Pendleton, OR -

A company that plans to ship coal down the Columbia River has signed a letter of intent with Tidewater Barge Lines of Vancouver, Wash., for transportation service.

The East Oregonian reports (http://bit.ly/1g1ZwAx) Tidewater would operate the tugs and barges needed to move the coal 218 miles from the Port of Morrow at Boardman to a terminal at the Port of St. Helens at Clatskanie.

Ambre Energy has applied for permits from the Army Corps of Engineers, Oregon Department of State Lands and the Department of Environmental Quality.

The barge project is one of three proposals to ship coal from Montana and Wyoming to Asia. The others would use trains to deliver coal to terminals at Longview, Wash., and Cherry Point near Bellingham, Wash.
