Hydrocarbon began to leak into the cooling water through the cooling cOil. | Hydrocarbon leak on cooling tower #4 was discovered 12/21/2006 but the department was not notified of the leak until 01/17/2007. According to Mr. Driver the leak tracking form was not initiated because on 12/21/2006 because the reportable quantity had not been reached at that time. Pump JP244A was repaired on 03/12/2007. CITGO has initiated a failure analysis review to determine how this incident occurred, and what controls need to be implemented to prevent a recurrence. Despite early detectio leak on 12/21/2006, Citgo claims leak was not preventable because CITGO had no indicaton that this pump had a problem." |
