The environmental impact statement is a rigorous assessment of all of the potential impacts of the project, but also the benefits of the project from a socio-economic standpoint. It looks at all of the aspects of the environment, biological, physical, the human environment, and, as I mentioned, the socio-economic impacts, and also the safety and security aspects of the project. All of those are dealt with in the environmental impact statement.
The various components of an environmental impact statement are prepared by independent consultants, independent firms that specialize in those kinds of assessments. They will assess the valued environmental components, for example, and will make a determination of significance of impact, with the consideration of anything that TransCanada in this case would be proposing to do to mitigate any of those impacts.
Ultimately, the National Energy Board, through its staff and members, will review that environmental impact statement. It will be made available publicly, and will certainly be the subject of review as well during the public hearing process.
