Area/Neighborhood Sources

Area/Neighborhood Sources of Air Pollution

Area sources are smaller sources of air pollution, such as drycleaners, gas stations, paint & auto body finishers, etc.  Area sources of pollution also include emissions from consumer products (deodorants, air fresheners, etc.), fireplaces, backyard wood burning, road dust and farming operations.

Area Sources – Hazardous Air Pollutants
EPA’s National-Scale Air Toxics Assessment defines area sources as pollution sources that generally have smaller emissions on an individual basis than major “point” sources and are often too small or ubiquitous in nature to be inventoried as individual sources. “Area sources” include facilities that have air toxics emissions below the major source threshold as defined in the air toxics sections of the Clean Air Act and thus emit less than 10 tons of a single toxic air pollutant or less than 25 tons of multiple toxic air pollutants in any one year. Area sources include smaller facilities, such as dry cleaners. “Other sources” include sources such as wildfires and prescribed burnings. NATA does not provide a breakout of more detailed area source categories. NATA does not include information on diesel emissions from point sources.
