Electroplating Guidelines.pdf

The manual provides information to assist control authorities and approval authorities in implementing the National Categorical Pretreatment Standards for the electroplating and metal finishing point source categories.

The manual is divided into several sections, including an introduction, history of the electroplating and metal finishing categorical pretreatment standards, electroplating categorical pretreatment standards, metal finishing categorical pretreatment standards, treatment technologies, and requirements of the general pretreatment regulations.

The electroplating categorical pretreatment standards apply to facilities that perform electroplating operations, including job shops, captive shops, and independent shops. The standards establish limits for pollutants such as cadmium, chromium, copper, lead, nickel, and zinc. The manual also discusses exceptions from regulation coverage, pretreatment standards, pollutants excluded from regulation, and compliance dates.

The metal finishing categorical pretreatment standards apply to facilities that perform metal finishing operations, including electroplating, electroless plating, and other metal finishing processes. The standards establish limits for pollutants such as cadmium, chromium, copper, lead, nickel, and zinc, as well as cyanide and oil and grease. The manual also discusses exceptions from regulation coverage, pretreatment standards, pollutants excluded from regulation, and compliance dates.

The manual also discusses treatment technologies for common metals wastes, complexed metal wastes, precious metals wastes, hexavalent chromium, cyanide wastes, and oily wastes. It also discusses in-plant control of toxic organics, treatment of sludges, and in-process control technologies.

The requirements of the general pretreatment regulations are also discussed, including category determination requests, monitoring and reporting requirements, special industrial self-monitoring considerations, application of the combined wastestream formula, removal credits, fundamentally different factors variance, and local limits.

The manual includes several tables and figures, including a breakdown of the electroplating/metal finishing industry, pretreatment standards for existing sources, compliance dates for electroplating pretreatment standards, and metal finishing category unit operations.

Overall, the manual provides detailed information and guidance on the implementation of the electroplating and metal finishing categorical pretreatment standards, and is intended to be a useful tool for control authorities, approval authorities, and facilities subject to these regulations.
