Narrative
On august 10, 2020 at approximately 11:30 am cdt crude oil was discovered in the tank berm of tank 3013 by field personnel performing routine rounds at the cushing terminal. The cushing control center was contacted and the area of concern was isolated and pipeline maintenance personnel began excavating to investigate the source of the release. Due to strong winds and lightening, the excavation and cleanup work was delayed. A call to the nrc was made on august 11, 2020 at 11:46 am cdt (report #1284289) once the source of the release was identified as a pinhole in the relief line to tank 3013 and it was determined that the costs would exceed the nrc reporting threshold. The 48-hour nrc notification was made on august 13, 2020 at 10:46 am cdt (report #1284450). After further investigation it was determined that internal corrosion caused the pinhole which led to the release of two barrels of crude oil. Additional integrity issues have been identified with the tank line and it is currently isolated from all sources of product until final repair determination is made. Contaminated soil has been cleaned up and disposed of at an approved site. Additional soil remediation is expected to be ongoing.
