Hazardous Waste Determination - Oregon State University
You have a solid waste that you want to discard or is no longer useful. Is it hazardous?

You will need to ask yourself is it “hazardous” in order to determine how to properly dispose of the material. This process is called a “waste determination”. Waste determinations can be conducted using one of two methods: 1) Sampling and analysis or 2) Using generator knowledge. The below process applies to method #2: After completing the waste determination, complete a waste label and affix to the container.

1. Is the "solid waste" excluded from the definition of a hazardous waste? Check exclusion list. YES - waste is NOT hazardous
NO - go to step 2
2. Is the material on the K, F, P, or U lists? Check lists or run Report from online chemical inventory program. YES - waste IS hazardous
NO - go to step 3
3. Does the waste exhibit one or more characteristic hazards? Check D-list or run Report from online chemical inventory program. YES - waste IS hazardous
No - go to step 4
4. Waste is not hazardous by state/federal hazardous waste regulations, but may be hazardous by local or OSU rules.
5. If you have a process that generates waste, we can help with your waste determination.
