Summary of Incident
On the morning of January 2, 2005, a report to the National Response Center indicated an explosion and fire has occurred at the Teris LLC facility in El Dorado, Arkansas. The initial explosion occurred at approximately 0800 hours.
The facility reported initially that an employee attempted to extinguish a small fire within a warehouse storing various waste containers, but that the fire soon grew out of control.
The cause of the accident is not addressed within this report.
Response organizations (El Dorado Fire and Police Departments, as well as the Union County Sheriff Department) quickly responded and established a unified command with the Teris personnel to establish a strategy and response procedures for dealing with the emergency.
Local responders closed nearby streets, as well as evacuating approximately 200 residents downwind from the facility.
EPA Region 6 dispatched its Airborne Spectral and Photographic Environmental Technology (ASPECT) plan to monitor the plume. Preliminary review of the data collected by ASPECT showed low concentrations of trimethylamine in the immediate downwind plume. No other significant compounds or concentrations were detected.
Fire fighting was conducted by Teris personnel on-site, with off-site assistance from the local response organizations.
Due to the reactive wastes involved in the fire, water was not used as an extinguishing agent. Efforts focused on cooling areas not involved in the fire, as well as movement of materials not involved.
By 1900 hours on January 2, local officials lifted part of the evacuation area. By 1600 hours on January 3, all evacuations and road closures were lifted.
On-going monitoring of the ambient air was conducted by the Center for Toxicology and Environmental Health (CTEH), who was contracted by Teris. Additionally, EPA START contractors monitoring throughout the community.
No significant concentrations of contaminants were detected during the air monitoring efforts. CTEH did detect elevated levels of particulate matter immediately adjacent to the scene.
Sampling was conducted by Teris, with EPA and Arkansas Department of Environmental Quality (ADEQ) coordination, from fire suppression runoff. These samples were to be analyzed to determine proper disposal of this water runoff.
Additionally, wipe samples were collected by Teris (CTEH), in coordination with EPA, ADEQ, and Arkansas Department of Health (ADH) at 10 locations within the community.
Teris contracted with a remediation company (HEPACO) to relocate drums not involved in the fire, as well as remediation of the warehouse after the fire is extinguished.
EPA discontinued air monitoring and demobilized from the scene on January 6. Teris continued to work with local response officials, as well as ADEQ and ADH, on remediation efforts.
A review of the response was scheduled on conducted by EPA with State and local officials on
All attendees at the review agreed that the response was handled professionally and to the best of the capabilities of the local response officials.
