Narrative
At around 10:00am on november 26, 2019, a southcross energy contractor was preparing to repair a section of pipeline located on the corpus christi alumina property. Pipeline had been isolated from the source for 7 days and was believed to be free of pressure. Following southcross energy safety manual line breaking/equipment opening procedure, a high point plug was removed to check for pressure and liquids in the line at which time the pressure in the line caused a release through the 3/4" plug hole. Southcross energy pipeline operations responded along with ehs. The inlet valves were confirmed to be closed and the line remained isolated. Miller environmental, the contracted osro for southcross energy was contacted and arrived on-site to begin response and remediation activities. Approximately 1029 bbls of liquids and 18k scf of gas were released. The liquids were contained within the industrial site evaporation ponds. A valve was installed on the open plug at approximately 15:15 on november 26, 2019 remediation of the site was completed on december 3, 2019. Repair of the line was completed on december 5, 2019.
