A U.S. Senate committee is holding a hearing in Massachusetts to review the response to the natural gas pipeline explosions in the Merrimack Valley.
Democratic Sen. Ed Markey says the Senate Committee on Commerce, Science, and Transportation will convene a full committee hearing Monday in the South Lawrence East Middle School gymnasium.
The hearing will focus on responses to the Sept. 13 explosions and fires in Lawrence, Andover and North Andover that killed one, injured about two dozen, and damaged more than 100 structures.
Among those scheduled to appear are the chairman of the National Transportation Safety Board; Steve Bryant, president of Columbia Gas; and Joe Hamrock, president of Columbia's parent company, NiSource.
The hearing will be available for live online viewing at the Commerce Committee website and translated into Spanish.
