BRYAN, Texas (AP) - Officials are evacuating much of Brazos County to the north and west of Bryan because of a fire at a chemical plant believed to contain explosive ammonium nitrate.

The fire broke out about noon Thursday. Bryan-College Station fire dispatcher Andy Throne says the plume of smoke from the El Dorado Chemical Co. plant extends up to 60 miles from the plant.

Throne says no injuries have been reported from the fire, where fertilizer and other chemicals are blended and packaged. But he says an area up to six miles from the plant will be evacuated, including part of northwestern Bryan and a large part of northwestern Brazos County.

The plant is located about three-fourths of a mile west of Bryan.
