Mr. Speaker, in 2021, Environment and Climate Change Canada, ECCC, and nine indigenous communities established the Crown-indigenous working group for potential oil sands mining effluent regulations, CIWG. The CIWG is exploring options to manage the buildup of oil sands mine water in tailings ponds located in the Athabasca oil sands region. One of the options under consideration is regulations that, if developed, would place strict protective conditions on the release of treated effluent to the Athabasca River. Any such regulations would be developed with protective standards reflecting available scientific information and indigenous knowledge. The key deliverables of the CIWG will include recommendations on the path forward for managing the buildup of oil sands mine water.
Last fall, the public and stakeholders were invited to provide input on an introductory paper, found at https://www.canada.ca/en/environment-climate-change/services/managing-pollution/sources-industry/mining-effluent/oil-sands.html, which included an update on the work completed by the CIWG to date, an overview of the collaborative process established through the CIWG and an opportunity for early feedback. The release of the introductory paper was accompanied by targeted engagement sessions with stakeholders and interested parties, including provincial and territorial governments, oil sands mine operators, environmental non-governmental organizations, academia and indigenous communities not included on the CIWG. In May 2024, ECCC published a “what we heard” report, found at https://www.canada.ca/en/environment-climate-change/services/managing-pollution/sources-industry/mining-effluent/oil-sands/summary-report-introduction-crown-indigenous-working-group.html, summarizing input received on the introductory paper. ECCC plans to publish a discussion paper, accompanied by further stakeholder engagement, by the end of 2024.
ECCC has been meeting regularly with the CIWG since the group was established in 2021 and leverages subgroups that have been established. The current focus of the CIWG is publishing a discussion paper by the end of 2024, completing an assessment of available treatment technologies, developing aquatic toxicity and monitoring requirements and developing an approach for incorporating indigenous knowledge.
