M. COMMENTS-COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. This was an aerial inspection of the Yoast Mine conducted by Harry Ranney of the DRMS. Aerial photographs were taken on November 24, 2007 at approximately 10:30 a.m. Mike Boulay of the DRMS reviewed the aerial photos. Weather conditions were clear and sunny. The majority of the mine site had a light snow covering, particularly on the north facing slopes. Fourteen photographs were taken during the flyover. The reclaimed North Pit and the majority of the Yoast South area were visible in the photographs (see photos attached at the end of this report). Roads The access roads are maintained and appear to be in good condition. Most of the mine site roads were snow covered. Hydrologic Balance Sedimentation Ponds 010, 011 A, 012, 013, and 014 are visible in the photographs. All of these sedimentation ponds are retaining water and the pond surfaces are not frozen over yet. Sedimentation pond inlets and embankments appear stable and no areas of concern were noted at any of the pond locations. Slides &Damage The location of the slide that occurred above Pond 012 was visible in the photographs. It appears that the site of the slide is remaining stable and no new cracking or slumping has occurred. During the last inspection(see inspection report dated 10/17/07), it was noted that significant erosion in the recently placed topsoil had occurred above Pond 012. From the photos, it is apparent that SCC has repaired the rills and redistributed topsoil on the slide area above Pond 012 as requested by DRMS in the October inspection report. Reclamation Success Both the North Pit and Yoast South areas appeared stable with no signs of erosion or other damage. From the photographs, the site appears generally well maintained and no problems were noted with this aerial inspection.
