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 complete 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 extent of LWB-11. At the time of the inspection, coal was being loaded on a unit train at the load out site. The weather was partly cloudy, cool and dry, clearing in the afternoon. Roads: The haul roads and access roads throughout the mine site were dry. Haul trucks were hauling coal waste material to the refuse disposal areas (RDA). BME applied CaC12 to the roadways this spring. Roads are generally treated with chemical dust suppressant twice a year. No problems were identified with the roads. Water spraying for dust control had been conducted in the facilities area and wash plant area. Signs and Markers: BME has mine id signs at entrances from public roadways. Disturbance area markers are still being discussed between DRMS &BME. Currently perimeters of degas borehole pads and nitrogen injection hole pads are not marked. Reclaimed boreholes are marked with a cemented aluminum cap with the identification number stamped in the cap. Hydrologic Balance: The concrete sump on the north side of the Raw Water Lagoon has been installed and the waterline connected and buried. The deck for the pump intake is in place but the piping to the water still needs completion. Final dressing up of the waterline & vault disturbance area is needed and seeding in the approved seeding window remains to be completed. Refuse pile ponds RP-5,RP-4, RP-2/3, and RP-1 were observed. RP-5 was dry. RP-4 pond was holding water a couple feet below the discharge elevation on the riser. 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. Pond RP-1 was dry. No problems were noted with these ponds. Pond DP1 was holding a pool of water well below the discharge level. Ponds RR loop 1, SS-1 and SS-2 were inspected. PP1 and PP2 were both holding water. Water in these processing ponds are recirculated. None of the ponds had discharged this quarter. No problems were noted with any of the ponds. Processing_waste: The refuse areas were inspected. During the winter months BME has placed refuse on the 5A pile to allow this material to dewater. End dumped piles previously stored on RA (Refuse Area) 5A,have been spread and compacted. Compaction reports were reviewed with the records inspection. Refuse pile ditches are functioning well and directing flows to the appropriate ponds. No problems were noted with the refuse piles. 3 of 6 WHITE-File YELLOW-Operator PINK-Specialist
