It appears the EPA is concerned with regulating Chromic Anodizing (chromic acid is used instead of sulfuric acid in some types of anodizing.) Fumes and vapors containing chromic acid form a dust when dried, and cause airborne hazards. I haven't found anything to indicate sulfuric acid is regulated in small quantities, whether it's business use or not. Though chromic and sulfuric acids are in two different categories, I still believe sulfuric acid should be handled and disposed of with due concern and responsibility.
This is only from research I have done on the Internet; so don't take it as gospel. You should do some personal searching on the internet if you haven't already, perhaps using the search phrase "government anodizing regulations", or "anodizing regulations", and see what's out there.
