Notes/Remedial Actions
They had an upset on a charge gas compressor and had to flare. They shut off the valve to stop the flaring. LDEQ received Exxon's report on 11/7/08. The release to the flare occurred as a result of incorrect pressure set point of the flare relief valve on the compressor suction. It was lowered during a previous upset and inadvertently not changed to the normal operating conidtions. Deferred until next inspection. Initial report says 120 lbs of ethylene were released but later report says 104 lbs. RQs exceeded for ethylene.
