According to Southern Natural Gas, the leak happened at a natural gas regulator located near Livingston.
The company said an ignition of natural gas occurred for unknown reasons. A small brush fire was contained with the assistance of local emergency responders.
The line leak happened south of Livingston off of Highway 80 and Highway 28 in the Coatopa community.
Richard Wheatley, the media relations representative for Southern Natural Gas, said the situation was under control Thursday night. But according to the City's Facebook page they claim that many residents were without gas service.
The company said there were no known injuries from the incident that was reported by a citizen through a call to its Birmingham facility.
Company officials will be working throughout the night with the city of Livingston to restore gas service to residents and are continuing to investigate the rupture and make repairs.
