2005 National-Scale Air Toxics Assessment Results for the Region
*Note about effect of inaccuracies in facility emissions
Where a facility is under investigation for under-reporting emissions, the NATA results should be viewed as possibly underestimating the risk resulting from emissions from that facility. In the vicinity of such a facility, the contribution of point sources to risk may be underestimated. The Tonawanda area is one such area in the Region. Monitoring data and recent EPA investigations have confirmed that emissions of certain toxic compounds are significantly higher than those reported in the 2005 emissions data base. Readers are advised to view the Tonawanda Community Air Quality Study for a more accurate assessment of risk in this area.
The latest release of EPA's National-Scale Air Toxics Assessment (NATA) is based on air toxics emissions for the year 2005. Referred to as 2005 NATA, this is the fourth such assessment that EPA has published.
The purpose of NATA is to identify and prioritize air toxics, emission source types and locations which are of greatest potential concern in terms of contributing to population risk. EPA uses the results of these assessments in many ways, including:
- To work with communities in designing their own local-scale assessments,
- To set priorities for improving data in emissions inventories, and
- To help direct priorities for expanding and improving the network of air toxics monitoring.
The purpose of this EPA Region 2 web page is to support access to and use of the 2005 NATA results. Many of the links from this site refer to material that may be reached from the 2005 NATA website as well. Check the 2005 NATA page for postings of news about 2005 NATA.
