State and federal hazardous waste regulations classify hazardous waste generators into three categories based on the amount of hazardous waste (HW) they produce (generate) each month or have in storage on-site. Conditionally Exempt Generators (CEGs), the least regulated category, generate less than 220 pound of hazardous waste in a month and have less than 2,200 pounds of hazardous waste in storage. Large Quantity Generators (LQGs), the most regulated category, generate more than 13,200 pounds of hazardous waste in a month or have more than 13,200 pounds of hazardous waste in storage. Small Quantity Generators (SQGs) fall between these two categories (see table below). There is an exception to the general rules for CEG and SQG status. When a generator generates more than 2.2 pounds of acutely hazardous wastes (P-listed), this automatically places one in the Large Quantity Generator category.
