According to the Courtesy Notification of release from Tank 15 thay is ongoing, "the fixed roof tank over pressured and caused a bulge in the roof. Several holes developed along the seams allowing the tank to vent emissions to the atmosphere instead of the vapor combuster". Venting fumes directly to the atmosphere.
Refiniery report does not indicate whether or not the discharge was preventable.
"The tank is storing heavy No.6 oil and a plan to repair or take the tank out of service for repairs is being developed and will be implemented as soon as practical",according to the refinery report. Tank is cooled and emptied. The tank will be cleaned in 30 days and repairs will be made but due to the heavy contents, this may last 6 months conservatively. SPOC states that emissions for VOCs were less than 1000 lbs and less than 10 lbs for H2S. Follow-up letter states that a discharge was in excess of of permit levels and will cause a deviation that will last longer than 7 days, but there is no indication of which pollutant they might be referring to. Tank 15 must be cleaned to repair the tears on the roof. This operation requires a completely sealed tank, therefore, breathing emissions are now going to the atmosphere and will continue until the tank is de-inventoried. Unsure of how long it will take to clean and repair the tank due to heavy storage contents, and conservatively assumes it will take at least six months to complete.
