chrome -- Advisory for Chrome Plating and Anodizing Facilities using Chemical Fume Suppressants Posted: 24 Aug 2016 10:40:51
The California Air Resources Board (ARB) has issued an advisory regarding the use of chemical fume suppressants containing perfluorinated octane sulfonate (PFOS). On September 19, 2012, the United States Environmental Protection Agency (U.S. EPA) published final amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAPs) – Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks. Effective September 21, 2015, the NESHAP bans PFOS-based fume suppressants for use in chrome plating operations. However, ARB granted facilities a one year extension from this ban to allow for the time needed to certify new non PFOS fume suppressants. Once this extension ends on September 21, 2016, the owner or operator of a hard chrome plating, decorative chrome plating, or chromic acid anodizing tank, including enclosed tanks and trivalent chromium tanks, may not add PFOS-based fume suppressants to any electroplating tank. For more information on complying with the NESHAP, please see the advisory posted at: http://www.arb.ca.gov/toxics/chrome/pfosadvisoryfinalaug2016.pdf Information on the Chrome ATCM and additional information on fume suppressants can be found on our website at http://www.arb.ca.gov/toxics/chrome/chrome.htm. For facilities that are required to use a certified fume suppressant, the list of certified fume suppressants can be found here: http://www.arb.ca.gov/toxics/chrome/fumesuppresslist0416.pdf. This list will be updated as new products become certified or if surface tensions are revised for fume suppressants. If you have questions regarding chrome plating operations outside of the South Coast Air Quality Management District (SCAQMD), please contact Michelle Komlenic, Air Pollution Specialist, at (916) 322-3926 or via email at firstname.lastname@example.org. Facilities located within the SCAQMD should contact Mitch Haimov, Senior Engineering Manager, at (909) 396-3129 or via email at email@example.com. Background: Facilities in California are subject to the Chrome ATCM. Many of California’s facilities are required to use a certified fume suppressant to meet hexavalent chrome emission limits. Facilities located in the SCAQMD are subject to Rule 1469 which states that only ARB/SCAQMD certified non-PFOS fume suppressants will be allowed to be used by chrome plating/anodizing facilities. California maintains a list of certified fume suppressants which have undergone testing to meet hexavalent chromium emission standards. Currently, ARB has certified three non-PFOS fume suppressants for use in chrome plating operations, and is continuing to work with non-PFOS fume suppressant manufacturers to test and certify additional products. SCAQMD is in the process of completing its certification of these products. California is in a drought emergency. Visit www.SaveOurH2O.org for water conservation tips.
