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 <br />inspection and the facts or evidence supporting the enforcement action. <br />This was a complete inspection of the Sunlight Mine conducted by Erica Crosby of DMG. The <br />mine is a bond forfeiture site, therefore, no company representative was present during the <br />inspection. Weather conditions on site were overcast and warm. It was slightly raining during <br />the inspection Ground conditions were wet. <br />Roads The upper road continues to be blocked by a small berm located at the entrance of the <br />road and appears to be obstructing vehicles from gaining access on the bench. The lower road is <br />well vegetated and access is limited. <br />Hydrologic Balance The upland diversion ditch breach near the road has not progressed since⢠<br />the last inspection. It appears that runoff from the recent rains is flowing down the breach and <br />along the access road. Sediment has accumulated on the lower bench of the road, roughly 50 <br />feet south of the intake portal. The gullies down the slope are roughly 1 foot to 2 feet deep <br />through shale and sandstone rock. Little vegetation is in place to stabilize the slope. The upper <br />portion of the ditch is generally in good repair. <br />The sediment pond was full of sediment, roughtly 1.5 feet from the principal spillway. Water <br />was noted in the pond, but was not discharging from the primary spillway. The berm at the <br />lower fan area was intact. <br />Backfilling & Grading The backfilled portals and fan appear stable. No subsidence features <br />were noted. <br />Processing Waste A few of the timbers on the east end of the pile were deposited in the road <br />ditch, most likely due to the summer rain storms. Refuse material continues to be washed <br />through the timbers and collected in the road ditch. The refuse evetually leads to the sediment <br />pond. The remaining timbers in the crib wall showed no signs of major instability, but some of <br />the timbers appear weak. Gullies one to two feet deep were noted throughout the pile and <br />smaller rills were noted throughout the entire pile. <br />Revegetation The upper mine bench is dominated by coal fines so very little vegetation was <br />noted on site. The upper portion of the mine site consists of mainly cheatgrass, shrub clumps, <br />intermediate wheat grass, Canadian thistle and other unknown weeds. The lower portion has <br />less coal fines, but a lot of mine debris. The vegetation consists of a higher proportion of <br />established vegetation including intermediate wheatgrass, timothy, yellow sweet clover and <br />some shrubs. <br />
