Cause of Problem: Process Upset

Sulfur Plant No. 2 Shutdown causing the No. 1 Incinerator to exceed the CEMS 500 ppm sulfur dioxide span until all of the acid gas load was shifted to Sulfur Plant No. 3. The increased load cause the No. 2 Incinerator to exceed the CEMS 500 ppm sulfur dioxide span until Sulfur Plant No. 2 was restarted. Both of the incinerators are permitted sources.

Discharge Preventable - No

The cause of the unit shutdown is currently unknown. The emissions that resulted from the shutdown were not preventable after the shutdown, as the alternative was to shutdown all operations, resulting in more emissions from the shutdown and startup processes.
