Narrative
On july 17, 2019, at centurion pipeline (cpl) wasson station in yoakum county, texas, at 11:52 am, a station sump overflowed following a normal operations activity. Following an accident investigation it was determined that the sump, when approaching the fill level, unexpectedly released an air pocket. This release pushed oil out of the sump through the aboveground fill pot with some oil reaching the ground. The investigation concluded that installing a check valve between the sump and the fill pot will prevent future flow from the sump to the fill pot, hence preventing future overflows. Following the investigation a check valve was installed. Sumps across cpl's system are monitored for fill levels so any future events will be contained within the respective sump. High sump levels will shut stations down, hence preventing future similar events. One half barrel of oil reached the ground, all of which was recovered. No employees were injured and no other damages occurred.
