That is a very controversial question. In some of the more recent working groups that I actually worked very closely on, we just went through that very debate. We went to the experts in our region. So we went to the regional infrastructure working group, where all the industry sits, and they provided all their best estimates of what their various footprints are. So they know what their reclamation would be, what their footprints are for clearing, what their water withdrawals are. So industry actually fits there and makes other stakeholders aware of what their footprints will be.
On that particular issue, we had discussions under the sustainable ecosystem working group, which is working on the landscape terrestrial management system for terrestrial resources. I think we finally decided on 4 million.
