Citizen complaints

Have you seen something that may negatively impact the environment or be in violation of environmental regulations?

Use the Citizen Complaint form to report it to the MPCA.

  • Online: Citizen Complaint form — log in as a Guest (no need to create an account).
  • Phone: 651-296-6300 or 1-800-657-3864 in Greater Minnesota.

Do not use the citizen complaint form if:

  • You are reporting oil or hazardous materials spills, instead call the HTML icon Minnesota Duty Officer at 1-800-422-0798.
  • You are concerned about unsafe or unhealthy conditions at a worksite, instead file a complaint with the Occupational Safety and Health Administration (OSHA):

  • You have an environmental question or comment for the MPCA, instead please use the Ask MPCA online form.
