I have lived and worked in the heart of the Oil & Gas fields of Alberta my entire life so to me "another pipeline" is just that "another pipeline". There is alway's going to be risk involved. The goal is to mitigate those risks to the point of the lowest acceptable level. When that point has been reached the project is then reviewed again and the decision made to
move forward or cancel the project. Most people have know idea how
many safeguards are put in place to reduce operational risk in a
transmission line of this magnitude. But there is still going to be a remote chance that an incident may occur. As the maps in the link show, at this point in human evolution pipelines are a fact of life and will remain so until technology provides us with a safer more cost efficient means moving gas and liquid products. Just a side note, the maps only denote main arteries, there is thousands of miles of laterals just to get the product to the main pipelines. Just a little food for thought.
