WALLA WALLA—The U.S. Army Corps of Engineers, Walla Walla District, invites the public’s comments on the draft Finding of No Significant Impact (FONSI) and the Lower Snake River Channel Maintenance Immediate Need Dredging for Commercial Navigation Environmental Assessment (EA).

The Corps proposes to restore the lower Snake River federal navigation channel by removing sediment below the Ice Harbor Dam navigation lock near Pasco, Wash., and near the confluence of the lower Snake and Clearwater rivers near Clarkston, Wash., and Lewiston, Idaho.

The proposed dredging and disposal would occur during the in-water work window from December 15, 2022, through March 1, 2023. The dredged material would be disposed of in the lower Snake River at Bishop Bar, River Mile 118 in Washington State.

The 30-day review and comment period began on July 18 and will conclude on August 18. Comments may be submitted via email at NEPANWW@usace.army.mil, inserting “LSR 2022 Dredging” in the subject line, online at http://www.nww.usace.army.mil/EnvironmentalComplianceComment/, or by mail to
