I. P,esidual Environmental Impacts
During the first year of mining (1930), 1.7 million
cubic yards of topsoil will be removed and stock-
piled. This will result in elimination of the
evolutionary soil profile and the loss of some
topsoil to c~;ind ar.d water erosion. Establishment
of a cereal Brain mulch crop, the sterile hybrid
wintergraze (Aorotricum), on the stockpile will
mitigate topsoil loss, but an undetermined anount
will be lost during removal, transport, in storage
prior to cover crop establishment and during
reapplication.
In the remaining years of the mine plan, topsoil
will be directly reapplied following regrading.
This will result in the elimination of the evolut-
ionary profile and the loss of some topsoil to
~oind erosion durin; scraping, trar.spor*_ and
redistribution by grading. Some topsoil loss will
occur during, revegetation as a result of accelerated
soil erosion due to wind and/or water. Proper
mulching, cover crops and sedimentation ponds will
minimize such losses.
Removal of vegetation will result in a decline in
the productive capability of the soil due to losses
of plant nutrients and associated organisms to
carry out nutrient cycling. Also, the loss of any
surface organic matter and the deterioration of
plant roots c:ill contribute to accelerated soil
erosion. Reestablishment o`_ the vegetative cover
wi:l mitigate these impacts. Apart from the elimina-
ton of the evolutionary soil profile long term
impacts to topsoil will be slight because, with
revegetation, natural soil forming processes will
be reest:,blished.
