Federal officials were investigating the cause of the wreck, but most officials were kept out of the area because of the toxic gas.
State and federal environmental officials have continued conducting air quality tests, finding either low levels or nothing at all a couple blocks away from the site. The crash site levels were higher.
“How high? We are not sure,” state Department of Health and Environmental Control spokesman Thom Berry said. The levels exceed the monitor’s limits, he said.
The evacuees will have to stay out of their homes at least until early next week. I wonder where, exactly, they are staying?
