Narrative
On july 22, 2015 at 1100 hours, a third party pipeline operator discovered a leak on a common right-of-way. Valero was notified of a possible leak on the c 959 pipeline at 1200 hours and arrived on site at approximately 1230 hours. The pipeline was already down therefore the only action required was to confirm isolation. After excavating the site and identifying the location of the leak, a temporary clamp was installed to evacuated crude oil from the pipeline. The pipeline was cleared of crude oil and the affected pipe was cut out and a pressure tested replacement pipe was welded. A determination was made on july 28, 2015, that the cause of the leak was microbial internal corrosion. Affected soil was remediated and the pipeline was made available for return to service on august 3, 2015. Final report 12-14-2015 updated part a and part d.
