Comments Invited on Lewiston and Clarkston Dredging Plans

Regulatory officials of the Walla Walla and Seattle Districts of the U.S. Army Corps of Engineers invite public comments on two lower Snake River system ports’ applications to dredge port berthing areas and dispose of dredged material.

Written comments are due to the Corps no later than Dec. 18, 2013, regarding Port of Lewiston, Idaho, and/or Port of Clarkston, Wash., applications to perform port dredging work in conjunction with the Corps’ proposed “Immediate Need Action” of dredging detailed in its Lower Snake River Programmatic Sediment Management Plan (PSMP) Draft Environmental Impact Statement (DEIS).

Each separate port permit application is for:

1) a Department of the Army Permit, and

2) a Washington Department of Ecology Water Quality Certification.

Corps Regulatory officials are reviewing the proposed dredging and disposal work in accordance with Section 404 of the Clean Water Act (CWA), Section 10 of the Rivers and Harbors Act, and other applicable laws and policies.

Walla Walla District is responsible for reviewing proposed work in the waters of the United States in the state of Idaho, while Seattle District is responsible for reviewing proposed in-water work in Washington state.

The Washington Department of Ecology will also be considering comments submitted directly to Ecology as part of its review for a water quality certification under Section 401 of the Clean Water Act.
