CALPORTLAND - NATIONAL CITY Cement Plant, National City, California | Industrial Utilities

CALPORTLAND - NATIONAL CITY is a cement plant located at 920 Bay Marina Dr, National City, California, in San Diego County. The facility operates 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 US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) for emissions, the Clean Water Act (CWA) for water discharges, and Resource Conservation and Recovery Act (RCRA) for waste management. Cement plants are subject to National Emission Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS). The facility likely uses dry or wet kiln processes, with typical production capacities ranging from medium to large scale. Cement production is energy-intensive and generates significant CO2 emissions, as well as particulate matter and other pollutants. The plant's proximity to San Diego Bay and urban areas necessitates strict environmental controls. Its role in providing essential construction materials supports local economic development, but also requires ongoing compliance with environmental regulations to minimize community and ecological impact.

The plant is situated in National City, part of the San Diego metropolitan area, near San Diego Bay. This coastal location means the facility must manage air emissions and stormwater runoff to protect local air quality and marine ecosystems. Cement production involves high-temperature kilns that emit CO2, NOx, SO2, and particulate matter. The plant operates under California's stringent environmental regulations, which include the California Environmental Quality Act (CEQA) and local air district rules. Community proximity raises concerns about dust and traffic, requiring effective mitigation measures.
