The National Transportation Safety Board (NTSB) has just released a preliminary report on what caused a series of explosions and fires in a natural gas pipeline system 25 miles northwest of Boston in mid-September (see Local NatGas Pipes Explode Near Boston Killing 1, Injuring 25). The NTSB confirmed that the cause was overpressurized pipes due to workers capping off an old pipeline that contained sensors telling the system to pump more gas than needed. The question becomes, Who’s at fault? NTSB says the fault lies clearly Columbia Gas themselves.
