CALPORTLAND CO CARMENITA TERMINAL Cement Plant in Santa Fe Springs, California

CALPORTLAND CO CARMENITA TERMINAL is a cement plant situated at 13846 Firestone Blvd in Santa Fe Springs, California, within Los Angeles County. As part of the CalPortland Company, this facility is a key player in the regional construction materials supply chain, providing cement for infrastructure and building projects. The plant operates under the NAICS code 327310, which classifies it as a cement manufacturing facility. The facility operates under the regulatory oversight of the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB), which enforce strict emissions standards under the Clean Air Act (CAA). Cement plants are subject to multi-media regulations including the Clean Water Act (CWA) for stormwater runoff and the Resource Conservation and Recovery Act (RCRA) for hazardous waste management. The plant likely employs modern dry-process kiln technology with baghouse filters and selective non-catalytic reduction (SNCR) to control nitrogen oxide emissions. Cement production is energy-intensive and generates significant CO2 emissions from both fuel combustion and the calcination of limestone. The plant's proximity to the Los Angeles metropolitan area means it plays a crucial role in supplying cement for urban development while operating under stringent local air quality management rules. Its operational status and location in a major industrial hub underscore its importance to the regional economy and infrastructure.

The facility is located in Santa Fe Springs, a densely populated area within Los Angeles County, which is designated as a severe nonattainment area for ozone and particulate matter under the Clean Air Act. Cement plants are significant sources of nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter, contributing to local air quality challenges. The plant's operations are subject to California's stringent greenhouse gas regulations, including the cap-and-trade program, and must comply with local air district rules such as South Coast Air Quality Management District (SCAQMD) Rule 1156 for cement kilns.
