Notes/Remedial Actions
For the FCC, the tower was returned to normal pressure and the pressure transmitter on the overhead condenser was repaired. The small ground fire was extinguished. This follow-up letter was delayed due to Hurricane Katrina This is a letter rescinding the 8/27/2005 notification for Sulfur Dioxide (S02), Hydrogen Sulfide (H2S), Nitrogen Dioxide (NO2), and Hydrocarbons (non-speciated VOCs). Upon further review, the total amounts were estimated to be less than reportable quantities. Nitric oxide was released to the atmosphere through the refinery Number 1 flare.
