This approach is a risk-based approach that focuses on the total quantities of key chemicals in a waste each calendar year. This approach is more flexible and less burdensome for the waste generator, yet still protective of human health and the environment.
The annual mass loading levels (regulatory levels) for the constituents of concern in the wastes are identified. All wastes which contain constituents of concern below these regulatory levels may be managed as nonhazardous during the year. The loading limits serve as very clear pollution prevention goals for those generators that may produce wastes with elevated levels of the K181 constituents.
Why is a mass loadings-based approach being used for the dyes and pigments listing?
