The Proponent's submission explicitly states that the impact assessment will only include a 'conceptual' analysis for post-closure safety, with detailed design deferred to later CNSC licensing stages. For Melgund Township, which relies entirely on local aquifers for water, accepting a 'conceptual' model for the longest phase of the project (post-closure) is an unacceptable risk. Deferring detailed safety validation until after the IAA approval removes the community's leverage to ensure the permanent protection of the local watershed. We must demand that the 'integrated manner' of assessment brings the rigorous scientific certainty of the CNSC process forward into the public IAA phase to guarantee long-term environmental safety before the project is authorized.
