Columbia River System Operations

Columbia River System Operations

In accordance with the National Environmental Policy Act, the U.S. Army Corps of Engineers, Bureau of Reclamation, and Bonneville Power Administration, referred to as the Action Agencies, intend to prepare an environmental impact statement (EIS) on the Columbia River System operations and configurations for 14 federal projects in the interior Columbia Basin.

In this Columbia River System Operations EIS, the three agencies will present a reasonable range of alternatives for long-term system operations and evaluate the potential environmental and socioeconomic impacts on flood risk management, irrigation, power generation, navigation, fish and wildlife, cultural resources and recreation. The Action Agencies will serve as joint-lead agencies in developing the EIS.

Comments received during the public scoping period (September 30, 2016-February 7, 2017) provides anyone who is interested an opportunity to help the agencies identify issues and concerns that could be analyzed in the EIS.
