Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: Equipment Failure

Facility was recovering from an unexpected shutdown of the benzene reduction unit. The reformer unit, which had earlier shut down, was in the process of restarting. During this restart, a gaseous stream was directed from the reformer separator vessel into the north flare. Exceedences of the north flare's NOx permit limit occurred during this period, and they will be reported in the upcoming Title V deviation report. There were no CEM exceedences from operating units. Elevated SO2 readings were measured at the #3 SRU incinerator; however, this unit had been shut down earlier and flow through the incinerator was negligible. No RQs released.

Discharge Preventable - No Information Given
