We're not in the mining sector, which is the historical oil sands. There are a large number of regulations with respect to utilization of water from the Athabasca River.
What I know is that there are limitations with respect to low-flow periods. There are a number of areas with very specific regulations.
On the in situ side, where we are, there really is a prohibition, for commercial purposes, on drawing surface water. We are really going below to non-potable sources so that we don't have the impacts, which people are seeking to mitigate, with respect to withdrawals from the Athabasca.
