EJAir - OAR's Environmental Justice Web Site


EPA has developed tools such as maps, calculators, databases, and other searchable systems that you can use to view and gather information about rules, facilities and air pollution emissions. See also Where You Live page for more tools.

Air Pollution Mapping Tools and Databases:

  • Air Data - AirData gives you access to air quality data collected at outdoor monitors across the United States. data will help you better understand air quality in your community. Other sources of air data are available including: AirNow, AirCompare, Air Trends, Air Emission Sources, National Emissions Inventory, AQS, CASTNET, Remote Sensing, etc.
  • Community-Focused Exposure and Risk Screening Tool (C-FERST) - is still under development but will link to and build upon other community-focused tools, and it will provide state-of-the-science approaches for characterizing community exposures to environmental contaminants that lead to cumulative risks. These tools include information, strategies, human exposure models, databases, sampling/analytical methods, GIS maps, and web applications.
  • National Air Toxics Assessment (NATA)- NATA is EPA's ongoing comprehensive evaluation of air toxics in the U.S. EPA developed the NATA as a state-of-the-science screening tool for State/Local/Tribal Agencies to prioritize pollutants, emission sources and locations of interest for further study in order to gain a better understanding of risks. 
  • Toxics Release Inventory (TRI) Program - provides communities with information about toxic chemical releases and waste management activities and to inform industry, government, non-government and the public on chemical releases. You can search by zip code for a report of TRI chemical releases in your neighborhood.


  • Diesel Emissions Quantifier (Quantifier) - an interactive tool that can help evaluate clean diesel projects by estimating emission reductions, cost effectiveness, and health benefits The Quantifier has been developed as a tool for those without modeling experience.
  • Greenhouse Gas Equivalencies Calculator - can help you understand and translating abstract measurements into concrete terms you can understand and may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.

Other Databases:

  • The US Census Bureau’s interactive mapping tool, American Fact Finder Exit EPA disclaimer is a data dissemination tool for accessing and mapping Census 2000 and other census data.
  • Clean Air Markets - Interactive Mapping - provides supplementary maps that allow the user to display geo-spatial data on an interactive 3D platform. The maps come in the form of a KMZ file (a compressed KML file) that is downloaded directly to your computer.
  • Clean Energy eGRID - The Emissions & Generation Resource Integrated Database (eGRID) is a comprehensive source of data on the environmental characteristics of almost all electric power generated in the United States. eGRID is unique in that it links air emissions data with electric generation data for United States power plants.

Other Resources:

  • Community-Based Risk Assessment - Community-based risk assessment (CBRA) is an approach to investigate multiple chemical and non-chemical stressors faced by a community while working in partnership with the community to instill confidence and trust among the public.
  • EPA’s Freedom of Information Act (FOIA) Home Page - provides information for requesting documents under FOIA. The FOIA applies only to federal agencies. It does not apply to records held by Congress, the courts, or by state or local government agencies. Each state has its own public access laws that should be consulted for access to state and local records.
  • Green Communities Toolkit - toolkit provides step-by-step guidelines for planning and implementing sustainable actions at the local level. Instructions include how to conduct a trends analysis and develop a future community vision.
  • iTree Exit EPA disclaimer - a state-of-the-art, peer-reviewed software suite from the USDA Forest Service that provides urban forestry analysis and benefits assessment tools. The i-Tree Tools help communities of all sizes to strengthen their urban forest management and advocacy efforts by quantifying the structure of community trees and the environmental services that trees provide.
  • Superfund Community Involvement Toolkit - This Web-based toolkit provides a guide for community involvement in EPA’s Superfund process. Although intended for EPA staff, this toolkit includes useful information on communication strategies, conflict resolution, and dealing with the media.

Regulatory actions:

  • Rulemaking Gateway - site provides a portal to EPA’s priority rulemaking for all media (air, water, waste). The site allows you to sort rules by topic, effect, phase in the regulatory process, or other specific criteria such as Environmental Justice (EJ).
  • Regulations.gov - an online portal where users can find information about, and comment on, all agencies' rules.
