INSPECTION DATE 11/12/98
INSPECTOR'S INITIALS RCO
This inspection was performed by the Division as part of its monitoring of 110 construction
material permits and to perform a pre-operation inspection of the lands proposed to be
included in the permit as part of the recently submitted 112 conversion application. The
operator was contacted about the inspection, and was present throughout the inspection.
I. Monitoring of the Existing 110 Permit:
The permit ID sign was observed posted at the north entrance to the site. The corners are
marked by steel T-posts sheathed in white PVC pipe.
The topsoil stockpile was enlarged during 1998 when the unmined portions of the pit were
stripped. That material was added to the existing topsoil berm along the west edge of the
permit. It has not been revegetated yet because it will be moved during 1999 after the
permit area is expanded.
The mining in the pit is about 30 feet deep, and expanding to the west. There is still a
small amount of material still available to be mined before the limits of the pit are
reached. There is no new digging on the east or south walls of the pit; they are still at
3:1 slopes and vegetated, though they are not yet topsoiled. The powerpole on the east wall
is stable. A ramp down into the pit is on the north end. The bottom of the pit exhibits no
sign of impounded water.
There are a few stockpiles of crushed gravel on the northeast part of the permit where it is
not yet mined. A wheeled loader was the only piece of equipment present during the
inspection. Virtually the entire permit area is disturbed.
I2. Pre-operation Inspection of the Area Proposed in Conversion Application CN-O1:
The area west of the existing permit area, adjoining the west edge of the permit and
extending to the highway right-of-way, will be added. It is currently level and exhibits
rangeland vegetation.
South of the existing pit is an old mill building, which still houses a significant amount
of dilapidated gold milling and concentrating equipment. The application states that this
facility will be removed from the site prior to any gravel mining activity in that area. The
building is corrugated metal, with concrete floor, steel beam construction, finished offices
and assay lab. It is fully wired and plumbed, but is in disrepair. It is presumed that the
conversion application also includes some type of characterization of the materials still
present in that building, the vats outside, and the tailings pond down the hill to the east.
Outside the metal mill building are a couple conveyors, hoppers and earthen loadout
associated with the operation of the mill. These will also be removed. There are two small
galvanized buildings present which will remain.
There is an overhead powerline passing through the site between the permit area and the mill
building, in addition to the one on the east edge of the existing pit. These will be removed
or relocated out of the path of mining disturbance. The operator is contacting DMEA, the
owner of those structures.
There are a few small ditches along the shoulder of the slope, which currently serve to
convey irrigation water. These will be removed, relocated or piped. This is not to be
disturbed during the first phase of the expansion, but the operator must contact the owners
of those structures prior to any disturbance, and provide any commitments or agreements to
this office-
