$56M gas explosion settlement approved

BOSTON » A $56 million settlement between Massachusetts and the natural gas utility found responsible for a series of explosions and fires in the state in 2018 was approved by the state Department of Public Utilities.

The settlement with Columbia Gas of Massachusetts and its parent, NiSource, was agreed to in July and approved Wednesday, the state Executive Office of Energy and Environmental Affairs announced in a statement.
