MINING PLAN AND TIMETABLE EXHIBIT D(CONT)
ity into the active mining areas from the transportation corri-
dors . The berms will vary in height depending on the area to be
screened, with 3 : 1 slopes on each side and revegetated using the
approved seed mix.
The active mining area in the reservoirs will remain dry.
After mining is completed, final reclamation of the phase can be
completed, including liner certification, final grading of slopes
and initial seeding for revegetation.
Dewatering as mining progresses, facilitates early testing
of the slurry wall liner, this is required to receive liner ap-
proval certification from the State Engineer' s Office in the Di-
vision of Water Resources .
In general, mining will commence in Phases 1, 2 & 4 on the
south end and work north as shown by the arrows on the MINING PLAN
MAP. In Phase 3, mining will start on the north and work south.
The maximum length and cut/fill volumes of the working face and
side wings in each stage are shown on the MINING PLAN MAP.
The mining setbacks will vary from the permit boundary and
structures as allowed by each agreement for said structures
and/or the Geotechnical Stability Analysis . This analysis shows
that using the 25 feet setback from the slurry wall is adequate
to meet the factors of safety in the DRMS Rules and Regulations,
(see D&A Slope Stability Factor of Safety Results Summary Table
on Page 4 of their report) . The proposed setbacks are shown in
the Setback Table on EXHIBIT C-1 -MINING PLAN MAP
The material will be mined using loaders and excavators
(track hoes) to remove material from the face. The material will
then be delivered to the Plant for processing using haul trucks
or a conveyor system. No blasting will take place at this mine.
Reclamation will run concurrent with mining to control the
amount of disturbed area in the mine at any-one-time. Reclamation
begins in an area once the section is fully mined, and large
enough for efficient reclamation (backfilling, compacting, slop-
ing, soiling, etc. ) that will not have to be re-disturbed.
This pit will be operated year-around by L.G. Everist, Inc. ,
weather permitting. There may be periods when the demands for
material are slow and no mining will take place, creating an in-
termittent operation situation.
Areas not included in the bonded area will remain in agri-
cultural production and the responsibility for weed control and
agricultural area maintenance is retained by the landowners .
