A chemical release at a business in Frog Level closed down U.S. Highway 13/264-A for more than three hours today.
The accident happened at Foss Auto Salvage at 4558 Highway 13, just outside of Greenville.
Emergency management officials say employees of Foss were evacuated, but no other businesses or homes were affected.
WITN News has learned several employees of Foss were transported to the hospital as a precaution.
A three mile section of Highway 13/264-A was shut down between Frog Level Road and Davenport Farm Road.
At first authorities believed the chemical was chlorine, but they are now re-evaluating exactly what was inside the tank.
Noel Lee, Pitt County Emergency Management Director says a small amount of chemical escaped from a storage tank this morning. He tells WITN News winds helped dissipate the chemical.
Noel says a valve on the H-cylinder tank was compromised. An H-cylinder tank is about 9 inches wide and 55 inches high.
WITN will have a full report at 5 & 6 tonight.
