Narrative
Approximately 279 barrels of crude oil were released from a tank mixer at wolfbone ranch station. The date and time of the release (part a q4) is indicative of the earliest possible time the release could have started, as it was the last time the station had been visited and confirmed crude oil was not being released. The national response center (nrc) was contacted on the basis of estimated costs exceeding $50,000 (initial nrc report #: 1286874, and 48-hour nrc follow-up report #: 1287079). The cause of the incident was determined to be equipment failure of the seal as a result of a manufacturing defect on the bolts and bearings. To prevent future releases, plains has replaced the seal, bolts, and bearings as recommended by the manufacturer, and is conducting further investigations to determine if other mixers of this brand and model require new bolts and bearings. 09/24/2024 - updated by PHMSA per operator approval.
