How to Obtain an EPA Identification Number

What is an EPA Identification Number?

An EPA hazardous waste generator identification number is a unique number that is assigned to facilities that generate specified amounts of hazardous waste or engage in other hazardous waste activities. It is used by states and EPA to track hazardous waste.

The number is 12 characters long. The first two characters are the postal code for the state ("ID" for Idaho). The third character can be a letter or a number. The next 9 characters are numbers.

A complete identification number looks similar to the following: IDR000123456.

Who Needs an EPA Identification Number?

If you generate more than 220 pounds (100 kilograms) of hazardous waste or
2.2 pounds (1 kilogram) of acutely hazardous waste in any calendar month, you need an EPA identification number. Also, if you accumulate more than 2,200 pounds (1,000 kilograms) of hazardous waste at any one time, you must obtain an EPA identification number.

In addition to generators, companies that transport hazardous waste and facilities that store, treat, or dispose of regulated quantities of hazardous waste generated by facilities must also have EPA identification numbers. Typically, the requirement applies to entities engaged in the following types of activities:

  • Hazardous waste generation
  • Hazardous waste transportation
  • Hazardous waste treatment, storage, and disposal
  • Hazardous waste fuel marketing
  • Hazardous waste fuel burning
  • Used oil fuel marketing
  • Used oil fuel burning
  • Used oil transportation and transfer
  • Used oil processing and re-refining
  • Large quantity universal waste handling
  • Subpart K academic lab activity
  • Hazardous secondary material (HSM) activity

Hazardous waste transportation entities based in another state that already have an EPA identification number do not need to apply for an EPA identification number in Idaho. However, out-of-state transporters should contact the Idaho Transportation Department at (208) 334-8688 for Port of Entry or trip permit information.

Does My Business in Idaho Already Have an EPA Identification Number?

Your business may have been previously assigned an EPA identification number. If so, the number may still be valid or it may need to be updated before using. To find out if you already have a valid number or if it needs to be updated, contact DEQ's Hazardous Waste Management Program at (208) 373-0502.
