Generator status

Most businesses have dangerous waste. Learn which dangerous waste generator category you are in based on how much waste you generate or keep on site. 

Which category is my business in?

If you have dangerous waste, you need to determine whether you are a small, medium, or large quantity generator. Take the highest amount you generate in any month, and compare it to these categories:

Generator status Amount of 220-pound QEL dangerous waste Amount of 2.2-pound QEL dangerous waste

Small quantity generator (SQG)

Generate less than 220 pounds per month.

Accumulate less than 2,200 pounds at any time.
Generate or accumulate less than 2.2 pounds of waste with these codes:
all P codes * | WT01
F020 | F021 | F022
F023 | F026 | F027

Medium quantity generator (MQG)

Generate between 220 and 2,200 pounds per month.

Accumulate less than 2,200 pounds at any time.
There is no MQG status for waste with a 2.2 quantity exclusion limit. 

If you have more than 2.2 pounds in any month, you are large quantity generator.

Large quantity generator (LQG)

Generate 2,200 or more pounds per month.

Accumulate more than 2,200 pounds at any time.
Generate or accumulate 2.2 or more pounds of waste in these codes:
all P codes * | WT01
F020 | F021 | F022
F023 | F026 | F027

* Residues, contaminated soil, water, or other debris from the cleanup of a spill of any chemical designated on the "P" discarded chemical products list have a 220-pound limit.

What is a quantity exclusion limit (QEL)?

It's a weight limit that divides generators into status categories (small, medium, or large quantity generator). Designating your waste will give your waste a code that will help you determine its QEL as 220 or 2.2 pounds. Most dangerous wastes have a 220-pound QEL, but some are limited to 2.2 pounds because they are dangerous in small amounts.

QELs apply to the total amount of dangerous waste each month, not each individual waste stream. For example, if you have three different wastes with 220-pound QELs, you must add the weight of those wastes together. If those three wastes together weigh 250 pounds in one month, you would be a medium quantity generator.

Does my business generate waste?

Designate your waste — is it dangerous? will help you learn whether your company generates dangerous waste.

How much does my business generate?

Counting dangerous waste explains how to measure the amount of your waste. We call this process "counting," as in counting up the pounds of waste generated each month.

What is an XQG?

For the Dangerous Waste Annual Report, a facility is in XQG status when they do not generate dangerous waste in a calendar year. Even if they did not generate dangerous waste, the facility is required to submit an annual report if they:
