Large quantity generators are defined as those facilities that generate:

• A. 1 kg of acutely hazardous waste per calendar month
• B. 1 kg of acutely hazardous waste per calendar year
• C. 1 lb of acutely hazardous waste per calendar month
• D. 1 lb of acutely hazardous waste per calendar year

Answer: (A)

The key idea is that the generator status for acutely hazardous waste hinges on monthly quantity. For wastes that are acutely hazardous (the P- and U-lists), generating about 1 kilogram or more in a month triggers the stricter generator requirements associated with large quantity generators for those wastes. That’s why the option describing 1 kilogram per calendar month best matches how acutely hazardous waste influences generator classification. The other choices mix units (pounds instead of kilograms) or time frames (per year), or imply a threshold that’s not the regulatory trigger for acutely hazardous waste.
