Three Draft Air Quality General Orders

Ecology is seeking public comments on three draft air quality general orders.


The intent of each general order is to provide a streamlined permitting process for applicants who qualify and can satisfy the conditions within the general order.


The revised general orders cover the following:


  • Asphalt plants
  • Concrete batch plants
  • Rock crushers


These updated general orders will ensure consistency with the latest 40 CFR Part 50 Federal Clean Air Act federal primary and secondary National Ambient Air Quality Standards (NAAQS), Washington Ambient Air Quality Standards (WAC 173-476-900), and Washington toxic air pollutant standards (Chapter 173-460 WAC).
