Air Quality 101

Air Quality Permits

Here is a visual overview of the types and approximate numbers of facilities that DEQ regulates through permitting.

They run the range from least complex permits for very small emitters to very complex permits for the largest industrial facilities. Under each category there are examples of facility types.

  • Some examples of facilities where federal standards have required air toxics reductions are the larger wood products manufacturers, foundries and energy production facilities.
  • In the past 5 years, EPA air toxics standards have also applied to many medium and smaller facilities, requiring air toxics controls at dry cleaners, auto body shops and metal plating facilities.
  • DEQ partners with industry associations to provide technical assistance to hundreds of the smaller facilities each year.

Oregon has controlled air pollution through state permits since 1972 – 44 years.
