386 Waste Management Practices: Municipal, Hazardous, and Industrial
8. The Hi-Jinx Metalworks Corp. has produced several gallons of a spent paint stripper.
Based solely on the Material Safety Data Sheet (following pages), could this waste be a
RCRA hazardous waste?
9. Outside one of the Hi-Jinx warehouses (which has stored paint stripper in the past),
several drums are discovered and there is a sweet solvent odor. Is the contaminated soil
considered a hazardous waste? Explain.
10. The environmental safety officer at the Hi-Jinx plant identifies dozens of drums contain-
ing a reddish filter cake near the site’s electroplating wastewater treatment plant. After
analyzing the filter cake, the level of chromium in the sludge is determined to be 75
mg/kg and the TCLP test measures 2 mg/L in the resulting leachate. What can the facil-
ity conclude regarding the waste and its proper management?
11. Can a waste be both a listed hazardous waste and a characteristic hazardous waste? Explain.
12. An automobile body shop and painting facility is in operation. Metal parts are reworked
and repainted; engine components are cleaned and reworked; fiberglass and metal body
parts are repaired, replaced, and painted. List at least ten different types of waste gener-
ated at the facility. Separate into solid (nonhazardous) and hazardous (listed and charac-
teristic) wastes.
13. List potential sources of hazardous waste generated in your university. Name any listed
hazardous wastes. To what list(s) do they belong? If not listed, what are the specific char-
acteristics that render these wastes hazardous?
14. Write in the name of each list on the table below:
