According to an article I just read in the Etoile, it would be destined to european markets. The CEO of the port Rayburn Doucett gives an interview and talks about other opportunities and projects who will soon take place or that are in the works at the port without mentionning what they are.
I think that the port will really be the savior for the region surrounding it, for those who have never seen it, I encourage you to look at the website of the port just to give and idea of the size and of all the land available for developpment around it. Even with this company buying 250 acres, there is still tons of land available at the port for developpment and expansion.
In the last few years, the port has doubled in size and every year there is a new infrastructure projects. For those who will be looking at the site, just note that the new permanent weight station and expantion to the bulk storage facility at the MD young terminal where not yet built at the time they updated the picture of the port.
