Reclamation Managing Water in the West: Echo Dam, Weber River Project: Summit County, Utah, Safety of Dams Modification, Environmental Assessment and Finding of No Significant Impact

摘要

The Bureau of Reclamation (Reclamation) proposes to undertake construction activity at Echo Dam to perform seismic upgrades to the dam and spillway. Echo Dam, part of the Weber River Project, is located about 6 miles north of Coalville, Utah, at the junction of Interstates 80 and 84. The proposed construction activity would require Congressional authorization under the Safety of Dams Act of 1978, Public Law 95-978, as amended. Reclamation has prepared this environmental assessment (EA) to comply with procedural requirements of the National Environmental Policy Act of 1969 (NEPA), Public Law 91-90, as amended, and the Council on Environmental Quality and Department of the Interior regulations implementing NEPA. This EA analyzes the potential impacts of the proposed action. As required by the NEPA implementing regulations, if potentially significant impacts to the human environment are identified, an environmental impact statement will be prepared. If no significant impacts are identified, Reclamation will issue a Finding of No Significant Impact (FONSI). This EA describes the environmental effects of addressing the safety deficiencies of Echo Dam.
