Part of a Texas City plant was evacuated for a short time Wednesday morning.

Officials at the BP Texas City plant issued a Level 3 evacuation order for one of the processing units at the plant at 10:20 a.m. Employees and contractors were removed from the unit because it was not processing sulfur dioxide correctly. Sulfur Dioxide was discharged out of a tall stack and was not being burned off, authorities said.

By 10:40 a.m., the evacuation was lifted and work resumed as normal. The Texas City Fire Department has a team inside the plant monitoring the situation.

Texas City was under a Level 1 alert with no impact on the residents.

No injuries were reported.

Sulfur Dioxide is colorless, but has an odor. The smell of sulfur could be detected outside the plant.
