Accidents can happen at the best run industrial facilities. That's just a fact of life. But with the pipeline and it's history a couple of factors should always be in the back of your mind. First the pipeline has long since passed it's engineered life expectancy. If nothing else it can no longer safely carry the volume of oil it once did. Secondly all of the major players allowed maintenance to fall off for years until there were massive problems, spills and the accompanying massive fines leveled against them They were all in fact put on probation over this. Since they are not raking in the massive bucks they were when oil was over a 100 bucks a barrel it is fair to wonder whether maintenance is again being short changed. I don't claim this is what happened here but is was fires at several facilities that foreshadowed the last round of really serious problems. Hope this is not the case.
