The treatment standard for the high-mercury subcategory that applied at the point of generation must be met at the point of disposal, regardless of the reduction of mercury content in the waste during treatment for another hazardous constituent. The generator of a waste must determine at the point of generation all applicable waste codes and treatment standards subcategories. These determinations apply throughout the life of the waste. All applicable waste codes must be determined at the point of generation so as to prevent the generator from diluting the waste to circumvent an applicable treatment standard (51 FR 40572, 40260; November 7, 1986).
