***EXERCISE*** Lewisville Bridge Radiation ***EXERCISE


At approximately 7:30 am on July 11, 2005, a tanker truck carrying 8600 gallons of gasoline heading south on I-35E ran into a cargo van, also heading south, over the Lake Lewisville bridge. There was an explosion and fire. Both drivers were killed instantly. Local Fire Departments from Corinth, Lake Dallas, Lake Highland, and Lewisville responded with 3 trucks and 15 firefighters. Local Police from Corinth, Lake Dallas, Lake Highland, and Shady shores, Sheriffs from Denton County, and personnel from Texas Department Public Safety (DPS) have shutdown access to I-35E north and southbound lanes near the incident scene. Denton Water System personnel are on the scene as well since their city water intake is just west of I-35E. The integrity of the bridge is in question.

Further investigation of the accident revealed radiological isotopes were being transported by the cargo van. The cargo van was carrying 1000 Curies of Technetium-99m, 50 Curies of Xenon-133, 500 Curies of Iodine -131, and 10 milliCuries of Phosphorus-32 for a nuclear medical laboratory. The cargo van was licensed to transport radioactive materials and was fully in compliance with state and federal regulations at the time of the accident.

An EPA OSC has been reported to be severely injured and in transport to a local hospital. No other injuries have been reported at this time.

The Texas Department of State Health Services (DSHS) and the Texas Commission on Environmental Quality (TCEQ) have asked for EPA’s assistance in conducting air monitoring and assessing the area and providing recommendations for evacuation.

EPA’s IMT has been activated at the RRC. The EPA response team (OSCs and START personnel) have arrived at the Command Post being set up at Lewisville High School (1098 W. Main St, Lewisville, TX). The Command Post has been determined to be clean.
