The Canadian Nuclear Safety Commission (CNSC) has accepted the final Environmental Impact Statement (EIS) for the proposed Rook l Project, submitted by NexGen Energy Ltd. (NexGen). This acceptance follows a comprehensive EIS technical review process by the Federal Indigenous Review Team (FIRT), including consultations with Indigenous Nations and communities and members of the public. CNSC staff will now proceed with the preparation of the Canadian Environmental Assessment Act, 2012 Environmental Assessment (EA) Report, which will be made available, along with a Commission Member Document, for review by Indigenous Nations and communities and the public prior to a public Commission hearing.

The following documents have now been posted:

• Letter: CNSC to NexGen – Rook l Project - Acceptance of the Final EIS and Supporting Documents
• Rook l: Final environmental Impact Statement
• NexGen Responses to Public and Indigenous Nations and communities comments on the draft environmental impact statement 

With these conclusions, along with the sufficient licence application, CNSC staff will notify CNSC Commission Registrar of this acceptance, who will proceed with scheduling public hearing dates. Further details regarding how to participate will be provided once the Commission Secretariat has announced the hearing dates. In early February, notifications will be sent to Indigenous Nations and communities with detailed next steps in the consultation process.
