Point Source(s) | Notes | Amount of Release |
| 84791 2005-12-23 | B-Topper Unit B-7 Flare | Cause: Piping leak at the B-Topper Unit. Due to the temperature of the naphtha steam and the elevation of the line relative to the ground, the leaking material evaporated and did not reach the ground. Followup: Yes Notes: Original letter states that the phone call to report this incident occurred on December 24, 2005, while the follow up letter states the incident occurred on December 23, 2005 at 23:45 hours. Claims all pollutants were released as liquids but vaporized before reaching the ground. Heavy naphtha release was below reportable quantities. The pumparound piping from which the leak was coming was shutdown and isolated for repair when the Unit was shutdown. A Failure Analysis was scheduled for this incident. Second attached letter states that upon re-start up of the B-Unit Topper on December 29, H2S and SO2 were possibly released but below reportable quantities | |
| 84711 2005-12-20 | Sulfuric Acid Plant | Cause: Possible release of H2S and SO2 during a routine startup of the Sulfuric Acid Plant. Followup: No Notes: Claims emission was below RQ. | |
| 84652 2005-12-17 | B-11 FLARE | Cause: Result of a shutdown of the JC-201 Compressor at the Coker II Unit. Root cause was due to an incorrect engineering design flaw in Transformer 444-S49-TRI-A protective relaying scheme. Transformer had been taken out of service to repair a secondary busing oil leak, and during re-energizing of the transformer the malfunction caused a power outage, causing shutdown on several critical pumparound pumps; the resulting loss of heat removal caused the overheated drum F-210 to fill with liquid. Followup: Yes Notes: Caused the 4.16kV tie breaker to open when the differential relay operated. A significant contributing cause of the additional flaring after power was restored was the plugging of the case drains on JC 210 compressor. Engineering calculations states that they expected SO2 released to be slightly lower than their original report, under the NRS Consent Decree, and then stating that they calculated 35,458 lbs were released. No information given on amounts of H2S or CO2 released (does not say specifically BRQ, but only SO2 was listed as exceeded permit levels). | 35,600.0 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 | 203,217.0 pounds |

CITGO believes water entered the Substation via a the joint b/w the roof and the side wall causing a fused switch failure. Loss of power resulted in higher pressure and increase in liquid levels causing flaring at B-7. Loss of amine flow and hydrogen sulfide absorption generated heavy smoking from some of the boiler stacks and upset the Sulfur Recovery Plant. Operations pnnel inadvertently overloaded the Central Amine Unit causing high SO2 emissions throughout the Refinery. The crude oil leak was caused by internal corrosion. Limited offsite impact from soot from smoking boilers. REMEDIAL ACTIONS --> A Root Cau | 237,471.0 pounds |
