DEQ moves to allow river dredging to be placed on west Hayden Island

Columbia River sediment deemed to have contaminants below levels of concern

The Oregon Department of Environmental Quality is set to approve the Port of Portland's request to place 20,000 to 40,000 cubic yards of dredged material from the Columbia River onto west Hayden Island.

DEQ, which is still taking public comment on the request, will hold an informational meeting about the proposal at 6:30 p.m. Monday, Oct. 24, at the Park Room, 1275 Jantzen Beach Center, in Portland.

The port is dredging the river near Terminal T-6 to maintain safe navigation of the Columbia River. DEQ reviewed lab analytical data for the sediment and determined that contaminants are below the levels of concern for people and animals, based on current and proposed uses of the property.
