Gas Infrastructure & Pipeline Leaks

The pipeline and natural gas industries are aiming to build new and larger gas infrastructure projects in Massachusetts. 

We oppose these expansions for many reasons. Read below to learn more and get involved.

RoxburyPipelineProtestUnfortunately, we use quite a bit of natural gas in Massachusetts today (all "natural" gas is now extracted through fracking). More than half of our electricity is generated from gas-fired electricity plants, and many building and home heating systems rely on it currently as well. We know this does not have to be the case. Our own state's Comprehensive Energy Plan shows that we can protect Massachusetts electricity customers from price volatility, reduce risks of disaster, and reduce air and climate pollution by aggressively converting to electric-source heating systems powered by greater amounts of renewable energy. We can end our reliance on this dirty and dangerous fossil fuel very soon, if we act now.

We Don't Need More Gas Infrastructure

Pipeline proponents are saying that new gas infrastructure, including pipelines, compressor stations, and metering stations, is necessary to meet increased demand in Massachusetts and keep electricity costs low. This is simply not true. Existing gas pipelines are on average almost half empty. The pipelines are used to capacity only a handful of days a year, during cold winter blasts, and even then, they may not actually be full but simply fully contracted - meaning utilities have paid for capacity but then not used it. There are less expensive and significantly less disruptive ways to meet occasional demand spikes.

If all the proposed new infrastructure projects were to be built, they would increase the pipeline capacity in Massachusetts by 73 percent. Given our local needs and everything we know about the needs of the planet, there is no justification for that increase. The pipelines are being built to take fracked gas to facilities in the US and Canada for export. According to the Congressional Research Service, "a significant rise in U.S. natural gas exports would likely put upwards pressure on domestic prices" - this is the opposite of what the utilities and pipeline companies are telling us.

New Gas Infrastructure Is Not a Good Investment

There have even been industry attempts to force utility ratepayers (homeowners, renters, businesses, institutions, municipalities - all of us who pay utility bills) to finance the construction of new pipelines and compressor and metering stations, shouldering the financial risks of financing while the industry garners any profits. Fortunately in August 2016 the Massachusetts Supreme Judicial Court ruled unanimously that such a scheme is illegal.

Billions spent on new fossil fossil fuel infrastructure could be spent instead on the renewable energy future that we need to move toward expeditiously. An energy system based on renewable sources  will serve us in many ways: It will help stave off the worse impacts of climate change; it will help our MA economy; it will improve the air we all breathe and water we all drink; and it will give us a future free of the price volatility of fossil fuels. Taking dollars away from renewables will lock us into exporting our energy dollars. According to the MA Dept of Energy Resources, of the $22 billion we spend annually on energy in MA, $18 billion leaves the Commonwealth. We need to spend that money here, on energy efficiency, energy conservation, renewables, and fixing the old, leaking pipelines we already have.

Pipelines Are Dangerous

In addition to all the above, gas infrastructure is dangerous. They transport a gas that is highly flammable and subject to explosion. The tragic 2018 Merrimack Valley explosions demonstrated that all too well. An entirely avoidable over-pressurization event destroyed dozens of homes, left thousands of families without heat or power as winter approached, and caused the death of an 18-year old man.

SierraClubDeliversBoHLetterstoGovBakerDespite this disaster in our own backyard, high-pressure pipelines are still being proposed in high-density residential areas, a dangerous mix. In December 2018 a new gas safety law was introduced to require “all natural gas work that might pose a material risk to the public be reviewed and approved by a certified professional engineer.”

This is the time to move quickly toward a new, renewable energy future, not spend billions on the old way - the volatile, toxic, expensive, monopolistic, fossilized way.

Contact Your Local Board of Health

Over 90 Boards of Health across Massachusetts sent letters to Governor Baker with deep concerns over the health impacts of pipelines, urging comprehensive health impact assessments before approvals of any new projects. The number of Boards of Health continues to grow with the help of citizen activists like you. For help contacting your local Board of Health and urging them to join this initiative, click here to email Michele.

Plugging Gas Leaks

Massachusetts has one of the nation’s oldest natural gas infrastructural systems, and it is showing its age.  Old cast iron and steel pipes are especially prone to leaks.  In December 2018, the Department of Public Utilities released their fourth annual report on gas leaks (they have only been required to do so since the passing of 2014 law). This DPU report provides data for the year 2017, and found:

  • 48% of recorded leaks in 2017 were new leaks

  • 78% of new leaks in 2017 were hazardous (Grade 1 or Grade 2)

  • 16,778 leaks remained at the end of 2017

  • The cost to repair all remaining leaks is $70 million

Gas Leak Statistics

Leaks Threaten Safety, Health, and the Environment

GasPipelinesWhen natural gas is burned, it produces carbon dioxide, but the gas itself is primarily methane  which is the second-largest contributor to global warming after carbon dioxide.  When gas leaks methane into the atmosphere, the climate impact is even worse because methane captures 84 times as much heat in the atmosphere as carbon dioxide over a 20-year period. Massachusetts is legally required to reduce climate pollutants by 25 percent by 2020 and 80 percent by 2050. Leaking pipelines undermine our efforts to reach these goals.

  • According to a 2016 study by Boston University, a handful of super-emitters--about 7% of all leaks-- are responsible for half of the leaked gas.  Repairing these huge leaks can sharply reduce the state’s methane emissions and save ratepayers real money.

  • Natural gas (all natural gas is now extracted through fracking) is harmful to vegetation, kills trees, and forms ozone which affects human health and aggravates allergies and asthma.

  • Replacing old pipe with new reduces operations and maintenance expenses. From a CLF report: "According to the filings of natural gas companies with replacement programs in place, for every mile of leak-prone pipe that they replace, they can reduce repair costs, defined as operations and maintenance expense, by up to $1,761 for bare steel and up to $2,188 for cast iron. Over the course of a year that can add up to $7.5 million in avoided operations and maintenance expenses if that pipeline is replaced with new pipe."
