AL, JEFFERSON
Narrative
Operator crews were in the process of replacing a valve on a 12" steel main at the referenced address. A segment had been disconnected and removed by use of stopper fittings. The remaining in-service main was not secured by using anchors or other methods of reinforcement. Line pressure forced this segment of pipeline loose from an upstream coupling at approximately 12:45 pm on november 4. Gas was stopped at 3:45 pm the same day. At approximately 4:20 pm the operator determined that this event would be reportable due to estimating the unintentional release of gas to exceed 3 million cubic feet.
