TEXAS CITY, Texas (AP) — Officials say they've lifted an order for residents to stay inside after power outages shut down three Houston-area refineries and a chemical plant.

Homeland Security coordinator Bruce Clawson says a "shelter-in-place" order for Texas City was lifted early Tuesday afternoon.

Residents had been advised twice since Monday night to stay inside after power failures shut down a Dow Chemical plant and three refineries, including a BP unit where a 2005 explosion killed 15 people.

Officials say there have been no immediate reports of hazardous emissions. It's not yet known what's caused the outages.
