TransCanada proposed a fourth phase for the pipeline as far back as 2008. This is known as the Keystone XL project and it is Keystone XL that is causing controversy. The XL project will provide a second route through the North-West of America from the Western Canadian Sedimentary Basin in Alberta, Canada. It will supplement the existing capacity provided by the Keystone pipeline.
Would the Keystone Pipeline be above ground or below ground? Most of it would be under ground. Some areas, like near pump stations, maintenance and inspection ports, and at locations where communities will tolerate it, it may be above ground since freezing is not an issue with the contents of the pipeline. Being below ground protects the pipeline from destruction by the Leftist anti-energy nut-jobs.
