Point Source/Release | Cause | Notes |
126823 2010-10-02 | Point Source(s): condenser to coolant tower Pollutant(s):Ethylene dichloride - BRQ Vinyl Chloride - BRQ | Cause of Problem: Equipment Failure Release of ethyl dichloride and vinyl chloride due to a condenser leak to the coolant tower. | Retesting coolant tower. Amount of ethyl dichloride and vinyl chloride released is unknown. |
126824 2010-10-02 | Point Source(s): 1/2 inch valve from V2000 C Pollutant(s):Ethylene dichloride - BRQ Vinyl Chloride - BRQ Hydrochloric Acid - BRQ | Cause of Problem: Process Upset 1/2 inch flow transmitted from V2000 C starting leakin from a 1/2 inch valve resulting in the release of unknown quantities of ethylene dichloride, vinyl chloride, and a hydrochloric acid mixture. | The valve was isolated to stop the leak. Amount of ethylene dichloride, hydrochloric acid mixture, and ethylene dichloride released is unknown but below reportable quantity. |
128245 2010-07-09 | Point Source(s): piping in VCM unit Pollutant(s):Carbon tetrachloride - 11 pounds Chloroform - 23 pounds | Cause of Problem: Corrosion A pinhole leak was discovered in the process piping and a valve in the VCM Unit. The pinholes in the metal of the affected piping/valve was likely caused by internal corrosion. | The affected piping/valve was scheduled for an internal inspection during outages. It will be re-emphasized to affected personnel the importance of accurate information in release estimations and proper inspection and maintenance of equipment. Actions were taken to isolate and stop the leak. The affected equipment was shutdown, de-inventoried, and repaired. |
124335 2010-06-12 | Point Source(s): Relief valve on heat recovery steam generator #3 Pollutant(s):Natural Gas - 340,599 pounds | Cause of Problem: Equipment Failure The cause is believed to have been the failure of two pressure regulators in series on the natural gas pipeline, which then caused the pressure relief valve to open to protect the integrity of the line and equipment. The release was discovered on 6/21/10, but the LDEQ report states that the release duration may have occurred over a 10-day period beginning on 6/12/10. Relief valve on heat recovery steam generator #3 for natural gas. | Upon discovery, the release was immediately isolated. |
121465 2010-02-11 | Point Source(s): Furnace A (point source 230A) Pollutant(s):Hydrogen Chloride - BRQ | Cause of Problem: Equipment Failure Permission emissions limit was exceeded at Furnace A. A tube in the furnace convection section had failed. 143 lbs of HCL was emitted. No reportable quantity was exceeded. | No information given |
121038 2010-01-26 | Point Source(s): 1/2" line Pollutant(s):Ethylene dichloride - BRQ | Cause of Problem: No Information Given 1/2" line broke and had to isolate it to stop the release of EDC. Subsequent calculations indicated that the RQ amount of the material was not exceeded. | Secured within 30 minutes. |
121040 2010-01-26 | Point Source(s): "a column" Pollutant(s):Vinyl Chloride - BRQ | Cause of Problem: Piping or Tubing Vinyl Chloride leaking from a pinhole leak on a column. | Clamp was placed over the leak and it was secured within 40 minutes from being notified. Calculations indicate that reportable quantities were not exceeded. |
120537 2010-01-01 | Point Source(s): Isolation block valve for the RV-C204-2, column NC204 Pollutant(s):Vinyl Chloride - BRQ | Cause of Problem: Process Upset The isolation valve for the RV-C204-2 leaked through from the NC204 column. | The only way to repair the problem was to isolate and shut down the column. |
