EXHIBIT E
RECLAMATION PLAN
The reclamation plan for the Wellington Downs site is a lined water storage reservoir.
Phasing
Reclamation will be concurrent with mining and,therefore, will be completed in phases. The
first phase of reclamation will occur on the south end. As Connell mines the south side of the
property, they will begin backfilling areas not included as part of the final reservoir. As
mentioned earlier, stationary equipment will be placed on the south side for the extent of the
project. Therefore,only the areas not expected to be disturbed for the remainder of the mining
will be reseeded.
The second phase of reclamation will involve sealing and backfilling. On-site overburden and
the claystone bedrock will be used to seal the perimeter of the reservoir and the western edge of
the mining limits to virtually eliminate the infiltration of groundwater into the property. As the
reservoir shoreline and western boundary are backfilled with overburden and claystone, these
areas will be compacted to create an aquitard.
Geotechnical testing was performed to determine the suitability of the on-site claystone material
for the construction of the aquitard liner. These tests included double hydrometer analysis,
Atterberg limits, standard Proctor, and falling head permeability. The results of the tests are
included as Exhibit E-1. The results indicate the claystone material compacted to 96% of
standard Proctor has a permeability of less than 10-6 cm/s and will be a suitable aquitard liner.
Scrapers will be used to place overburden and claystone material along the property perimeter.
Wheel compaction by scrapers will be used to acquire the 95% compaction. The measure of
compaction will be evaluated in the field. This will include an evaluation and possible changes
in the water applications, lift thickness, and compaction method (wheel rolling, sheeps foot
compactor, etc.)
During initial stages of the liner construction, several in-place tests will be done to determine if
the compaction method is sufficient to meet the 95% standard Proctor design. Thereafter
Connell will be conducting regular on-going compaction testing.
During Phases 2 and 3, Connell will establish a visual screen on the north and east sides. The
screen will consist of grass covered three to four foot high berms and fast growing trees and
shrubs.
