Chrome plating businesses in California are subject to the Chrome Airborne Toxic Control Measures (ATCM). Many facilities are required to use a certified fume suppressant to meet hexavalent chrome emission limits. Local air districts have developed rules to implement these requirements. Chrome plating facilities in South Coast Air Quality Management District (SCAQMD) are subject to Rule 1469. Rule 1469 requires that only California Air Resources Board (ARB)/SCAQMD certified non-perfluorooctane sulfonic acid (PFOS) fume suppressants will be allowed to be used by chrome plating/anodizing facilities. ARB maintains a list of certified fume suppressants which meets hexavalent chromium emission standards.
ARB has updated the list of non-PFOS based chemical fume suppressants which are used in specific chrome plate operations. On September 19, 2012, the US EPA published final updates to the National Emission Standards for Hazardous Air Pollutants (NESHAPs) – Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks. The updated provisions in NESHAP banned PFOS based fume suppressants for use in chrome plating operations effective since September 21, 2015. However, ARB granted chrome plating businesses a one year extension. This extension ended on September 21, 2016. After this date, no owner or operator of a hard chrome plating, decorative chrome plating, or chromic acid anodizing tank, including enclosed tanks and trivalent chromium tanks, is allowed to add PFOS based fume suppressants to any electroplating tank. Facilities which are subject to certified fume Suppressant requirements, the updated list of certified fume suppressants can be found here.
This list will be updated by ARB as new products become certified. Information on the Chrome ATCM and additional information on fume suppressants can be found on ARB's website here.
