Rule
1469, as amended May 2, 2003, requires the owner or operator of a chrome
plating or chromic acid anodizing tank currently using a wetting agent fume
suppressant to begin using a wetting-agent fume suppressant certified by
AQMD. This requirement becomes effective on May 2, 2004. This is
only one of several requirements facilities must comply with in Rule 1469.
Certification requires that the fume suppressant be able to reduce or
suppress hexavalent chromium 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 per ampere hour is
achieved.
The
following list of certified fume suppressants have all been tested and
determined to meet an emission limitation of 0.01 milligrams of Cr+6/ampere-hour
of applied current at the stated surface tension.

DISCLAIMER: All wetting-agent fume suppressant products included in this
list are certified 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 maximum level listed
under “Usage Restrictions” in the table and while following manufacturers'
usage directions. SCAQMD Rule 1469(c)(3) requires
the use of certified wetting-agent chemical fume suppressants as of May 2,
2004. SCAQMD in no way endorses any of these products. This list is
arranged alphabetically. Source test results used to develop the maximum
surface tensions listed under “Usage Restrictions” in this table are limited
to certification of wetting-agent chemical fume suppressants only and should
not be used for other purposes. |
