U.S. Steel Gary Works Air Permit Factsheet

US Steel's Gary Works facility is Indiana's single largest source of carbon emissions and heavy metal pollution. IDEM must strengthen the facility's air permit.

U.S. Steel Gary Works in Gary, Indiana is the largest integrated steel mill in the United States and spans 4,000 acres along Lake Michigan nearby Indiana Dunes National Park.

The Indiana Department of Environmental Management (IDEM) issued a draft renewal of U.S. Steel’s Title V air permit in February and in response to public requests, is hosting a public hearing on the draft permit on April 25, 2024 at 6 PM.

IDEM has also extended the public comment deadline to April 29, 2024.

Public attendance at the hearing is important as it gives speakers an opportunity to have their voices and lived experiences heard by IDEM and incorporated into the public record. Because this is a hearing and not a meeting, IDEM will not answer any questions in person. However, they will respond to questions in writing in an addendum to the final permit.

The Environmental Integrity Project (EIP) and Environmental Law & Policy Center (ELPC) reviewed the draft permit and identified numerous defects, summarized below. We will submit these issues as written comments as well.
