LEWISTON, Idaho -

Federal officials are seeking comments from the public on a plan to dredge sediment from the port in Lewiston.

The U.S. Army Corps of Engineers is proposing to remove thousands of cubic yards of sediment from the river along the Port of Lewiston. The plan also involves dredging sediment at the nearby Port of Clarkston in Washington.

The Lewiston Tribune reports the plan calls for removal of 20,000 cubic yards of sediment from both ports.

The federal agency is seeking comments as it prepares a final draft of the environmental impact statement. The soonest dredging could begin is a year from now, but that timeline hinges on federal approval of a plan for managing the sediment.

Environmentalists opposed to dredging the ports and navigation channel have threated to sue.
