The recent move by Prime Minister Mark Carney to accelerate a new oil export pipeline to the West Coast is heightening the pressure on Ottawa to make a decision on a long-standing environmental issue surrounding the oilsands in Northern Alberta – the management of tailings ponds.
As oil production in the region is poised to increase, the Alberta government aims to double crude production. However, since the establishment of the first oilsands mine around six decades ago, the industry has been prohibited from discharging any water. Consequently, extensive tailings ponds in the area are filled with decades of industrial mining wastewater, which is toxic and poses a threat to wildlife and residents concerned about health effects and environmental impact.
To deter birds and wildlife from the ponds, air cannons operate constantly, alongside scarecrows dressed in work attire. The scale of the problem is immense, equivalent to about 600,000 Olympic-sized swimming pools or covering the area of the Island of Montreal under three meters of water.
The volume of tailings fluid has surged by 50% over a ten-year period from 2014 to 2024, as reported by the Alberta Energy Regulator. With the ponds reaching capacity, the industry is advocating for regulations allowing the treatment and release of the fluid. However, some Indigenous leaders are urging a slowdown in oilsands production until the issue is adequately addressed.
Alberta’s Environment Minister Grant Hunter emphasized the need for science-backed solutions to address the challenge instead of maintaining the status quo. He highlighted that industry cannot be expected to double production without the necessary tools for proper treatment and release.
By the year’s end, the Alberta government plans to outline the water quality standards for potential release. Companies assert they possess the technology and expertise for treating tailings water but require clear regulations on water quality standards. They stress the importance of addressing the tailings ponds to facilitate large-scale reclamation efforts.
If approved, treated water would be discharged into the Athabasca River, raising concerns among some Indigenous leaders and communities. Chief Melody Lepine of the Mikisew Cree First Nation expressed skepticism about the treat-and-release approach, emphasizing the need for assurances that the technology will not harm human health or the environment.
Industry players have been investing in technology and water monitoring programs while exploring various treatment methods for tailings water. Pressure is mounting on Ottawa to act, with calls for stringent regulations and alternative approaches to treat-and-release. The federal government’s stance on the matter remains undisclosed, with no specific timeline provided for decision-making.
In conclusion, the debate surrounding the treatment and release of tailings water from the oilsands continues, with stakeholders advocating for sustainable solutions that prioritize environmental protection and public health.
