US EPA has released a new version of BenMAP

Here is the description of BenMAP:

BenMAP is a Windows-based computer program that uses a Geographic Information System (GIS)-based to estimate the health impacts and economic benefits occurring when populations experience changes in air quality. BenMAP is powerful enough to perform a comprehensive benefits analysis but simple enough for non-technical users to estimate benefits after a short tutorial. Analysts have relied upon BenMAP to estimate the health impacts from air quality changes at the city and regional scale, both within and beyond the U.S. BenMAP includes nearly all of the information users would need to start performing a benefits analysis; advanced and non-U.S. analyses can customize the program to address their policy question. Because BenMAP is based on a GIS, the results can be mapped for ease of presentation.

Some of the purposes for which BenMAP is used include the following:

1. Generation of population/community level ambient pollution exposure maps;
2. Comparison of benefits across multiple regulatory programs;
3. Estimation of health impacts associated with exposure to existing air pollution concentrations;
4. Estimation of health benefits of alternative ambient air quality standards;
5. Performance of sensitivity analyses of health or valuation functions, or of other inputs; and
6. Hypothetical, or “what-if,” type analyses.
