Welcome to EasyRSEI, where you can access results and data from EPA's Risk-Screening Environmental Indicators (RSEI) model, Version 2.3.12.

RSEI Scores add context to chemical data reported by facilities to the Toxics Release Inventory (TRI) from a relative risk-based perspective. RSEI Scores are calculated as unitless values that account for the magnitude of chemical releases, the fate and transport of the chemicals within the environment, the size and locations of potentially exposed populations, and the chemicals’ relative toxicities. Chemical releases to air or water are modeled and are combined with exposure assumptions and estimates, toxicity information, and population estimates to calculate these risk-related scores. RSEI Scores are available for modeled releases and transfers (air releases, water releases, and transfers off site to publicly owned treatment works (POTW) and to off-site incineration facilities). RSEI Score results incorporate toxicity information for both cancer and noncancer human health effects. RSEI Score-Cancer and RSEI Score-Noncancer results are also provided so users can examine those health effects separately.

RSEI Hazard results add context to chemical data reported by facilities to the TRI from a relative hazard-based perspective. For these hazard-based results, no exposure modeling or population estimates are involved. Hazard-based values are calculated by multiplying reported chemical quantities (such as pounds released into the air) by a quantitative value (weight) that expresses the toxic potential (hazard) of the chemical(s) involved. These toxicity-weighted quantities account for their magnitude (e.g., how much is released to the environment) and also their relative toxicities (e.g., how potent are the chemical(s) in causing harmful health effects). RSEI Modeled Hazard results are calculated only for the modeled releases and transfers pertaining to RSEI Score as mentioned above, and RSEI Hazard results are calculated for all chemical waste management activity quantities reported to TRI.

RSEI Modeled Pounds are the chemical release and transfer quantities that are used for RSEI modeling as mentioned above. TRI Pounds are the quantities for all waste management activities as reported to the TRI. Both of these pounds-based results do not consider any adjustments for toxicity or for exposure potential and population size.

How to Use RSEI Results

RSEI does not provide a risk assessment, so it is inappropriate to use it to:

  • Conclude that a particular chemical release is causing harm to a specific population or location,
  • Draw conclusions or make decisions about the risk posed by any particular facility, or
  • Draw conclusions about individual risk or generate quantitative risk estimates.

High RSEI Scores (relative to other RSEI Scores) can be used to identify areas that may warrant further investigation. High RSEI Scores do not conclusively demonstrate sources of risk. If a facility receives a high RSEI Score, it does not necessarily mean that the facility is harming people around it, or that the facility is not following applicable laws and regulations. If your community, or a facility in your community, has high RSEI Scores, you could use that information to help you decide if and what kind of further investigation is warranted.

This map allows you to view and select facilities by location. You can further refine your selection (by chemical, year, etc.) using the Filters and Options button, or click Summary or Analysis at the left to investigate your data further. Click Report for a printable summary of RSEI data for your current selection.

Note: TRI facilities located in Indian country must indicate the relevant tribe on annual TRI reporting forms. For TRI facilities within 10 miles of Indian country, EPA uses the US Census Bureau 2014 tribal boundary layer data and Bureau of Land Management Alaska State Office data. The tribal boundary locations identified are suitable only for general spatial reference and do not necessarily reflect EPA's position on any Indian country locations or boundaries, or the land status of any specific location.

Some facilities that report to the TRI report transfers of toxic chemicals in waste that are sent off-site to another facility in a different location for further waste managment. Chemicals reported to the TRI as transferred off site are sent to off-site facilities for the purposes of recycling, energy recovery, treatment, or disposal.

RSEI models certain off-site transfers (transfers to publicly owned treatment works and to off-site incineration facilities) and produces RSEI Scores for those transfers, which are included in the other pages of this dashboard. This page does not show RSEI Scores, but includes all off-site transfers and shows the number of pounds transferred, as well as the RSEI hazard-based results (toxicity-weighted pounds). Toxicity-adjusted quantities give more context and greater significance to the more toxic chemicals by considering a chemical’s toxicological potential to cause harm. However, hazard-based results should be interpreted carefully; in some cases, high RSEI Hazard or RSEI Modeled Hazard values may not be associated with high potential exposure or high potential risk.

The map below shows the off-site transfers for your current selection. You can select origin and/or receiving states using the drop-down menus, or select individual facilities in the tables. By default, individual facilities and transfers will show on the map only if one receiving location is selected. To manually show transfers based on your current selection, select the "Show" button below. You can hide them again by clicking the "Hide" button. You can make additional selections, such as for origin location, chemical, industry, and other fields, by using the Filters and Options button.

NOTE: Hazard values on this page and in the Off-Site Report reflect all off-site transfers reported to TRI. Elsewhere in EasyRSEI and in other RSEI data products, off-site transfers to certain incineration facilities that also report on-site releases to TRI are not included, to avoid double-counting the same potential impact. Since on-site releases are not included on this page or in the Off-Site Report, no double-counting is possible, and all transfers are included.

Each line on the map below represents transfers from an origin facility to a receiving facility. Hover over a line on the map to see details of the transfers. Click on a line to restrict the charts on this page to just those transfers.

Summary of Selected Data

Trend for Selected Data

RSEI scores are calculated estimates of relative potential human health risk based on screening-level modeling of toxic chemicals in the environment, like in the air around a facility or in the water downstream from a facility.

RSEI often uses simplified data and worst-case assumptions for modeling. RSEI results should be followed up with additional analyses and investigation before drawing any conclusions or making decisions about potential risks posed to any population group. See How RSEI Should Be Used for more information.

Use the filter options under the icon at the top right to change the value shown in these charts (RSEI Score, RSEI Hazard, etc.).

This chart shows the selected RSEI value by year for your selection set. Depending on your selection, the score for any particular facility may not represent its entire value (e.g., if you selected only certain chemicals).

Overview of Releases and Transfers

RSEI Scores are only modeled for direct (on-site) releases to air and surface waters, and for releases that may occur from transfers off site to POTW and incineration facilities. Other types of releases and transfers may also be of concern, therefore RSEI calculates hazard-based values that reflect toxicity-weighted quantities for the chemical amounts involved.

The category for modeled off-site transfers includes transfers to off-site incineration to facilities that already report to TRI. The value for TRI Pounds includes these transfers, but RSEI drops them before calculating hazard or scores. In the table above, these transfers are included in the first column of values, but not the second or third.

Top Facilities

Top Chemicals and Industry Sectors

Some of the top facilities in this set reported releases or transfers of chromium and/or chromium compounds, which can be a major contributor to RSEI Scores. Toxicity can vary widely across the various chemical forms of chromium, and facilities do not report which specific compound or form they release or transfer. The RSEI model makes certain assumptions about the percent of total reported chromium and chromium compounds from each facility that is hexavalent (the most toxic form of the metal), using facility or industry-level data derived from the National Emissions Inventory (NEI) and other EPA data sources. To the extent that the RSEI assumptions differ from what is actually released by each facility, the risk-related impacts of chromium to public health may be over- or under-estimated.
