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. Hydrologic Balance: Ponds B, C, D, E,F and G were observed. The discharges of Ponds F,D and G were accessible. Pond D was discharging clear effluent measuring 0.10 on staff gauge at the flume. TDS was measured with the Division's TDSester 1: 970 ppm. Pond F was discharging a clear trickle effluent measuring 0.038 on the 8" flume. Pond G was discharging clear effluent 0.34 on the staff gauge on the V-notch weir. TDS measured 1160 ppm. Pond B was discharging very slowly 0.31 on the staff gauge at the flume. Foidel Creek is running very high and discharge from Pond B is close to flowing back from Foidel creek. 6MN pond had a small breach near the pump. A trickle was running into a small drainage and running several hundred feet through an existing drainage prior to reaching Fish Creek. The water was clean and no obvious sediment was leaving the pond. The operator sampled the pond and initiated the pump as agreed upon with the CDPH&E. The operator patched the breach with a hand shovel. This area will need to be monitored. TDS on the pond near the pump was 830 ppm. RFeaeh fepeif- The Million Gallon Tank at PM Bay was overflowing. This overflow reports to pond G. The operator notified the appropriate personnel to shut off the flow to the tank. Ditches through out the mine site are in fairly good condition. The breach in the Refuse Pile West ditch has not yet been repaired. Flow continues to be diverted into the Pond A access road ditch and continues to report to Pond D. Ditch D-4 south of the portal has been cleaned and reshaped. This ditch is flowing freely. Some additional grading is still needed in the portal access area as there is still ponded water at the switchback. No clogged culverts were found. Flows in the ditches are freely flowing through all culverts. Coal material has been pushed outside of the berm at the Train Load Out. There is at least 75 feet of well vegetated area between this material and Foidel Creek. The terrain is very flat. This material needs to be pulled back to within the drainage control area. TCC is in the process of installing piping and valves to the 6MN million Gallon Tank. The valve placement is located west of IOR borehole &pumphouse and will have a metal manhole to provide access to the valve assembly. Signs Mine ID sign on the East side of the property along Routt County Road No.33 still needs to be relocated to the current permit boundary location. 4 of 5 WHITE- File YELLOW-Operator PINK-Specialist i ;I
