I would think they would have a very difficult time if the agency could demonstrate that in fact there are other technologies and that they could change the way they're operating. Let them make their case, but the agency has that same opportunity to argue that case, so it's something the agency will follow up on.
We heard about when shunting is happening. They can locate the shunting operations. That's been done in the past. Somebody mentioned earlier about the agency looking at the latest state-of-the-art technology, state-of-the-art-practices. That's exactly the flexibility we want to provide to the agency, because what is operational today will change in a year from now.
There are new standards for locomotives coming out. There are Green Goat locomotives, which are yard locomotives. They're much quieter. They're more fuel efficient. Maybe the agency can go in and say that rather than using your regular locomotive, use a Green Goat locomotive. It's more efficient, makes less noise, and does the same kind of activity.
Let's preserve that flexibility for the agency.
