Re: Parkdale Project, Amendment Approval, Permit No. M-1997-054, Revision No. AM-1
Dear Mr. Sheahan:
On April 29, 2008 the Division of Reclamation, Mining and Safety approved the Amendment application submitted to
the Division on October 1, 2007, addressing the following:
Change the Post-Mining Land Use to Water Storage from Range Land. Increase the affected acres from 173 to
200 acres.
The terms of the Amendment No. 1 approved by the Division are hereby incorporated into Permit No. M-1997-054.
The conditions of the Division approval are noted below. Please note that all other provisions of Permit No. M-1997-054
remain in full force and effect.
Stipulation No. Description
1. A visual inspection of the excavated highwalls should be done on a weekly basis for the first 6 months of mining. This
inspection should consist of walking the existing ground and looking for any signs of stress cracks or other potential signs of slope failure.
Some minor stuffing of highwalls is expected on any mine site. The intent of this inspection is to locate potential major slope failures that
could potentially extend back into a structure.
2. A visual inspection should be done anytime a major precipitation event that has saturated the ground using the same procedures. A major
precipitation event defined as a storm that produces an intensity level reaches once in 50 years on the average.
3. If a visual inspection detects signs of potential slope failure, qualified personnel should be contacted to evaluate and recommend
remediation work to stabilize the area.
4. If no visible signs of slope failure are detected within the first 6 months, then the inspection period could be reduced to once per month or
after every major precipitation event.
The total warranty for the site through year 2030 is $4,270,636.OO.The operator wants to post the bond in phases.
The current warranty in the amount of $1,145,736.00 covers the mining and reclamation plan through the year
2012. At present, the Division is holding a financial warranty in the amount of $276,700, please provide a rider in
the amount of $869,036 or a replacement warranty for the full amount so we can release the existing bond. It will
be up to the operator to notify the Division through their annual report or a surety increase revision once the year
2012 arrives or significant changes occur during the mining and reclamation of the pits. The revision will not be
final until the bond is approved by the Division.
