What is Generator Status?

Businesses that produce dangerous waste are called “dangerous waste generators.” Generators are separated into categories, based on how much waste they generate or keep on site:

Every business in Washington is legally required to know if any of their wastes are dangerous and how much dangerous waste they generate each month. Most businesses generate at least a small amount of dangerous waste. Their generator status determines which dangerous waste rules apply.

* Residues, contaminated soil, water, or other debris from the cleanup of a spill of any chemical

What is a quantity exclusion limit (QEL)?

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

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?

Count Dangerous Waste explains how to measure the dangerous waste that your business creates. The regulations refer to this process as “counting,” as in counting up the pounds of waste generated each month.

What is an XQG?

For the purposes of 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:
