Air Emissions Inventory

An air emissions inventory is a listing of the amount of air pollution emitted by various sources. Every year, Ecology and the local air quality agencies inventory large businesses.  Every three years, Ecology inventories many additional sources such as motor vehicles, woodstoves, outdoor burning, agricultural sources, and natural sources. Several inventory summaries are available for download below.

The agency or office responsible for each facility is noted in the downloadable spreadsheet. Contact the local air agency or Ecology office for questions and the most up-to-date information for individual facilities.
