Repotedly, No Alarm Sounded When The West Virginia Pipeline Exploded
When the 20-inch gas pipeline by I-77 in West Virginia ruptured in 2012, nobody at pipeline operator, Columbia Gas Transmission, knew it. Now, the National Transportation Safety Board is trying to find out why. NTSB member Robert Sumwalt says no warning went off in the operating company's control center in nearby Charleston, so investigators are going there to interview staffers and review data. The explosion shut down the freeway and leveled at least four homes. No one was killed or badly injured.
