Finding of No Significant Impact for the Restoration Plan and Environmental Assessment for the Richardson Flat Tailings Site, Park City, Utah

The U.S. Fish and Wildlife Service (Service) prepared a Restoration Plan and Environmental Assessment (RP/EA) for the Richardson Flat Tailings Site, Park City, Utah.  The RP/EA was prepared as part of a Natural Resource Damage Assessment and Restoration settlement between United Park City Mines, as the Responsible Party, and the Service, on behalf of the Department of the Interior, as the applicable Natural Resource Trustee.  We issued a scoping notice for public comment on November 6, 2012, and issued a draft RP/EA for 30-day public review on the web at and  We issued a final RP/EA on February 8, 2013.  The final RP/EA responds to the public comments we received on the draft.  The final RP/EA is available by request from the Utah Ecological Services Field Office by contacting Larry Crist, Utah Ecological Service Field Supervisor, by phone or fax at the numbers provided below. 

As determined by the RP/EA, we determined no additional response and restoration activities to be necessary at Richardson Flat Tailings Site – Operable Unit 1in Park City, Utah, to restore, rehabilitate, replace, and/or acquire the equivalent of natural resource injured from releases of hazardous substances.  The No Action proposal was selected over other considered alternatives because a habitat equivalency analysis conducted by the Service for the site determined that no additional restoration projects are necessary to restore the site to either baseline trust natural resource conditions or to compensate further for lost trust natural resource uses and services.  We anticipate that on-site resources will recover over time through enhanced habitat availability due to restoration projects already completed by the Responsible Party and through natural attenuation of residual environmental contamination.  Implementation of our proposal will have no significant environmental, social, and economic impacts since it is the No Action alternative. 

We would like to know what you think about the Finding of No Significant Impact (FONSI).  The FONSI is available for public review and comment.  All comments received within 30 days following April 4, 2013, the date of this notice, will be considered. 

The RP/EA can be reviewed by clicking the hyperlink above or by contacting the Utah Ecological Services Field Office at 801-975-3330.  Comments on the FONSI may be sent to Larry Crist by mail at U.S. Fish and Wildlife Service, 2369 W. Orton Circle, Suite 50, West Valley City, UT 84119, or by fax to 801-975-3331.
