Interested parties are hereby notified that the U.S. Army Corps of Engineers, Portland District (USACE) is seeking public comment on the Federal Navigation Channel Operations and Maintenance Dredging and Dredged Material Placement draft Environmental Assessment (EA) for Skamokawa Creek, Westport Slough, Old Mouth Cowlitz River, and Upstream Entrance to Oregon Slough. The draft EA was prepared in accordance with the National Environmental Policy Act (NEPA), the Council on Environmental Quality’s NEPA regulations (40 C.F.R. parts 1500–1508), and the Corps’ NEPA regulations (33 C.F.R. part 230).
USACE is proposing to perform operations and maintenance dredging and dredge material placement for four federal navigation channels at Skamokawa Creek, Westport Slough, Old Mouth Cowlitz River, and Upstream Entrance to Oregon Slough. The dredged material would be placed in the Corps’ existing network of upland placement sites and in the Columbia River from River Mile 3 through 145 where water is 20 feet deep or greater.
