On Monday, May 4, 2009, about 5:10 a.m. eastern daylight time, Florida Gas Transmission Company's (FGT) line 100, an 18-inch-diameter natural gas transmission pipeline, ruptured about 6 miles south of Palm City, Florida. The rupture occurred in a sparsely populated rural area of Martin County and displaced about 106 feet of buried pipe onto the right of way between Interstate 95 (I-95) and the Florida Turnpike (SR-91). An estimated 36 million cubic feet of natural gas was released during the accident without ignition. Two parallel FGT natural gas transmission pipelines in the same right-of-way were undamaged. Three minor injuries were attributed to the rupture: two people were injured escaping from a vehicle that lost control and ran off the turnpike, and one member of the Palm Beach County Sheriff's department walked through a dense cloud and inhaled natural gas. The rupture occurred between two automatic shutoff valves (ASV), but only one valve shut in response to the pressure drop on the pipeline.
