Narrative
On 10/21/21 at 4 am during station checks and after a 30' valve (v190) was replaced in the marshland manifold, the flanges on the valve were found to be leaking upon the startup of bayou bridge pipeline. Approximately 10 barrels of crude was released onto the ground. The connection that leaked had an electrical insulation kit installed during the valve installation. After the installation, the flange bolts were scheduled to be torqued on the morning of 10/21/21, but there was miscommunication between operations and maintenance and transfer of crude down the pipeline began before the flange bolts were torqued. As a result, the flange leaked crude into a containment area. The transfer was stopped, and the bolts were torqued. A crew was called to clean up all free product and remove the contaminated soil and rock for remediation. The next morning the system was restarted and returned to normal service. Maintenance and operation crews were instructed to make sure communication is clear between them.
