Narrative
Contractors discovered a small quantity of bubbles on the yscloskey right-of-way surface in a low area which had an accumulation of water due to heavy rains. The pipeline was already shut down for other maintenance activities and precautions were taken to shut the nearest upstream and downstream mainline valves. Due to other pipelines in the right-of-way, enterprise was not able to determine the leak source immediately. Excavation was performed at the site where it was determined that a stopple fitting was leaking. The nrc and la dnr were immediately notified when it was determined the expected cost of repair would exceed $50,000. A custom clamp was installed around the stopple fitting to stop the leak and the pipeline was returned to service. Failure of the completion o-ring seal is likely to be the cause of the leak.
