Point Source/Release CauseNotes

Point Source(s):
gasket on the isocontainer

R410a - 8,247 pounds
Cause of Problem: Seal or Gasket

Tank farm operations were in the process of loading an isocontainer with R-410a when the gasket between the flange of the internal valve and the isocontainer tank failed. Operations closed both internal and external valve and attempted to tighten the flange nuts, but were unsuccessful in stopping the leak.
The point of the leak was at the gasket upstream of the internal valve and flange to the isocontainer. Operations immediately began to unload the contents of the isocontainer back to the railcar. The release did not result in any fire or explosions, and there were no injuries as a result of the incident. The release exceeded the reportable quantity of 5000 pounds of R-410a. Corrective actions have been initiated to prevent any reoccurence.

Point Source(s):
113 unit

1,1,1-Trifluoroethane - 2 pounds
Hydrofluoric Acid - 0 pounds
Cause of Problem: Start Up, Shut Down

The release was the result of a fugitive gasket leak at the man way to the HF recycle Hold Tank in the 113 unit (Trichlorofluoroethane unit). The unit was in the process of startup and the hold tank was empty and had just started to receive flow.
The flow was blocked in, the unit was shutdown, and the insulation was removed. The gasket was replaced and the flange bolts retightened. No further leak upon restart of the unit. Citizen complaints were reporting an odor described as sulfur or burnt match odor.
