 NTSB to release investigative documents on West Virginia pipeline accident

As part of its continuing investigation into the rupture of a natural gas pipeline in West Virginia, the National Transportation Safety Board will open the public accident docket releasing over 1400 pages of documents on Thursday, June 6.

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.

The documents being released are factual in nature and do not provide any analysis. They include interview transcripts, photographs, and other documents from the investigation. All of these materials will be made available at 11:30 a.m. EDT on Thursday, June 6 on the following page of the NTSB’s website, here.

Additional material will be added to the docket as it becomes available. Analysis of the accident, along with conclusions and a determination of probable cause, will come at a later date when the final report on the investigation is completed.

This will be a document release only; no interviews will be conducted.
