NEW YORK (AP) — Federal investigators say a poorly welded joint in a Con Edison gas line and a break in an old city sewer line were the likely causes of an explosion that killed eight people in New York City.
They say the joint’s weakness was exposed when the soil beneath it was undermined by the sewer break.
The National Transportation Safety Board issued its conclusions about the March 12, 2014, blast in East Harlem after a meeting Tuesday in Washington.
The panel also issued a finding that the failure of a dispatcher to make a follow-up call to the Fire Department of New York may have prevented a partial evacuation of the two buildings that were destroyed.
Con Ed says the broken sewer was responsible. The city says the sewer finding “appears unsupported by the facts.”
