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. This was a partial inspection conducted by Janet Binns of the Colorado Division of Reclamation, Mining and Safety(DRMS). Scott Wanstedt of Blue Mountain Energy(BME)accompanied the inspection and represented the operator. The mine is an active underground longwall mine. The operation is currently mining the LWB-10. At the time of the inspection, no coal was being transported along the conveyor to the slot storage building, due to an acceptable stockpile. The weather was warm and dry. The operator---- said that they had only received a minor amount of precipitation the preceding weekend. Roads: The haulroads and access roads throughout the mine site were dry but not dusty. Little traffic was observed along the roadways. Road ditches and grading of roads appear to be in good condition. No problems were identified with the roads. Hydrologic Balance: DPlpond was inspected. Only a small pool of water was present in the pond, well below the discharge elevation. BME had completed construction of a concrete emergency spillway "wall" at the designed elevation. This wall will also act as a buttress to stabilize the rip rap in the emergency spillway channel in the event this pond ever discharges through the emergency spillway. The operator stated that pond DP-1 had not discharged, even through the primary spillway, for at least 2 years. BME has a pump and the primary spillway that allows the operator to recycle some of the water from this pond. Refuse pile ponds RP-5, RP-4, RP-2/3, and RP-1 were inspected. RP-5 was dry, tamarisk had been previously controlled in this pond. RP-4 pond had a small pool of water near the primary riser, well below the discharge level. This pond was mostly dry. RP-2/3 pond is composed of three cells. The two side cells contained low pools of water. The central cell with the riser& spillway was dry. Tamarisk control had previously been implemented on this pond area with no sign of resprouting. Slot storage ponds SS-1 and SS-2 were inspected. SS-1 was dry and the bottom was well vegetated. SS- 2 was damp due to wash down water from the facilities. Several very shallow puddles were present in the pond and cattails were abundant in the pond bottom. There was evidence that tamarisk had been controlled at these ponds, although the operator noted that there were some resprouting tamarisk on the embankment of SS-2. No other noxious weeds were present on the ponds. Processing waste: The refuse piles were inspected. BME is actively spreading refuse on the 5A pile. BME is preparing to spread and compact stockpiled material from the winter months. Some rilling is apparent on the face of the refuse piles, however, this is in accordance with the design and all material coming off the face of the piles are contained in the ditches and ultimately to the sediment ponds. Refuse pile ditches are functioning well and directing flows to the appropriate ponds. No problems were noted with the refuse piles. 3 of 5 WHITE-File YELLOW-Operator PINK-Specialist
