Cause of Problem: Instrument Failure
A compressor solenoid [computer] in the vapor recovery unit(VRU) developed an electrical short, which caused the VRU to shut down. The shut down caused atmosphere vents on Tanks 90, 282, 99, 100, 101, and 261 to open and relieve excess pressure. Released 2% Benzene and flammable gas.
Discharge Preventable - No
NO, the solenoid had an unanticipated electrical short.
Notes/Remedial Actions
Electricians repaired the solenoid and returned the VRU to service. They manually isolated natural gas flow from the tanks. Area around the tanks were monitored with gas test machines (readings below detection limit). Operation personnel monitored the area for odor.
