The uninterrupted passage of Canadian mining waste into Montana’s transboundary waterways continues to gain urgency as proposals for new mines in British Columbia file into the provincial government’s regulatory queue, prompting U.S. Sen. Jon Tester to ramp up pressure on the State Department for intervention, a move the Montana Democrat says is years overdue.
Alberta promises close watch on new mines but cuts oversight of coal-polluted rivers
Alberta government documents show repeated cuts to environmental monitoring despite contaminants in some waterways that exceed thresholds that are supposed to trigger increased scrutiny. The province's 2019 five-year monitoring plan shows stations on two rivers and a creek polluted with selenium from coal mines were mothballed. That was despite more than two decades of readings that Alberta Environment guidelines suggest should have led to closer attention.
