Hazardous Waste Generator Requirements 415
11. Large quantity generators must have double liners on all new containers for hazardous
wastes stored on-site (true or false).
12. Which of the following are acceptable management practices for a satellite accumulation
area? (a) stores a maximum of 55 gal of hazardous waste; (b) stores a maximum of 1
quart of acute hazardous waste; (c) it is under the continuous control of the personnel
who generate the wastes
13. What are the requirements for an acceptable container being used in a satellite accumu-
lation area?
14. As a result of a new manufacturing process, the Hi-Jinx Chemical Company is generat-
ing a new waste stream. The waste has the following properties: pH 10; flashpoint
75°F; high concentrations of Cd and Cr (exceeds TCLP limits); approximately 2500
lb/month. Based on the waste alone, is the generator a LQG, SQG, or CESQG? Must the
generator comply with DOT regulations for packaging the wastes and placarding the
vehicles? For how long can the generator stockpile waste on-site without a permit? Is
there a requirement for the submission of a written emergency response plan to the state
environmental agency?
15. Based on question 14, is the waste to be classified as corrosive, ignitable, or toxic?
16. Based on the waste properties given in question 14, can the waste be stored in a single-lined
tank on the premises? How far must it be stored from the property line? To what type of
facility (e.g., state-approved, EPA-approved) must the waste be shipped for final disposal?
17. If the waste in question 14 could be recycled into another process at another facility, must
it be considered a RCRA “hazardous waste”?
18. The waste in question 14 may possibly serve as a boiler fuel and therefore need not be
managed as a waste at all (true or false).
19. At Bogus Metalworks, hazardous liquid wastes were recycled in a second process. The
2500 lb. of waste liquid produced were sent to a machine degreasing booth and reused a
total of four times in September. How much waste must be counted at the end of the month?
20. At the Hi-Jinx facility, pentachlorophenol, a listed hazardous waste, was mixed with clean
soil during a small spill. Is the new mixture still a hazardous waste? Justify your answer.
21. Also at the Hi-Jinx plant, the tops of several drums of the pentachlorophenol are dam-
aged and severely rusting. Since wastes are not leaking, can they remain in these con-
tainers until they are to be transported?
22. In what specific ways are individual households subject to the requirements of RCRA?
23. According to U.S. EPA regulations, when must a hazardous waste manifest copy with an
original signature of the TSD facility representative be received by the generator?
24. For how long do RCRA regulations require that manifests be retained?
25. List and discuss what is incorrect about the Uniform Hazardous Waste Manifest shown
in Figure 12.6.
26. If the signed return copy (closed copy) of a manifest is not received by a large quantity
generator within 35 days, an investigation must be conducted to locate the return copy.
When must exception reports be submitted to the state?
27. If a small quantity generator does not receive a return copy of the manifest within 60
days, what action is required?
For some of the following questions, it may be useful to refer to 40 CFR 262, Generator
Requirements.
28. A generator of hazardous waste determines that more than 100 kg of waste will be gen-
erated in a calendar month. What documentation/identification, etc., must they obtain?
29. What is the maximum quantity of hazardous waste that can be accumulated in a satellite
accumulation point?
30. Accumulation points for containers must be inspected weekly. What should be inspected?
31. How frequently should hazardous waste storage tanks be inspected?
