Thank you for arranging the August 3, 2004 meeting to introduce and discuss the scope of the
Draft Collom Pit Work Plan for the Baseline Characterization Program, July 2004, WMC.
Attendees were yourself and Juan Garcia of Colowyo Coal Mine ( Colowyo); Jerry Rowe, Geoff
Beale, and Ursula Williams of Water Management Consultants, Inc. (WMC); and Dan
Hernandez, Janet Binns, Kent Gorham, Tom Kaldenbach, and myself of the Colorado Division
of Minerals and Geology (Division). Issues discussed pertained to groundwater, surface water,
and geochemical baseline conditions and data gathering to support mine permitting, to define the
water regimes (groundwater /alluviaUsurface), and to evaluate key hydrologic issues associated
with mine development. Some discussions were:expanded to consider initial permitting
application and operational monitoring. The Division recognizes the phased or staged approach
to potential future mining, and that the characterization of some baseline conditions might be
deferred until portions of the mining plan become more imminent.
Our following comments are identified with the paragraph designations of the plan.
2.1 Land use.
We suggest this paragraph be amended to include a discussion of the existence of other
agricultural land uses within the project area. This information may have an effect on our future
determination of the extent of alluvial valley floors.
Locations and impacts of present and future oil and gas operations, and of past and present
mining operations, might be included in your site condition evaluations.
2.6 Proposed Operation

It is stated in this section that material from the 'initial box cuts will be placed as valley fill (a
type of excess spoil fill) in Little Collom Gulch, .and that the exact footprint of this valley fill has
