Narrative
On 8 november 2018 at 10:25 ct, a contract employee, while conducting a close interval survey, observed bubbling from the ground above the anr lateral 703 south jennings line. Upon discovery of the condition, the employee contacted the area office, who dispatched a qualified technician to shut in valves to the 703 lateral and investigate the source of the leak. The initial field investigation determined that the source of the bubbling was due to leak on the pipeline. At 12:05 ct, an incident was reported into the national response center (report #1229862). A courtesy call was also placed the PHMSA accident investigation division (aid) to inform the division of the incident. Following the discovery of the leak, actions included the reduction of pipeline pressure from discovery pressure of 976psig to 100psig, completed . On 12 november 2018, repair crews arrived at the site to repair the pipeline. On november 13 prior to excavation, pipeline pressure was reduced to 20psig. On 15 november the pipeline was exposed, the coating was examined, and a defect was found on the girth weld. It was determined to repair the leak by placing a type-b pressure contain sleeve across the defect. On 16 november, the type-b sleeve was welded onto the pipeline and the repair was completed. The defect was limited to a single pin hole located at the 06:00 position on the weld with no anomalies observed near the girth weld. The pipeline was purged, loaded, and returned to service at 14:00 on november 17, 2018.
