With regard to the government's development of proposed regulations governing the treat-and-release of oil sands process-affected water into the Athabasca River: (a) as part of the consultation process, will free, prior, and informed consent be sought on any regulation governing the management of tailings in the oil sands region; (b) is a decision-making matrix being developed to clearly articulate how feedback from rights holders and other stakeholders is being considered in the finalization of a regulatory framework for tailings management; (c) what assessments have been completed since January 2021 regarding the potential human health, ecological risks and cumulative environmental effects associated with the release of treated tailings into the Athabasca River, and, what are the details, including (i) the number and type of risk assessments commissioned, (ii) the cumulative effects scenarios modelled and what contaminants were analyzed, (iii) whether these assessments incorporated Indigenous knowledge, Indigenous-identified receptors, or community-identified health concerns; (d) what companies or industry associations have engaged directly with Environment and Climate Change Canada on the proposed treatment and release of tailings, and has a formalized process been established between industry and the government to discuss tailings management issues, and, if so, how many meetings have taken place, and when did these start; (e) how does the government ensure that the development of treat-and-release regulations complies with federal commitments to address environmental racism, including (i) which provisions of the National Strategy to Address Environmental Racism and Environmental Justice have been applied, (ii) how disproportionate impacts on downstream First Nations have been evaluated, (iii) how the results of these evaluations will influence regulatory design; (f) how will the development of a regulatory framework align with the government’s obligations under the United Nations Declaration on the Rights of Indigenous Peoples Act, specifically regarding (i) the right to free, prior, and informed consent, (ii) Indigenous peoples’ rights to traditional lands and waters, (iii) protection from discriminatory environmental decision-making; and (g) broken down by operator, what tailings ponds or process-affected water facilities are being considered for possible treat-and-release under the proposed regulation, and, for each facility, (i) what volumes of process-affected water are projected for potential release, (ii) what contaminants of concern and associated levels are expected to remain post-treatment, (iii) how have long-term cumulative loadings to the Peace, Athabasca, and Slave watersheds been assessed and characterized?
