It should be built. There is more risk and cost to the environment with the present set up. We have tankers coming in full and leaving empty. There is less environmental risk with the pipeline bringing oil from the west. Then the tankers leave full - and can be stalled if the weather is bad or if there are other issues that would cause a hazardous situation. There are pipelines all over the place now -you just don't see them since they were built so long ago. Rail cars are mush more hazardous. It is a proven fact, both statistically and anecdotally.
