Narrative
At approximately 9:35am on november 19, 2019, southcross energy gas control received a call from frontier industries (sub for corpus christi alumina) indicating they cut into a 12" condensate pipeline and it was leaking. Frontier industries relayed to gas control that there was no fire or explosion and there were no injuries. Gas control called the pipeline operations tech for the area to respond. Pipeline ops responded and installed a temporary clamp on the line. When it became evident that the incident was not as easily contained as originally thought because of the location of the cut being very close to the pipe support and it would meet the requirements for reporting, the call was placed to the nrc. The inlet valves were manually closed to isolate the line. Bunker dams were built under the leak to contain the leaking liquid. 0.5bbl of liquid was released to the ground adjacent to the pipeline. Miller environmental, the contracted osro for southcross, conducted cleanup and remediation activities under the direction of southcross. Prior to this incident, the pipeline was marked with signs at both locations where the pipe protrudes from the ground. Cca did not call the number on the signs when they were preparing for their project and cca marked the pipe for removal during their site remediation process. Southcross was not informed of the work, and the footage from the previous flyover did not indicate that any work would be happening on the southcross pipe.
