In the three communities of Massachusetts shaken by a series of fires and devastating gas explosions, residents have lost patience, their fingers Columbia Gas. The National Transportation Safety Board (NTSB) announced that it was investigating the company.
"We will review their record keeping, compliance with procedures, procedures, training, oversight of their subcontractors," said NTSB President Robert Sumwalt.
Government records reveal at least three more serious explosions in Massachusetts, West Virginia and Ohio, all related to Columbia Gas. The company is a subsidiary of NiSource, a utility company serving more than three million customers in seven states.
A technician who broke through a gas line was responsible for the 2012 Springfield explosion that destroyed a nightclub and damaged near a dozen other buildings and injured 17 people.
In West Virginia, the NTSB has identified major safety concerns when a Columbia Gas pipeline that has not been inspected or tested since the late 1980s has corroded and broken, destroying three homes. In Ohio, an investigation revealed that an "incorrectly abandoned" service line was causing an explosion that had caused millions of property damage.
The NTSB will not say how Columbia Gas's accident history compares to other natural gas suppliers.
