As I explained earlier, on the crude oil side of the business, the oil price is set on a world market basis and it's come back to this. Those facilities will come back out of the net back that would go back to the producer. It's a transportation cost that will be built into the facilities.
As we're building new facilities, of course it makes sense to use the state-of-the-art ones that are there, and as we're ordering new tank cars, they're being built to the new standard as well. All of the new ones that are coming on for this growth that we anticipate are going to be meeting that new standard. It's really a question of how quickly we can transition the older ones out. Our risk-based approach does allow that to be done in a very safe manner as quickly as we can.
