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. Air Resource Protection: Dust was spilling out of the tops of one of the rock dust tanks located north of RCR No. 33. Mr. Watterson indicated that TCC would be putting small bag houses on the rock dust tanks soon. Dust spillage needs to be kept to a minimum. Reve etag tion: Several areas throughout the mine have been backfilled and graded; 10RT/6MN Valve Junction, FCBH to Pit 1 waterline, and 6MN Reservoir embankment, that will need stabilization/or permanent seed mix. Soil moisture is currently good. TCC conducts regular weed control throughout the mine. White top (Cardaria draba) is apparent this time of the season. Areas that need weed control for White top include areas near the west haul road, Pond B area, Pond C area, Pond F embankment, and the RDA topsoil pile. Weed control measures conducted on the 6MN cuttings pit during the fall of 2008 for thistles have proved quite effective as only a few thistle plants were emerging in this area. TCC should continue to monitor this area and reapply weed killer to the re-emerging plants. Refuse Pile: Waste material placement continues on the south and west areas of the pile. Drainage around the pile appears functional except the northern 100-year ditch. Cover material was placed in the ditch when cover material was being placed on the north side of the RDA. Topsoil has not been laid down yet. Material needs to be cleaned out of this permanent 100-year ditch and the designed ditch configuration needs to be re- established. TCC needs to repair the area that the runoff has cut its own path. Flow from this area still reports to Pond D Support Facilities: 18LT Ventilation shaft pad area construction is underway. The sediment pond has been constructed. Final shaping and seeding of the embankments remain to be completed, as well as rip rap placement and weep hole placement in the primary riser. Wattles have been staked and drainage will drain to the sediment pond. Some additional shaping of the collection ditch on the west side of the pad is also needed. TCC was digging the cuttings pit at the time of the inspection and bringing in loads of rock material from the Seneca gravel pit for pad surface material. The culvert was in place. The contractor on the project, Joe Bower, had some questions regarding the outside slope of the pad. His concern was the approved gradient may be too steep for topsoil placement and successful vegetation establishment. Drilling of the vent holes has not commenced yet. No problems were observed in this area and the project appears to be proceeding as permitted. The propane tanks east of Wash Plant H need to be shown on facilities map. The Ditch ("Panama canal") south of the portal area needs to be updated in the permit but is flowing well and is being maintained well to the sump. The emergency overflow sump south of the Wash plants needs a long term solution. This pool is beginning to dry but recent precipitation events have added to the water volume. 5 of 7 WHITE- File YELLOW-Operator PINK-Specialist
