What is a waste?

A waste is a material that you no longer need, want or use; it is something that is unusable or is intended to be discarded, such as spent solvent.

A waste is not something that you can and will use, such as leftover paint that will be used on another project.

What is a hazardous waste?

A waste is either non-hazardous — and exempt from hazardous waste regulations — or hazardous for one of the following reasons:

  • It is listed (appears on one of four lists in the Minnesota Hazardous Waste Rules)
  • It is characteristic (displays one or more of six hazardous characteristics)
  • It contains more than 50 parts per million (ppm) polychlorinated biphenyls (PCBs)

For more information, see examples of hazardous and special wastes.

Evaluating your waste

Minnesota Hazardous Waste Rules require that anyone who produces or manages a waste must carefully examine a waste's characteristics in order to determine whether or not it is hazardous.

To determine if your business produces hazardous waste:

  1. Gather information about the wastes your business produces. Talk to purchasing, production and maintenance personnel, tour production and non-production areas and inspect storage areas and dumpsters. Don't forget to include sewered and recycled wastes.
  2. Evaluate the wastes (PDF). The evaluation process will include checking to see if any of the wastes are exempt from the hazardous waste rules, determining if any of the wastes are listed in the hazardous waste rules, and determining if any of the wastes display any of the characteristics of hazardous waste. You may need to have the waste tested.
  3. Obtain a hazardous waste license if your business generates hazardous waste.

Update and manage your hazardous waste license using the Hennepin County Hazardous Waste Portal.

Use the portal to:

  • Submit annual reports electronically
  • Get real-time access to license information for all operations under your control
  • Add wastes to a license and provide supporting documents, such as test results
  • Make wastes inactive if they are no longer generated
  • Update site contact and mailing address information
  • Print copies of licensing documents, including reports, licenses and invoices

Getting access to the portal

The portal was launched in 2013 and all existing hazardous waste generators that are required to complete the annual licensing process have a portal administrator associated with their operation. If you are not yet a portal user and need to be added, you should reach out to the portal administrator for your operation to be added as a user. If you don’t know who the portal administrator is for your operation or the portal administrator is no longer with the operation, send an email to to request assistance or call 612-348-3777 and ask for the inspector on call.

More than 50% of minimal generator operations are also registered in the hazardous waste portal.

Reducing your hazardous waste fees

Businesses can reduce hazardous waste fees by reducing the amount of hazardous waste they produce. Many businesses have been able to reduce their license fees by implementing changes in their processes, equipment or products used. For more information on how to do this and, for technical assistance, see pollution prevention and waste reduction programs.
