COMMENTS
This was a partial inspection of the West Elk Mine conducted by Jim Stark of the Colorado Division of
Reclamation, Mining and Safety. Kathy Welt of the Mountain Coal Company was present in the office and
"Compliance with Mine Plan"portion of the inspection and Jessica Loveland, also with MCC,was present on the
field portion of the inspection. The Mine was not producing coal, as they were completing a longwall move.
They were,however,loading trains and shipping coal from their stockpiles. The weather was warm and sunny
and the ground was dry at the time of the inspection.

Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18:
-Pond SG-1 was almost dry and was not discharging at the time of the inspection. The pond embankment was
well vegetated and stable and no erosional problems were noted. The emergency spillway is an open, riprapped
channel. The spillway was clear and appeared to be stable.
-The west cell of the RPE pond was almost dry and there was a larger pool of water in the east cell of the RPE
pond. Discharge is through a gated valve in each cell. Neither pond cell was discharging at the time of the
inspection. The pond cells are basically incised ponds but the inslopes of both ponds and the small embankment
of the west cell were well vegetated and stable. No erosional problems were noted at either of the cells of the RPE
pond.
-Pond MB-3 contained water approximately six feet below the primary discharge pipe and was not discharging at
the time of the inspection. The pond is an incised pond and it appeared stable with no erosional problems noted.
-Pond MB-4 (the loadout pond) contained water approximately two feet below the primary discharge pipe and
was not discharging at the time of the inspection. The pond is an incised, concrete pond and there were no
problems noted. The presettling sump in front of pond MB-4 was basically full,with water at a level just below its
discharge pipe. This sump was also stable.
