Waste Designation Decision Matrix - Advanced Topics
Although the Matrix is relatively comprehensive of the rules that govern whether or not a waste is hazardous or not, there are complicated concepts, exceptions, and policies that could affect your waste classification. Review the following information to determine if any of these concepts, exceptions, and policies apply to your waste.
- "Contained-In" Policy/Rule
- "Mixture Rule"
- Underlying Hazardous Constituents
- "Derived-from" Rule
- Universal Wastes
- Land Restrictions
Unfortunately, all the aforementioned rules and policies are often subject to interpretation. When attempting to apply these topics, please contact the TCEQ.
