February 10, 2016 C-1982-056/Foidel Creek Mine JLE time of the inspection. These locations are within the 2016 continuous miner sections depicted for the Wolf Creek Reserve on Map #23 that was approved with TR83. OTHER (SPECIFY): Acetone Seep and Site Maintenance items: Adjacent to the reclaim tunnel of the coal stockpile that feeds the Train Loadout, a seep of unknown material was observed by the surface staff of the mine. The seep is on the northeast side of the coal stockpile. TC took appropriate samples of the unknown substance and sent it to ACZ Laboratories, Inc. in Steamboat Springs, CO to have the material identified. According to TC, the material seeping from the ground was identified as Acetone. Brian Watterson sent the Division a Materials Safety Data Sheet for the substance in question and the results of the ACZ Laboratories analysis. TC implemented their spill prevention plan and created a berm to impound the seep material. TC then pumps the material into large container that is suitable to be shipped to the landfill. According to Mr. Watterson, TC is sending the material to the Milner Landfill. TC is unaware of the source of the seeping Acetone and they have hired a Hazardous Material specialist to oversee the cleanup operations. According to TC, they will slowly excavate into the ground where the seep is presenting to try to identify the source. According to Jerry Nettleton, the historic surface mining operation in the area had some type of a shop and/or a storage area near where the seep is presenting. They anticipate a tank or container has ruptured initiating the seep. Work began on trying to identify the source of the seep on Thursday February 11, 2016. Overall, it appears TC is dealing with the disposal of this non -coal waste in accordance with Rule 4.11.4. The Division requests that TC keep the Division informed of the cleanup operation. Pictures of the seep area are below and Figure 5. depicts the location of the seep. Previous Division inspection reports noted the maintenance items listed below. The following is an update on the current status of these items: • In the RDA-ld ditch, a large section of HDPE pipe and wood was observed in the ditch and needs to be removed. o This item remains outstanding and given the large amount of snow in the area, this refuse is covered and would be difficult to locate. Given this, this item will need to be addressed when the snow conditions allow. • WC013 corehole has been sealed and needs to be marked with a marker. o This item remains outstanding and will need to be addressed. • The head -cut in the RDA -lb drainage needs to be repaired and stabilized. o This item remains outstanding and will need to be addressed when the snow conditions allow. • A new gully has formed on the reclaimed slope above the Fish Creek Tipple pond. The site should be repaired and stabilized. o The Fish Creek Tipple was inaccessible at the time of the inspection. However, according to Mr. Watterson, TC was not able to address this issue before the snow conditions made it unfeasible. This item will need to be addressed when the conditions allow. • The Division has not received proof of compliance (abandonment reports) for the following coreholes: WC -026E, WC -026F, WC -026G, WC -027, WC -029, WC -26B, WC -028 and WC -006.
