U.S. officials are working to secure some of the nation's most contaminated toxic waste sites as Hurricane Irma bears down on Florida.
Sen. Marco Rubio of Florida says the Environmental Protection Agency personnel he's spoken with seem "generally positive" about the prospects for toxic sites remaining secure in the coming hurricane.
But, as Rubio put it, "they can't guarantee it 100 percent." Rubio spoke with the Associated Press from the Miami-Dade Emergency Operations Center.
Florida has Superfund sites on both the east and west coasts. Rubio says EPA officials have been assessing the sites for 72 hours.
He says they think the risks to the sites are "real" but not as severe as Houston faced from Harvey, because of the Texas oil industry.
