EXHIBIT D MINING PLAN (coNT)
Note, the floor of the excavation is generally flat and the slopes
into the reservoirs are 3h to lv where mining is complete on the
perimeter. The excess overburden and plant-generated fines, have
partially backfilled Phase lA and 2A. Phase 1 has been reclaimed
and is ready for final development by the landowners . Also, rec-
lamation 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 acre-
age 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 opera-
tion. 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 aver-
age . 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.
