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 coal inspection conducted by Jason Musick of the Colorado Division of Reclamation, Mining, and Safety (Division) on 18 May 2010. The weather was cloudy and the mine site was dry during the on-the-ground inspection. Brian Watterson of Twentymile Coal Company accompanied the inspection with Joe Shoemaker joining the inspection. The longwall was operating as permitted in panel 17 Left of the western mining district. No drilling activities were in progress during the inspection. Coal was not being loaded out during the inspection. Signs and Markers Mine Identification signs were in place and exhibited the required information. Topsoil markers were noted in the required locations. Disturbance markers (red and white painted roof bolts) delinated the approximate locations of disturbances. Additional stream buffer zone markers have been installed per the Divisions request at appropriate locations around the train loadout area. Roads Haul roads and access roads were stable and in good condition at the time of the inspection. The 61VIN road will require grading as some rutting was observed during the inspection. Roadside ditches throughout the facilities area were stable and no problems were noted. Roadside ditches were in compliance at the time of the inspection. Hydrologic Balance Ponds G, F, E, C, B, D, and 61VIN were observed during the inspection. Pond 61VIN was holding runoff water with no pumping from 10RT occurring. Pond D was discharging and water was flowing from Pit 1 to Pond D. All Ponds embankments were stable and well vegetated at the time of the inspection. Pond F showed a trickle discharge at the time of the inspection. No discharge was occurring from the Fish Creek Bore Hole Site 115. The sump on the north side of the access ramp at Pond B will need to be addressed to clear sediment to ensure proper functionality of the culvert in to Pond B. This area will need to be maintained to ensure proper runoff to Pond B and to avoid impacts to Foidel Creek. A 4" piezometer is installed at the 10RT site with no readings taken to this point due to magnetization of the casing. TCC personal stated that the freeboard is at -66 feet. Site 62 (Fish Creek Tipple pond) was discharging at the time of the inspection. TCC personal stated that the V-notch weir will be replaced in the future. Currently the discharge is measured using 5 gallon bucket. The collection ditch on the north side of the 61VIN SAE will need to be cleaned and reestablished to ensure proper runoff from the site. Rills were observed along the embankments toward the outlet of the ditch into the collection pond that should be addressed.
