Conditionally Exempt Small Quantity Generator (CESQG)

Additional information for automotive repair and autobody shops who generate less than 220 pounds or 26 gallons of hazardous waste per month.

The hazardous waste regulations that apply to you depend on the amount of hazardous waste you generate per month. If you generate less than 220 pounds or 26 gallons of hazardous waste per month, you are considered a Conditionally Exempt Small Quantity Generator (CESQG). While the Illinois EPA does not require CESQGs to have an EPA generator identification number, the Secretary of State, under the Illinois Vehicle Code 625 ILCS 5/5-301 (i) (4), requires all auto repairers and rebuilders to either have an EPA generator identification number or a Certificate of Exemption. Therefore, if you generate less than 220 pounds or 26 gallons of hazardous waste per month, you will need to complete the Certificate of Exemption to keep on file in the event that the Secretary of State should require proof of an EPA generator identification number. The Illinois EPA does not require a copy of this Certificate.
