CROSBY, TX - SEPTEMBER 04: Chemical drums that had washed away from the Arkema plant during flooding caused by Hurricane and Tropical Storm Harvey are trapped by the facilities border fence on September 4, 2017 in Crosby, Texas. Today authorities lifted an evacuation order for a 1.5-mile perimeter around the facility which was put in place after the storm knocked out power, back-up generators and a nitrogen cooling system used to cool highly-volatile organic peroxides which the company warned would explode if they were not kept cool. Harvey, which made landfall north of Corpus Christi August 25, dumped nearly 50 inches of rain causing widespread flooding in Southeast Texas. (Photo by Scott Olson/Getty Images)
