FREEPORT, Texas (AP) — A leak in a Dow Chemical underground pipeline is prompting the evacuation of more than 60 homes in Freeport.

Dow Chemical spokeswoman Trish Rithaller says crews on Wednesday are expected to begin digging in an area around the pipeline, in a field, to repair the leak. The accident involves a urethane product.

She says the underground pipeline leak was discovered Sunday morning and the area has been secured.

Plant workers on Monday were dispatched to neighborhoods to advise residents to relocate to hotels and expect to be out of their homes for several days.

No injuries were reported.

Freeport is about 60 miles south of Houston.
