EXHIBIT D MINING PLAN(coNT)
and stockpiled around the disturbed area. Some of this material
will be used to construct a sight berm along the east sides of
Phases lA and 3 to limit visibility from Highway 85 into the active
mining and processing areas . Any material not used for the sight
berm construction will be stockpiled on the north end of Phase 3
for placement in Phase lA once all sand and gravel have been mined.
The berms will vary in height depending on the area to be screened,
with 3 : 1 slopes on each side . During the stripping process, any
structures owned by the Cannon Land Company that will not remain
after reclamation is complete will be removed and disposed of
properly, this applies to all Phases .
Mining will start on the south end of Phase lA and progress to
the north. The setbacks to be used are shown in the table on the
MAP EXHIBIT C-1 - MINING PLAN MAP. The aggregates will be removed and
stored on the Plant Site area in Phase 3 for processing. This
stage will then become a settling pond and excess overburden
backfill area, from the development of the reservoirs in Phase 1,
Phase 2 and Phase 3 .
As mentioned above, the proposed mining sequence may change
due to unforeseen circumstances such as market conditions,
variations in the natural deposit, agreement restrictions with
structure owners, etc . At this time, the plan is to mine them
sequentially from 1 thru 6 as shown on the maps . It may not be
practical to mine Phase 3 until the end of project . If a secondary
haul route cannot be developed for hauling materials from the
eastern area Phase 3 will be used as the Plant Site area throughout
the life of the mine .
Phases 2A, 4A, 4B, and 5A will be mined as described for Phase
lA and prior to, or in conjunction with, mining beginning in the
corresponding reservoir phase in order to provide areas for
disposal of excess overburden and processing fines for those areas .
Sight berms will be constructed along the Railroad ROW on the west
sides of Phase 4 , 4B, 5 and 6 as noted for Phase 3 above .
The following mining methods will apply to all of the
reservoir Phases . Operations will begin in each Phase of reservoir
construction by stripping the area where mining will start .
Initially a 30 acre area will be stripped and periodically as
mining progresses it will be extended so there is approximately 30
acres ready for mining at any-one-time as each Phase is mined. The
topsoil needed for resoiling the above-water areas will be
separated from the overburden and stored around the mining area for
use in reclamation. Once enough topsoil is salvaged to resoil the
above-water disturbed areas with an average of 6-12 inches, the
rest may be sold. These stockpiles will be placed strategically in
