After reviewing your letter of February 14, 1983, I have the following
comments. Please address each point in detail prior to the February
23-24, 1983, Board meeting.
A. Exhibit E - Reclamation Plan
1. The final slopes you have planned for the pond are
unacceptable. As stated under Rule 6(1)(f): "In all cases
where a lake or pond is produced as a portion of the
reclamation plan, all slopes, unless otherwise approved by the
Board, shall be no steeper than a ratio of 2:1 (horizontal to
vertical ratio), except from 5 feet above to 10 feet below the
expected water line where slopes shall not be steeper than
3:1."
Please revise your final reclamation plan incorporating the
above specified criterion.
B. Exhibit H - Reclamation Costs
1. The concept behind presenting reclamation costs and posting a
corresponding bond is if the operator ceases mining prior to
planned cessation (as approved in ttte permit) and the operator
is unable to reclaim the affected area, then the State of
Colorado would assume the bond and the responsibility for
reclaiming the area. The staff has developed costs for using
heavy equipment from the Caterpillar Performance Handbook and
the Blue Book Rental Rate for Heavy Equipment. These values
are being used for all permits so that there is confornity
between approved permits for reclamation costs.
