September 18, 2012 C-1981-012/New Elk Mine JHB pond had discharged recently and adequate storage capacity remained. SAE at the cell tower location east of the RDA needs the berm on the east side of the pad built up. Ditch D 15 adjacent to the water intake galley along the Purgatoire River had been filled in with a ramp. NECC cleared this material from Ditch D 15 by the end of the day on 9/20. Material has been cleared from the outlet of Culvert C-8. NECC has recently cleaned D l0A and D 13. The berm along the river at the water intake galley needs to be built up. Ditch D 16 on the north side of Pond 1 doesn't exhibit excess sediment. Culvert C72 outlet needs sediment clean out. Ditch D22 needs to be maintained to the design criteria of 1.8"deep. The current configuration is too shallow. Culvert C-64 adjacent to the Prep plant needs sediment cleaned out. Pond 6 continues to dry. No water is being pumped into Pond 6. Pond 6 has not yet been lined. Pond 7 is holding a pool of cloudy water. NECC has been approved for sediment drying location,but needs to submit additional bond prior to implementing the approved revision. NECC indicated that more sediment clean out from Pond 7 is planned. Pond 7 was not discharging. A pipe has been attached to the outfall pipe and is currently sealed. This arrangement was used when NECC ran all discharge from Pond 7 through a filter prior to discharge. Armoring of the east embankment has not yet been conducted. Bates portal culverts shown on Map13-Sheet 1 are not in agreement with the on the ground conditions. C55, C47, C58, and C47 were not located. Ditch D24A appears to be run in a culvert instead of a ditch as designed. NECC needs to bring this drainage into agreement with the design or provide a demonstration of the culvert sizing. Ditch D24BB appears to discharge into the clean water ditch and does not flow into Culvert C58 and eventually to Pond 7. NECC needs to assure that all disturbed area runoff is treated as designed. The Bates portal conveyor is shown incorrectly on Map 13. NECC needs to update the map. Ditch D24 has been filled in with the clean coal pile. This ditch needs to be re-shaped in accordance with the design. A waterline trench has been opened on the north side of the silos. This trench is pooling water and appears that drainage is not being directed eastward out of the facilities area. Completion on the waterline project is needed. Ditch D24D appears to have been filled with trenching material. Drainage system needs to be restored and maintained. Drop inlet#3 needs to be cleaned out. Ditch system at the Rock bin does not agree with Map 13. Temporary Truck load out is not shown on Map 13. Drainage from Ditch D25 sumps at the Temporary truck load out. Drainage system needs assure runoff makes it to designed ditches and Pond 7. Drainage at substation, Ditch D39A and D39AA need to be brought into agreement with design.
