In a move to expedite a new oil export pipeline to the West Coast, Prime Minister Mark Carney’s recent decision has heightened the urgency for Ottawa to address a longstanding environmental concern surrounding the oilsands in Northern Alberta – the management of tailings ponds.
The Alberta government aims to double crude production as oil output in the region is projected to increase. However, the industry has been prohibited from discharging water for about 60 years since the inception of the first oilsands mine. Consequently, large tailings ponds in the area are filled with decades of industrial mining wastewater, posing a toxic threat to wildlife and raising health and environmental concerns among residents.
To deter birds and other wildlife from the water, air cannons operate continuously around the tailings ponds, alongside numerous scarecrows dressed in work attire. The scale of the issue is immense, with the volume of tailings fluid expanding by 50% over a decade from 2014 to 2024, according to the Alberta Energy Regulator.
With existing tailings ponds reaching capacity, the industry is advocating for government regulations to permit the treatment and release of the fluid. Meanwhile, some Indigenous leaders are urging a slowdown in oilsands production until the matter is adequately addressed.
Alberta’s Environment Minister, Grant Hunter, emphasized the need for scientific validation to enable the industry to manage the issue effectively, rather than maintaining the status quo. The provincial government plans to outline water quality standards for release by year-end, awaiting federal endorsement or modifications.
Companies assert their capability to treat tailings water but stress the necessity of clear regulatory guidelines. They argue that resolving the tailings ponds issue is crucial for comprehensive land reclamation efforts. Suncor Energy’s Vice President, Claire Greenwood, emphasized the importance of treatment and release for large-scale reclamation projects.
If authorized, the treated water would be channeled into the Athabasca River, passing through Indigenous communities before reaching the Arctic Ocean. While some support the treat-and-release approach, Indigenous leaders like Chief Melody Lepine of Mikisew Cree First Nation express concerns about potential environmental impacts and community well-being.
Indigenous-led initiatives like Tũ Nipi Water Solutions are exploring alternative methods to treat tailings to alleviate concerns about water contamination. CEO Ron Quintal advocates for technology that facilitates water reusability to address generational trauma associated with water pollution.
Pressure mounts on Ottawa to act, with industry players investing in wastewater treatment technologies and research collaborations with universities. The federal government’s stance remains ambiguous, with Natural Resources Minister Tim Hodgson alluding to forthcoming regulations without a definitive timeline, prompting calls for more transparency and action from various stakeholders.
