At least 39 homes have been damaged by natural gas line explosions across three communities in the north Boston area. The problem appears be over-pressurization of the gas lines from Columbia Gas. State police are telling anyone with gas service from Columbia Gas to evacuate. In addition, electricity has been cut to all building in Lowell, Andover, and North Andover.

Emergency crews are responding to what they believe is a series of gas explosions and fires that damaged at least 39 homes and across three communities north of Boston and which prompted massive evacuations.

At least one home in Lawrence was leveled by an explosion as a result of a problem with gas lines that feed homes in Lawrence, Andover and North Andover.

State police said anyone with gas service from Columbia gas should immediately evacuate their homes. State police said gas lines are being depressurized, but that the process takes time.

State police reported that electricity was being cut to all buildings in Lawrence, Andover and North Andover.

Yeah, yesterday was quite the news day while we were all watching the hurricane. Manafort, the gas thing, and the solar observatory thing that is so weird that I put it in Off the Beaten Track. (I like Sam's mercury bearing idea... the telescope is mounted on just about the biggest one anywhere.)

The gas thing is rather unsettling. Houses just started blowing up and/or catching fire. Lots of them. All over three towns in greater suburban Boston. Yes, they told anyone with that gas company to de-ass the area.

Conspiracy folk think Russian hackers did it, of course. The rest of us are going "WTF?"

so they say it was over pressurization does that mean they just kept upping the pressure to make up for leaky rotting pipes instead of replacing or repairing them? and if so did the increased pressure cause them to deteriorate further and faster?

Natural gas explosions: Boston-area gas pipes among oldest and leakiest in US

Quote:
.........In its most recent filing with federal pipeline safety regulators, Columbia Gas reported 471 miles of cast-iron and wrought-iron gas distribution lines – the kind of old gas pipe that the government and safety experts have been pushing utilities to replace for more than a decade.

Fire investigators and state emergency management officials said Thursday night that the devastating chain of fires might have been caused by over-pressurization in the gas lines. Federal, state and local investigations continue today. Columbia Gas, which serves 300,000 customers in the Merrimack Valley, has not commented on the potential cause.

One man was killed and at least 10 other people were injured in the fires.

Whatever the cause, the area's bare-metal gas mains have been a well-documented safety concern for government regulators and the gas company itself for years, federal and state records show.

.The old cast-iron pipes prevalent in the Boston-area systems – some installed well more than 50 years ago – are susceptible to rust and corrosion, which can lead to leaks and explosions.

The old pipes have been blamed by fire investigators and the National Transportation Safety Board in many deadly gas explosion disasters in recent years.

The Pipeline and Hazardous Materials Safety Administration has been pushing gas utilities for more than a decade to replace aging pipes with more resilient materials such as plastic, but it's not required by law........

Class-action lawsuit filed

Quote:

.........Senators Warren and Markey demanding answers
While the fires have been put out and the gas in the affected homes has been turned off, Senators representing the displaced residents are still looking for answers as to why these fires happened in the first place.

In a letter addressed to the presidents of both Columbia Gas of Massachusetts and its parent company, NiSource, Massachusetts Sens. Elizabeth Warren and Ed Markey, citing briefings from federal officials, claim the pressure in the Columbia Gas system reached readings of 12 times higher than the system was intended to hold, and that the fires were likely linked to this over-pressurization.

Representatives for Columbia Gas and NiSource have not yet responded to CNN's requests for comment.

Both Warren and Markey are demanding answers regarding a detected pressure increase in a pipeline in Lawrence, Massachusetts, and the companies' response plan when last Thursday's incident was reported. They are also seeking copies of the companies' plans for any equipment upgrades, Columbia Gas' Integrity Management Plan, and its current emergency response plan for the affected area.

The senators also sent a letter to the Pipeline and Hazardous Materials Safety Administration (PHMSA) at the US Department of Transportation, requesting additional information on regulations "intended to avoid incidents like this, or which direct the response to them." Among their questions: did PHMSA review Columbia Gas' Integrity Management and emergency response plans -- and did they find any part of those plans to be deficient?............

They were not trying to increase the pressure in the lines, they were retiring a section of old cast iron main. When that line was shut down, a regulator control line was still connected, so it opened up go feed a line it thought was needing gas, even though it had been retired.

This is gonna be a mess for a while, but this is what happens when you leave old gas infrastructure in the ground.

No. Companies didn't want to spend the money 30 years ago to upgrade. These companies are made up of all sorts of people, some are R some are D, they are all greedy.

No, corporations are greedy no matter who is president. What happens is that they are far more likely to get their way when the Republicans are in.

I don't see this as a political issue, I have been involved in this industry for a few years now, it is simple greed. Dont think for a second these places donate only to one side of the aisle.

^ I'm inclined to agree. They'll buy anyone that they can.

Did they really shut off all the meters on that system?

They will have to zowie. Once the gas was shut off at the mains, all meters must be shut off. They will then repressurize, purge, and turn each meter back on and complete a safety inspection and relight pilot lights.

Its expensive.

Yep

All the dirt sitting on the bottom of the lines that got into the orifices will need to be cleaned out.

A regulator control line was left hooked up to a section of main that was being retired. When they started purging the retired main to get the gas out, the control line opened up thinking that the main needed more gas. Looks to be a case of human error, I dont know if the utility or a contractor was responsible. There have been one or two.news articles that had a pretty detailed description of the event, which really surprised me, usually it takes months to get the big picture.

These older systems dont have as many safety features, such as relief valves and regulators at the house.
