Alternatively, it must be demonstrated that the import of materials is a non-substantial departure from approval. Where a decision to approve the receipt, storage, treatment/processing, and use of imported materials on a mine site is required, and where the decision may impact Aboriginal Interests, consultation with impacted Indigenous nations will be required.
