US Steel Gary Complex - Primary Metal Facility in Gary, Indiana

The US Steel Gary Complex, located at 1 North Broadway in Gary, Indiana, is a major primary metal facility in the United States. As an integrated steel mill, it operates under the NAICS code 331111, indicating iron and steel production. The plant is operational and plays a key role in the regional industrial landscape. This facility operates under the US EPA's multi-media regulatory framework, including the Clean Air Act (CAA), Clean Water Act (CWA), Resource Conservation and Recovery Act (RCRA), and Toxic Release Inventory (TRI) Section 313 reporting. As a large-scale steel producer, it is subject to stringent emissions standards and waste management requirements. The plant's location in Gary, Indiana, places it within the Great Lakes industrial corridor, a region with a dense concentration of heavy industry. The environmental significance of the US Steel Gary Complex is tied to its scale and the inherent pollution intensity of primary metal production. Steel manufacturing involves high energy consumption, emissions of particulate matter and greenhouse gases, and generation of industrial waste. The facility's proximity to Lake Michigan and urban communities necessitates robust environmental management and community engagement.

The Gary area is part of the Great Lakes Basin, a region with significant industrial history and environmental sensitivity. Primary metal facilities like this one are major sources of air emissions (e.g., sulfur dioxide, nitrogen oxides, particulate matter) and water discharges. The plant's location near Lake Michigan requires compliance with the Clean Water Act's effluent guidelines for the iron and steel sector. Community proximity to the facility raises concerns about local air quality and potential health impacts, driving regulatory oversight and community right-to-know programs under TRI.
