Colorado pikeminnow (formerly sgawfish), Humpback chub, Razorback sucker, Black-footed ferret Mustela
ni es), and Canada lynx.
Review of habitat preferences for the identified species indicates that preferred habitat does not exist within the
planned surface disturbance or subsidence areas, so the potential for impacts on these species is minimal. No
significant water depletions are anticipated as a result of the proposed mining operations, therefore, no impacts are
anticipated for the endangered fish species identified. Habitat for the boreal toad typically occurs at elevations
exceeding 7,500 feet. All disturbance and activity associated with this project will occur at elevations well below
7,500 feet. Lastly, the project area is generally too low to provide suitable lynx habitat during most of the year.
There is some potential that lynx could utilize some of the higher areas for winter habitat, however, the mining
operations should not impact the potential for lynx to utilize these areas during the winter months.
Given the information summarized above, TCC has determined that the mining operations described in this
application will not jeopardize the continued existence of any Threatened or Endangered species listed pursuant to
Section 4 of the Endangered Species Act of 1973 (16 U.S.C. 1533) or the Non-game, Endangered or Threatened
Species Conservation Act (Section 33-8-101 et seq. C.R.S. 1973), or result in the destruction or adverse
modification of critical habitat of those species.
