Just to be clear, the tanker exclusion zone relates to ships carrying crude oil from Alaska to the state of Washington. Today it does not preclude tankers from going in and out of our west coast. In fact, they do so today and have done so for decades. So there's no impact on that.
It does increase traffic, but as I mentioned, we anticipate 220 tanker calls a year. That is just over one a day in terms of both in and out, but that's not a significant increase on the activity you'd see in the Prince Rupert area. It is more than what's on the Douglas Channel today, but again it is restricted to one a day.
