Southern California Platers Search for PFOS Alternatives

SCAQMD, the air pollution control agency for Orange County and the urban portions of Los Angeles, Riverside and San Bernardino counties, requires platers to use a SCAQMD-certified chemical fume suppressant.

Electroplating shops in southern California can no longer add perfluorooctanesulfonic (PFOS) acid fume suppressants to the tanks of their chromic acid anodizing and hard or decorative chrome plating lines.

Beginning in late September, the South Coast Air Quality Management District (SCAQMD)—the air pollution control agency for Orange County and the urban portions of Los Angeles, Riverside and San Bernardino counties—requires platers to use a SCAQMD-certified chemical fume suppressant.

The certification requires that the fume suppressant must reduce or suppress hexavalent chromium emissions at the surface of a bath by reducing its surface tension.

Officials from the Metal Finishers Association of Southern California, however, say that some OEMs may object to the non-PFOS products. 

They say that Boeing and other primes have indicated they will not approve the use of non-PFOS products, which means those shops would have to use other controls to meet the emission limit.
