Further Remediation Activities Proposed by the Focused Feasibility Study

Additional Remediation Proposed at the Eagle Mine
While considerable work has been accomplished at the Eagle Mine Superfund Site, water quality in the Eagle River below the Mine does not consistently meet the Stream Standards for the Eagle River adopted by the Colorado Water Quality Control Commission, effective January 1, 2009.

A Draft Focused Feasibility Study (FFS) was released for public review by the Colorado Department of Health and the US EPA in July 2011. Prepared by NewFields for CBS, the study evaluates alternatives for meeting the Stream Standards that became effective January 1, 2009.

The Final Focused Feasibility Study was released late summer 2013. That Final Focused Feasibility Study is available at http://www.colorado.gov/cs/Satellite/CDPHE-HM/CBON/1251615994993.

The Final Focused Feasibility proposes to intercept groundwater in the vicinity of the Eagle Mine and pipe that water to the treatment facility. The groundwater that would be intercepted is contaminated with heavy metals from past mining activities.

Limitations of Currently Proposed Remediation Activities
It is important to recognize that the additional work proposed at the Eagle Mine Site only seeks to achieve the Stream Standards currently in effect and that those stream standards are lower than the Table Value Standards for Cold Water Fishery which have been adopted for most of the streams of Colorado that support cold water fishery. Further information about the stream standards and the effect of lower standards upon aquatic life is available elsewhere in this website.
