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 complete inspection ofthe Edna Mine conducted by Tom Kaldenbach of the Colorado Division <br />of Minerals and Geology. No one else was present. Although much of the snow has melted from the site <br />since last month's inspection, more than a foot of snowcover still prevented access to [he site during this <br />inspection. Only the Oak Creek facilities area could be accessed. The rest of the site was viewed from <br />county roads. <br />Availability of Records <br />Required records were available at the Routt County Courthouse, with the following exceptions: <br />a) 2002 annual hydrology report (recently filed with DMG); <br />b) 2002 reclamation report(recently filed with DMG); <br />c) 4`h quarter 2002 pond inspection report. <br />The records checklist is attached. <br />Hydrologic Balance <br />To assess the impact of possible spoil spring discharge on Trout Creek, I measured field conductivity <br />in the creek upstream and downstream from the Edna Mine. (Snow cover prevents entry into the mine <br />site, so it was not known if spoil springs were discharging during the inspection.) Field conductivity <br />was 140 umhos/cm immediately upstream from the mine, and was 490 umhos/cm approximately 4 <br />miles downstream from the mine. These values indicate that if spoil springs were dischazging, the <br />mine is not causing an exceedance of Trout Creek's 1000 umhos/cm material damage suspect level for <br />irrigation water. (My inspection of the Foidel Creek Mine on the same day found mining's cumulative <br />impact on Trout Creek was below the material damage suspect.) <br />Support Facilifies <br />No problems were evident in the Oak Creek facilities area. The gate was open , so I locked it after <br />calling the operator. <br />Slides and Damage <br />Reclaimed slopes in the Moffat, Center Ridge, and West Ridge areas were observed from County Road <br />29; no problems were evident, although snow cover limited inspection. The Goat Trail was observed <br />from Highway 131. Slopes were free of snow and appeazed stable. <br />3 <br />
