Sec. 433.10  Applicability; description of the metal finishing point source category.


    (a) Except as noted in paragraphs (b) and (c), of this section, the 
provisions of this subpart apply to plants which perform any of the 
following six metal finishing operations on any basis material: 
Electroplating, Electroless Plating, Anodizing, Coating (chromating, 
phosphating, and coloring), Chemical Etching and Milling, and Printed
