Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: Seal or Gasket

The oxo-alcohol unit has a heptene leak at the exchanger.

Discharge Preventable - No Information Given

Notes/Remedial Actions

Leak was noted at 9 pm and was leaking at 100 lbs/hr. They used steam to volatilize/knockdown the heptene to keep it in a localized area. The facility did not have a shelter in place and the chemical did not leave the facility. Plant called because they believed the RQ might be exceeded before the repair was complete. Due to no reported excursion of chemical from the plant and no shelted in place no response was deemed necessary at that time. LDEQ requested that any change in situation be notified to re-evaluate the situation and required response. The plant's written report said no reportable quantities were exceeded.
