III. COMMENTS -COMPLIANCE <br /> Below are comments on the inspection. The comments include discussion of observations made <br /> during the inspection. Comments also describe any enforcement actions taken during the inspection <br /> and the facts or evidence supporting the enforcement action. <br /> This was a Complete Inspection of the O.C. Mine No. 2 conducted by Marcia Talvitie of the <br /> Colorado DRMS on Thursday, 22-Sep-2009 beginning at 12:30 p.m. Weather conditions were <br /> overcast with a chill breeze. <br /> Signs and Markers <br /> • The topsoil stockpile located adjacent to the sedimentation pond is clearly marked with a <br /> sign. <br /> • The mine area upslope of the sedimentation pond was securely fenced and the entrance <br /> gate was closed. <br /> Hydrologic Balance <br /> • The sedimentation pond was dry, and the interior slopes appeared to be stable with respect <br /> to erosion. The emergency spillway was clear, and the impoundment slopes were well- <br /> vegetated and stable. <br /> Fish & Wildlife <br /> • Elk tracks and sign were plentiful throughout the permit area. <br /> Revegetation <br /> • The top surface and outer slopes of the impoundment structure are covered with grasses, <br /> especially smooth brome. Wyoming Big Sage and rubber rabbit brush were also present. <br /> • The area disturbed by installation of the new fence in the fall of 2008 was showing some <br /> growth-pennycress and the weed, Cutleaf Nightshade. <br /> • The western portion of the reclaimed shade has a high percentage of Curly Dock <br /> intermingled with the sage and rabbit brush (Figure 1). No Curly Dock was visible outside the <br /> permit area. <br /> Reclamation Success <br /> • Two large patches of Canada thistle were observed during the inspection, located on the <br /> short hillside east of the portal area (Figure 2). <br /> • Overall, slopes appear to be stable. <br /> • The entire reclaimed mine (both inside and outside the fenced area) appears to be favored <br /> by elk, whose presence may be slowing the successful establishment of vegetation. Cattle <br /> have had access to the unfenced area surrounding the sediment pond. <br /> O.C. No.2 Mine C-1980-002 22-Sep-2009 <br />
