Narrative
The evangeline ethylene pipeline system was divested to boardwalk petrochemical pipeline, llc on novembrer 8, 2014. This "original" report is submitted by chevron petrochemical pipeline llc, federal opid no. 31554 in behalf of boardwalk petrochemical pipeline, llc due to the fact that boardwalk has not yet been assigned a federal opid number. Boardwalk petrochemical pipeline, llc will submit all "supplemental" and "supplemental/final" written reports regarding this "accident." the "narrative description of the accident" is will follow on a "supplemental" written report by boardwalk petrochemical pipeline, llc. 11-19-15: boardwalk experienced a leak on its evangeline pipeline on october 10th, 2014. As a result of the leak, boardwalk was issued a cao by PHMSA on october 20th, 2014. The cao required boardwalk to develop an ivrp that would address the integrity of the leak. A failure analysis of the leak concluded that the leak was the result of a pre-existing flaw in the lf-erw seam. As described in the ivrp, boardwalk chose to run in-line inspection tools to identify other potential flaws in the pipeline. Anomalies of critical size detected by in-line inspection tools were addressed through pipe replacement or repaired. At this time, all inspection and repair activities required by the ivrp and cao have been completed.
