Frequent Questions

Does the F006 listing apply to copper electroplating?

Yes, the F006 listing applies to wastewater sludges from copper electroplating operations. Excluded from this listing are certain processes, such as: 

(1) sulfuric acid anodizing of aluminum;
(2) tin plating on carbon steel; 
(3) zinc plating (segregated basis) on carbon steel;
(4) aluminum or zinc-aluminum plating on carbon steel; 
(5) cleaning/stripping associated with tin, zinc, and aluminum plating on carbon steel; and
 (6) chemical etching and milling of aluminum (40 CFR §261.31(a)).
 
Only those wastewater sludges from electroplating operations that are specifically excluded are not subject to regulation as F006.
