Cumulative impact assessment is not a particularly easy thing to undertake. Most of the EIA's cumulative impact implications are all done based on modelling activity. You develop a model of what the potential cumulative impact would be. All models are wrong, but some are useful. What those models do is predict where you might look for an effect and what the effect would be. It's something where fellows like Jim and I would go out and try to do some work in the environment to see if the model predictions are in fact correct and whether or not we can pick up cumulative impacts.
When I say cumulative impacts, please don't assume that I'm talking strictly about the potential activities of the currently operational oil sands leases and their potential impact on the river system.
