We work very closely with our sister association down south, the American Chemistry Council, and with the STB, the transportation board in the States, to ensure that if we're not on the same page yet, at least we're all in the same book.
When we're talking about the thickness of tank car standards, or which screws go where, and what the shell might look like, if they're not harmonized, it means the tank car will get to the border and then just be turned away, so what we're looking at doing, and what we thoroughly recommend, is keeping pace with the U.S., quite frankly. I know it's not a very exciting recommendation, but ultimately it's how things are most going to move quickly from producers through to shippers through to customers at the end of the market.
