It's a public port; they don't need a written agreement for occasional use, do they? It's only recently that they've started to receive multiple, large volume shipments. Seems to me that they could have been operating on the basis of just making arrangements as they needed to before they started getting continuous, large-scale shipments. I bet they tested the waters at Kalama. Better to figure it out now so the shipments don't get backed up as shipping ramps up. More 'ducks n a row.'
Remember this?
