III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made during <br />the inspection. Comments also describe any enforcement actions taken during the inspection and the <br />facts or evidence supporting the enforcement action. <br />This was a partial inspection of the Edna Mine conducted by Tom Kaldenbach of the Colorado Division <br />of Minerals and Geology. No one else was present. <br />HYDROLOGIC BALANCE <br />Water levels in the West Ridge and Center Ridge ponds were a bit lower than during last month's inspection. <br />Center Ridge pond was discharging a trickle. West Ridge pond level was about a foot below the primary <br />spillway. Koll Ditch was flowing several hundred gpm. <br />As part of the inspection I measured standard conductivity in Trout Creek and the Yampa River at the <br />seven locations shown on the map, below. I was verifying compliance with the Division's material <br />damage suspect level of 1,000 mmhos/cm for streams in northwestern Colorado. I made the <br />measurements within athree-hour period in order to provide a "snapshot" of impacts occurring at that <br />time. None of the values exceeded the 1,000 nunhos/cm suspect level. <br />RECLAMATION SUCCESS <br />Overall, the Edna Mine appeared in good shape. Revegetated areas were browning up; rain is needed. Slopes <br />appeared stable and erosion appeared under control. <br />3 <br />
