Hydrologic Balance (cont.): -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. All of the salt cedar
has been cleared from the pond embankment.
- Pond DP-1 contained water at a level just below the discharge pipe and was
discharging through aweep-hole in the pipe. The discharge appeared to be clear
at the time of the inspection. 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-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 Scottj. 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.
- Refuse Pile RP-1 was well vegetated and appeared to be stable at the time of to
inspection. There were no erosional problems noted on the pile.
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.
-The slot storage building and pad area were stable and well maintained at the time
of the inspection. No erosional problems were noted on the pad or outslopes of the
embankment at the time of the inspection.
-The prep plant bench was stable at the time of the inspection. No erosional
problems were noted.
