EXHIBIT E RECLAMATION PLAN (CONT)
seeding. All top soiled areas will be seeded with the seed mix
described in this plan, and effective weed control measures will be
implemented until the Phase is released from the permit area. As
mentioned in the Mining Plan, if the reservoir phase acreage is not
released from the DRMS permit, and the landowner constructs
developed water storage facilities that are not in this reclamation
plan, then L.G. Everist will file a Technical Revision to
incorporate the changes .
RECLAMATION PLAN FOR BACKFILL AREAS
This section covers reclamation on the developed water storage
reservoirs in Phase 1A, 2A, 4A, 4B, AND 5A. The 5 areas have
commercial deposits of gravel but are too small or too shallow to
develop as water storage reservoirs . It was also determined that
with the amount of overburden on the reservoir areas, there is not
a large enough demand to sell all the overburden that will be
stripped. The mining plan calls for leaving the side slopes of
these areas graded 3h to 1v when mining ends to leave a stable
slope during backfilling and so they would not have to be graded if
backfilling does not fill them completely. They will then be
backfilled using the excess overburden from the initial stripping
of a phase and the fines generated during processing of the raw
sand and gravel . At any given time, backfilling may be taking
place on 2 or more Phases as shown on the MAP EXHIBIT C-1 - MINING PLAN
MAP.
The intent is to fill Phase 1A, 2A and 4B to their existing
elevations . Phases 4A and 5A may be filled above the original
grade in some areas to dispose of excess overburden.
Estimates show that it is possible to complete the backfilling
in these Phases as shown on MAP EXHIBIT F - RECLAMATION PLAN MAP -OPTION A
and OPTION Bif the amount of overburden is present . At a minimum,
each backfilled Phase will be backfilled to a level at least 2 feet
above the highest ground water elevations if there is not
sufficient material to bring them back to their original elevation.
once backfilling is complete in a Phase, an average of 6-12 inches
of topsoil will be spread over the disturbed area and it will be
seeded as cropland during the next planting season.
Optional Reclamation Plans
Note that all changes connected with the following optional
plans will take place within the permitted boundaries, therefore
not affecting (increasing) the overall acreage of the permitted
area and guaranteeing the allowed use of the Technical Revision
process for these changes .
