We have received information. It was the report of some staining on the ground that caused us to heighten our oversight of what was happening in this area and to compel Imperial to take extensive actions to identify the source of this.
I think it's important that as we talk about these things, we remember there were two incidents at Kearl. One was an incident involving tailing seepage.

Containment ponds are intended to hold water that has run off or snowmelt from across the mine site to ensure that they are in a good state before they're released from the mine site.
