Hersman will provide an overview of the NTSB’s ongoing investigation into the cause of a natural gas transmission pipeline rupture that occurred in Sissonville, West Virginia on Dec.11, 2012.

Accidents involving pipelines continue to be a significant transportation and public safety concern for the NTSB which is why improving pipeline safety was added the agency’s Most Wanted List of transportation safety improvements this year.

The committee is meeting at the Robert C. Byrd United States Courthouse in Charleston, West Virginia.
