2.1.1 Narrative
On the Morning of May 30th, 2010, EPA received a request from New Hanover County to investigate a fire and explosion that occurred at the Invista Wilmington Plant. Upon arrival, EPA met with Invista staff as well as the local Fire Dept. EPA learned that a fire and explosion did occur at approximately 4:40 am the morning of May 30th. The fire involved an above ground storage tank (T-6305). T-6305 contained Dimethyl Terephthalate (DMT) at a temperature above 300 degrees Farenheit. The top of the tank had separated landing approximately 150 feet away. Vapors ignited and caught fire.
The overpressure and fire is believed to have been caused when methanol inadvertently overflowed from the scrubber system into the T-6305 Tank, the elevated temperatures caused vaporization, and over pressurization which resulted in the incident.
2.1.2 Response Actions to Date
Invista shut down the process line. Invista has completed a root cause investigation and provided a report to EPA and NCOSHA. Invista is in the process of considering and implementing corrective actions to prevent recurrence. Invista investigated damage to the adjacent tanks per the Work Plan provided to EPA. Invista is continuing to evaluate the quantity of the release.
