CEMEX Construction Materials South, LLC Cement Plant in New Braunfels, Texas

CEMEX Construction Materials South, LLC is a cement plant located at 2580 Wald Road in New Braunfels, Comal County, Texas. As part of the global CEMEX group, this facility plays a key role in supplying cement and construction materials to the local and regional market. The plant is operational and classified under NAICS codes 212312 (crushed and broken limestone mining), 236210 (industrial building construction), and 327310 (cement manufacturing). The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA), which includes 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 specific emissions standards for particulate matter, nitrogen oxides, and sulfur dioxide, as well as requirements for managing hazardous waste and stormwater runoff. Cement production is energy-intensive and generates significant CO2 emissions from both fuel combustion and the calcination of limestone. The plant's location in Comal County places it in a region with growing urban development, where its operations contribute to local infrastructure but also require careful environmental management to minimize impacts on air quality and water resources.

The cement plant is situated in Comal County, Texas, an area characterized by karst topography and the Edwards Aquifer, a critical water source. Cement manufacturing involves quarrying, crushing, and high-temperature kiln operations, which can generate dust, emissions of nitrogen oxides and sulfur dioxide, and greenhouse gases. Proximity to residential areas in New Braunfels necessitates robust emission controls and community engagement to address air quality concerns.
