We're in the middle of a 15-year plan. We are still working our way through that. We want to use the very best technology and new ideas. We are very open to new ideas. We're putting money into science, technology, and research right now, as you would know.
I just want to pick up another point about the FCSAP, the federal contaminated site assessment plan. At the early stages, we are finding about one in two of these assessments, or 53%, technically resulted in the site being found to be contaminated. More recently, it is only about one in five sites. Is that an indicator that we maybe took on the worst sites first? In fact, is it not as bad in terms of numbers and achievability of this plan as it might indicate?
