There's nothing in Part 20 that provides for a transfer of responsibilities to the National Energy Board. The National Energy Board's responsibility for environmental assessments will remain essentially the same, even if Part 20 is adopted. Part 20 states that the responsibilities of the Canadian Environmental Assessment Agency are being consolidated by requiring that more in-depth studies be conducted, except for projects regulated by the National Energy Board or by the Canadian Nuclear Safety Commission. Those two quasi-judicial agencies are already responsible for the environmental assessment of the projects they regulate. We're maintaining the status quo for their projects.
