Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: No Information Given

Citizen complaint filed on 11/8/2013 reporting a foul odor causing headaches. The Liquid level the the external floating roof gasoline storage tank (Tank 200-1) was lowered to a point where the vacuum breakers on the roof started to open. These vacuum breakers are designed to protect the tank when the floating roof is landed onto its legs. With the vacuum breakers open, VOC emmissions from 200-1 would increase above their normal baseline. The level in the tank was lowered, which caused the system to act in such a was as to prevent back flow from the tank into the system (the vacuum breakers opening), however, we are unsure as to how the liquid levels go to be low enough to cause this to happen.

Discharge Preventable - No Information Given

Notes/Remedial Actions

Once this condition was discovered, the liquid level in the tank was increased until the vacuum breakers closed. This opening was logged as a Title V permit deviation, and is to be reported in the next semi-annual Title V deviation report.
