  •  It's an eighty year old pipe (13+ / 0-)

    Ten years ago they were running crude through a seventy year old pipe. Back twenty years ago they were running crude through a sixty year old pipe. The Keystone Pipeline is estimated to have a life of 50 years, with between 11 and 91 leaks discovered and plugged during that 50 year period. The number of leaks is based on new assumptions about the construction and maintanance of the pipeline. 80 years ago the assumption about leaks would have been ten times higher.

    So they have been running through seriously old pipe for at least thirty years.

    Federal Government regulations seem to assume that a pipe will last as long as it's economically feasible to maintain it. They also assume a certain number of leaks are inevitable, and require biweekly inspections to catch those inevitable leaks. If the pipe is buried, some of those inevitable small leaks might not be detected during the first inspection after the leak started. Actual reported spills are over 500 per year.
