On April 13, 1995 the Division received the additional m terials
required to allow your application for Technical revision o. 1 to
be deemed complete. I have reviewed the application and ave the
following comments and concerns. Please respond to these tame as
soon as possible so that the decision deadline of May 13, 995 can
be met.
1. To cover the area above the pond waterline (approx. 2.0 acres)
with 12" of topsoil would require 3,300 cubic yards of opsoil.
Your application states that only 400 cubic yards are avai able on
site. Please indicate where the additional topsoil will co a from.
note: The overburden could be tested to determine i it has
characteristics conducive to use as a plant growth med'um. If
so, this 1300 cubic yards plus the 400 yards of topso 1 would
amount to 1,700 cubic yards available for re-top oiling.
Because the end land use will no longer be cropla d, the
topsoil depth could be reduced to 6" so only 1,650 cub c yards
would be needed. However, this scenario woul leave
Weaselskin with no material available for any bac filling
should any be required. A commitment to mine in such manner
that will continually maintain the approved final grad of the
pit slopes, as mining occurs, would be required.
Importation of topsoil from off-site sources is an opt on, but
the cost would have to be included in your reclamation bond
and is generally not cost efficient.
2. Please specify which species of grasses will be included in
your seed mix and include an application rate for each.
3. Please indicate the method that you will use to apply ~he seed
and the method you will use to spread the manure/straw mi ture.
4. If Weaselskin does not intend to commit to mining op rations
which maintain the final approved grade of the slopes, please
provide details of the proposed method that will be sad to
backfill any highwalls to the approved final grades. Vol mes and
sources of materials must be provided.
