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 of <br />Minerals and Geology. No one else was present. The site is snowed-in with more than two feet of <br />snowcover. <br />Hydrolo¢ic 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 530 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 level and was not causing an <br />exceedance of the instream sulfate limitation applicable on lower Trout Creek.) <br />Supaort Facilities <br />No problems were evident in the Oak Creek facilities azea. <br />Slides and Damaee <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 snow-covered and appeared stable. <br />3 <br />
