Narrative
On november 15, 2016 a welding crew was finishing the final weld of a type b in-service reinforcement sleeve at mp 647.7 on the p62 pipeline. At approximately 16:46 a flash fire occurred from the area between the external sleeve and the line pipe. The flash was reported as 3" in length and similar to a pilot light in flame size and intensity. The crew shut down work, notified pipeline control, and began monitoring the area. At that time, the source of the lel was suspected to be from the bondo curing under the sleeve and not from an active leak. The site was monitored throughout the night to determine the source of the lel. On november 16, 2016 at 10:01 the source of the lel was confirmed to be from a leak under the b sleeve, and the nrc was notified at 10:39. The pipe was repaired with the installation of an oversleeve and was returned to normal operation november 30, 2016.
