Annual air quality registration
If a business emits air pollution, it is probably regulated by Ecology or a local clean air agency. This may require registering every year. A business must pay a yearly fee based on the amount of air pollution they produce and they must report their emissions.
Tracking emissions helps us keep Washington's air healthy. To make sure businesses are meeting air quality requirements, we regularly inspect registered sources.
The permitting agency (Ecology or a local clean air agency) for your area needs to know when a business:
- Expands operations.
- Adds equipment.
- Changes ownership.
Figure out 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.
