The west coast has always had quite a robust joint review process. Many of the guidelines, practices, and procedures that we have in place are of long standing. Most predate my time.
What we do on a constant basis is revisit those practices and procedures, look at what we are presently doing today, and re-evaluate. That's what occurred with the Haro Strait-Boundary Pass change. That had been a practice since 1989, I believe, but with the implementation of the additional tanker traffic that we expect, there was a decision made jointly—by “jointly”, I mean ourselves, the pilots, and the industry—to relook at it. We did some fast-time simulations and made our decisions based on that, with industry's full support.
