Narrative
At 2:00 pm, a tank volume change occurred and operations personnel discovered a leak in the cushing south terminal on tank 3013. The oil made its way via ditch to a small containment pond west of tank 3013. The oil overflowed from that containment into a nearby tributary to wildhorse creek and made its way into the large containment pond in the south terminal. Crews constructed dams to ensure the oil remained on the south terminal property. The suspected tank line associated with tank 3013 was evacuated and isolated. Oil in containment ponds was recovered by vac truck and stored in tanks 3009 & 3010. Piping was exposed and failed pipe will be assessed based on facility integrity plan, cut out and shipped to dnv for further investigation. Approximately 5,000 cubic yards of contaminated soil has been removed from release site. The soil has been moved to on site containment for testing and remediation. The recovery of 17,000 bbls of oil/water is currently being separated. Once complete, a supplemental report will be filed with the revised volume of commodity recovered. Remediation and cleanup is still underway and is nearing completion. Crews are currently working on seeding the creek banks and conducting daily monitoring of the south containment pond ensuring the water quality out flow meets standard. Update 12/18/13 - cleanup, remediation and analytical data collection are complete. The banks of the creek have been restored to pre-existing conditions. Monitoring of the remediation site and water quality are also complete. Re-vegetation inspection will continue in 2014 to ensure remediation efforts at the site.
