ArcelorMittal Indiana Harbor - Primary Metal Facility in East Chicago, Indiana

ArcelorMittal Indiana Harbor, located at 3001 Dickey Road in East Chicago, Indiana, is a large-scale primary metal facility specializing in steel production. The plant is operational and represents a significant industrial presence in the Great Lakes region, with a NAICS code of 331111 (Iron and Steel Mills). The facility operates under the comprehensive regulatory framework of the United States Environmental Protection Agency (EPA), which includes the Clean Air Act (CAA), Clean Water Act (CWA), Resource Conservation and Recovery Act (RCRA), and Toxics Release Inventory (TRI) Section 313 reporting. As a primary metal plant, it is subject to stringent emissions limits and waste management requirements typical of the steel sector. This facility plays a critical role in the regional industrial supply chain, producing steel for construction, automotive, and manufacturing sectors. Its location near Lake Michigan and major transportation routes underscores its logistical importance, while its scale and production processes necessitate robust environmental management to mitigate impacts on air and water quality.

The East Chicago area is part of the heavily industrialized Calumet region, with a history of steel production and refining. The facility's proximity to Lake Michigan and residential communities raises concerns about air emissions (particulates, sulfur dioxide) and water discharges. Regulatory oversight under the CWA and CAA is critical to managing these impacts, with TRI reporting providing transparency on chemical releases.
