BenMAP is a PC-based GIS program that estimates the health benefits associated with air quality changes by creating population-level exposure surfaces, estimating changes in incidences of a wide range of health outcomes associated with ambient air pollution, and then placing an economic value on these reduced incidences. BenMAP produces both point estimates and distributions of incidence and value estimates. The model is currently available in three versions.

BenMAP 3.0 (October 2008): This is the current version of the BenMAP software. This version includes a new U.S. population database. This new database incorporates improvements to the population algorithm used to allocate population to air quality modeling grids. The U.S. population database is now projected to the year 2030, and allows users to stratify incidence estimates by ethnicity, as well as the traditional variables of race, age and sex. The built in monitoring dataset has been updated to include all criteria pollutants to the year 2007. The user’s guide is now built into the BenMAP program. Finally, this version incorporates a large array of bug fixes. Note that all configuration and aggregation, pooling and valuation files constructed using previous versions of BenMAP should be compatible with version 3.0.
- BenMAP 3.0 Beta (~420 MB)
- Ozone National Ambient Air Quality Standard (NAAQS) Regulatory Impact Analysis (RIA) -- Aggregation, Pooling and Valuation file for the BenMAP model (APV file) (6.4 MB) The APV file contains information that BenMAP uses to aggregate your results, pool the health impact effect estimates and estimate the monetary value of the incidence of health effects avoided. You will need to first download and install BenMAP 3.0 to access this file.
- Ozone NAAQS RIA -- Configuration file (CFG file) (32k) The CFG file contains information regarding the health impact functions that BenMAP uses to generate a "raw" estimate of the incidence of health effects avoided. You will need to first download and install BenMAP 3.0 to access this file.
- Monitoring files: The files below contain CO, SO2 and NO2 monitoring data for the years 2000—2007. The BenMAP version 3.0 installer contains O3, PM2.5, PM10 and Lead monitoring data for these same years and so we did not provide a download link to these data here. We also provide a memo describing the approach to compiling these data.
The zip files below each contain two BenMAP database (.bdb) files. The first .bdb file contains the monitoring data for that pollutant. The second file is the “definition” of that pollutant. Simply download the zip file, and in BenMAP select “import database” under the “file” menu. First import the pollutant definition .bdb and then import the monitoring data .bdb file. Further instructions for loading .bdb files may be found in the BenMAP user manual- NO2 (zip file) (23 MB)
- SO2 (zip file) (19 MB)
- CO (zip file) (18 MB)
- BenMAP Manual and Appendices:
These manuals refer to BenMAP version 3.0. Users interested in the manual for version 2.2. should contact EPA at BenMAP@epa.gov.

- BenMAP Manual Appendices (PDF) (400pp, 6.9 MB)
- BenMAP 1.0: The legacy version of BenMAP that was used in developing the regulatory benefits analyses for the Nonroad Diesel and Clean Air Interstate rules. This version of the model is designed for regional and national-scale analyses within the Continental United States, and uses a fixed set of population data and air quality model grid definitions. Download time for this version is significant due to the large databases which support the analyses.
