The National Post reports in its Wednesday, July 27, edition that Husky Energy knew something might be wrong with one of its oil pipelines about 14 hours before it told the Saskatchewan government of a leak that has since forced communities along the North Saskatchewan river to seek alternative drinking water. A Canadian Press dispatch to the Post reports that in an update posted to its website Tuesday, the company said its monitoring detected "pressure anomalies" last Wednesday at 8 p.m. as several segments of the pipeline were being returned to service. Such a thing is common when pipelines are started up, the company said. Husky said it immediately began reviewing information. Crews were sent to check the pipeline but they did not find a leak. The company said it began to shut down the pipeline as a precaution 6 a.m. Thursday. That morning, a sheen was spotted on the river and Husky's emergency response plan kicked into gear. Cleanup crews were sent to the spill site near Maidstone, Sask. The Saskatchewan government got word of the spill at about 10:30 a.m. that day. The pipeline runs from Husky's heavy oil operations to its facilities in Lloydminster.
