This environmental effects assessment, like the effects assessment provided in the 2007 EAC Application, is a sustainability-based environmental assessment that considers five interconnected and interdependent “pillars” which are environment, economy, social, heritage, and health. The following sections of the Application for an EAC Amendment provide a description of the proposed amendments and how they differ from the certified Project. This report also includes an assessment of valued components during the construction, operations and decommissioning phases of the Project. Potential environmental effects of the Project were identified in the 2007 EAC Application. The effects assessment in this application identifies new potential effects that were not identified on the certified route. Potential effects that are unchanged from the 2007 EAC Application are not identified. A full assessment for the new temporary facility is provided.
