I want to be very clear that all of the points on the current safety regime are being covered.
What we're suggesting is there need to be enhancements to that to make sure we prevent any future incidents and can get to the maximum amount of safety that can be there. That's not to say there's nothing there now. Clearly, the testing is there now, the regulations on where the locations can be are there right now, and the safety of transportation, whether that be by rail or pipeline, are all in place right now through the operations and through the regulations that are there.
