General orders for portable sources of air pollution
Certain types of businesses that emit air pollution move their operations around the state, such as:
- Portable asphalt plants
- Portable concrete plants
- Portable rock crushers
- Non-road engines used to power these operations
A business can get a general order or permit for these operations from us. However, if a business already has a valid air permit for these operations issued by a local clean air agency, we will accept that permit if it was issued after July 1, 2010.
Notify us at least 15 days before you start work in a county we oversee. Include the notification form, a copy of your valid air permit, and the fee. You must also comply with all relevant State Environmental Policy Act (SEPA) guidelines.
Contact our regional office where your project is located. If you are in another county, contact the local clean air agency to check the types of general orders they have.
