A & A Ready Mixed Concrete Inc Cement Plant in Signal Hill, California

A & A Ready Mixed Concrete Inc is a cement plant located at 900 E Patterson in Signal Hill, California, within Los Angeles County. The facility is operational and falls under NAICS codes 327310 (Cement Manufacturing) and 327320 (Ready-Mix Concrete Manufacturing), indicating its role in producing cement and concrete products for regional construction. As a cement plant in California, the facility operates under the regulatory oversight of the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). It must comply with the Clean Air Act (CAA) for emissions of particulate matter, nitrogen oxides, and sulfur dioxide, as well as the Clean Water Act (CWA) for stormwater runoff. The plant likely uses dry or wet kiln processes, with typical capacities ranging from small to medium scale for the region. The plant's location in Signal Hill, near Long Beach, places it in a densely populated urban area with significant industrial activity. Its proximity to residential communities necessitates strict adherence to air quality regulations and community right-to-know reporting under the Emergency Planning and Community Right-to-Know Act (EPCRA). The facility contributes to local infrastructure development but also faces environmental scrutiny typical of the cement sector.

Signal Hill is located in the South Coast Air Basin, an area with persistent air quality challenges due to industrial emissions and vehicle traffic. Cement plants in this region are significant sources of particulate matter and greenhouse gases, requiring compliance with stringent CARB rules. The facility's proximity to residential neighborhoods increases community exposure to potential pollutants, making local air monitoring and pollution control technologies critical for minimizing health impacts.
