The company at the center of the West Virginia water crisis immediately knew a second chemical leaked from its plant into the Elk River, and told its workers in an email, according to a state environmental official.
However, Freedom Industries did not let state government officials know about the second chemical until days after the spill. And state environmental department official Mike Dorsey said most company employees did not skim far enough into the email to see that information.
It's unclear who sent the email or how many of the company's 51 employees it reached.
"The explanation I was given was that they had the information on the very first day," said Dorsey, chief of the state environmental agency's homeland security and emergency response division. "It was in an email that was being shared among company employees, but no one read far enough down the page to see that."
Freedom Industries President Gary Southern showed Dorsey the email Wednesday.
"(Southern) remarked that it should've been brought to his attention but wasn't," Dorsey wrote in an email Friday.
A chemical used to clean coal spilled from the tank into the river Jan. 9. About 300,000 people couldn't drink or bathe in the water for almost a week. Southern told environmental officials this week that a second, less toxic chemical also was mixed in the tank.
A call to Freedom Industries was not immediately returned Friday.
Those are the only chemicals that spilled, the company wrote to state regulators Thursday. The state tested for the second chemical, stripped PPH, at the water plant and scoured older tests for the substance, but found no traces. Testing will continue.
A top investigator with the Chemical Safety Board also weighed in on the spill in front of a state legislative water policy committee Friday. The federal board is one of many government entities investigating the Charleston spill.
Investigator Johnnie A. Banks said it will likely take a year until the board produces a report with findings. The panel can, however, set up public meetings to share periodic updates. The meetings would take place in Charleston, he said.
When state environmental inspectors showed up at Freedom Industries Jan. 9, they described a chemical, crude MCHM, oozing from the pierced tank through a cracked containment wall into the river.
Banks, whose team arrived Jan. 13, said a hard freeze might have helped create the 1-inch hole in the tank that leaked, which Freedom Industries has theorized.
"There was nothing that jumped out at you that said this containment was inadequate or that the tank is going to fail," Banks told reporters.
On Tuesday, Freedom Industries reached a bankruptcy court deal for up to $4 million in credit from a lender to help continue operations, an attorney said.
The bankruptcy filing freezes dozens of lawsuits against Freedom Industries. Many are by local businesses owners who say they lost money during a water-use ban that lasted several days.
Under state orders, the company still needs to relocate almost 1 million gallons of other chemicals at its Charleston plant.
