Hydrologic Balance (cont.): -Pond RP-1 was dry at the time of the inspection. The
pond embankment was well vegetated and appeared to be stable. There were no
erosional problems noted on the pond embankment.
- Pond SS-1 was dry at the time of the inspection. The pond embankment was well
vegetated and appeared to be stable. There were no erosional problems noted on
the pond embankment.
- Pond SS-2 contained water approximately two feet below the discharge and was
not discharging at the time of the inspection. The majority of the water in this pond
comes from wash-down water from the slot storage. The pond embankment was
well vegetated and appeared to be stable. There were no erosional problems noted
on the pond embankment.
- Pond DP-1 contained water approximately one foot below the discharge pipe and
was not discharging. The overall amount of water in the pond was very low as the
operator has been pumping water from the pond to the processing plant. The pond
embankment was well vegetated and appeared to be stable. There were no
erosional problems on the pond embankment. The emergency spillway is a
riprapped open channel and was well maintained and stable.
-Ponds RR-1 and RR-2 were both dry at the time of the inspection. Both pond
embankments were stable and well vegetated. No erosional problems were noted
on either pond embankment.
- The roadside ditches along the mine access road and the haul road to the refuse
pile appeared to be stable and well maintained.
- The ditch from the prep plant bench to Pond DP-1 remained stable at the time of
the inspection. No erosional problems were noted in the ditch,
Processing Waste: -Refuse Pile RP-1 is fully reclaimed. The pile was well vegetated
and appeared to remain stable at the time of the inspection. No erosionalproblems
were noted on the pile.
- Refuse Pile RP-2/3/4 was well compacted and stable at the time of the inspection.
There were numerous piles of refuse on the pile and the operator was hauling and
dumping refuse on the pile at the time of the inspection. No water was pooling on
the surface of the pile and it appeared to be properly graded to allow water to flow
to the ponds. No problems were noted with respect to the pile.
-The Operator has stockpiled refuse on pile RP-5a over the winter months. The
stockpile is in the same place it always is, on the southeast portion of the pile. The
refuse stockpile appeared to be much smaller than it has been in the past (which
was confirmed by Scott). The refuse pile was well compacted and stable at the time
of the inspection and no water was pooling on the surface of the pile. The pile was
properly graded to allow water to flow off of the surface of the pile to Pond RP-5. No
erosional or stability problems were observed on RP-5a at the time of the inspection.
Support Facilities: -The loadout structure was stable at the time of the inspections. No
problems were observed. There did not appear to be any commingling of
equipment between the mining and rail operations at the time of the inspection.
