Ash Grove Cement South Texas LLC - Cement Plant in New Braunfels, Texas

Ash Grove Cement South Texas LLC is a cement manufacturing facility located in New Braunfels, Comal County, Texas. The plant is operational and produces cement, lime, and related construction materials. As a cement plant, it falls under the industrial utilities sector, with NAICS codes covering crushed stone mining, cement manufacturing, and concrete product production. The facility operates under the regulatory framework of the U.S. 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. Cement plants are subject to stringent emissions standards for particulate matter, nitrogen oxides, and sulfur dioxide. The plant's location in Texas places it under the jurisdiction of the Texas Commission on Environmental Quality (TCEQ) for state-level permitting and compliance. Cement production is energy-intensive and generates significant CO2 emissions from both fuel combustion and the calcination process. The plant's proximity to the growing San Antonio-Austin corridor means it plays a key role in supplying construction materials to a rapidly urbanizing region. Environmental management practices typically include baghouse filters, continuous emissions monitoring, and water recycling systems to minimize environmental impact.

The plant is situated in Comal County, Texas, near the Guadalupe River and the Edwards Aquifer recharge zone. Cement production can generate dust, air emissions, and process water discharges that require careful management to protect local water resources and air quality. The region's karst geology makes groundwater particularly vulnerable to contamination, necessitating robust environmental controls.
