At the end of 2021, utilities reported 116 open leaks and 88 repaired leaks in FRAMINGHAM. These leaks were responsible for 59.3 metric tons of methane emissions, equivalent to 5,101 metric tons of carbon dioxide, or $60,384 of leaked gas (at residential rate).

WE ARE WORKING TO OBTAN MORE UP TO DATE INFO ON THIS MATTER.

Leaks are graded by the utilities to indicate how potentially hazardous they are, ranging from Grade 1 to Grade 3 SEI, defined as follows:

Grade 1 leaks are hazardous and must be repaired immediately. This includes leaks in or near a contained space, such as a building or manhole, where the gas could build up enough to potentially explode.
Grade 2 leaks are non-hazardous, but could become hazardous in the near future. They must be repaired within a year.
Grade 3 leaks are non-hazardous and are expected to remain non-hazardous. Grade 3 leaks initially designated on or after 1/1/2018 are required to be repaired or eliminated within 8 years.
Grade 3 SEI are grade 3 leaks larger than 2000 square feet in rectangular extent – these are leaks of significant environmental impact, or SEI’s. They are approximately the largest 7% yet contribute approximately 50% of all leak emissions. They are required to be repaired in 1-3 years. HEET is working to improve utility adoption of the leak extent method to better identify SEIs in the field.

On the map below, at the end of 2021, the green leaks were repaired, and the red ones were still unrepaired.

They just installed a brand new gas line to a house on my street. As in, the house did not have a gas line before. Kind of amazing there are this many leaks in town, and they spend the time installing a new one.
