Narrative
On 10-18-18 at approximately 10:50am, energy transfer experienced a release of natural gas on the 3045 aqua dulce to loma blanca system in kingsville, tx. Energy transfer personnel arrived on site at approximately 11:08 am and identified at 11:10 am that the pipeline belonged to energy transfer. Company personnel immediately proceeded to shut in pipeline by shutting in the upstream mainline valve and downstream mainline valve at 11:35am and 12:07pm respectively. The affected pipe segment was cut out and sent to a laboratory for testing and replaced with pre-tested pipe. Energy transfer ran multiple ili inspection tools to verify pipeline integrity. The pipeline will be brought back to normal service following successful ili inspection. The cause of this release is currently under investigation. 48hr follow up nrc # 1227958. This facility is under the jurisdiction of the texas railroad commission. Update made on 3/29/2019 the cause of this release has been identified as external microbiologically induced corrosion. The pipeline was brought back to service with no pressure restrictions on 3-21-19 following a successful ili assessment. Update made on 9/6/2019 we received a final root cause analysis from a 3rd party contractor. Their analysis attributed the cause of the failure to external corrosion which led to a ductile overload. In an effort to prevent reoccurrence , energy transfer will be conducting additional verification digs on this system and a close interval survey will be conducted in conjunction with the next scheduled in line inspection.
