What is the accumulation time limit for hazardous waste on-site for an LQG?

• A. 180 days
• B. 30 days
• C. Less than 90 days
• D. 90 days or less

Answer: (C)

Understanding how long a Large Quantity Generator can hold hazardous waste on-site is about the allowable accumulation window. For an LQG, hazardous waste may be accumulated on-site for up to 90 days. The clock starts when the first waste is placed into an accumulation container, and you must move that waste off-site for treatment or disposal within 90 days. This limit helps minimize risk by ensuring hazardous waste isn’t stored on-site indefinitely, while still giving the generator time to arrange transportation. So the correct concept is that the limit is 90 days or less, meaning 90 days is included. The 180-day figure applies to Small Quantity Generators, not LQGs, and a 30-day limit is too short for typical LQG operations.
