Those are key. Our experience is that the in situ projects have fewer environmental effects. In fact, they very often don't trigger the federal environmental assessment, because no federal decisions related to those projects are required. But in the case of oil sands mines, very often they have important effects on surface water, water courses, fish habitat, and so forth.
If there is a trigger with an in situ project, it would typically be conducted at the screening level, as opposed to having a public review through a panel review. So the environmental assessment process in the case of a screening would be a little more straightforward than in the case of a review panel.
