Thank you for your question.
What we're talking about here, in this bill, is the exclusion for toxic inhalation goods, which includes ammonia. There's no safety reason for this. We're not sure what that exclusion was done for. Other dangerous goods are not excluded, so there can't be a safety reason for this. Obviously, our goods, when they're dangerous, we have to look after. We have to steward them. We work very closely with the railways and everyone else, including first responders, in doing that. But these provisions that we're talking about, interswitching, are economic provisions. They're not safety provisions.
I don't know if that gets to your question.
