EPA EJSCREEN

The EPA’s environmental justice screening and mapping tool (EJSCREEN) provides a nationally consistent dataset and approach for combining environmental and demographic indicators. This tool allows the user to display this information and includes a method for combining environmental and demographic indicators into environmental justice indexes.

EJSCREEN includes:

11 Environmental Indicators

1. National-Scale Air Toxics Assessment (NATA) air toxics cancer risk
2. NATA respiratory hazard index
3. NATA diesel PM
4. Particulate matter
5. Ozone
6. Traffic proximity and volume
7. Lead paint indicator
8. Proximity to Risk Management Plan (RMP) sites
9. Proximity to Hazardous Waste Facilities
10. Proximity to National Priorities List (NPL) sites
11. Wastewater Discharge Indicator (Stream Proximity and Toxic Concentration)

6 Demographic Indicators

1. Percent Low-Income
2. Percent People of Color
3. Less than high school education
4. Linguistic isolation
5. Individuals under age 5
6. Individuals over age 64

11 Environmental Justice Indexes (which is a combination of environmental and demographic information)

1. National Scale Air Toxics Assessment Respiratory Hazard Index
2. National Scale Air Toxics Assessment Diesel PM (DPM)
3. Particulate Matter (PM2.5)
4. Ozone
5. Lead Paint Indicator
6. Traffic Proximity and Volume
7. Proximity to Risk Management Plan Sites
8. Proximity to Treatment Storage and Disposal Facilities
9. Proximity to National Priorities List Sites
10. Wastewater Discharge Indicator

Each Environmental Justice index combines demographic indicators with a single environmental indicator. This tool provides a number of capabilities including:

• Color coded mapping
• The ability to generate a standard report for a selected area
• Comparisons showing how a selected area compares to the state, EPA region or the nation
