Cause: Notification made that Placid's #1 Incinerator was emitting higher than permitted sulfur dioxide emissions during the start up of the #2 Sulfur Plant.

Followup:

Notes: Refinery rates were being increased from a recent turnaround and excess emissions continued occasionally throughout the early morning before comping back below the 250 ppm concentration permit limit. Placid calculated the excess emissions that occurred during the #2 Sulfur Plant startup and determined that they were less than the established RQ. The sulfur plant was operating at less than 50% of its design load during the incident. Placid will ensure any excess emissions are accounted for in other applicable reports.
