Point Source(s) | Notes | Amount of Release |
| 80735 2005-07-23 | Valve flange line between Tank 411 and Tanks 66 &67 | Cause: failed gasket Followup: No Notes: Gasket was replaced | 210.0 gallons |
| 79720 2005-06-09 | F-7 blow down drum | Cause: A-Topper Desalted Crude 301JP1B pump tripped causing F10 Desalter relief valve to open to the F7 blow down drum resulting in spill of crude from oily water sewer box located east of blow down drum Followup: No Notes: The design of the sewer box could not contain the volume of material released. | 218.0 gallons |
| 06-BB006-932 2006-09-21 | A Dock Isolation Valve | Cause: a dock perator did not completely cose an isolation valve while replacing pressure gauge at A Dock Followup: No Notes: Training and awareness | 3.0 pounds |
| 88679 2006-06-19 | B-12 flare, wastewater treatment plant | Cause: Refinery experienced a heavy rainfall event, greater than 8 inches;of rain in 36 hours. 250 psig steam lines became submerged in water and as a result the steam condensed and caused a drop in pressure, eventually stopping the flow of rich amine throughthe Central Amine unit. This resulted in the loss of acid gas production. The SROs eventually shutdown due to lack of feed. Off gas went to the B-12 flare. Rainfall runoff exceeded the available capacity of the wastewater treatment system storm water tanks and the treatment system. When the capacity of the storm water tanks was exceeded, slop oil and wastewater overflowed from the tanks into the protective dike area surrounding the tanks allowing evaporation of benzene, etc. Followup: Yes Notes: The lack of amine treatment of refinery fuel gas caused the hydrogen sulfide content in fuel gas to exceed permit limits Hydrogen Sulfide amounts exceeded not reportedÉTo increase the pressure of the steam system and to reuce hydrogen sulfide generation, emergency steam and hydrogen sulfide shedding steps were initiated. Several units feed rates were reduced to minimum and some were shut down. As soon as acid gas was available steps were taken to restart the SRUs. For each restart operations pnnel followed standard operations procedures for startup and shutdown. When the storm water tanks began to overflow, steps were taken to remove slop oil from the tank dike using vacuum dikes. The feed rte of wastewater from the wastewater tanks to | 2,226,000.0 gallons |
| 98497 2007-08-08 | Tank 85 | Cause: see notes Followup: No Notes: Leak discovered @ Reformate Tank 85 coming from 2 small holes immediately above the wind stiffener ring at the 36.5 foot level; Verbal report indicates failure of gauging system contributed to late detection of leak. REMEDIAL ACTION: A new safe operating fill height has been established below prior level. Tank 85 will be replaced. High level alarm has been lowered to prevent recurrence. | |
