USG Structural Technologies LLC Cement Plant, Delavan, Wisconsin | Industrial Utilities

USG Structural Technologies LLC is a cement plant located at 309 Hallberg St, Delavan, Wisconsin, in Walworth County. The facility is operational and falls under NAICS codes 327310 (Cement Manufacturing) and 327420 (Gypsum Product Manufacturing). As a cement plant, it is part of a sector known for high energy consumption and significant emissions of CO2, NOx, and particulate matter. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), which enforces the Clean Air Act (CAA), Clean Water Act (CWA), Resource Conservation and Recovery Act (RCRA), and Toxics Release Inventory (TRI) reporting. Cement plants in the U.S. are subject to National Emission Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS). The plant's scale is typical for a mid-sized cement facility, with processes including raw material grinding, clinker production, and finish milling. Cement plants are significant contributors to local economies but also pose environmental challenges due to dust, greenhouse gas emissions, and water use. The Delavan facility's proximity to residential areas may require careful management of air quality and noise. Its operational status indicates ongoing compliance with state and federal permits.

The cement sector is inherently pollution-intensive, with primary emissions including carbon dioxide (CO2) from calcination and fuel combustion, nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter. Water use for cooling and dust suppression can impact local water resources. In Wisconsin, cement plants must comply with state air permits and EPA regulations. Community proximity in Delavan may raise concerns about air quality and truck traffic, necessitating robust environmental management systems.
