Ecology Report: Washington State PM Emissions data (2011)
Washington State PM Emissions data (2011)
An air emissions inventory is an accounting of the amount of air pollution emitted by various sources. Every year, Ecology and the local clean air agencies inventory facilities with air operating permits. This is called a point source inventory. Every three years, Ecology inventories many additional sources such as motor vehicles, wood stoves, outdoor burning, agriculture, and natural sources. Several inventory summaries are available below.
