South Shore Slag LLC - Contractor of USS Gary Works (00121) is a primary metal facility located at 1 N Buchanan St, Gary, Indiana, in Lake County. As a contractor for the USS Gary Works steel mill, it processes slag generated from steelmaking, operating under NAICS codes 327992 (ground or treated mineral and earth manufacturing) and 331111 (iron and steel mills). The facility is operational and situated in the industrial corridor of Gary, a key region for steel production in the United States. The facility operates under the regulatory framework of the US Environmental Protection Agency (EPA), including 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 operation, it is subject to emissions limits for particulate matter, sulfur dioxide, and nitrogen oxides, as well as wastewater discharge permits for process water. The plant's scale is typical for a slag processing contractor serving a large integrated steel mill, with moderate throughput. Environmentally, the facility's role in recycling slag reduces waste sent to landfills and provides raw materials for construction and agriculture. However, primary metal operations carry inherent risks of air emissions and heavy metal releases. The plant's proximity to the Grand Calumet River and Lake Michigan underscores the importance of compliance with water quality standards. Its location in a densely industrialized area of Gary highlights the need for robust environmental management and community engagement.
Environmental context
The facility is located in Gary, Indiana, within the heavily industrialized Calumet region, which has a history of steel production and associated environmental impacts. Primary metal operations like slag processing can release particulate matter, heavy metals, and sulfur compounds into the air, while stormwater runoff may carry pollutants to nearby waterways such as the Grand Calumet River and Lake Michigan. The area's industrial legacy has led to soil and water contamination, making regulatory compliance under the Clean Water Act and Resource Conservation and Recovery Act critical for protecting local ecosystems and community health.
