Narrative
On november 14, 2013 at 0712 cst a crude oil leak, of approximately one barrel, occured on the tinsley 8" pipeline near rolling fork, sharkey county, ms. Enbridge houston control center received a call at 0712 cst on 11/14/13 from a landowner about a possible leak on his property from the tinsley 8" pipeline. The control center notified local operations of the possible leak at 0714 cst. At 0716 cst operation immediately shut down the pumps at the tinsley station and began emergency operations to isolate the section. Operations arrived at the possible leak site at 0756 cst and made confirmation the leak was from the tinsley 8" pipeline. At 0810 equipment arrived on-site, allowing operation to construct an earthen dam to contain the crude oil leak. The national response center was telephonically notified of the incident on 11/14/13 at 0913 cst. Evcavation revealed a pinhole leak which appears to be caused by internal corrosion. A temporary clamp was installed on the pipeline while clean-up and soil remediation occured. The msdeq and the US epa both made on-site visits and approved of the clean-up and remediation. A new section of pipe was installed on 11/16/13 and the pipeline was restarted on 11/17/13. The failed section of pipe was sent to a laboratory for failure analysis. Enbridge is still awaiting results of the failure analysis and will submit a supplemental report once additional data is analyzed and cause can be determined. Supplemental report submitted on 2/3/14 to correctly identify the type of interanl corrosion, in part g, identified by the third party lab analysis. Please find attached, a copy of the lab analysis performed by stress engineering services on the failed section of pipe for additional details and conclusions.
