In December, the South Coast Air Quality Management District (SCAQMD) took 13 samples from the roof of the Anaplex facility, which revealed a wide range of hexavalent chromium deposits ranging up to 75,000 ppm. Although this number reflects a different type of measurement than what is used for air quality monitoring, the numbers were viewed as significant. Anaplex had reported cleaning its roof after SCAQMD’s inspection, though before the rainfall that had occurred the following weekend.
The Health Hazardous Materials Division of the Los Angeles County Fire Department investigated Anaplex’s cleaning methods and procedures at the beginning of January. The Division protects the public health and the environment from accidental releases and improper handling or disposal of hazardous materials and wastes. After a thorough inspection on January 4, the Fire Department’s inspectors did not observe any violations. Under the abatement order, Anaplex must continue to prevent future releases of hexavalent chromium to the environment by complying with all SCAQMD air pollution control measures.
The City continues to work with the Fire Department’s Health Hazardous Materials Division, SCAQMD, and other regulatory agencies to monitor both verified and potential sources of hexavalent chromium in order to ensure public health and safety.
