Stuff happens. One day you’re a conditionally exempt small quantity generator (CESQG) of hazardous waste, and then the next day you realize you’re a small quantity generator (SQG) of hazardous waste. Only it’s not one day that’s the issue; it’s one month, as hazardous waste generator status is determined by the volumes of hazardous waste generated monthly.
As you know, you must add up the weight of all the hazardous waste your facility generates in a month with the total weight determining your generator class. The federal rule at 40 CFR 261.5 is the RCRA regulation that helps you to determine whether you’re a CESQG, an SQG, or a large quantity generator (LQG) of hazardous waste. It specifies which wastes are counted and which are excluded from being counted.
