Which CFR Part addresses metal finishing prior to 1985?

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

Answer: (A)

The key idea here is how the EPA organized effluent guidelines by industry and by time period. The regulation that set the pretreatment and discharge limits for metal finishing in its earlier form—before the 1985 updates—is the one that corresponds to metal finishing prior to that year. It establishes the baseline limits and requirements that metal finishing facilities had to meet before the newer revisions took effect. The other parts cover different industries or post-1985 amendments, so they don’t describe the pre-1985 metal finishing standards.
