The worst thing about diluted bitumen is that it captures the worst of all fuels. It captures the acutely volatile and lethal components. It captures the long-term persistent components. We don't have to look very far to see what cold water crude oil spills look like on this coast, and the impacts they've had on populations elsewhere, specifically Alaska.
We've looked at these kinds of things on our coast. We look at what makes populations vulnerable, small populations, large aggregations of animals that are together in certain spaces or certain times. All it takes is one poorly timed spill to have repercussions that last for decades, if not longer.
