Mill Creek Project O&M SEIS

Collapse All Expand All

The U.S. Army Corps of Engineers - Walla Walla District (Corps) plans to prepare a Supplemental Environmental Impact Statement (SEIS), in compliance with the National Environmental Policy Act (NEPA), for the continued operation and maintenance (O&M) of the federally managed portion of the Mill Creek Flood Control Project at Walla Walla, Washington, and implementation of actions to avoid or minimize potential effects to Endangered Species Act (ESA) -- listed fish and/or associated critical habitat. 

The SEIS will supplement the June 1975, Mill Creek Project, Walla Walla, Washington, Final Environmental Impact Statement (FEIS), prepared by the Corps for the operation, maintenance, and improvement of the federally managed portion of the Project. The SEIS will identify and evaluate current O&M actions that may not have been adequately addressed in the 1975 FEIS or have been implemented since completion of the 1975 FEIS, and actions that are proposed for the future. It will also identify and evaluate operational and structural measures the Corps has proposed to improve fish passage through the Mill Creek Project. 

Public scoping for this effort will take place from May 12 through June 12, 2017.

 

The Corps invites comments from the public regarding The Corps invites Federal, state, and local agencies, affected Native American tribes, and other interested organizations and people to participate in the development of the SEIS. The Corps invites interested parties to provide specific comments on issues and alternatives the Corps should evaluate in the SEIS related to the continued O&M of the Mill Creek Project.

An open-house-style public scoping meeting is also scheduled for Wednesday, May 24, 2017, from 4 p.m. to 7 p.m. in the Walla Walla Airport Terminal Building Conference Room, located at 45 Terminal Loop Road in Walla Walla, Washington.
