Draft supplemental EA for Deroin Bend chute repairs available for review

Published July 7, 2015

OMAHA, NE – A draft supplemental environmental assessment for repairs to Deroin Bend chute in Holt County, Missouri between Missouri River miles 519 to 517 is currently available for public review. The draft supplemental EA evaluates the environmental impacts of repairing damage to the chute that occurred during the 2011 Missouri River flood. 

Repairs are needed to prevent continued erosion of the chute caused by the 2011 Missouri River Flood and maintain the chute's function as shallow water habitat. Proposed repairs include the installation of six new dike structures designed to slow water velocities, accrete sediments, and help maintain the chute’s designed alignment. The riverward side of a notch through an existing rock structure within the chute would be lowered to prevent the chute from migrating outside its designed alignment.

The public is encouraged to provide comments on the draft supplemental environmental assessment, which is available for viewing at: http://www.nwo.usace.army.mil/Missions/CivilWorks/Planning/ProjectReports.aspx. Comments can be mailed to: U.S. Army Corps of Engineers, Omaha District; CENWO-PM-AC; ATTN: Matt Vandenberg, Deroin Bend SEA; 1616 Capitol Avenue; Omaha, NE 68102-4901. Comments can also be emailed to: cenwo-planning@usace.army.mil. Comments must be postmarked or received no later than August 3, 2015.

This draft supplemental EA is consistent with the National Environmental Policy Act of 1969, as amended, the Council on Environmental Quality’s  regulations for implementing NEPA (40 CFR 1500-1508), the Corps’ regulations for implementing NEPA (33 CFR 325 and Engineering Regulation 200-2-2) and other applicable environmental laws and regulations.
