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. Fish Creek Vent Shaft(FCVS)was not pumping at the time of the inspection. Pit 1 elevation has continues to maintain a fairly steady-state freeboard prior to flowing to Pond D. Pond D was not discharging through the flume. However, a fine trickle was noted at the flume that appeared to be emanating from under the flume. Mr. Watterson agreed that TCC will seal this minor flow. The flume had been set in concrete. It appears that there is a small amount of flow piping under this concrete base. Bentonite may be able to seal this. Ponds throughout the mine were in good condition. Pond B was discharging a small amount—0.02 on the staff gauge. TCC has added additional gravel at Pond B outfall to stabilize this marshy area. TCC continues to bury the Mine Water transfer lines from FCBH to Area 1 Pit, from FCBH to FCM-2, From 1 ORT to Junction to 6MN line, 1 ORT to Foidel Creek. TCC anticipates completion of burying of the lines prior to winter weather setting in. The Million Gallon Tank at the PM Bay was overflowing at the time of the inspection. Overflow water flows to pond G. TCC stated that the shut off valves have been troublesome at the tank. This has been an ongoing problem and becomes a safety concern during the winter months due to ice build up. The shut off valve for the Million Gallon Tank needs to function properly. TCC needs to resolve this maintenance problem. The NW B-O-B ditch continues to be clean of coal material. TCC has installed orange markers to denote the edge of the Coal stockpile for a visual clue for the dozer operator in seeing the limits of the pile. TCC is continuing construction to the 6MN reservoir. Obtaining acceptable compaction of the clayey foundation material has slowed the work a little. The contractor working on the embankment construction stated that they were close to the design embankment height. The construction of 6MN pond appears to be in accordance with the approved plans at this stage of the operation. Processing Waste: TCC is filling up the southern and central portions of the RDA. Refuse piles are being end dumped along the west active area. TCC plans to expand west of the current RDA road to the approved western limits of the pile. This westward expansion will require moving of a powerline, construction of a temporary roadway and removal of cover material. The area had previously been stripped of topsoil. TCC is preparing to cover the north slope of the RDA. The SE slope of the RDA has been graded as well. TCC anticipates submittal of a revision to the RDA to the east. This revision has not been received by the Division yet. e to Est— '�jv� Topsoil: 1 ORT topsoil pile has been shaped. Seeding of this topsoil pile and the 6MN reservoir pile are still needed this fall. 6MN topsoil stockpile has been sprayed for Canada thistle. Revegetation: TCC is working with a contractor for seeding of the buried waterlines, new or reshaped topsoil piles, pond embankment, and the north outslope of the Stoker expansion area. A winter wheat crop is being added to the seed mix to act as a nurse crop and help stabilize the soil until the seedmix 4 of 7 WHITE-File YELLOW-Operator PINK-Specialist
