Steel Dynamics Inc. - Primary Metal Facility in Pittsboro, Indiana

Steel Dynamics Inc. (SDI) operates a primary metal facility at 8000 North County Road 225 East in Pittsboro, Indiana. This plant is part of one of the largest steel producers in the United States, specializing in electric arc furnace (EAF) steelmaking, which uses recycled scrap metal as feedstock. The facility is operational and contributes to the regional industrial base in central Indiana. The plant operates under the NAICS code 331111 (Iron and Steel Mills) and is subject to U.S. EPA regulations including the Clean Air Act (CAA), Clean Water Act (CWA), and Resource Conservation and Recovery Act (RCRA). As an EAF facility, it typically has lower carbon emissions compared to integrated blast furnace operations but still manages significant air emissions (e.g., particulate matter, nitrogen oxides) and solid waste (e.g., slag, dust). The facility likely holds a Title V air permit and a National Pollutant Discharge Elimination System (NPDES) permit for water discharges. Steel Dynamics is a major player in the U.S. steel industry, with a focus on recycling and sustainable production. This Pittsboro plant supports local employment and the broader manufacturing supply chain. The facility's environmental footprint is managed through regulatory compliance and industry best practices, including dust control and wastewater treatment.

The plant is located in Pittsboro, Indiana, a rural area with nearby residential communities. Steel production via EAF generates air emissions such as particulate matter and heavy metals, which require stringent control under the Clean Air Act. Water usage for cooling and process needs is regulated under the Clean Water Act, with discharge permits limiting pollutants. The facility also manages hazardous wastes like spent refractories and dust under RCRA. Proximity to communities necessitates careful monitoring of fugitive emissions and noise.
