A press release from Kanawha County officials, said, "At this time, Catalyst Refiners have estimated the release was approximately 950 pounds of nitric acid."
Kathy Cosco, a spokeswoman for the state Department of Environmental Protection, said her agency was notified of the incident shortly before 2 p.m. Cosco said DEP was initially told the leak involved hydrogen peroxide, but had not been told how much was released.
"We've got someone headed out there to investigate," Cosco said.
In their press release, Kanawha County Emergency Management officials said that Bayer contacted them about the incident at about 12:30 p.m., and that Bayer called Metro 911 shortly after 1 p.m.
"I made the mistake of not notifying at first," Schmidt said. "I take full responsibility."
Bayer said in a statement that it called a "precautionary shelter-in-place" for its plant workers from about 1 p.m. to 3:25 p.m. following a wind shift during the Catalyst Refiners leak.
On Aug. 24, two workers at Catalyst Refiners were transported to the hospital after a nitric acid leak at the facility.
Schmidt said that incident occurred when a light bulb in a fixture above a different mixing tank broke. He said the company believes metal from the bulb reacted with the materials in the tank, causing the spill.
Catalyst Refiners is owned by New York-based Ames Goldsmith Corp.
