RE: LIBERTY MINE, FILE No. M- 2013 -070, DESIGNATED MINING LIMITED IMPACT 11 OD
OPERATION RECLAMATION PERMIT APPLICATION, RESPONSE TO PRELIMINARY ADEQUACY
REVIEW
Dear Mr. Marshall:
On behalf of Liberty Mining, LLC, Souder, Miller and Associates (SMA) submits this response to
the preliminary adequacy review comments dated January 28, 2014, prepared by the
Department of Natural Resources Division of Reclamation Mining and Safety (DRMS). The
response follows the order of the January 28, 2014 comments.
Exhibit C
1. Liberty Mining commits to submission of a technical revision to address the methods
to be implemented to address a ground water issue should quantifiable /excessive
ground water be encountered.
2. Water rights are actively being sought by Liberty Mining to allow the use and /or
evaporation of captured stormwater falling on the surface of the operations.
3. The stormwater management plan and preliminary Drainage Report prepared by a
Professional Engineer as requested by DRMS is included with this response as
Appendix A. The final, Professional Engineer - certified drainage design plan
including construction drawings will be prepared contingent on permit approval and
will be submitted for DRMS approval prior to any construction work.
4. Rule 6.3.3(1)(m) is addressed in the application in Exhibit C, Mining Plan. Ore and
minerals removed from the mine and brought to the surface will be placed and
contained on a concrete ore storage pad. The mined materials will be held on the
ore storage pad until an adequate amount has accumulated for transportation off site
to a processing facility. No processing of the ore or minerals will occur on the mine
site. The ore storage pad structure will consist of a box -like structure dug into the
surface grade, with reinforced concrete walls, a downward sloped concrete floor, and
a concrete drive -over berm across the entrance to prevent water from flowing down
into the storage pad structure, to allow placement of ore as brought to the surface,
and to facilitate the loading for transport off site for processing.
