The recent move by Prime Minister Mark Carney to expedite a new oil export pipeline to the West Coast is heightening the pressure on Ottawa to address a long-standing environmental issue in the oilsands of Northern Alberta – the management of tailings ponds.
Oil production in the region is expected to increase, with the Alberta government aiming to double crude output. However, the industry has faced restrictions on water release since the inception of the first oilsands mine six decades ago. Consequently, vast tailings ponds in the area hold years of industrial mining wastewater that is hazardous to wildlife and concerning for residents due to potential health and environmental risks.
Efforts to deter birds and wildlife from the ponds include continuous use of air cannons and scarecrows. The scale of the issue is immense, equivalent to 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 risen by 50% from 2014 to 2024, as reported by the Alberta Energy Regulator. The industry is advocating for regulations that permit the treatment and controlled release of the fluid, while some Indigenous leaders are urging a slowdown in oilsands production until the matter is adequately addressed.
Alberta Environment Minister Grant Hunter emphasized the need for scientific validation and regulations to enable the industry to responsibly manage the tailings ponds. The government plans to outline water quality standards by year-end, although final decisions rest with Ottawa given federal jurisdiction over waterways.
Companies assert their capacity to treat tailings water effectively but seek clear regulatory guidance on quality standards. They argue that without addressing the tailings ponds, comprehensive land reclamation cannot be achieved.
Discussions on potential treat-and-release practices have stirred concerns among Indigenous communities, particularly in Fort Chipewyan. Some residents fear the impact on water quality and environment, leading to protests against industry demonstrations.
Alternative approaches to treat-and-release are being explored, with Tũ Nipi Water Solutions receiving funding for research into non-release solutions. There are apprehensions among Indigenous groups regarding the health and environmental implications of releasing treated water into water bodies.
The industry has invested in testing various technologies for wastewater treatment, collaborating with researchers on water and tailings projects. Ottawa’s stance remains undisclosed, with the federal government yet to outline a timeline for regulatory decisions on tailings management.
