Colowyo C-1981-019 14 December 2005 Pg 2/3 Hydrologic Balance (cont): -The Rail Loop Pond (NPDES 006A) contained water approximately three feet below the riser pipe and was not discharging at the time of the inspection, There is a pile of coal fines/dirt beside the pond from cleaning out the train tunnel. This will be hauled to the West Pit and placed with the other fines/dirt. The embankment was well vegetated and stable and there were no erosional problems noted. -The Stoker Siding Pond (NPDES 005A) contained water several feet below the discharge pipe and was discharging through the weep-hole (just an immeasurable trickle). The embankment was well vegetated and stable and there were no erosional problems noted. - The Work Area Pond (NPDES 002A) contained water approximately five feet below the riser pipe and was not discharging at the time of the inspection. There was no discharge from the Wash Bay Pond into this pond during the inspection. The embankment was well vegetated and stable and there were no erosional problems noted. -The Wash Bay Pond (not an NPDES discharge point) contained water several feet below the emergency spillway, This pond is designed as a containment pond and discharge to the Work Area Pond triggers testing for BTEX. This pond is also used as a storage pond for water for the haul roads. The emergency spillway was stable and in good condition and appeared to be functioning as designed. The embankment was well vegetated and stable and there were no erosional problems noted, -The concrete sediment traps at the wash bay were both full at the time of the inspection but not discharging at the time of the inspection. These sediment traps discharge into the Wash Bay Sediment Sump. The Wash Bay Sediment Sump was full but was not discharging (into the Wash Bay Pond). The oil booms were in place in the middle of the pond and by the discharge. The embankment was well vegetated and stable and there were no erosional problems noted. Support Facilities: -The facilities area was in good condition at the time of the inspection. No problems were noted with the area. - The Gossard Loadout was also in good condition at the time of the inspection. Work had been done to clean out the train tunnel, The train tunnel material has been placed by the Rail Loop Pond and needs to be hauled to the pit for disposal. -There was a fire (actual flames, not just ahot-spot) on the coal stockpile by the West Pit. The loader operator was notified and immediately went to the location to take care of the problem. He was removing the burning material, spreading it out on the pad and driving over it to put out the fire. Topsoil: -All of the topsoil piles observed were well vegetated and stable. No erosional problems were noted on any of the piles. All of the piles had topsoil signs in place.
