You can keep your hazardous waste disposal costs down
By Elizabeth M Dickinson, JD, Senior Legal Editor - EHS

You know you generate hazardous waste at your facility and you want to keep your disposal costs down. Well then you have to keep down the amount of hazardous waste you have onsite each month. If you are a large quantity generator (LQG), your responsibilities and costs will be greater than if you are a small quantity generator (SQG). You’ll have even fewer requirements to follow if you are a conditionally exempt small quantity generator (CESQG).

This table shows the volume of hazardous waste that you can have at your facility depending on your generator class, according to EPA’s hazardous waste regulations.  

Maximum/Minimum Monthly Volumes, Each Class of Generator

Class of Generator





Waste Volumes

1,000 kg or more of hazardous waste a month; more than 1 kg of acute hazardous waste a month

More than 100 kg but less than 1,000 kg of hazardous waste a month; up to a total of 1 kg of acute hazardous waste a month

Up to 100 kg of hazardous waste a month; up to a total of 1 kg of acute hazardous waste a month; up to 100 kg of any residue or contaminated soil, waste, or debris from the cleanup of a spill, onto land or water, of acute hazardous waste a month

Okay, so what’s a kilogram (kg) in terms of pounds? EPA’s regulations are full of references to unit systems other than what we normally use here in America.

Enviro.BLR.com customers have access to Units Conversion Worksheets. This series of worksheets will convert the entered quantity from the chosen units to other common units of mass, length, area, volume, pressure, and temperature.   If you plug in 1,000 kilograms on the mass tab, you will quickly find out that you have to keep your hazardous waste accumulation below about 2,205 pounds every month to avoid LQG status.
