UPDATE: Elevated levels of a highly toxic metal have triggered urgent violations against two foundries in southeast Los Angeles County. The South Coast Air Quality Management District (SCAQMD) confirmed that air samples collected from September 10-22, 2023, in Paramount revealed concerning levels of hexavalent chromium, a potent carcinogen linked to severe health risks.
The alarming findings, noted at a city-run monitoring station near Minnesota Avenue and Madison Street, prompted immediate investigations into local industrial facilities. On Friday, the SCAQMD announced that it had issued multiple air-quality violations to Pro Cast Industries, located directly across from the monitoring site, and Fenico, situated approximately 1,300 feet east of the station.
Hexavalent chromium, commonly utilized for its rust-resistant properties in auto parts and tools, is deemed 500 times more carcinogenic than diesel exhaust. Exposure to just 1 nanogram per cubic meter over 30 years corresponds to a cancer risk of 360 cases per million people, according to the California Air Resources Board. Recent samples from the monitoring station indicated levels ranging from 1.6 to nearly 2.2 nanograms per cubic meter, raising alarm among health officials.
Investigators discovered that both foundries failed to conduct mandatory tests for compliance with emission limits, neglected proper cleaning near chrome-alloy-melting facilities, and operated machinery without necessary permits. Additionally, Pro Cast was cited for utilizing more chromium-containing metals than authorized and for improper storage of chromium-laden scrap.
Representatives from both Pro Cast and Fenico have not responded to requests for comment. The SCAQMD is considering a settlement with the foundries, but if an agreement is not reached, financial penalties may be levied.
Mayor Peggy Lemons stated, “We’re working diligently to ensure the air in our city remains safe for all our residents. The South Coast AQMD has the expertise and enforcement tools to investigate and address these readings.” She emphasized the city’s commitment to community health and safety.
The backdrop of Paramount reveals a troubling history. The area, home to numerous metal-related businesses, has recorded some of the highest concentrations of hexavalent chromium in the state. Notably, in late October 2016, air sampling showed a spike of 26 nanograms per cubic meter. A community air monitoring network was initiated in 2013 following residents’ complaints about metallic odors, leading to investigations that have since reduced levels of toxic metals.
Despite these efforts, ongoing air sampling continues to indicate troubling concentrations of toxic substances, exacerbated by equipment malfunctions and regulatory noncompliance. As the situation develops, authorities urge residents to remain vigilant and informed.
The SCAQMD’s proactive measures and the community’s response will be critical as they navigate the path forward in ensuring air safety in Paramount. Further updates are expected as investigations continue and additional air quality data becomes available.
