Background Information

The Panel considers the supporting information and substantiating documentation to be an integral part of its report that is necessary for a proper understanding of its findings.

There are multiple parties involved in various investigations of Mount Polley Tailings Storage Facility (TSF) failure. The Panel must ensure that the conduct of the inquiry does not in any way impede or conflict with any other ongoing investigation or proceeding related to this matter. Specifically, the Panel’s review must not in any way impede investigations conducted by Mines Inspectors, Conservations Officers or other regulatory agencies and any related proceedings. Further, all disclosures of the Panel must be compliant with the privacy protection provisions of the Freedom of Information and Protection of Privacy Act (FIPPA).

The B.C. Ministry of Energy and Mines and Ministry of Environment, Conservation Officer Services, have directed the Panel to withhold some of the documents, and redact portions of other documents, so that the Panel’s inquiry does not compromise any other investigations and to ensure it is in compliance with the privacy protection provisions of FIPPA (see Appendix A). The redaction of personal information was completed by Shared Services BC. As a result, these documents, which may have been cited in this report, are not available at this time. See Appendix B for more information on the provision of Supporting Information.
