Re: Initial Comments on Potential Impacts of Nix Property Sand and Gravel Mine
Dear Cynthia:
With this letter, we are responding to your request for comments on the potential water
resources-related impacts of the proposed Nix Property Sand and Gravel Mine. We have
focused on impacts to water resources aspects of the Sage Hill Farm.
We have based our comments on a review of the following documents:
• Application For A Use By Special Review (Mining) for the Nix Property Sand And
Gravel Mine -Weld County, Colorado, dated May 2001
• Application for Temporary Substitute Supply Plan -Owens Brothers Concrete
Company Nix Sand and Gravel Mine, Weld County Colorado, dated June 2001
Based upon our initial review and evaluation of the proposed project, we believe that
there are several potential impacts of concern.
General Identification of Water Resources Impacts of Concern
We_ have identified the following potential impacts of the proposed Nix Property Sand
and Gravel Mine on the water resources of the Sage Hill Farm. Our preliminary
evaluation indicates that several of these impacts maybe significant, and that they may
result in material changes to the Sage Hill Farm if they are not avoided or mitigated.
In our opinion, these issues should be addressed in the permitting process for the
proposed Nix Sand and Gravel Mine.
