EXHIBIT D MINING PLAN(CONT)
agricultural area maintenance is retained by the landowners .
Reclamation will begin once we have enough area for stockpiled
material and the section to be reclaimed will not have to be
disturbed again. Also, reclamation is running concurrent with
mining to reduce the amount of disturbance at anyone-time and
reclamation is following Option A.
Please refer to the MINING TIMETABLES for the estimated acreage
of each area associated with the mining part of this operation.
Mining equipment may include but is not limited to, front-end
loaders, scrapers, excavators, a drag line, dozers, off-road haul
trucks, dump trucks and a water truck. Processing equipment may
include but is not limited to conveyors, crushers and screen
plants . A scale and scale house may be built at the mine during
its life .
As much as possible, the surface drainage will be maintained
in the same direction as it now exists . The proposed sloping plan
for the excavated area should eliminate any concerns of erosion
occurring from the site .
Most of the water used on site will be for dust control used
on haul roads or with sand and gravel processing. Please refer to
EXHIBIT G -WATER for the discussion of how water will be used at the
site, the estimated yearly needs and the source of said water.
The 2 large irrigation ditches that cross the site and the
Cannon return flow ditch will not be impacted by the mining
operation. All interior pit slopes will be maintained with a pit-
ward attitude so that historic drainage patterns can be maintained.
This same slope management plan will prevent any offsite slides or
other disruptions . Isolation berms or ditches will be constructed
around the mine as needed to prevent stormwater from contacting the
disturbed areas . All stormwater contacting the disturbed area will
be retained on site and allowed to evaporate or soak into the
underlying gravel .
No U. S . Army Corps of Engineers, 404 permit is necessary, as
mining will not impact waters of the U.S . While there are ditches
and a non-determined wetland area between them, these areas will
not be disturbed by mining or reclamation.
MINING TIMETABLES
This estimated mining timetable is based on an average year,
and L.G. Everist expects some years to vary widely from the
average. If there are changes in the mining timetable, we will
discuss the reasons for the change in the annual report that
follows the change and modify it at that time if needed.
