Pipeline Accident Investigation

On December 11, 2012, at about 12:41 pm EST, a buried 20-inch diameter natural gas transmission pipeline owned and operated by Columbia Gas Transmission Corporation ruptured just over 100 feet west of Interstate 77 in Sissonville, West Virginia. About 20 feet of pipe was separated and ejected from the underground pipeline and landed more than 40 feet from its original location. Three homes were destroyed by the fire after the escaping high-pressure natural gas ignited; no one was seriously injured.
