Heavy rain in southern Alberta is probably the cause of a ruptured natural gas pipeline and threatens flooding in the city of Calgary, home to Canada’s oil industry.
Calgary has imposed a state of emergency with residents in low-lying areas near the Elbow River being evacuated, the city’s website said. The town of High River, 48 kilometers (30 miles) south of Calgary, experienced “extremely dangerous and rapid flooding,” while further west near the town of Turner Valley a pipeline owned by Legacy Oil & Gas Inc. leaked hydrogen sulfide, the Alberta Emergency Management Agency said on its website.
Emergency responders evacuated 39 people from Turner Valley after the natural gas leak, Alberta Energy Regulator spokeswoman Cara Tobin said in a phone interview from Calgary. The cause of the leak hasn’t been determined, but there’s a “high probability” that it was caused by the flood, she said.
Residents in the area near the pipeline were being evacuated by emergency responders due to the risk of exposure to toxic gas from the leak, according to the agency. No dangerous levels of hydrogen sulfide were detected by air monitoring equipment, Tobin said.
Canadian broadcaster CBC reported that about half of High River, with a population of about 13,000 people, had been flooded.
