Accident Classified As: Below Reportable Quantity (BRQ)
On November 29, 2014, Motiva Enterprises reported a potential sulfur dioxide release which occurred at the facility due to an operational upset on Motiva's Tail Gas Treatment Unit No 4 (TGTU-4). Motiva's Sulfur Recovery unit #1 tripped and diverted gas to the TGTU-4. There was too much feed to one unit to burn effectively and gas was routed to the incinerator stack. The incident was initially reported as a potential 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 RQ.
