Sun-Times Media Wire / AP - A steel factory in northwest Indiana apologized Friday for accidentally releasing toxic levels of cyanide in the water near Indiana Dunes, shutting down beaches and killing scores of fish.
Earlier this week, the ArcelorMittal steel plant in Portage experienced a failure in a blast furnace and released toxic wastewater into the Little Calumet River, a spokesperson for the company said.
"Despite having safeguards in place and conducting regular sampling in accordance with our permits, ArcelorMittal apologizes and accepts responsibility for the incident from the Burns Harbor facility," the spokesperson said.
The Indiana Department of Environmental Management, which is investigating the incident, said it responded as early as Monday to a report of distressed fish in the east branch of the river, the department said in a statement. Additional complaints of dead fish were made Tuesday evening.
By Wednesday, the department noted a significant amount of dead fish in the water and determined that the ArcelorMittal facility had violated its daily maximum limits of cyanide and ammonia-nitrogen in the water, the spokesperson said.
The National Park Service closed the water on Wednesday out to 300 feet at the Portage Lakefront and Riverwalk beach area of the Indiana Dunes National Park. Portions of the Little Calumet River were closed between Highway 149 and 249, the park service said. Those portions remained closed on Friday.
The trails remain open.
A Saturday ribbon cutting for an accessible kayak and canoe launch in the east branch was expected to happen as scheduled, the park service said.
Portage Mayor John Cannon said the Indiana Department of Environmental Management and others learned Monday about an ArcelorMittal mill's cyanide and ammonia-nitrogen spill, but didn't inform his city until Thursday, The (Northwest Indiana) Times reported.
"The Mayor is calling for action to be taken," Cannon said in a statement. "Further, the City of Portage will be taking aggressive action with the EPA to ensure the breakdown of communication, like this, does not occur again."
IDEM and the U.S. Environment Agency's Chicago office did not immediately respond to requests for comment on Cannon's comments left Friday by The Associated Press.
The Centers for Disease Control and Prevention says cyanide "is a rapidly acting, potentially deadly chemical that can exist in various forms" including cyanide salts, which are used in metallurgy for electroplating, metal cleaning and removing gold from ore.
