|Pump at the lift station from the API unit||Cause: There were mechanical issues and seal failure with the main lift pump, which pumps to the waste water holding tank (T-79). The pump was taken out of service, during which time untreated process waste water from the grit separator flowed directly into the Aerated surface impoundments.|
Notes: Maintenance craftsmen made necessary repairs. There were failed attempts to start the backup belt-driven pump, but it cycled 3 times and lost prime, and operations was unable to re-prime it. As of 02/21/12, maintenance craftsmen were working with the repairs and were expected to complete them. The refinery letter advises that the bypass was not expected to cause any additional problems with effluent limits.
