QUESTIONS
1. What is the top priority for hazardous waste management (general method) under
RCRA? What is the lowest priority?
2. Which of the following under RCRA is (are) not excluded from the rules and regulations
applicable to hazardous waste generators, treatment, storage, disposal, and transporta-
tion? (a) domestic sewage; (b) spent nuclear or by-product material; (c) household waste;
(d) spent halogenated solvents.
3. What are acute hazardous wastes? Provide an accurate technical definition.
4. Which of the following property(ies) is (are) not characteristics that define a RCRA haz-
ardous waste? (a) radioactive; (b) corrosive; (c) ignitable; (d) reactive; (e) biohazard.
5. What pH range does noncorrosive waste display?
6. What is the name of the test method used to determine if a waste is toxic? Describe the
details of the method.
7. Can a generator legally mix a listed hazardous waste with sufficient nonhazardous solid
waste to the point where it can be diluted and therefore is no longer classified as a haz-
ardous waste? Discuss.
