Narrative
At 10:45 a property owner notified field personnel working at eureka station of dead vegetation on his property. The area of concern was located less than 1 mile from the station. Upon visual inspection, operations control was notified and the pipeline was immediately shut down. Emergency response procedures were implemented. Impacted soil was excavated, profiled, and properly disposed. A temporary leak clamp was installed to stop the release. In order to permanently repair the release site, the line required startup to displace the gasoline batch with a diesel batch to ensure safer working conditions for welding and reduce hazardous vapors. A pressure reduction was implemented and a 30 minute static test was conducted prior starting up the line for displacement activities. Personnel were stationed at the leak site to monitor conditions during the gasoline displacement. Once the gasoline batch was displaced with diesel, drainup activities were completed on the pipeline and the affected pipe section was removed and replaced with new pre-tested pipe. Metallurgical analysis indicates the release was caused by a manufacturing defect known as a penetrator in the erw seam. Penetrators are usually associated with contamination of the coil edges prior to coming into contact to form the erw seam. 48-hr nrc update: report 1218724 on 7/18/18, 09:53 supplemental/final filed updates (09/07/2018): part a4, a11, a18 c3a, c6, g5-1, g5-2, g5-4, and part h narrative
