RE: Dakolios Pit; DRMS File No. M-1984-036; Technical Revision -04 Adequacy Review #2
Dear Mr. Janes,
The Colorado Division of Reclamation, Mining and Safety (Division) received your response to our first adequacy
review of Technical Revision 04. The Division has reviewed the information submitted, and has several items that
will need clarification prior to the Division's approval. The decision date for the Technical Revision is August 4,
2010. If you need additional time to address the Division's concerns, you must request an extension of the
decision date.
Item #1-- Agricultural Area:
1.) During the 1996 Technical Revision (TR-02) process, the Operator did request to backfill a large portion of the
northern lake with inert material. Part (e) of the inert fill notice states the backfilled lake will create a level surface
suitable for agriculture, and the Operator committed to capping the inert backfill with two feet of overburden of
which, six inches of this material was designated as soil. Thus, the Operator should have saved enough overburden
and growth medium on the site to fulfill their commitment. The Division will not approve the request to leave
areas 1 and 3; as delineated on the submitted reclamation plan map, un-topsoiled and not revegetated.
Areas 1 and 3 were measured to be about 34 acres total. These areas will need to be capped with an appropriate
amount of overburden and growth medium to establish vegetation. Please submit a revised map indicating these
areas will be re-soiled and revegetated.
As of now, the Operator is required to cap the remaining 34 acres with two feet of material as described above (18
inches of overburden and 6 inches of topsoil). There is not enough topsoil/growth medium on the site to fulfill the
re-soiling requirement. It is unclear if overburden has already been backfilled in portions of these areas. Please
indicate which areas have been capped with overburden, if any, and identify the location of any overburden piles
located on the site and an estimate of their volume. Please provide an estimate of the amount of overburden and
topsoil that will need to be imported into the site to fulfill the Operators commitments. The financial warranty will
need to be increased in order to cover the cost of importation of this material.
Another option as discussed in the first adequacy review is to withdraw this Technical Revision and submit an
amendment to the permit and update the reclamation plan outlining the intended use of these areas.
Item #2 -- Clay liner of the Northwest Pond:
2.) Based on our conversations and the Technical Revision narrative, the Office of the State Engineers (SEO) leak
test for the clay liner is pending for the northwestern pond. Until the SEO has certified the clay liner, the Division
