What’s That Smell?

Did you realize that Kentucky has an odor standard? Under Kentucky Air Quality regulations, the Division for Air Quality is responsible for ensuring compliance with the Ambient Air Quality Standards as referenced in the Kentucky Administrative Regulations (KAR). In 401 KAR 53:010, the secondary odor standard states “at any time when one volume of ambient air is mixed with seven volume units of odorless air, the mixture must have no detectable odor.” This means that Kentucky has a regulatory standard for you to control odor leaving your facility. But beyond the regulations, odor control today can be leveraged for public relations and proof that your facility is being a good steward and neighbor to the community.

Odor control can be broken down into five basic steps:

  1. Understand the source of the odors.
  2. Understand the type of odors that may involve sampling and analysis.
  3. Utilize process controls, if applicable, to control odor generation and release. If odors at your facility are the result of operational upsets or improper operation, chances are that an add-on control technology is not the answer to your problems.
  4. If your facility is operating properly and you are still faced with an odor issue, choose an add-on control specific to your facility and specific to your odors. For more information, click here.
  5. Communicate your efforts to the community. A good example can be found in King County, Washington.

Oftentimes, a facility may invest in an odor control technology without fully understanding the problem; this potentially wastes money and resources without solving the problem.
