I'll start and then again defer to those who are directly involved in this activity.
Certainly in the working groups that were established by Minister Raitt back in mid-November, there were three: one was to look into the DOT-111 tank cars; one was to look into emergency response capability; and one was actually to look into the whole issue of the testing and classification of crude.
We, as associations—probably more from the CAPP side than us on the fuel side—have been directly involved and significantly involved in that ongoing activity with respect to ensuring that the testing and classification of crude is done appropriately and adequately to address the levels of safety that are required.
With that, I'll defer to Dave. He's the one who's probably been most directly involved in that.
