Belmont Citizen-Herald: March 24, 2016
If you ask me, the whole situation stinks. At the end of 2015, there were 74 leaks in the natural gas pipes serving Belmont residents. Two of those leaks, one on Fletcher Road and the other on Marsh Street, were first reported to National Grid in the summer of 1996.
Now, I realize that not all gas leaks are equal. State law categorizes such leaks into three “classes.” Class 1 leaks are those considered to be an “existing or probable hazard to person or property.” As the Home Energy Efficiency Team, a Massachusetts environmental organization, notes, “leaks that are not considered a ‘probable future hazard’ don’t have to be fixed, ever.”
National Grid finds itself spending more of its time and money meeting crises than getting ahead of the problem. On March 1st of this year, National Grid filed its annual report on gas leaks with the state Department of Public Utilities. Two-thirds of the 61 leaks National Grid repaired in Belmont in 2015 were Class 1 leaks. Nearly all of these leaks the company repaired, including all 40 of the hazardous ones, it didn’t even know existed going into the year. In contrast, 52 of the continuing leaks National Grid deemed to be non-hazardous remained unaddressed in 2015, simply going into the company’s data base of things to track and report. In addition, 22 new “non-hazardous” leaks were identified in Belmont in 2015.
The town of Belmont has little or no control over how quickly, if at all, National Grid fixes gas leaks throughout the community. In a meeting with representatives of Belmont’s Mothers Out Front organization in January, Belmont’s Department of Public Works staff said that the town has nothing to do with when or whether or in what priority gas leaks are fixed by National Grid. DPW’s sole role is to issue “street opening permits” when someone digs in a public street. Their job is to ensure that the road is in the same condition after the digging as it was before the digging. In addition, when the town excavates a street, the underlying pipelines are fixed or replaced.
Quite aside from existing leaks, one problem facing Belmont is the prevalence of “leak prone” pipelines. More than half of the 85 miles of natural gas pipeline underlying Belmont’s streets are prone to leaks, either due to the age of the pipe or due to the material from which the pipes are made.
Apart from whether a gas leak is immediately dangerous to the public, gas leaks harm the environment. According to HEET, “natural gas is primarily made of methane, a remarkably potent greenhouse gas that is 85 times more destructive to the climate than carbon dioxide over its first 20 years.” HEET says that the greenhouse gas emissions from gas leaks in Massachusetts are “roughly equivalent to the emissions of all the state’s businesses and factories combined. It is easier to fix a majority of these leaks than to persuade most factories and businesses to stop emitting.”
“To add insult to injury,” HEET says, “the utilities don’t pay for the wasted gas, but instead pass the cost onto ratepayers by factoring the lost gas into the price we pay. . .”
HEET is now working with the Metropolitan Area Planning Council, the regional planning commission of which Belmont is a part, to identify “best practices” of local governments to help control the region’s natural gas leaks. So far, Belmont has declined to participate in that MAPC effort. Belmont residents should be concerned, if not because of the immediate local dangers, because of the broader environmental consequences of the failure to repair.
