Hazardous waste generators are classified in one of the following three categories based on the amount of hazardous waste generated in a calendar month:
|Generator Size||Hazardous Waste||Acute Hazardous Waste|
|Very Small Quantity Generator (VSQG)||≤220 pounds||≤2.2 pounds|
|Small Quantity Generators (SQG)||220 to 2,200 pounds||≤2.2 pounds|
|Large Quantity Generators (LQG)||>2,200 pounds||>2.2 pounds|

A VSQG or SQG that exceeds monthly quantity limits due to a planned or unplanned event may be able to maintain the existing generator category if certain requirements are met. Learn more about episodic generation.
