Narrative
At approximately 2:15 am, at dcp midstream wilbreeze pump station located near edna, tx, the shutdown valve esd120 inadvertently went closed causing a thermal relief valve to lift and vent approximately 34.6 barrels of ngl to atmosphere. The operator at the houston control center called an ngl technician at approximately 2:30 am to investigate. The ngl technician arrived at the site at 3:20 am and began to investigate the closure and returned the valve to the open position. At approximately 3:30 am, the technician saw a flame on top of the vent stack. It is presumed that static electricity or a lightning strike from a storm in the area ignited the ngl vapors on top of the vent stack. The technician then notified the operations supervisor at approximately 4:01am. The investigation determined that esd120 inadvertently closed due to a transient voltage spike/dip from the bad weather.
