Methane Gas Leaks
METHANE GAS (OFTEN KNOWN AS NATURAL GAS) has heated the homes of many Americans for over a century – and for over a century, it has been prone to leaks, putting communities and the environment in danger. With growing awareness of the impact of methane leaks on the climate, and with growing availability of safer alternatives, it is clear that gas has no place in a modern clean energy network.
Gas leaks and pipeline incidents are common and put public health and safety at risk.
• In 2010, a gas terminal failure in San Bruno, California, caused an explosion on the scale of a magnitude 1.1 earthquake. Eight people were killed and 58 were injured.
The event led to the creation of mandatory gas safety programs around the country.
• In 2018, high-pressure gas was accidentally released into low-pressure gas distribution lines in the Merrimack Valley of Massachusetts, starting more than 80 fires in three towns.
An 18-year-old was killed, and thousands of people went without gas for months. In March 2022, a four-story apartment building in Silver Spring, Maryland, was destroyed in an explosion caused by a leak coming from a cut gas line. In total, 14 people were hospitalized and over 200 were displaced.
A gas pipeline incident occurs somewhere in the U.S. approximately every 40 hours. From 2010 through nearly the end of 2021, almost 2,600 pipeline incidents related to the release of gas occurred in the United
States that were serious enough to be reported to the federal government, 328 of which resulted in explosions. Those explosions and fires killed 122 people and injured.
The amount of gas leaking to the environment is far greater than captured in federal leak reporting or emissions estimates from the Environmental Protection Agency (EPA)
A 2020 study, for example, estimated that there are more than a half million leaks in local gas distribution systems in the U.S., and that leakage from these systems was five times greater than the amount estimated by the EPA.
Gas can be released intentionally by a utility to lower pressure or empty pipelines for maintenance, or can be released unintentionally due to wear, equipment failure, natural causes, or accidental force or puncture.
Gas leaks contribute to global warming. Gas leaks reported to the federal government resulted in the release of 26.6 billion cubic feet of methane gas from 2010 through October 2021, equivalent in its effects on global warming to emissions from over 2.4 million passenger vehicles driven for a year.
