Sure. I understand the confusion, because it's very confusing how these various pieces of legislation work.
We do our navigational assessment and provide it as part of the environmental assessment. The impact a project has upon navigation is one of the components of an environmental assessment, but we're only one of many components that is evaluated under that environmental assessment.
If in the overall picture of the environmental assessment, from all the information gathered on all of those components, the decision is made that the project proposes no substantive impact to the environment and therefore a recommendation is positive on an environmental assessment, at that point, if we wish, we can issue an approval document.
