The National Transportation Safety Board (NTSB) will meet next week to determine the probable cause and consider safety recommendations for a pipeline rupture and oil spill accident last year in Michigan.

On July 25, 2010, an Enbridge Incorporated 30-inch-diameter pipeline ruptured and released crude oil into a wetland area in Marshall, Michigan. The rupture occurred during the last stages of a planned shutdown and was not discovered or addressed for more than 17 hours. Cleanup efforts are ongoing; related costs to date have exceeded $767 million.

The meeting will take place at the NTSB Board Room and Conference Center, 429 L'Enfant Plaza SW, Washington, DC.

A live and archived webcast of the proceedings will be available at www.ntsb.gov. A synopsis of both reports will appear on the website shortly after the conclusion of the Board meeting. The complete reports will appear on ntsb.gov in several weeks.
