Columbia Gas of Massachusetts (NiSource) continues to try and recover (physically and reputationally) from a series of explosions in its local delivery pipelines north of Boston in mid-September (see Local NatGas Pipes Explode Near Boston Killing 1, Injuring 25). The explosions and resulting fires tragically killed one teenager and injured 25 others. It left some 8,600 households and businesses without natural gas–for months. In early October, Columbia said it would replace all ~48 miles of natural gas mains, and all 6,100 affected service lines, by Nov. 19 (see Columbia’s Master Plan to Restore Gas Service in Mass. by Nov 19). While the main lines will be done early, by tomorrow in fact, Columbia, in something of a public relations disaster, is pushing back the date of finishing the service lines by about a month, into December. Meanwhile, the family of the teenager who was killed is preparing a wrongful death lawsuit.

To Columbia’s credit, 80% of the mains are already done, and over half of the service lines.

The National Transportation Safety Board (NTSB) has just released a preliminary report on what caused a series of explosions and fires in a natural gas pipeline system 25 miles northwest of Boston in mid-September (see Local NatGas Pipes Explode Near Boston Killing 1, Injuring 25). The NTSB confirmed that the cause was overpressurized pipes due to workers capping off an old pipeline that contained sensors telling the system to pump more gas than needed. The question becomes, Who’s at fault? NTSB says the fault lies clearly Columbia Gas themselves.

We continue to track the story we first brought you on Monday of this week, that late last week there was a chain-reaction of explosions in local natural gas delivery pipelines about 25 miles north of Boston (see Local NatGas Pipes Explode Near Boston Killing 1, Injuring 25). The explosions and resulting fires tragically killed one teenager and injured 25 others. Local officials ordered some 8,600 residents and businesses in the three communities to evacuate–until Sunday. A major incident. The ramifications of this situation will go on for years. Although it’s still early in the investigation process, the cause of the explosions appears to be a combination of old/decaying pipes with too much pressure flowing through them. According to an NTSB spokesman, the early indicators are that a pressure sensor is the cause (see Pressure in Exploded Massachusetts Pipes 12X More than Normal). Here’s what *may have* happened: A pressure sensor that controls how much gas is pumped through local pipelines was attached to a portion of a pipeline that was capped at both ends and closed off. The sensor detected little-to-no pressure, so it signaled the system to keep increasing the pressure, to flow more gas. The pressure eventually reached 12 times what it should have been, and the older cast iron and steel pipelines couldn’t take it, resulting in explosions and fires. The question turns to who capped off the pipeline with the sensors? Who was working on pipelines in that community on that day? A Boston TV station tracked down the who…

You don’t often think of the safety of the pipeline network that delivers natural gas to your home or business because it’s so rare there are any problems with it. When’s the last time you heard about a local delivery pipeline exploding? Last Thursday a major incident occurred 25 miles northwest of Boston when delivery pipelines owned by Columbia Gas (NiSource) in three communities–Andover, North Andover and Lawrence–exploded and caught fire at “more than 60 locations.” The explosions and resulting fires tragically killed one teenager and injured some 25 others. Local officials ordered over 8,000 residents and businesses in the three communities to evacuate, turning off electric and gas. Each house and business was then tested before turning electricity back on (gas is still off). Residents were finally able to return to their homes on Sunday. It’s a huge incident, a big, fat, stinking mess. Folks waited in lines for hours at claims centers to file requests for reimbursement for hotels and expenses after being displaced from their homes–only to have the claims centers close because Columbia couldn’t handle the numbers. On Friday, Massachusetts Gov. Charlie Baker declared a state of emergency in the three communities. Later in the day on Friday, he invoked a little-used (and little-known) provision in the state constitution that allowed him to take management of the crisis away from Columbia/NiSource, giving management of the crisis to a competitor, Eversource. Although it’s still early in the investigation process, the cause of the explosions appears to be a combination of old/decaying pipes with too much pressure flowing through them. Attention has turned to pressure sensors along the pipelines. Yesterday Columbia/NiSource announced it will replace all 48 miles of the cast iron and bare steel pipeline system in that area. Meanwhile, the affected 8,000+ residents and businesses will not have gas service restored “for weeks” at a minimum…
