It would be huge, I can tell you that. There is a per barrel rate that I don't remember. Right away I could just multiply this for you, but I can find out. I'm trying hard to get a study going to do just that, because it's important to have that information.
Regarding your earlier question about sinking or not sinking, the Kalamazoo spill is diluted bitumen and it was so difficult to clean. This is what some of the officials of the U.S. EPA say. No one expected sunken oil to be so difficult to clean up. This is a quote I took from officials when it happened. It's a big issue.
