Narrative
At approximately 1230 cdt on 31jul17 cpl was notified of a potential release on our pipeline row near fannett. The landowner noticed intermittent bubbles in standing water on the row. Cpl personnel arrived onsite & confirmed presence of a hydrocarbon release on the 8" pt. Arthur to mt. Belvieu propylene line of approximately 1 bubble per minute in the standing water. The pipeline was shut down, blocked in and purged with nitrogen. The pipeline was excavated and a short section of pipe containing the weld with the pinhole leak, was cut out and replaced. An ili was performed in 2013 and the anomaly was too small to be detected. The pipeline was restarted @ 1423 on 8-3-17.
