Re: Comments on the Technical Revision (TR2) for the Frei Pit #3 File no. M-19790165
Mr. Frei,
Thank you submitting this Technical Revision (TR). As Tony Waldron from the DRMS
discussed with you and listed in his inspection report, there is not clear documentation on
the reclamation plan and the post mining land use for the Frei Pit #3. Your TR goes a
long way in clarifying these issues. The original post-mining land use was established as
"undetermined". Though this TR the post-mining land use will be set as
IndustriaUCommercial.
After reviewing the permit file, I think there are some additional clarifications that are
needed.
In the permit file, the site was envisioned to have a 10 acre and a 0.9 acre lake. In a
October 22, 19791etter to the DMG the Operator states that they will submit a TR to deal
with changes/removal to the lakes, to certify that inert fill was used to fill the lakes (Rule
3.1.5(9)), and ensure the proper compaction of that Fll (Rule 3.1.5(9)). Based on your
TR map submission and through a recent inspection, it is appazent there are no lakes
presently on site. In order to process this TR the Division needs additional information
about the change in reclamation pertaining to the removal of the lakes, specifically that
the lakes are no longer part of the reclamation plan. The Operator also needs to submit
the information and certification required under section 3.1.5(9) for the fill that was used
to backfill the lakes and any other fill used on site.
Please clarify if any water structures will be left on site (Rule 6.4.7(2)(c)). The PUD map
includes an "open space" area that may be a pond or wetland, please clarify the post-
mining status of this feature. Will there be any stormwater control structures left on site?
The storage of recycled materials is not included in the mining plan, and recycled asphalt
or other similar materials maybe currently stored on site. Will there be any toxic or acid
forming materials left on site post-mining? If so, describe how they shall be handled and
disposed of in a manner that will control unsightliness and protect the drainage system
from pollution (6.4.7(2)(c)).
