Targeted Airshed Grants Program

The Targeted Airshed Grants program assists local, state, and tribal air pollution control agencies with developing plans and conducting projects to reduce air pollution in nonattainment areas that EPA determines are the top five most polluted areas relative to ozone, annual average fine particulate matter (PM2.5), or 24-hour PM2.5 National Ambient Air Quality Standards (NAAQS). The overall goal of the Targeted Airshed Grant program is to reduce air pollution in the nation’s nonattainment areas with the highest levels of ozone and PM2.5 ambient air concentrations. Congress authorized this program in 2010 and every year since 2015. This page includes information about the current request for applications. Information on grant recipients is also available.
