National Scale Air Toxics Assessment - (NATA)

NATA is a National-Scale Air Toxics Assessment to characterize potential public health risks from exposure to air toxic emissions. The U.S. Environmental Protection Agency (EPA), mandated under the Clean Air Act to control air pollutants, designed and implemented a national study to prioritize efforts to address the sources of air toxic pollution. These sources include source categories such as mobile sources, power plants, factories and any other source category included in the National Emissions Inventory.

The Commonwealth of Virginia, in cooperation with EPA, participates in projects to determine and prevent public health impacts of air toxic emissions. NATA provides an additional tool to address potential areas of health impacts to citizens. EPA released the 2005 study in 2011 and the 2011 study in 2015.
