Which CFR Part addresses metal finishing after 1985?

• A. Part 413
• B. Part 433
• C. Part 437
• D. Part 435

Answer: (B)

The question tests knowledge of which regulatory section specifically governs metal finishing discharges under the pretreatment program. Part 433 was created to address the electroplating and metal finishing category, setting the categorical pretreatment standards, discharge limits for metals (and related pollutants), and requirements for monitoring and reporting for those operations. This focus on metal finishing after 1985 is why this Part is the correct reference. The other Parts apply to different industries or regulatory contexts and do not target metal finishing in the same way.
