What is the time limit for Large Quantity Generators?

• A. ≤270 days
• B. ≤180 days
• C. ≤90 days
• D. No limit

Answer: (C)

The main idea here is how long a Large Quantity Generator (LQG) can keep hazardous waste on site without a permit. An LQG is the generator that produces more than 1,000 kg of hazardous waste in a month, and the rules set a 90-day limit for on-site accumulation. This 90-day window is designed to keep large quantities moving off-site to a treatment, storage, or disposal facility, reducing the risks associated with storing hazardous waste for longer periods. During that time, the waste must be managed properly—containers, labeling, inspections, and spill prevention must be in place. The other time frames (like 180 or 270 days) relate to different generator categories or specific transportation/dispersion situations, not to how long an LQG may accumulate waste on-site. So for a Large Quantity Generator, the limit is 90 days.
