National Cement Co of California Inc - Cement Plant in Lebec, California

National Cement Co of California Inc operates a cement plant located in Lebec, California, United States. The facility is classified under NAICS code 327310 (Cement Manufacturing) and is currently operational. As a cement plant, it is part of the industrial utilities sector, producing cement for construction and infrastructure projects in the region. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), which enforces multi-media environmental regulations including the Clean Air Act (CAA), Clean Water Act (CWA), and Resource Conservation and Recovery Act (RCRA). Cement manufacturing is a significant source of air emissions, particularly particulate matter and greenhouse gases, and is subject to EPA's New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAP) for the cement sector. The facility's location in Lebec, near the Tejon Pass, places it in a rural area of Southern California. The plant's operations contribute to the local economy and construction supply chain, while its environmental impact is managed through state and federal permits. The site's proximity to the Los Angeles metropolitan area underscores its role in supplying cement to one of the largest construction markets in the United States.

The cement plant is located in a semi-arid region of Southern California, characterized by low rainfall and occasional drought conditions. Cement manufacturing is energy-intensive and generates significant CO2 emissions from both fuel combustion and the calcination process. The facility's emissions are regulated under the Clean Air Act, with specific limits on particulate matter, nitrogen oxides, and sulfur dioxide. The plant's proximity to the Angeles National Forest and sensitive ecosystems requires careful management of air and water discharges to minimize environmental impact.
