The first report from the mines chief auditor confirms British Columbia has one of the best tailings storage facility (TSF) regulatory frameworks in the world. The revisions made to TSF regulations had positive impacts on their management and operation and helped ensure mining activities remain safe for workers, communities and the environment.

The chief auditor’s report, Audit of Code Requirements for Tailings Storage Facilities, concludes that the changes implemented in 2016 to the Health, Safety and Reclamation Code for Mines in British Columbia are consistent with established industry best practices, are clear and enforceable, and have a high level of compliance from industry.

The chief auditor provided seven recommendations to ensure regulations and oversight continue to improve and offer strong environmental protection. The B.C. Ministry of Energy, Mines and Low Carbon Innovation has accepted all seven recommendations and developed a new action plan to support implementation.

“This first audit allows us to assess how our mining regulations and standards work, identifying what we can build and improve upon to ensure safety for people, communities and the environment,” said Bruce Ralston, B.C.’s Minister of Energy, Mines and Low Carbon Innovation. “We are committed to implementing all seven recommendations put forward by the chief auditor and will continue our work to build a world-leading regulatory framework for TSFs here in B.C.”

The seven recommendations are summarized as follows:

  1. Resolve inconsistencies and overlap in TSF regulation between the code and the Dam Safety Regulation under the Water Sustainability Act.
  2. Develop a plan for determining when and how the regulatory framework for tailings storage facilities will be updated to reflect evolving best practices.
  3. Clarify ambiguous language in the code pertaining to TSFs.
  4. Revise the code guidance document to be consistent with the code.
  5. Ensure ministry staff and regulated parties have a common understanding of the ministry’s approach to compliance verification and enforcement of the TSF regulatory framework.
  6. Develop plans to ensure the workload of geotechnical inspectors is prioritized effectively.
  7. Ensure compliance data for tailings storage facilities are entered, used and managed consistently among ministry staff.

“The 2016 revision of the code related to TSFs was selected as one of our first audits due to the importance of this topic and the high level of interest from Indigenous communities, the public and industry following the breach of the TSF at Mount Polley,” said Andrew Rollo, chief auditor. “I want to thank the audit team for their dedication to producing a high-quality report and recommendations that I believe will contribute to the continuous improvement of TSF oversight in British Columbia.”

The chief auditor is an independent statutory role established in August 2020 through amendments to the Mines Act. The chief auditor is tasked with conducting audits to evaluate the effectiveness of the regulatory framework for mining in B.C. and is supported in this work by the Mine Audits Unit. The ministry created the audit function as part of a comprehensive response to concerns identified by the auditor general in 2016.
