storm event and periodic mine water discharge. The diversion ditch <br />system above the surface facilities area was functioning properly at the time <br />of the inspection but needs to be cleaned out as soon as possible in a few <br />places in order to maintain the designed configuration. <br />The interim revegetation on the refuse disposal site still contains a stand of <br />vegetation composed almost entirely of Barley. Few perennial grasses could be <br />seen. The stand does provide sufficient erosion protection, however. <br />The drainage control system at the Delta loadout is controlling runoff from <br />the site. However, some minor improvements need to be made to_maintain the <br />designed configuration Specifically, the culvert at the road crossing over <br />e rm on the north side of the loadout needs to be cleaned out at <br />he outlet end as soon as possible. Additionally, the drainage ditch should <br />be checked to ensure that a positive gradient exists between the outlet end of <br />the culvert and the catchment basin. If not, the ditch will need to be re-cut <br />accordingly. __ <br />The hydrologic monitoring stations at the mine were toured during the <br />inspection. Given the idle status of the mine at this time and the relatively <br />intensive monitoring currently being conducted, the operator may wish to <br />submit a request to the Division along with the upcoming Annual Hydrologic <br />Report to temporarily suspend monitoring at some of the sampling points and <br />reduce the frequency of monitoring at other points. The earth material <br />removed from the location of the recently installed weir below the sediment <br />pond and piled upslope from the weir needs to be smooth graded, seeded, and <br />mulched in the near future. <br />
