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. This was a partial inspection conducted by Janet Binns of Colorado Division of Reclamation, Mining and Safety. Mr. Joe Shoemaker of Twentymile Coal Company accompanied the inspection. The mine is an active underground mine. The weather was cool, windy and cloudy, with rain and snow showers in the afternoon. Patches of snow remains on the permit area, but most of the snowpack has melted off. Runoff is actively flowing to the ponds, in the ditches and throughout the mine site. The region has received rain and snow recently. The Mine is just completing a longwall move and is preparing to resume mining. Roads: Roads throughout the mine were muddy but mostly well graded. 6MN access road was driven to the Fish Creek crossing to inspect repairs conducted on the road after the high water runoff in April. Durable limestone gravel was placed in the low portion of the roadway. Joe stated that Fish Creek flowed very high the preceding weekend and flow passed through the gravel stretch without washing out the road. He also related that the main channel culverts were submerged and water flowed through the overflow culverts recently installed by TCC. This portion of the road was in good condition. Much of the washed out roadbase had been pulled out of Fish Creek bottomland, but due to soft conditions some material had been left until area dries. Flow in Fish Creek has come down a foot or more since this past weekends high water mark. No flow was going through the overflow culverts or the gravel portion of the roadway at the time of the inspection. TCC needs to submit a revision to the permit documenting the additions to the roadway. Hydraulic oil spill on the 6MN pad near the pump house continues to be cleaned up. Joe placed additional absorbent napkins on the visible oil patches. TCC has place an absorbent boom and napkins in the inlet of the 6MN pond. This is effective in keeping the material away from the pump at the south east side of the pond. TCC needs to continue to clean up and monitor this spill. Additional grading is needed on the 6MN pad where snow was pushed this past winter. Some snow and dirt material has been pushed off the 6MN pad on the Northwest side adjacent to the shaft heater propane tank. This material needs to be moved back within the drainage perimeter. The main access road into the permit was in good condition and well graded. Drainage off this roadway was collected in the roadside ditches. Haul Road B ditches were functional but need additional shaping. Drainage off Haul Road B is good in most areas but needs some additional shaping due to some soft areas. TCC has talked to the Division the need to permit a change to the Stoker loading turn around area. This location was looked at for potential expansion. Constraints in this area include Foidel Creek buffer zone, Pond E emergency spillway, and powerpoles for the line to New Wash Plant. The Refuse Pile Haul Road ditches are functional and drainage is running down the ditches. The Refuse Pile Haul Road is dry, however ditches do need additional shaping. Haul roads & access roads throughout the site are in good to fair condition. Additional grading is needed near the PM Bay, to the South of the New Wash Plant, and along Haul Road B near Pond B and under the conveyor. Road drainage from Haul Road B runs into Foidel Creek near pond B with minimal settling of the sediment form the roadway. 3 of 5 WHITE- File YELLOW-Operator PINK-Specialist
