Ways to Get RSEI Results
The Risk-Screening Environmental Indicators (RSEI) model produces several different sets of results, and distributes them in different ways. This page provides links and details for some of the basic ways to get RSEI results, including EasyRSEI, the RSEI results map, and Envirofacts.

What's new in the latest version of RSEI: Version 2.3.7 (RY2017)
Each new version of RSEI incorporates the latest Toxics Release Inventory (TRI) data, as well as changes to the input data and the methodology used to process the data and present the results. The following changes were made in Version 2.3.7, released in February 2019:
- Includes TRI Reporting Years 1988-2017.
- Toxicity weights have been updated with the most recent toxicity data.
- The off-site database has been improved, with more precise locations for bigger off-site facilities, and better matching of facilities.
EasyRSEI is now an easy-to-use web dashboard that you can access through your browser with no download required. EasyRSEI contains results for the kinds of releases modeled by EPA's Risk-Screening Environmental Indicators (RSEI) model for Toxics Release Inventory (TRI) reporting years 2007-2017. A separate dashboard is available for users interested in all years of data.
RSEI Geographic Microdata
Raw RSEI model data (also known as RSEI-GM, or Geographic Microdata) for air releases, include concentrations, toxicity-weighted concentrations, and RSEI Scores for each 810 meter by 810 meter grid cell in the United States (by year). The disaggregated Microdata are very large, and contain multiple release records for each grid cell. The aggregated Microdata are a smaller dataset, and summarize impacts over all releases and chemicals for each grid cell.
RSEI Version 2.3.7 (RY2017) - Most Current Three Years Dataset (2015-2017, by year)
- The last three years of Microdata are available on the RSEI ftp site.
- Additional Microdata files will be posted soon.
Other ways to access RSEI results
Envirofacts. Facility-specific RSEI reports are available as part of the TRI view of Envirofacts. Once you have done a TRI search, on the Search Results page, click on the “Report” link in the “Risk Screening” column for that facility. You can enter any place name or ZIP code in the box below to perform a TRI search.
CalEnviroScreen. Exit CalEnviroScreen is a screening methodology that can be used to help identify California communities that are disproportionately burdened by multiple sources of pollution. CalEPA has used the tool to designate California communities as disadvantaged pursuant to Senate Bill 535.
Studies Using RSEI. RSEI is often used in academic studies, particularly for environmental justice analyses. The RSEI bibliography contains a partial list of studies and books that include RSEI data.
Other RSEI results products to download
RSEI Queries. A small Microsoft Access database containing sample queries that allow users to extract data directly from the facility-level RSEI tables, which are distributed in separate relational database. Users must have Microsoft Access 2007 or later, at least 2 GB RAM and at least 4 GB of hard drive space. RSEI Queries is for users already familiar with RSEI and Access, who have specific data needs that are not met with EasyRSEI, and who know generally which datasets they want. Click the link below to download a zipped file containing both databases and a help function with additional information on how to access the data. RSEI Queries V2.3.7 contains TRI data from 1988 through 2017, as frozen in the fall of 2018 for the TRI National Analysis dataset.

RSEI CSV files.This is the same facility-level data as in RSEI Queries, but the format is a series of comma delimited (CSV) files. The RSEI data dictionary describes each table and field, and contains links to download each table in CSV and Microsoft Excel formats. RSEI CSV files are also available on the RSEI ftp site.Exit
RSEI crosswalks and shapefiles. RSEI crosswalks allow you to transpose data from the RSEI grid to Census blocks, and shapefiles provide grid geometry for mapping microdata. Both sets of files are available on the RSEI ftp site.
U.S. census block-level data translated onto the RSEI Grid. More information on how the census files are created is contained in the RSEI methodology document.
