Subject: Response to Preliminary Adequacy Review-01 for Sundance
Resources, Regular 112 Application, Permit, File No. M-2006-073
Dear Mr. Bird:
Lafarge is in receipt of the Preliminary Adequacy Review-01 comments for our
Sundance Resources Regular 112 Application, File No. M-2006-073. Banks and
Gesso, LLC, has been retained to compile adequacy responses and submit this
response on behalf of the applicant,
This response also includes, for the record, a revised and more detailed plan for
certain technical features of the operation. These revisions include:
1. Pre-mining installation of a slurry wall. To reduce groundwater exposure
and mitigate depletion effects of de-watering operations, the applicant
plans to install a slurry wall around the perimeter of proposed water
storage cells before those areas are excavated. This plan will involve
installation of the wall and maintenance of appropriate setbacks and side
slopes, as a result reducing the total mining plan in corresponding areas.
2. Additional berming. To address visual impacts and other concerns in the
local review of the resource extraction proposal, the applicant plans to
expand berms to include not only screening of the plant and processing
area and Phase 1, but most mining operations as well. The pre-mining
installation of slurry walls facilitates this dedication of additional
overburden to stockpiling as screening berms.
Our responses to comments raised during the adequacy review are given below
in the order in which they were presented, referencing the appropriate Exhibit.
As discussed further below, the applicant intends to submit these responses in
order to meet the March 2, 2007 decision date.
