I think the NEB basically agreed with us that the CNSC relief valve requirement was a key component of safe offshore drilling. The really critical component in the Arctic is this. If you're drilling, the principle is that you need to stop drilling operations early enough in the season so that it will still be possible, in the event of a blowout at the tail end of your season, to drill a relief well before the season ends.
The consequences of having a blowout that isn't capped, that isn't stopped in the season, is that once the ice forms in the fall it's absolutely impossible to do any operations for seven to nine months, depending on how far north you are. During that time there would be oil spilling out without any mitigation measures being possible.
So not only would there be up to seven months of activity, but that oil, then, would also be coming up to the surface and fusing with the newly formed sea ice. That changes the whole trajectory of spilled oil, because the oil becomes layered in kind of a sandwich of the newly formed ice, and then it's distributed as the ice is distributed and released when the ice melts. It creates much more complex recovery and mitigation obstacles.
