Accumulation Limits for Small Quantity Generators

A small quantity generator (SQG) is defined as one that generates between 100 kg (220 lb) and 1,000 kg (2,200 lb) of nonacute hazardous waste per calendar month and is subject to less stringent rules compared to large quantity generators (LQGs). To maintain SQG status, one must not exceed the onsite accumulation limits for the following three waste types:

  1. Nonacute hazardous waste: 6,000 kg (13,200 lb). An SQG exceeding this onsite accumulation limit becomes a storage facility that requires a RCRA permit. [§262.34(f)]
  2. Acute hazardous waste: 1 kg (2.2 lb). (Remember, acute wastes include P-listed wastes, F020–F023, and F026–F027.) An SQG exceeding this onsite accumulation limit becomes a fully regulated LQG. [§261.5(f)(2)]
  3. Cleanup residue from spills of acute hazardous waste: 100 kg (220 lb). An SQG exceeding this onsite accumulation limit becomes a fully regulated LQG. [§261.5(f)(2)]
