June 16, 2015 C-1982-056/Foidel Creek Mine JLE • The spillway of the 6MN Sediment Pond has lost its approved trapezoidal design and should be repaired to the design specifications as required by Rule 4.05.9. According to Exhibit 08X, the spillway needs to have a 12 foot bottom width and 2:1 side slopes and needs to be 1.2 feet deep. o This issue has been addressed; the spillway has been reconfigured to comply with the approved designs. • The ditch along haul road C near the railway crossing has been cleaned and rock checks have been installed. The culvert from the repaired roadside ditch under the railway tracks is 3/4 full of sediment and should be cleaned out. o The inlet to the culvert has been cleaned out; however, either the outlet was not cleaned or sediment has collected at the outlet. The outlet to the culvert will need to be cleaned. • The culvert under road C west of the rail tracks is about 1/2 full of sediment and will need to be cleaned. o This issue has been addressed. • Three 8" pipes are identified under the 6MN access road to aid in the drainage of water in the area. These pipes are not identified on Map 24 and no designs for these pipes exist. Please evaluate these pipes and submit the appropriate designs to be included in the permit. Also, these pipes were partially clogged and will need to be cleared. TC could also remove these pipes if they are not necessary. o TC has welded these pipes shut and they are no longer functional. This is no longer considered an issue. • Two unidentified 4" diameter pipes were observed from the Area 1 Pit, under the access road, and to the Pond D side embankment. These pipes were not functioning at the time of the inspection with one housing electrical cable and the other empty. If these pipes are required, identification on appropriate maps is needed. If not required, all non -coal waste will need to be disposed of. o TC has determined that these pipes are not necessary and they will remove them. • Old rail road tracks and wood ties are stockpiled adjacent to Pond B. All non -coal waste will need to be removed and disposed of in a permitted and approved manner. o This issue was discussed with Jerry Nettleton; he indicated the rail road has this material stockpiled at this location in order to conduct repairs as needed. This is no longer considered an issue. • The access road culvert to Pond F adjacent to the warehouse is full of sediment and needs to be cleaned. There is a highpoint in the ditch leading to this culvert allowing for some ponding of water. TC will need to grade and re-establish positive drainage in this ditch. o The ditch has been regraded and is now functioning; however the culvert remains to be cleaned. • An animal has burrowed into the embankment the weir at Pond G is installed into. The hole will need to be repaired. o The hole has been repaired. This item has been addressed. • Wolf Creek Reserve Corehole abandonment reports. TC will need to submit the required proof of compliance reports with the information outlined in Rule 4.07.3(3) for the 30 coreholes abandoned in 2014. The Division requested this information by May 15, 2015. I spoke with Mr. Nettleton about this issue and he indicated that due to layoffs, the environmental staff is still working on completing this report. The Division will check the status of this during the next regular inspection. o TC has prepared an abandonment report for these coreholes and intends to submit this information Number of Partial Inspection this Fiscal Year: 8 Number of Complete Inspections this Fiscal Year: 4 Page 12 of 15
