occurred when the pipestills controller reduced the opening on the induced draft guide vanes to optimize furnace efficiency.

Discharge Preventable - Yes

Notes/Remedial Actions

the furnace guide vanes were reopened and the furnace returned to its normal carbon monoxide levels. (no typical report #); this was not preventable because this is a new parameter for the Pipestill controllers; they are learning to control to the new limits and how changes in the furnace affect the carbon monoxide emissions
