The recent move by Prime Minister Mark Carney to expedite a new oil export pipeline to the West Coast is ramping up pressure on Ottawa to address a long-standing environmental concern in Northern Alberta’s oilsands – the management of tailings ponds.
Oil production in the region is on the rise, with the Alberta government aiming to double crude production. However, the industry has been prohibited from discharging water since the inception of the first oilsands mine nearly six decades ago. Consequently, the area is dotted with extensive tailings ponds brimming with decades of industrial mining wastewater, posing a threat to wildlife and the environment.
To deter birds and wildlife, air cannons and scarecrows are deployed around the ponds. The scale of the issue is massive, with the volume of tailings fluid expanding by 50% from 2014 to 2024, amounting to as much as 600,000 Olympic-sized swimming pools.
As the capacity of tailings ponds nears its limit, industry players are urging for regulations permitting the treatment and discharge of the fluid. On the other hand, Indigenous leaders are advocating for a slowdown in oilsands production until the matter is appropriately resolved.
Alberta Environment Minister Grant Hunter emphasized the need for scientific validation and regulatory frameworks to facilitate the treatment and release of tailings water. The government plans to unveil water quality standards by year-end, although final decisions rest with Ottawa due to federal jurisdiction over waterways.
Companies assert their capability to treat tailings water effectively and seek clarity on water quality standards to advance cleanup efforts. Suncor Energy’s Vice President, Claire Greenwood, stressed the importance of treating and releasing water for large-scale reclamation, with a vision to transform tailings ponds into reclaimed sites.
The prospect of releasing treated water into the Athabasca River has sparked concerns among Indigenous leaders and communities, with some expressing skepticism about the treat-and-release approach. Chief Melody Lepine of the Mikisew Cree First Nation voiced apprehension over the provincial government’s push for treat-and-release, underscoring the need for community confidence in the technology’s safety.
Tũ Nipi Water Solutions, an Indigenous-led company, aims to explore alternatives to treat-and-release, emphasizing the need for sustainable water management practices. The debate surrounding this issue is intense, with stakeholders pushing for responsible and environmentally friendly solutions.
The federal government’s stance on tailings ponds remains ambiguous, with no clear timeline for regulatory decisions. Industry efforts to develop effective treatment technologies and collaborations with research institutions signal a commitment to addressing water contamination challenges in the oilsands region.
