Annual air quality registration

If you emit air pollution, you will most likely be regulated by your local clean air agency or Ecology. This may require registering annually. Most sources pay a yearly fee based on the amount of air pollution they produce and report their emissions. Some smaller sources just report their emissions.

Registration program

Tracking emissions helps us keep Washington's air healthy. To ensure businesses are meeting air quality requirements, we regularly inspect registered sources.

A local clean air agency needs to know when a business:

  • Expands operations.
  • Adds equipment.
  • Changes ownership.
  • Closes.

Determine which local clean air agency issues your permit. Each agency has its own registration process. If an agency other than Ecology issues your permit, contact them.
