Update Oct. 5

EPA’s final sample results show the reddish-orange discharge from the US Steel Midwest Plant outfall was caused by high levels of iron. EPA’s preliminary sample results also currently indicate that the discharge was below the numeric effluent discharge limits contained in US Steel’s NPDES permit.

Federal and state agencies continue to investigate the matter to determine the cause of the discharge and possible Clean Water Act compliance issues, as well as environmental impacts and further actions that are necessary to ensure future compliance. 

At the request of EPA, the Agency for Toxic Substances and Disease Registry evaluated sample results for surface water near the US Steel outfall. Their review does not indicate any health risks from the discharge for people who may come into direct contact with the water along the Portage River Walk.


On September 26, 2021 EPA received NRC reports from both a private citizen and from the City of Portage, Indiana indicating that an orange material appears to be coming out of the north outfall (outfall 0040 to Burns Ditch/ Burns Waterway Harbor from US Steel’s Midwest Plant located at 6290 US-12, Portage, Porter County, IN 46368.  The orange material flowed into Burns Ditch/ Waterway and into Lake Michigan.   USEPA mobilized to the facility with START support to investigate the incident.  Response efforts were coordinated with the USCG and IDEM personnel.
