Runoff or utility water contaminated with oil from shaft sinking operations
would go through an
oil/water separator before being pumped to the reclaim ponds during the construction
phase. Oil
runoff water from fuel storage areas, the construction lay down area, and
around the services
building would pass through the oil/water separator. The oily contaminants
would be stored in hc
tanks or drums at the lubricant storage building until sold to an offsite
processor. Clear water fi
the separator would be pumped to the reclaim ponds for further treatment.

Sedimentation basins also would be built at the MWDF to control runoff. Water
from these basin
would discharge to natural drainage channels adjacent to the MWDF. The runoff
control basins v
be constructed as the tailings ponds were sequentially constructed and closed
(see Figure 1-16 fo
additional detail).

Sanitary Treatment Plant - This system would treat wastewater from toilets,
showers, and
washbasmis in an enclosed, factory manufactured treatment plant utilizing
an activated sludge
extended aeration process. The plant would be located on the eastern edge
of the mine/mill site
would cover 0.1 acres. The plant would treat 25,000 to 30,000 gallons per
day based on an estinim
of 650 people on-site per day. Sludge would be stored in a holding tank for
one or two months ur
removed from the site by a private hauler. Treated water from the plant would
be added to the
discharge pipeline and pumped to Swamp Creek.

ANCILLARY FACILITIES

Wastewater Discharge Pipeline and Swamp Creek Outlet Structure - Treated
wastewater from ti
proposed water treatment plant and sanitary treatment plant would be discharged
to Swamp Cre
about one mile downstream of the County Trunk Highway (CTH) M bridge (Figure
1-2). The pipe
would be constructed of 14 inch diameter, high density polyethylene (HDPE)
plastic pipe and burn

ieast ilive teet aeep. -i-ne pipeline corriaor woula be 6.1 miles long with
corridor easements 50 feet
wide. The corridor would cross through forests and open farmland as well
as 5600 feet of wetland.
No permanent road or pump installations would be required along the pipeline
corridor route. The
concrete outlet for the pipeline would be located in a wetland and placed
level with the ground
surface to minimize erosion.

Potable Water System - Potable water for the facilities would be pumped from
a new well
constructed one half mile southwest of the mine/mill during the first year.
The 18-inch diameter
well, with a pumping capacity of 600 gallons per minute, would pump fresh
water to a 50,000-gallon
storage tank., The potable water system would supply water for reagent preparation
and employees.
Treatment of the potable water is not anticipated. A new well in the construction
support area,
northeast of the tailings ponds, would be used to supply water for soil processing.
Existing wells at
the MWDF would be abandoned or used for monitoring purposes.

Haul Road and Pipelines - The haul road and three pipelines would share a
100 foot wide by 3,800 foot
long corridor between the mine/mill and the reclaim pond (Figure 1-2). The
haul road would be 28
feet wide with a dividing berm confining traffic to the gravel surfaced portion
of the corridor. The
haul road would be used to transport waste rock and construction materials
to the MWDF. The
corridor would cross wooded uplands except for a 190 foot crossing of a wetland.
The topography is
fairly level but steep slopes occur near the reclaim pond.

The three pipelines would be used to transport; (1) the fine tailings slurry
to the tailings ponds,
(2) fine tailings thickener overflow water to reclaim pond B, and (3) return
reclaim pond water to the
ore processing circuits and water treatment plant. The pipelines would be
buried within the
boundaries of the mine/mill site and along the corridor but would be above
ground at the tailings
ponds. Piping needed to transfer clarification pool and underdrain water
from the tailings ponds to
the reclaim ponds and between the water treatment plant, concentrator building,
water tanks, and
tailings thickener also would be above ground. A strip about eight feet wide
would be kept clear of
trees and brush to permit inspection of the pipeline route along the haul
road/pipeline corridor.

Borrow Area - The proposed borrow area is a 40 acre upland site north of
the construction support
area. This area would be disturbed only if soil were needed for reclamation
purposes.
