The following listed issues remain to resolve permit requirements related [o the slurry wall and mining
setbacks at the Cooley Reservoir and Fulton Wildlife Area.
1. The draft PSCo license item 17 indicates that slurry wall removal will be required upon CAMAS
abandonment of the site. This condition should be modified to state that the slurry wall is a permanent
facility. DMG is concerned with condition 17 [o [he license because the slurry wall is necessary to
achieve the proposed post mining land use.
2. It is not clear from the language in [he draft license that the mining setbacks proposed by CAMAS have
been accepted by PSCo in the compensation statement at item 23(e) of the draft license. 1 suggest that
the draft license be modified by adding the following sentence or a similar sentence to the end of item
23(a). "The licensee will maintain at all times the mining setbacks from the Public Service Company
right-of-way illustrated in exhibits A-1 and A-2 [o [he license."
The slurry wall costs of $3.00 per square foot are acceptable for [he purpose of determining the amount
of reclamation bond [o be required. Since the applicant has selected [he regulated construction option, a
condition of the permit must be [ha[ plans, specifications, and a quality assurance plan for the slurry wall
must be incorporated into the permit prior to construction of the slurry wall. The operator must also
provide a construction report at the conclusion of the installation and a certification that the slurry wall
was installed in accordance with [he approved plans and specifications.
If these issues are addressed, I would be prepared to recommend approval of [he application as it applies to
the issues 1 was assigned to review. Specifically, the slurry wall, the setbacks, and the stability of the PSCo
right-of-way during the one-percent annual chance Flood.
