Community-Scale Air Toxics Ambient Monitoring (CSATAM) Projects

Air Toxics Navigation

Beginning in 2003 / 2004, the Office of Air Quality Planning and Standards, in conjunction with the Office of Transportation and Air Quality, the Office of Research and Development’s National Exposure Research Laboratory, and the ten EPA Regional Offices, has conducted periodic Community-Scale Air Toxics Ambient Monitoring grant competitions.  The resultant grants are intended to support projects of one and a half to three years duration that are designed to assist state, local and tribal communities in identifying and profiling air toxics sources, characterizing the degree and extent of local air toxics problems, and tracking progress of air toxics reduction activities.  Expected outcomes of these projects are increased state, local and tribal agency ability to 1) characterize the sources and local-scale distribution of hazardous air pollutants (HAPs), and 2) assess human exposure and risk at a local scale. These increased capabilities are expected to facilitate increased public and industry awareness, and action to adopt control measures that will reduce HAP emissions and public exposure.
