III. 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. General Comments This was a partial mine site inspection, conducted by Dan Mathews of the Grand Junction Field Office. was accompanied during the inspection (with the exception of the inspection of the lower McClane Creek temporary diversion segment) by Walter Whitledge of CAM. Weather was clear and warm; ground conditions had dried significantly since the previous inspection. The mine was actively producing coal at the time of the inspection; Mr. Whitledge indicated that ventilation plan modifications had been implemented to address the hydrogen sulfide problem noted in the March inspection report. Roads Some road maintenance had been completed since the previous inspection, but some maintenance work remains to be done. . , Minor rock and sediment accumulation along a segment of inside road ditch~atthe base of the steep cut-slope, approximately 100 yards up the road from the steel gate (between the portal. area and the sediment pond/soil stockpile areal. The in-ditch sediment trap across from the equipment storage area was partially cleaned out, further clean-out is warranted later this spring/summer, as the material dries out. A large juniper limb had fallen into the ditch just below the sediment trap, and needs to be removed. 1 Anew culvert needs to be installed in the outside road ditch in accordance-with the recent minor revision, approval, to allow occasional access for the power company to read the meter on the power pole. This culvert had recently been delivered, but was not yet installed. Hydrologic Balance There was turbid flow in East Salt Creek, no flow in McClane Creek,, at the time of the inspection. The rock fall that had impacted Culvert "F", on the cut slope above the shop building, had not yet been addressed. Ground conditions in this location have dried since the previous inspection, and it appears that the work to remove the rock and repair the culvert can be done soon, if the warm dry weather continues. When ground conditions allow for safely completing the task, the rock will need to be pulled off the slope and the culvert will need to be replaced or repaired as necessary. The reconstructed sediment pond embankment appeared to be stable, with no evidence of cracking, slumping, or seepage. Some germination of seeded grasses was noted on the embankment. Water level in the sediment pond was approximately 6 inches below the primary spillway inlet. The inlet valve was closed, and the pond was not discharging. SAE silt fence structures at the topsoil stockpile, construction dirt stockpile, and office area were intact and functional. 3
