RECLAMATION PLAN EXHIBIT E (cont)
material is placed tends to compact the filled area so settling
is not a problem and the area once filled will be adequate for
the end uses proposed. In most cases the little settling that
does occur can be corrected by grading the surface within 3 year
of final filling. Albert Frei & Sons has not experienced any
subsidence problems their other facilities that are using this
type of inert fill material and we do not expect any at this one.
As Phase 1 is filled with wet fines that are by-products of the
washing operation. These fines will compact, at a rate
commiserate with the nature of the fines . We know of no
equipment that can be used to compact this type of material so no
compaction will take place in Phase 1 other then the natural
compaction that occurs as the wet material fills the hole.
If Option 1 (See Figure E-1 & E-2) is used and the site is to be
revegetated then, a final topsoil cover, averaging 8 inches will
be placed over the site to provide a seedbed. This will mean
that the total cap depth will be a minimum of 10 feet deep. The
removed topsoil and dirt gleaned from the imported material will
be stockpiled around the setback/perimeter of the mined area or
placed on a finished area as it is received. This is designed to
minimize the effect of mid-plan stoppage . This will place the
topsoil where it is needed for reclamation and will reduce the
distance it has to be hauled when needed. Usually, this will
mean it simply has to be shaped and graded to complete recoiling
and seed bed preparation. If Option 2 (See Figure E-3) is used
then the Industrial/Commercial areas will be temporarily seeded
with the approved grass mix until they are developed, so they
have a protective cover until they are developed.
Option 1
This reclamation plan calls for backfilling the site as described
and seeding the areas disturbed with the approved seed mix. The
areas that are not disturbed will be left as is . The final end
use would be pasture . If backfilling ended before backfilling on
the site was completed the side slopes would be graded 3h to lv
and seeded. Certification of the slurry walls would be sought to
address the evaporation loss issue and the areas within the lined
area would be reclaimed. This way the Division would not have to
