Yes, those considerations are present.
I would also like to point out that some of those considerations are being worked through right now by the review of Arctic drilling by the National Energy Board. They are the people who are responsible for ensuring that the technical operational aspects of the actual drilling meet necessary standards. As you may be aware, they are actively involved in a full review right now, having recently had a week-long consultation session in Inuvik, and are intending to report before Christmas, as I understand it. They would be addressing the specific parameters that would be deemed safe and appropriate for Arctic drilling.
