The proposed Keystone XL pipeline running from Alberta's tar sands south to Nebraska and Texas continues to stay in the public eye.
But this week it was reported that over the past few months, a million liters (quarter million gallons) of oil from several pipelines have spilled in Alberta. Canada's The Star reported on Wednesday that cleanup crews are working to prevent contamination from the three major oil spills:
The latest spill occurred earlier this week in northeastern Alberta near the town of Elk Point, where Enbridge confirmed a spill of about 230,000 liters through its pumping station on the Athabasca pipeline. The biggest incident was earlier this month near Red Deer and Sundre in central Alberta, where 475,000 liters of oil from Plains Midstream Canada leaked, some of it spilling into the Red Deer River.
This is not the first time the Canadian tar sands giant, Enbridge, has been involved with an oil spill. In July 2010 one of its pipelines ruptured in Marshall, Michigan and spilled an estimated 819,000 gallons.
Even proponents of the Keystone XL pipeline see these incidences as worrisome, and confidence in the tar sands extraction and transportation throughout Canada has clearly been shaken.
