What are the major generator categories under RCRA and what defines a 'hazardous waste'?

• A. Very Small Quantity Generator (VSQG), Small Quantity Generator (SQG), Large Quantity Generator (LQG); hazardous waste is defined by listed or characteristic hazardous waste traits.
• B. Minor Generator, Medium Generator, Major Generator; hazardous waste defined by color.
• C. Very Small Generator, Small Generator, Large Generator; hazardous waste defined by volume.
• D. Very Small Quantity Generator (VSQG), Large Quantity Generator (LQG), Very Large Generator (VLG); hazardous waste defined by listed or characteristic traits.

Answer: (A)

The main idea being tested is how RCRA groups generators and defines what counts as hazardous waste. Under RCRA, facilities are categorized based on how much hazardous waste they generate in a calendar month, using three generator types: Very Small Quantity Generator, Small Quantity Generator, and Large Quantity Generator. This classification is strictly about quantity, not about color, volume in storage, or any qualitative attribute of the waste. Hazardous waste itself is defined in two ways: wastes that are listed on specific hazardous-waste lists, and wastes that exhibit one or more hazardous characteristics—ignitability, corrosivity, reactivity, or toxicity (the toxicity characteristic is determined by testing, often via TCLP). So the correct choice reflects both the generator categories (Very Small Quantity Generator, Small Quantity Generator, Large Quantity Generator) and the definition of hazardous waste as either listed or characteristic. The other options misstate either the generator categories or the basis for hazardous-waste definitions (using non-existent categories like Minor or Major, or using color or volume, which aren’t how RCRA classifies hazardous waste).
