Accident Classified As: Reportable Quantity
On July 11, 2013, the Baton Rouge Refinery experienced an oil spill to soil at the West Complex of approximately 2.7 barrels. During a raffinate transfer, a leak developed on a block valve flange due to unbalanced gasket stress. Upon discovery, the transfer was immediately stopped and the line was steamed out. This event resulted in an exceedance of the LDEQ reportable quantity for oil to soil.
This release was caused by unbalanced gasket stress as a result of thermal cycles.
Immediately upon discovery, mitigation measures were initiated, the spill source was isolated, and soil remediation began. Soil remediation was completed on July 13, 2013 at 4 pm. Gasket was replaced and thermal cycles will be reduced procedurally. The contaminated soil had been removed, and no groundwater impacts are expected.
