A recent string of leaks from tailings ponds at oil sands operations upstream has once again drawn attention to the profound transformation Canada’s largest industry has had on the region – and the distrust that comes with it. In May, Calgary-based Imperial Oil notified Alberta’s energy regulator it had discovered discoloured water near its Kearl oil sands project. The regulator soon concluded the water had come from tailings ponds where the company stored the toxic sludge-like byproducts of bitumen mining. Environmental samples showed high levels of several toxic contaminants, including arsenic, iron, sulphate and hydrocarbon – all of which exceeded provincial guidelines.
Canada's Indigenous communities call for regulatory overhaul after tailings leak
Indigenous communities in Canada's oil sands region on Monday called for Alberta's energy regulator to be disbanded and replaced following a months-long toxic tailings seepage from Imperial Oil's Kearl oil sands mine. Community representatives were testifying to a parliamentary committee in Ottawa about the impact of the leak and ongoing concerns about oil sands tailings management.
Alberta premier says Imperial Oil should have disclosed tailings pond spills
Alberta's energy regulator may have ignored provincial law by not publicly disclosing that waste from a large oilsands tailings pond was escaping containment and seeping into groundwater, says a lawyer. Drew Yewchuk of the University of Calgary's Public Interest Law Clinic is asking the province's information and privacy commissioner to investigate how and why the Alberta Energy Regulator chose not to release information on the leak at Imperial Oil's Kearl mine, despite direction in provincial law to do so.
Contaminant from coal mines already high in some Alberta rivers: unreported data
The province's plan for large-scale expansion of the industry is fueling widespread criticism that includes concerns over selenium pollution. The data shows that same contaminant has been found for years at high levels downstream of three mines and never publicly reported. The findings raise questions about Alberta Environment, said a former senior official who has seen the data. "There were lots of [selenium] numbers and it was consistently above the water quality guidelines and in many cases way higher," said Bill Donahue, the department's one-time executive director of science. "Why did Alberta Environment sit on these data for easily the last 10 to 15 years?"
