Environmental Impact Statement


The Environmental Assessment (EA) for the Rook I Project (Project) evaluates the potential environmental effects associated with all Project activities during all phases.

An Environmental Impact Statement (EIS), which contains the Project EA, has been submitted to regulators and represents a culmination of more than 8 years of detailed data collection and analysis incorporating all Project technical, environmental, and social aspects. The EIS is currently in the provincial and federal review process, with provincial technical review comments and federal technical and public review comments having been received by NexGen.

NexGen has been working with Indigenous Groups throughout the EA process to ensure Indigenous and Local Knowledge was incorporated into the EIS.

  • Individual EIS sections providing:
    • Project, regulatory, Indigenous Group, and stakeholder context;
    • Technical methods and assessments;
    • Information about Project resilience;
    • EA summaries including residual Project and cumulative effects, mitigation, monitoring, and follow-up programs; and
