Pipeline Safety Division

The Pipeline Division serves the public by investigating gas incidents and determining their cause.  This helps improve safety and prevent similar incidents in the future. Incident investigations have resulted in new safety regulations for abandoned service lines, cast iron pipe, and liquefied natural gas plants.

The Division regulates pipeline safety solely within the state of Massachusetts (intrastate).  Pipelines that cross state lines (interstate) are regulated by the Pipeline and Hazardous Materials Safety Administration within the United States Department of Transportation.

The Division also tests all gas meters in the state for accuracy and leaks. After passing the test, each meter is marked with a stamp, showing that it is approved for use.

In addition, the Division answers consumer questions and helps to resolve customer complaints. If you have a question or a complaint (except for billing problems), you can call the Division at (617) 305-3537.
