The concern is that the NEB certificate contained a number of conditions, one of which was a sunset date that indicated we must commence construction no later than December 31, 2015. We have about three years of detailed engineering work and permitting, as I mentioned—about 7,000 site-specific permits, etc.—that we need to undertake before we commence construction. That's about three years' worth of work.
