The port initiated the subsidies to offset the cost of truck or rail transportation while the river system is closed for three months of repairs, said a port representative.

Under the program, each shipper receives a payment per container, regardless of size. If the container originates from the Port of Lewiston, the allowance is $400. For those from the Port of Boardman or the Port of Umatilla, the allowance is $250 per container.
