Suncor is an example. Judy alluded to the $1.2 billion commitment they have made in a technology referred to as TRO, tailings reduction operation. That is one example.
Syncrude has made an initial commitment to commercially implement a centrifuging technology, using mechanical means to de-water the oil sands tailings.
Canadian Natural Resources Limited is working with Du Pont to develop a technology relying on a polymer to help flocculate and settle out the tailings faster.
There are additional technologies at the prototype scale. Something we call accelerated de-watering has been piloted on a small scale. Syncrude is embarking on an initiative to pilot this on a much larger scale.
I could go on. I recognize we're short on time, but there are numerous technologies being implemented, both commercially and piloted at a large scale, at the various operations in Fort McMurray.
