What is the on-site accumulation limit for Very Small Quantity Generators?

• A. ≤6,000 kg
• B. ≤100 kg
• C. ≤1,000 kg or ≤1 kg acute hazardous waste or ≤100 kg of acute spill residue or soil
• D. No accumulation limit

Answer: (C)

On-site accumulation limits set how much hazardous waste a Very Small Quantity Generator can store at the facility at any one time without triggering stricter storage rules. For a VSQG, the rules specify different caps depending on the waste type: up to 1,000 kilograms of non-acute hazardous waste can be stored on site; only up to 1 kilogram of acute hazardous waste can be stored; and up to 100 kilograms of acute spill residue or soil containing acute waste can be on site. These limits exist because acute hazards require tighter controls, and keeping spill residues separate helps manage potential exposure and cleanup. Surpassing these thresholds would move the generator into a higher category with more stringent storage, labeling, and handling requirements. The other figures don’t align with these combined limits, and there is an established accumulation limit to ensure safe, compliant storage.
