US Steel announced that Midwest Plant in Portage plant is back up and running after being shuttered for a couple days following the discharge into the Burns Waterway that closed beaches, shut down a nearby drinking water treatment facility and triggered sampling by local. US Steel spokeswoman Ms Amanda Malkowski said “The discharge has dissipated. We are continuing to investigate but were able to stabilize the system. There are no indications of permit level exceedances for hexavalent and total chromium, as those sampling results came in well below permit limits. The Midwest Plant was shut down as a precaution, and we continue to coordinate with agencies to collect additional samples to monitor the situation.”US Environmental Protection Agency’s Indiana Department of Environmental Management confirmed that preliminary samples taken from an iron discharge from the US Steel Corp’s Midwest Plant in Portage do not indicate any health risks for people who may come into contact with the water. Indiana Department of Environmental Management said preliminary results of samples collected show the reddish-orange discharge from the plant’s outfall was caused by high levels of iron. The agency also said the discharge amount was below the levels allowed by US Steel’s National Pollution Discharge Elimination System permit.Indiana Department of Environmental Management said federal and state agencies are investigating environmental impacts, the cause of the discharge and possible Clean Water Act compliance issues.US Steel had shut down operations at its Midwest Plant in Portage in Indiana US on 26 September as a precaution after experiencing an upset condition with the finishing line wastewater treatment plant.
