111111. 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 on the west end of LWB-11 and beginning development of 10 left main. The weather was warm, sunny and dry. Roads: The haul roads and access roads were dry throughout the mine site. BME was in the process of adding additional material to the haul road berms to bring them into compliance with Health and Safety requirements. Subsoil material was being used from the RA8 subsoil stockpile. Berms were in place at the top of the subsoil pile. BME had previously been approved to replace a lesser volume of subsoil on the refuse areas. BME indicates they have an excess of subsoil for the RDAs. Considerable volume of RA8 remains available for the refuse area reclamation. Rio Blanco County work crews were working on a portion of RBC road No. 65. Several ditches along RBC road 65 had been cleaned and laid back further and at least 2 culverts had been cleaned out or replaced. Signs and Markers: BME has mine id signs at entrances from public roadways. Reclaimed boreholes are marked with a cemented aluminum cap with the identification number stamped in the cap. Degas wells and Nitrogen injection wells on the west side of LW panels 11 and 10 were inspected and location coordinates collected using a Trimble GeoXT GPS. Reclaimed holes SC-HG56 and SC-HG-59 were reclaimed, had cemented marker in place, but still need identification stamped in the marker. Otherwise markers were as permitted. Hydrologic Balance: Refuse pile ponds RP-5 and RP-2/3 were observed. RP-5 was dry. RP-2/3 pond is composed of three cells. The two side cells contained pools of water. The central cell with the riser & spillway was dry. No problems were noted with these ponds. The operator reported that the mine site received 0.90" precipitation the weekend of June 12-131". The weather has been dry since. GPS points were collected at the spillways of ponds PR-5 and RP-2/3. Pond DP 1 was holding a pool of water well below the discharge level. PP 1 and PP2 were both holding water. Water in these two processing ponds are re-circulated. No problems were noted with any of the ponds. GPS data points were collected at the riser locations for DP-1 and PP2. BME has been implementing sediment controls on active degas wells and nitrogen well sites since the previous inspection. Processing_waste: Refuse areas 2/3/4 and 5 were inspected. During the winter months BME has placed refuse on the 5A pile to allow this material to dewater. End dumped refuse on are 4 had been spread. A large pile stored from the winter months remains at the southern end of RP5. No problems were noted with the refuse piles. 3 of 5 WHITE- File YELLOW-Operator PINK- Specialist
