Accident Classified As: Below Reportable Quantity (BRQ)
On October 20, 2012, Motiva Convent Refinery reported a potential sulfur dioxide (SO2) release which occurred at the facility due to an upset on the Sulfur Recovery Unit (SRU) and Tail Gas Treating Unit (TGTU). The upset was caused by a trip on one of the unit's heaters causing elevated SO2 emissions.
The incident was initially reported as an exceedance of the 500 lb Reportable Quantity (RQ) for Sulfur Dioxide (SO2). However, after further calculation, the total SO2 emissions from this incident were not above the permitted limit.
