III. COMMENTS - COMPLIANCE Sunlight C-1981-046 Pg 1/1 17 May 2010 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 a complete inspection of the Sunlight Mine conducted on 17 May 2010 by Jim Stark of CDRMS. The permit for the site has been revoked and the reclamation was completed by the Division. The weather was warm and overcast and the ground was dry. All of the snow has melted off of the site at this point. Signs and Markers: The Division's revoked mine project sign was along the County Road at the upper portal location of the site. The sign was in good condition. Backfilling and Grading: - The regraded upper portal and road area were well vegetated and appeared to be stable at the time of the inspection. There was no cracking, settling or sliding of the backfill at this time. No erosional problems were noted on the reclaimed slopes. **See pictures at the end of this report.** - The backfilled lower portal and road was well vegetated and mostly stable at the time of the inspection, with the exception of the immediate area of the backfilled portal, as noted below in the "Slides and Damage" section. It appears as though there was someone driving on the lower road but, apart from a few downed willows, there were no problems associated with this travel. **See pictures at the end of this report.** Slides and Damage: - As noted in previous inspection reports, there is some slumping at the lower portal backfill area due to a collapse of the wooden support beams. The block wall that seals the portal is still intact. While the immediate area around the collapsed portal appears to remain stable, there may be a hole developing above where the backfill has collapsed (or it may just be more visible at this time of yed-r). While there was a fair amount of old vegetation above the portal, there was a noticeable depression. I did not venture very close as I did not want to end up inside the portal in the event that it was, in fact, an opening. It appears as though there is runoff routed directly over the backfilled portal, which may have contributed to the collapse. In addition to the collapsed portal, there appears to be an unstable slope immediately to the left (south, basically) of the portal. This slope is very steep and is not vegetated. There are two trees that are at the top of the slope that are falling due to slumping or erosion. There is also (possibly) a large crack approximately half way up this slope. **See pictures at the end of this report.** This completes the 17 May 2010 inspection of the Sunlight Mine.
