Narrative
Approximately 20 barrels of crude oil were released from a 12inch trap bypass line at cushing jct / cimarron tie-in station. The date and time of the release (part a q4) are indicative of the earliest possible time the release could have started based on the last time the location had been visited and confirmed to be no release of crude oil. The cause of the release is attributed to internal corrosion. The mechanism of corrosion and associated preventative measure will be provided in a supplemental report.
