Narrative
On 8/6/17, a contractor crew was preforming soil remediation related to a spill that occurred on 8/4/17. At approximately 10:45 cst, their excavator struck a buried tubing line near the line 01 control valve inside baton rouge station. Striking of the tubing line broke the nipple below the shut-off valve on the tubing valve-tree and resulted in a release of approximately 12.3 bbls of gasoline inside the access well. The inspector immediately notified operations which contacted the control center and isolated and bypassed the station at approximately 10:56. Operators locked-out and drained the station piping which stopped the leak at approximately 11:30. All released product was contained on company property within the access well. A vacuum truck that was staged nearby was immediately deployed to the access well where the product was contained. The parish lepc and state of la were each notified. A technician was mobilized who replaced the damaged tubing section at approximately 14:15 and baton rouge station ln01 was restarted at approximately 14:35. Product recovery and cleanup activities were completed on 8/6/17 by 11:30. Initial investigation indicated tubing was struck due to failure to follow colonial's excavation procedure; did not properly locate/verify depth of tubing prior to excavation. Excavator operator, spotter and inspector oqs were suspended as a result. Final report update: incident analysis was completed on 1/24/18, confirming the apparent cause and provided recommendations related to locating buried tubing. Regarding zero commodity costs, the released product was recovered from a partially water filled access well, was not contaminated, and therefore returned to the pipeline system via transmix injection.
