Narrative
On 4/2/19, the control room began receiving cpm alarms into the scada system. The alarms were investigated and the system was shut down and isolated. Local operations were also notified of a smell of petroleum near knightsville, in. Field technicians were dispatched to the area and product was observed on the pipeline right-of-way and in a small creek, positively confirming the release at 10:28 est. The area was secured, emergency response was initiated, and cleanup began. Release has been determined to be 112 barrels of natural gasoline, with 7% being recovered and 93% attributed to evaporation. Excavation of pipe revealed cracks in the pipe body that began within a shallow gouge, which ultimately led to failure. The leaking defect was cut out and repaired with a full cylinder replacement. The investigation, including metallurgical analysis, indicates the shallow gouge occurred during a line lowering project in 2017. **48 hour nrc update call was placed on 08:59 on 4/4/19.
