First of all, it's important to go back to the fact that there were two separate incidents at Kearl, the first one being seepage from the tailings pond, the second one being an overflow of a containment pond.
As we reported openly and transparently—and you can find information on our website, which I spoke about in April—the containment pond is a pond that collects snow melt and runoff and other water from across a mine site. It is important that water not be allowed to just run off the mine site, so it is put into containment ponds. It is tested and monitored to ensure among other things total suspended solids are settled to an acceptable level that meets the expectation.
It was that pond, the second incident, that happened just at the time the emergency protection order was being prepared, that overflowed. It overflowed water that, while it may have some level of contaminants in it, is predominantly runoff as I indicated. It was -30 at the time of that event, and most of that water was captured in the containment system and/or froze in close proximity to the edge of the mine site.
As such, Imperial was able to recover the vast majority of that water and return it back onto the mine site into the proper ponds.
