Comment on the Draft Integrated Tailored Impact Statement Guidelines for the Deep Geological Repository for Canada’s Used Nuclear Fuel, April 10, 2026

The April 10 draft package makes an important correction to NWMO’s earlier effort to treat off-site transportation as external to the project. The draft integrated tailored impact statement guidelines now require that “transportation of both nuclear and non-nuclear materials outside of the project site” be included among the project components and activities considered in the Impact Statement, and they state that project-related transportation has the potential to result in adverse effects within areas of federal jurisdiction. That change should be retained in the final guidelines.

What the package does not yet do is say clearly enough what follows from that change.
