Rule
1469 requires the owner or operator of a chromium electroplating or chromic acid anodizing tank currently using a wetting agent fume
suppressant to use a California Air Resources Board (CARB) certified
chemical fume suppressant.
Certification requires that the fume suppressant be able to reduce or
suppress hexavalent chromium (Cr+6) emissions at the surface of an electroplating
or anodizing bath through the reduction of surface tension of the bath to a
level at which an emission factor of 0.01 milligrams of Cr+6/ampere-hour is
achieved.
The
following list of certified fume suppressants have all been tested and
certified by CARB to meet an emission limitation of 0.01 milligrams of Cr+6/ampere-hour
of applied current at the stated surface tension.

CARB to
meet the rule limit. Contact Carla Takemoto of CARB at (916) 324-8028 for more information on product testing
and certification.
DISCLAIMER: All wetting-agent fume suppressant products included in this
list are certified by CARB as able to meet an emission limitation of 0.01 milligrams
of hexavalent chromium per ampere-hour of applied current, by reducing the
surface tension of hexavalent chromium electroplating or chromic acid
anodizing baths, provided they are used in sufficient quantity to reduce the
surface tension of the plating or anodizing bath to the value listed in the table
in addition to following manufacturers' usage directions. The list is
arranged alphabetically and the AQMD in no way endorses any of these
products. Source test results used to develop the maximum
surface tensions listed in this table are limited
to certification of wetting-agent chemical fume suppressants only and should
not be used for other purposes. |
