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.
TCC needs to complete clean up of the hydraulic oil spill at 6MN facilities area. Absorbent napkins are
available and drums for contaminated material are on site. No visible oil was observed at this spill area,
but TCC plans to scrape up affected pad material, and dispose of properly.
The 18RT facilities area spill has had affected pad material scraped up and placed on a tarp. TCC has
taken a sample and is awaiting results to determine proper disposal procedures. Affected material in the
ditch has been removed as well. Runoff from this drill pad runs into a ditch and then to a sump. Spilled
material has been cleaned from the sump. The Foidel Creek Mine area has received precipitation over
the weekend but no discharge occurred through the sump. TORT discharge was continuing into Foidel
Creek. Foidel Creek is running high upstream and downstream of the mining operation. TCC discussed
long term plans considered for the TORT discharge that may incorporate ponds and wetlands systems to
treat the discharge. TCC will be submitting a revision to DRMS for management of this discharge.
TCC reported that they are maintaining in excess of 33.5 feet of freeboard underground at the Fish Creek
Vent Shaft (FCVS). FCVS was discharging to Pit 1 on 5/27. No discharge to Fish Creek was occurring
from Site 115 (FCBH ponds). Reconfiguration of the piping is occurring at the FCBH ponds.
Ponds: Pond B discharging 0.19 on flume. Effluent was clear. Oil booms need replacing soon. Runoff
redirecting at the Pond B access ramp is progressing. TCC has dug a sump on the north side of the ramp,
improved the berm to Foidel Creek, cleaned up sediment on the bank of Foidel Creek, routed runoff to
the sump on the south side of the ramp, and cleaned sediment from the southern sump. The culvert
appears to have too much of a drop to the south. The sump functioned well with the recent rain storms,
but the outlet already needs cleanout. TCC needs to finalize the construction of this sump area and
construct berms or some more permanent barrier to the north side sump.
Pond C was holding water but not discharging. Pond D was discharging 0.35 on the staff gauge at the
flume. Discharge was clear. Pit 1 is discharging to Pond D. A waterline break east of the stoker Loadout
observed on 4/22 has been repaired and no excess flow was observed in this area.
The Million Gallon tank at the PM Bay was not spilling over at 9:30 am, but was at 11:40 am, and at
4:30 pm. Pond G was not discharging at the start of the inspection, but was at 4:30 pm. The automatic
shut-off valve for this tank is apparently faulty again.
Topsoil: Some weed control is needed on a few of the topsoil stockpiles throughout the operation. TCC
has the summer environmental crew starting in the next couple of weeks. The summer crew will be
repairing signs and replacing topsoil stockpile signs throughout the permit area.
The topsoil stockpile at 18LT Ventilation pad is appropriately located, has had a berm constructed
around it, has not yet received final shaping or stabilization seedmix.
