Hazardous Waste Generators - Generator Status

Table

There are three categories of hazardous waste generators: conditionally exempt small quantity generators (CESQG), 100-1000 kg/month generators, and large quantity generators.

CESQGs generate no more than 100 kg/month of hazardous waste and never store more than 1000 kg of hazardous waste on site ( 40 CFR §261.5 ).

100-1000 kg/month generators, usually referred to as small quantity generators (SQGs), generate more than 100 kg/month but less than 1000 kg/month ( 40 CFR §262.34 ).

Large quantity generators generate 1000 kg of hazardous waste per month or more ( 40 CFR §262.34 ).
