Generator category

Generator category icon
Businesses that generate dangerous waste must determine their generator category each month. Generator categories include:

The amount and type of dangerous waste you produce in a calendar month determines which regulations apply. Your generator category may change from month to month.

How to determine your generator category

Step 1: Designate your waste.
This process helps you figure out what type of waste you have, including waste codes.

Step 2: Count your waste.
Total the amounts of the following:

*EHW = extremely hazardous waste (code WT01); AHW = acutely hazardous wastes that are toxic in small amounts (all P-listed and some F-listed waste codes: F020, F021, F022, F023, F026, F027).

**Spills include residue and contaminated materials from the cleanup of highly toxic waste spilled to land or water.

Step 3: Compare quantity exclusion limits (QELs) against your count to determine your monthly generator category. Use the QEL chart below to make this determination.

What are quantity exclusion limits (QELs)?

A QEL is a monthly weight limit that determines your generator category based on the amount and type(s) of dangerous waste you generated that month.

QEL chart to determine your generator category

Use the chart below to determine your monthly generator category. If your waste counts fall into more than one generator category, apply the more stringent generator category to your business. For instance, if you generated 200 pounds of dangerous waste, but 2.3 pounds of AHW, then you are an LQG.
