Generator status is measured based on how much hazardous waste a facility generates in a given month during the calendar year. Among many other requirements, the generator status then dictates how frequently the waste must be removed from the facility. U.S. EPA RCRA Subtitle C established waste generator status regulations.
Generators are divided into three categories:
- Large Quantity Generators - These facilities generate at least 1,000 kg (2,200 lbs) of hazardous waste per month, or greater than 1 kg (2.2 lbs) of acutely hazardous waste per month.
- Small Quantity Generators (SQG) - These facilities generate greater than 100 kg (220 lbs) but less than 1,000 kg hazardous waste per month and up to 1 kg (2.2 lbs) of acutely hazardous waste per month.
- Conditionally Exempt Small Quantity Generators (CESQG) - These facilities generate no more than 100 kg (220 lbs) per month of hazardous waste and up to 1 kg (2.2 lbs) per month of acutely hazardous waste.
Best Management Practices & Pollution Prevention
In order to reduce your hazardous waste generator status, reduce the toxicity of the waste generated. See other process and product specific sections for detailed suggestions.

Large and small quantity generators must meet many similar requirements under RCRA. SQGs may accumulated up to 6,000 kg of hazardous waste on-site at any one time for up to 180 days without being regulated as a treatment, storage or disposal facility (TSD) and thereby having to apply for a TSD permit. If the waste will be transported over 200 miles from the facility, SQGs are allowed to store hazardous waste on-site for 270 days without having to apply for TSD status. LQGs have only a 90-day window to ship waste off-site without needing a TSD permit. There is no limit to the amount of time a CESQG may store hazardous waste on site.
Hazardous waste generators that meet the conditions to be classified as a SQG or a LQG must:
- obtain a generator identification number;
- store and ship hazardous waste in suitable containers or tanks;
- manifest the waste properly;
- maintain copies of the manifest, a shipment log covering all hazardous waste shipments and test records;
- comply with applicable land disposal restriction requirements; and
- report releases or threats of releases of hazardous waste.
