Narrative
On 9/1/19 at approximately 08:45, operator employee was performing routine station check at sour lake station and identified crude on the ground around a section of the unit 3 pump suction line on the east texas 10" system. The operator called the control center and had the pipeline pumps shut down and then manually closed valves to isolate the release. Approximately 3 barrels of crude oil was released. The tx rrc was notified of the release on 9/1/19 at 10:31 and case no. 2054 was assigned. The area was excavated and it was identified that the failure occurred on a small section of "dead leg" piping associated with the suction line. Visual examination of the failed section indicated an internal corrosion pinhole was the cause of failure. After examination a clamp was applied to the failed section of pipe. All free product was cleaned up and impacted soil was removed for on-site remediation. To prevent recurrence the "dead leg" will be removed and all necessary below ground piping will be brought above ground.
