Mitsubishi Cement Co is a cement manufacturing facility located at 5808 Hwy 18 in Lucerne Valley, San Bernardino County, California. The plant is operational and falls under NAICS codes 212312 for limestone mining and 327310 for cement manufacturing, indicating an integrated operation from raw material extraction to clinker production. The facility operates under the regulatory framework of the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). Cement plants are subject to Clean Air Act (CAA) standards for particulate matter, nitrogen oxides, and sulfur dioxide, as well as Clean Water Act (CWA) requirements for process water discharge. The plant likely holds Title V operating permits and must comply with National Emission Standards for Hazardous Air Pollutants (NESHAP) for the cement sector. As a major cement producer in the region, Mitsubishi Cement Co serves construction markets across Southern California and the southwestern United States. The plant's location in the Mojave Desert presents unique environmental considerations, including water scarcity and dust management. Its integrated mining and manufacturing operations contribute to the local economy while requiring robust environmental controls.
Environmental context
Located in the Mojave Desert near Lucerne Valley, the plant operates in an arid region with sensitive ecosystems. Cement manufacturing is a significant source of greenhouse gas emissions (CO2 from calcination) and criteria air pollutants. The facility's proximity to rural communities and Joshua Tree National Park (approximately 20 miles south) necessitates stringent air quality management. Water use for cooling and dust suppression is a concern in this water-scarce area, and the plant must comply with California's strict water regulations.
