The Division of Reclamation, Mining and Safety received the Technical Revision Application 01 (TR-01) to the
Monarch Quarry, Permit No. M-2000-098. The Division has the following items that need to be addressed prior
to approval of the revision.
1. A new east access road was constructed to access the middle and upper benches of the mining
area. Please provide a description of the new access road including dimensions and a cross
section diagram. Describe any associated drainage and runoff conveyance structures to include
sufficient information to evaluate structure sizing. Please state how the road will be reclaimed
upon final reclamation of the site.
2. The existing sediment pond was split into two separate ponds with the construction of the access
road. The operator states that the west pond appears large enough to contain the required runoff,
and further states that the west pond will need to have an overflow structure constructed. The
sediment pond will need to safely pass the designed flow while still achieving the discharge
standards under an approved NPDES permit issued by the Colorado Department of Public Health
and the Environment. The operator will need to design and construct a spill way structure from
the west pond to achieve the approved discharge standards and ensure that the pond can safely
handle the designed flow. Please provide a description of pond and spillway designs to safely
pass water collected in the west pond.
Please be advised that Colorado Lime Company Monarch Quarry TR-0 1 application may be deemed inadequate,
and the application may be recommended for denial on January 30, 2008 unless the above mentioned adequacy
review items are addressed to the satisfaction of the Division. If you feel more time is needed to complete your
reply, the Division can grant an extension to the decision date. This will be done upon receipt of a written waiver
of your right to a decision by January 30, 2008 and request for additional time. This must be received no later
than the deadline date.
If you have any questions, please do not hesitate to call me at 303-866-4943.
