How to File a Complaint

Filing complaints with the appropriate agency is important for two main reasons. First, it helps lead to the issue being resolved quickly. If the enforcing agency notifies Max of a violation, there can be a quicker fix – this potentially means less harm done to the environment and/or community. Secondly, complaints help to build a better record. A more robust record is a tool agencies can use to see a clearer picture about operations. For example, compliance histories can reveal patterns of violations that point to bigger issues like failing equipment or structural flaws in operations, which can ultimately be remedied through permit modifications or updates.


  • Gather as much documentation as you safely can.
    • Be sure you have legal access to all areas you access and avoid any situations that may result in injury.
  • Take photos or short videos when possible. Digital photos are ideal because they can be time and date stamped. Photos taken on your smartphone can also be location-stamped, which helps the enforcing agency verify a violation. Check your settings to enable geo-tagging on your phone.
  • If your photos or videos cannot be location-stamped try to include relevant landmarks like roads or signs, that will help the enforcing agency to verify the complaint.
  • If you are not able to take photographs, simply jot down handwritten notes as soon as you’re able. Be sure to include the time of day and location and as much detail as you can about your experience.
