Narrative
On monday dec 10th 2018 at approximately 6:50am mst, local operations personnel discovered a release of ~12 barrels of crude oil to the soil which was contained within the tank dike, while doing normal station inspection at guernsey station in guernsey, wy. The weather at the time of discovery was clear and cold with temperatures ~12f. The roof drain line appears to have failed allowing oil to migrate into the roof drain line system designed to drain water from the exterior of the roof. The lower roof drain valve froze, the valve body split causing the release. The tank was pumped down and clean up was completed on dec 11th 2018. The tank was taken out of service and cleaning/repairs are scheduled to begin ~jan 7th 2019. ** update** tank repairs have been completed, the previous drain system was a pivot master that had failed at 2 joints which introduced crude oil in the water drain system. The drain system was replaced with a coflexip drain system which eliminates several joints within the system. A frost free valve was also installed at the bottom of the drain system.
