The U.S. Environmental Protection Agency says no chemicals have been detected in the air near an oil train that derailed and burst into flames in western Illinois.
The agency said Friday that it's conducting air monitoring, taking water samples and setting up booms to keep oil leaking from rail cars from reaching nearby waterways.
BNSF Railway says 21 of the train's 105 cars loaded with crude oil from the Northern Plains Bakken region derailed Thursday in a wooded rural area south of the city of Galena, where the Galena River meets the Mississippi.
The company says a resulting fire spread to five rail cars. No injuries were reported, the cause of the derailment hasn't been determined.
