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 specializing in steel production. As an integrated steel mill, it encompasses coke ovens, blast furnaces, and basic oxygen furnaces, making it one of the largest and most significant steel plants in the country. The facility operates under the regulatory oversight of the US Environmental Protection Agency (EPA), with permits covering air emissions (Clean Air Act), water discharges (Clean Water Act), and waste management (Resource Conservation and Recovery Act). Steel production at this scale involves energy-intensive processes that generate significant emissions, including carbon dioxide, particulate matter, and sulfur dioxide. The facility's NAICS code 331111 indicates it is a steel mill with integrated operations, typically involving iron ore reduction and steel refining. The Gary Complex is situated on the southern shore of Lake Michigan, which provides access to water transportation and cooling water, but also raises environmental considerations regarding water use and thermal discharges. The Gary Complex plays a critical role in the regional economy, providing thousands of jobs and supplying steel for automotive, construction, and industrial applications. Its environmental significance stems from its large-scale emissions and proximity to the Great Lakes ecosystem. The facility is subject to EPA's multi-media regulatory framework, including TRI Section 313 reporting for toxic chemical releases, and must comply with stringent air and water quality standards.

Located in Gary, Indiana, along the southern shore of Lake Michigan, the facility operates in an area with significant industrial history.
