Narrative
Anr southwest lineville ia compressor station experienced an esd event at 16:42 cst on february 12. 2012. The initial cause of the esd is believed to be a failed copper tubing oil line, unit 705 that caused a flash fire. The fire detection resulted in the esd of the compressor station. During the isolation and blow-down it was discovered that one of the station isolation valves did not travel to its desired isolation position resulting in a reportable gas release. Also, it was discovered that the valve actuator was not mounted on the valve in the correct position and that caused the valve to malfunction. The venting of gas was stopped by field personnel at approximately 17:36. Initial calculations estimate approximately 21 million cubic feet of gas loss.
