On December 11, 2012, a portion of the Columbia Gas Transmission pipeline (owned by Nisource) exploded near Sissonville, WV, 10 miles north of Charleston. The resulting fire burned for more than an hour and shut down a portion of nearby Interstate 77 for days (see Columbia NatGas Pipeline Explodes Near Charleston, WV). It’s been a long time coming, but on Monday the National Transportation Safety Board (NTSB), that did a full investigation of the explosion, turned in their final report. It was pretty damning for NiSource/Columbia. The conclusions of the investigators are that a) the pipe had corroded in that section–a long time ago, and b) Columbia hadn’t inspected that section of pipeline since (unbelievably) 1988. In other words, it was an accident waiting to happen.
Below we have the press release from the NTSB with their high level findings, then the full 32-page report released Monday, and finally, the lame response issued by NiSource/Columbia “thanking” the NTSB for just ripping them a new one…
