Accident Classified As: Reportable Quantity
Stack testing of the FCCU revealed higher than federally permitted release rates and reportable quantities of hydrogen cyanide gas.
This was not reasonably preventable. Testing was initiated as a result of new data available from other refineries using this relatively new EPA test method.
A permit notification will be submitted representing this new data and request an increase in emissions. Testing showed hydrogen cyanide release at 90 lbs/hr. No duration time was given, because emissions are ongoing. Release amount for this database represents one year of HCN emissions and was calculated using the hourly release rate (90 lbs/hr) multiplied by 8,760 hours/year.
