Report an Air Pollution Problem

Reports from the public are essential in helping the APCD locate and address air quality issues. When you report an issue, Compliance Officers with the Louisville Metro Air Pollution Control District will investigate your report and, if warranted, can cite violators who fail to address the problem. Read the APCD's standard operating procedures (SOPs) for investigating reports about odors. 

Past odor investigations performed by the APCD are visualized in this dashboard. 

Here are the best ways to report different air pollution issues:

If an odor is affecting your immediate health and safety, call 911. If an odor is an annoyance or nuisance, here's how you can report it:

The information that will best help us investigate the odor is:

  • Where you first detected it, the date and time it was detected, and how long it lasted.
  • Any characteristics, such as chemical, sewer, flowery, burnt, strong, mild, or obnoxious.

Keep notes of your observations so they can be referenced in the future. An odor log is an easy way to track recurring odors

If you believe the odor is coming from the sewer, you can contact the Metro Sewer District directly at (502) 540-6000.
