USS Midwest Plant Back Up and Running After Wastewater Scare

Written by Michael Cowden

U.S. Steel’s Midwest Plant is back up and running after operations were temporarily halted because of discolored wastewater, a company spokeswoman said.

The Portage, Ind., finishing operation – part of U.S. Steel’s Gary Works in northwest Indiana – had been down for about a day, the spokeswoman told SMU on Wednesday afternoon.

US SteelMidwest Plant typically discharges treated wastewater into local waterways. But the discoloration became the subject of local media reports and resulted in beaches along the Indiana Dunes National Park being closed for swimming as a precaution.

U.S. Steel previously halted operations at Midwest Plant in April 2017 when a similar incident occurred, that one involving hexavalent chromium – a toxic chemical used in the tinning process. That was not the case this time. Testing indicates that chromium and hexavalent chromium levels were “well below” permitted levels, the spokeswoman said.

Midwest Plant makes tin mill products, cold-rolled coil, hot-dipped galvanized product, and electrical lamination steels. Its primary markets are automotive, construction, container and electrical markets, according to the company’s website
