I can only speak to three of those companies, and they're not the only operators within the oil sands, nor are they engaged in that portion of the industry to the south of their lease areas, which are in steam injection processes of removal, without excavation for the deeper deposits. But you have challenges, in that with the additional expansions and new investors in the area, they will have an initial draw from the Athabasca, while at the same time you have expansion and traditional users who are continually pushing the envelope toward a lower draw. When they put water both in the settling ponds and in the tailings area, it's to allow the fine silt to settle, and it takes time for it to settle out of the process. To the extent that there is an immiscible component of petroleum in the water, it takes time for that to settle. All those companies are investing at their research centres in Edmonton on improving those processes to increase the runaround and to reduce the draw on the Athabasca.
But there is a dynamic going on there, where some companies are ahead of others in their process, in that 90% recycle. In some parts of the mining industry, for example, at Raglan in northern Quebec, there's a different style of mining; it's 100% recycle. And that's the goal we're shooting for collectively as an industry--100% recycle. There's a very minimal draw in the first instance, but then we just keep recycling that water through our process, and ultimately, when it does get released back into the environment, it's released to the metal mining effluent regulation standards, or it is released to water quality standards, whichever is the better standard.
