No. We have a principle that if you can do things better--it's called ALARA, as low as reasonably achievable. We try to continuously improve. For example, in uranium mines in operation, every time we can find a way of doing things better, we will look at that.
So yes, when the original environmental assessment was given, that was the plan at the time. All of a sudden when new technology comes in, or a proponent comes in with a new idea, we look at it. We would not approve it if we didn't think it was a good idea.
