Coal Mine Waste Piles: Ditch cleaning material has been placed, but not spread, on top of gob pile #2. <br />Bowie Resources employs "Smart Ditch" HDPE ditch liners at various locations throughout the mine site. <br />These work well when drainage can be precluded from undercutting the liner. The drainage routing off <br />of the top of Pile #2 is undercutting the smart ditch and the downstream channel is eroding. All drainage <br />reports to sedimentation ponds; however, this creates a maintenance issue for Bowie. DRMS is currently <br />reviewing Technical Revision application #115 which would reconfigure, rock line, and stabilize this <br />diversion channel. <br />Bowie Resources has installed small straw wattles as a series of check dams along the D -D7 ditch at the <br />top of gob pile #4. The wattles are properly keyed -in and functioning to slow runoff velocity and <br />decrease erosion within the channel. <br />Support Facilities: The facilities area is orderly and well -kept. Belts have been removed from conveyor <br />systems, but the structures remain. Slopes in the area are stable and have very good grass cover. <br />The Terror Creek vent shaft area is stable. The vent shaft is permanently sealed and backfilled, and the <br />pad is fenced to prevent access. Straw bales and silt fence are intact and properly keyed to function as <br />intended. No evidence of off-site sedimentation was observed. <br />Maintenance items noted: <br />• Culvert clean out / repair: <br />o The culvert outlet on the south side of the Fire Mountain Canal Bridge is approximately <br />40% clogged and should be cleaned, and <br />o The culvert inlet routing water from the gob piles to Pond D is damaged. Sediment has <br />accumulated in this sump and the top of the culvert has been bent down, decreasing the <br />flow capacity. Recommend cleaning the sump and jacking the culvert open to ensure <br />adequate flow capacity. <br />• Pond F is due for routine maintenance (pond clean-out) <br />No enforcement actions were taken as a result of this inspection. <br />
