Notification of dangerous waste activity

If you manage dangerous waste under the Resource Conservation and Recovery Act (RCRA) and Washington State Dangerous Waste Regulations you are required to notify us. When we receive the notification, we issue the site an EPA/State Identification (ID) Number. This is to ensure that dangerous waste is managed safely from the moment it is generated to its final disposal (cradle-to-grave).

What is an EPA/State ID Number?

An EPA/State ID Number identifies a single geographic location for a:

  • Site that generated regulated amounts of dangerous waste.
  • Transporter of regulated quantities of dangerous waste.
  • Facility that transfers, stores, treats, recycles, or disposes dangerous waste.

The EPA/State ID Number satisfies both the federal and state regulations for reporting dangerous waste activities. It is not a license or permit.

What is an EPA/State ID Number used for?

It is used to identify your site on:

How to apply for an EPA/State ID Number

To apply for a EPA/State ID Number you must request and complete the Dangerous Waste Site ID form. The first step in applying is to look up the address for the site where you are generating dangerous waste.

If your site:

  • Doesn't already have an EPA/State ID Number assigned to it, select "New notification of Regulated Waste Activity" on the form in section 1.
  • Already has an EPA/State ID Number assigned to it, select "Reactivate Site Identification Number" on the form in section 1.

Note: EPA/State ID Numbers are not transferable to other physical locations.

If your business moves to a new location and continues to generate hazardous waste, you must:

  1. Withdraw the EPA/State ID Number for the old location.
  2. Apply for an EPA/State ID Number for the new location or reactivate a previously withdrawn number for the new location.

How do I notify for other waste activities?

If you decide to manage your waste under the following circumstances, you must fill out the appropriate addendum forms and mail those to Ecology. 

If your site has an EPA/State ID Number, you must submit a pre-printed Site ID form with your addendums.  The pre-printed Site ID form can be found in TurboWaste.  If you do not have access to TurboWaste, please contact us.


Episodic generation

An episodic event is a planned or unplanned waste event that would normally bump your generator status to a larger category. Only medium quantity and small quantity generators can choose to use this rule. 

To start managing your waste under the episodic event requirements, you must:

  • Fill out and mail the Episodic Addendum with your updated Site ID form to Ecology.
  • Wait for approval before managing your waste as episodic, if you have submitted a petition to have a second event.
  • Notify your regional office by phone within 72 hours if the event is unplanned.

How do I revise my information or withdraw the EPA/State ID Number?

You can login to TurboWaste to submit a revised notification to withdraw or change previously submitted information. All information can be updated electronically except legal ownership (section 9a).

Once an EPA/State ID Number is assigned to a site, it stays active until you withdraw it. This is true for "one-time only" sites and sites that regularly generate dangerous waste.

 An EPA/State ID Number can be withdrawn when: The form must:
  • Have an original, wet ink signature by an authorized representative for your site.
  • Be mailed to the address at the top of the form.
Note: We will return all forms that do not have an original, wet ink signature. Copies, faxes, or emails are not accepted.
