Apparently, some refining is being done in Canada, and it is already being transported by truck and train. However, the oil people want to transport more, faster. The initial extraction apparently leaves a peanut butter consistency mass with high sulfur (acid), other toxins, much quartz sand, etc. It is then mixed with other chemicals to allow it to be pushed through the pipeline under high pressure. It is highly corrosive and abrasive, far more so than other forms of raw crude, and has a much higher pipeline break rate. Having broken, especially into waterways, it is many times more expensive to clean up. This is the problem with the Kalamazoo River break. It will be used for the export market from Houston, not our US consumption. Let them build it to the Pacific if they are selling it to China.
and did notice the word if in the sentence, almost didn't LOL for my vision sometimes eludes me. Here is my reasoning ... china is busying themselves to corner the market of oil and have their currency replace the dollar as the standard. May you live in interesting times, comes from a Chinese proverb. Living in interesting times could be a synonym for may you live in dangerous times, where we presently together coexist.
