DEQ Environmental Complaints

As one of DEQ's highest priorities, the Environmental Complaints Program is a customer-oriented process designed to address citizens' environmental complaints.

The program's two main goals are to:

  • Provide rapid response to each environmental complaint
  • Bring about regulatory compliance through a consistent and structured process.

Oklahoma DEQ's Environmental Complaints Program is unlike any other state's complaint program in that specific timelines for communication with the complainant have been established within DEQ's regulations. The program has a uniform investigation process, a central repository for all complaint records, and direct continuous involvement with each citizen who lodges a complaint.

Do you have an environmental complalnt?

To file a complaint, you can call the DEQ Environmental Complaints Hotline, at (800) 522-0206. Or, if you would like to file an environmental complaint electronically, you can use the online form below.

For DEQ to adequately address your complaint, we need you to provide us with specific information. Please describe your complaint in as much detail as possible, including when you first noticed the problem, how often it occurs, who is responsible, and where the problem is specifically located. Please provide an address or detailed finding directions to the complaint site beginning at the nearest major intersection.

To receive updates concerning your complaint, leave us your name, mailing address and phone number on the online form. This enables our investigators to contact you for additional facts and provide you feedback on the investigation. Upon request, we will keep this information confidential, which will protect your identity and contact information from release on public records, unless ordered by a District Court. If this is your preference, select "Confidential" in the drop down box. Of course, please feel free to remain anonymous.

Regardless of the nature of the situation, or whether or not you choose to Ieave contact information, rest assured that DEQ will seriously consider the information provided and we appreciate the time you took to inform us of your concerns.
