Professori, I read that link you posted and it stated that the rupture was caused by a construction crew and their backhoe. How is this in any way the fault of the pipeline company? Of course, the first thing the crew is going to say is the pipe wasn't marked properly. CYA. I have pipelines running through my neighborhood and I am not worried. However, if a crew broke one digging my first response would not be to blame the pipeline owner.
