Narrative
Approximately six barrels of crude oil were released within facility boundaries from the tank mixer of tank 2 at dominguez hills station. The date and time of the release (05/04/2020 at 2:00) is indicative of the earliest possible time the release could have started, as it was the last time the incident location had been visited and confirmed that no crude oil was being released. A supplemental report will be submitted pending further investigation into the cause of the incident. Supplemental narrative: the cause of the incident was determined to be equipment failure due to an incorrectly sized spring applying excess pressure to the stationary seal on a plenty mixer. The incorrect spring had been inadvertently installed by the vendor at the time of the seal reassembly. To mitigate future releases, a new mixer seal and spring assembly were installed on the mixer.
