Narrative
On thursday (10/31/13), a project to install pipe extensions at stanley station was being performed. The project started by isolating the manifold from tanks 9005 and 9002. The pipe was drained to sump. Once drained, the extensions were installed as planned. An employee started to fill manifold from tank 9005. Employee went to check sump level after moving valves and discovered oil exiting the sump. He ran back to manifold and discovered the drain valve on tank 9005 manifold had not been closed which allowed oil to flow to the sump. The sump light and siren were operating when the employee found the sump overflowing. After the employee closed the valve, he contacted his supervisor to report the spill. The emergency response process operated under ics and was documented with an ics 201 packet. Enbridge environment and safety worked to ensure safety of response and compliance with spill response regulations. The employee started using diapers and berms to lessen the environmental impact. The contractor foreman instructed the vac truck driver to back up to sump and removed oil from the sump to limit the amount of oil on the ground. Once the site was secure, benzene testing occurred, vac truck started to clean up free product. Cleanup operations (using hydrovac trucks) started immediately and cleanup was completed by evening. An estimated 50 cubic yards of contaminated soil was removed from the area and will be hauled to an approved disposal facility.
